The [International Uranium Film Festival] is the world's only traveling film festival devoted to the entire Nuclear Fuel Chain, from uranium mining to uranium tailings and nuclear waste, from Hiroshima to Fukushima and Fallujah.The film festival's schedule and more details are also available on their Facebook page.
The festival will make its way from Albuquerque (Nov. 27-28) to Santa Fe (Nov. 30-Dec. 1), to Window Rock and finally to Washington D.C. and New York City in early 2014. The founder of the IUFF, Norbert G. Suchanek of Germany, will be present at each screening along with Executive Director Marcia Gomes de Oliveira of Brazil and various producers and directors of the films. Each screening is organized by a diverse group of volunteers to bring these films to the wide screen.
Because of the tremendous impact uranium mining has had on Diné peoples, while these films are playing in the theatre of the Navajo Nation Museum, there will be several organizations coming together on the side to dialogue about the uranium legacy issues still plaguing the Navajo Nation and the new uranium mining permit applications threatening nearby communities and Sacred Sites. Community groups, residents and allies will meet for the two and a half days at the museum and in the local area. Online video streaming will be available via ustream.com during selected hours of the event.

Uranium Film Festival Comes to Navajo Nation Dec 2-4
The International Uranium Film Festival makes a stop at the Navajo Nation Museum in Window Rock, Arizona this December 2nd through the 4th, bringing three days of insightful documentaries that reveal stories of many First Nations and aboriginal peoples worldwide whose historical lands have been used for radioactive minerals mining and nuclear waste disposal - often with little regard for the health, safety, and security of the communities involved. The Southwestern United States was an epicenter of wartime and peacetime uranium mining from the Cold War onwards; the Navajo Nation only one of sadly many who have suffered its lasting ill consequences.

Chernobyl's New Safe Confinement Rises: The First Stage
After nearly two decades of administrative, political, and financial setbacks, major progress is being made now at the New Safe Confinement. Having been previously called "Ukritye" and the "Shelter Implementation Plan" over the years, the secure NSC outer shell being built over the decaying Chernobyl Sarcophagus will allow Reactor 4 to finally be safely dismantled with greatly reduced risk to the environment.
In the clip below, Vince Novak, the EBRD [European Bank for Reconstruction and Development]'s Director of Nuclear Safety discusses the construction progress and the NSC's benefits.

Radioactive Cesium Found in Rats Near Fukushima
This story from Japan illustrates how radioactive contamination can be dispersed by animal vectors, as well as weather, water, and human intervention: NHK News reports cesium has been found in the brains of wild rats in the forested area about 30km from the beleaguered Fukushima Daiichi nuclear plant.
Apodemus speciosus is actually a species called the Large Japanese Field Mouse, so I'm uncertain if the article is referring to both rats and mice, or just the Large Japanese Field Mice. The linked NHK News article contains a 1:37 video (in Japanese) which may provide a more detailed explanation. Judging from size alone, the rodents shown captured in the video look to be A. speciosus, not the typical species of domestic rat common in Japan.

[English text via Google Translate]Linked below are a few studies that may give an idea of how radiation spread by animal vectors like rats contributes to environmental contamination: when contaminated vectors are consumed by predators, if vector and subsequent predator wastes contain appreciable radioactive contamination, and also, if vectors die naturally, how much contamination is left in the soil, landfills, etc. According to one of the articles linked below, larger wildlife like deer pose a greater risk due to their larger body size, wider habitat range, and longer lifespan. Rats in particular would be a particularly important vector to study, given their affinity for human dwellings and garbage dumps. Please note that academic or library access may be needed to access the linked journal papers.
Highly Radioactive Cesium from Rat Cortex
Radioactive cesium in the 3100 Becquerels [range] was detected in rats in the wild, captured in the forest approximately 30 km from [the] nuclear power plants. An expert at Fukushima Daiichi Tokyo Electric Power Company [said] there is a need to examine continuously the impact on wildlife.
...Apodemus speciosus was captured wild in October and December last year in the forest. As a result of examining the concentration of radioactive cesium accumulated in the body of 12 mice...on average, per kilogram, from rats captured in the village of Kawauchi [measured at] 3,100 becquerels, in Kitaibaraki 790 becquerels has been detected.
Radiation dose in the air of the capture location, Kawauchi village, is in the [range of] 0.2 μSv - 3.11 μSv per hour, and [in] Kitaibaraki, where radiation dose is high, [there was a tendency to find] higher concentrations of radioactive materials in the rat[s]. The results of the survey, Yoshihisa Kubota, Sub-Leader of the National Institute of Radiological Sciences, [indicate] "There is a need to examine ... rats to study the effects of radiation to the same extent as human animals, continue to impact on wildlife of radioactive material."

Radiation Readings at Plot M Well in Red Gate Woods
Recently, we took a field trip [with a SPER Scientific portable radiation monitor in tow] to Red Gate Woods near Willow Springs, IL, home of the Plot M nuclear disposal site. The area is open to the public but a bit hard to find, located off a small side trail in the forest preserve. While radiation readings at the Plot M stone monument were essentially background-level, one of the numerous test well caps (kept padlocked) did appear to have higher than normal radiation counts, averaging about 0.1-0.3 mR/hr as seen from this short video clip.

California Truck Crash Load Contained 4g Plutonium
If you think all the hazardous radioactive material being transported across the country is safeguarded - or at least properly packaged and prepared for shipment on public thorofares - think again. The circumstances of last Tuesday's truck crash near the Mojave National Preserve are truly frightening if they're any indication of how carelessly lethal materials like plutonium might be traveling, perhaps in a vehicle rolling alongside you. From the San Bernadino Sun:
Baking soda, bunk beds, fire extinguishers - and a drum with plutonium-238. The truck that crashed Tuesday near Needles [CA] with a load of radioactive waste was a plain old commercial truck carrying plain old products.
When emergency workers checked the truck's manifest they were surprised that radioactive material was being shipped with ordinary goods. "This, in and of itself, is very alarming," said San Bernardino County Fire Marshal Peter Brierty, who also directs his agency's hazardous materials unit. Government and industry officials say shipping radioactive materials by commercial carriers is a perfectly safe, perfectly routine practice. The containers, the routes and the shipping companies are all heavily regulated, and there has never been an accident that resulted in a release of radiation, they said.
The radiation emitted by the truck's amount of plutonium-238 is trillions of times more than is allowed in drinking water, Brierty said. The four grams of plutonium involved in the crash would be roughly the volume of a pencil eraser. But that amount kicks out more than 60 curies, a measure of radioactivity. In contrast, the drinking water standard is 15 picocuries per liter, or 15 trillionths of one curie.
...
The truck, pulling two trailers, crashed into a guardrail on eastbound Interstate 40, rupturing the tractor's fuel tank and causing the rear trailer to overturn and split open. The driver was unhurt. Part of the freeway was shut down for 18 hours. The heavily shielded, 500-pound, 55-gallon drum with the plutonium was in the front of the damaged trailer, California Highway Patrol Officer Michael Callahan said. The entire cargo had to be unloaded to get at the drum.
The drum was undamaged, and there was no leakage of radiation. [But,] "What the hell is that doing in that truck?" said Robert Halstead, an expert in the transportation of nuclear waste. [read full article]

Dounreay Fuel Pellets a Health Risk on Scots Beaches?
According to the Scottish Environment Protection Agency (SEPA), nuclear fuel particles found on beaches near the defunct [Caithness] Dounreay nuclear facility in Scotland only "pose low-level risk to human health." However, the agency conceded that some pieces of higher-activity fuel rods are still washing up on public beaches. From the Edie News Center:

Fragments of nuclear fuel, which continue to turn up on beaches near the former experimental reactor, prompted SEPA to commission an enquiry into their effects on human health in 1998.More: Risk of Dounreay particles 'low' [March 14th, 2006 on BBC web]
Particles found at the site so far are "relatively low in activity." Visible skin burns could only occur if a person encountered a particle of higher activity, according to the Health Protection Agency (HPA), which carried out the research. It estimated the chances of that happening at one in 80 million.
But the report also warned of particles with a higher radioactivity being brought onto the beach from the seabed. Such particles have not been detected since monitoring began in 1999, however, the researchers said.
The HPA looked more closely at vulnerable groups, such as people walking dogs or digging for bait on the affected beaches, and the time they spent there. It considered the possibility of people accidentally swallowing or inhaling the particles, or sand from the beach being used for children's sandpits.

U.S. Seaports Deal and the Nuclear Terror Threat
The controversial Dubai Ports deal has spurred heated debate about the widsom of having foreign-owned corporations overseeing management of our national ports of entry. One of our main unsolved port security issues is the problem of uninspected freight containers, which some experts contend may be the route through which nuclear materials or devices could most easily be smuggled into the U.S. for use in a a terrorist attack. From the New York Times's "Big Problem, Dubai Deal or Not":
Only 4 percent or 5 percent of those containers are inspected. There is virtually no standard for how containers are sealed, or for certifying the identities of thousands of drivers who enter and leave the ports to pick them up. If a nuclear weapon is put inside a container — the real fear here — "it will probably happen when some truck driver is paid off to take a long lunch, before he even gets near a terminal," said [retired Coast Guard commander Stephen E.] Flynn, the ports security expert.
That is where concerns about Dubai come in. While the company in question has not been a focus of investigations, Dubai has been a way station for contraband, some of it nuclear. Abdul Qadeer Khan, the Pakistani nuclear engineer, made Dubai his transshipment point for the equipment he sent to Libya and Iran because he could operate there without worrying about investigators.
"I'm not worried about who is running the New York port," a senior inspector for the International Atomic Energy Agency said, insisting he could not be named because the agency's work is considered confidential. "I'm worried about what arrives at the New York port." [read full article, reg. req.]

UK Hospital Waste Truck Leaks Radiation
This week, a private nuclear materials handling firm in the United Kingdom apparently neglected to install a protective "plug" on a cask of radioactive hospital waste being transported by truck across Northern England, causing the cask to emit high levels of radiation during transit. "By pure chance," the radiation beam pointed downwards, away from other vehicles, and no injuries were reported. From the Telegraph UK:
More details at The Australian and BBC News Online.
A highly radioactive beam was emitted from a protective flask as it was driven 130 miles, for three hours, across northern England on a lorry, a court heard yesterday....The flask belonging to AEA Technology was being used to transport a piece of decommissioned cancer treatment equipment from Cookridge Hospital, Leeds, to the Sellafield complex, Cumbria on March 11, 2002.The radiation dose rates reportedly "were in the order of 100 to 1,000 times above what would normally be considered a very high dose rate and measurement was beyond the capabilities of normal hand-held monitoring equipment." The company responsible for handling the cask's transport, AEA Technology, "a privatised arm of the UK Atomic Energy Authority," has allegedly admitted to a series of recent safety breaches. The company was due to be fined in a court proceeding in connection with an earlier safety violations, but the court has delayed setting the final judgment in light of this new incident.
A judge was told how the container was "found to be emitting a narrow beam of radiation, of a very high dose rate, vertically down from that package base". [read full article]

St. Petersburg: Report Says Renovation of Chernobyl-Type Reactor Rushed
From the St. Petersburg Times, disturbing news about an aging RBMK-1000 type reactor being renovated for reactivation:
Report Says Renovation of Chernobyl-Type Reactor Rushed
October 8, 2004
By Vladimir Kovalev
STAFF WRITER
A series of mishaps has occurred during the renovation of reactor No.1 at the Leningrad Nuclear Power Plant, or LAES, in Sosnovy Bor outside St. Petersburg because basic safety regulations were ignored, according to a new report.
Reactor No. 1 is the oldest of four reactors at the plant and its official working life has expired, but the Federal Nuclear Power Agency is seeking to extend it. It is an RBMK-1000 reactor, the same type that caused the Chernobyl disaster in 1986, and LAES management plan to restart it this fall.
Sergei Kharitonov, a former employee of the plant and now an environmental campaigner, wrote in the report that the safety systems for the reactors were installed in a rush, in some cases by unqualified workers, breaching standards on how the work should be done, the report said.
As a result, two workers died in the spring, including a 32-year-old construction worker who fell from the wall of bloc No.1 in April and a 42-year-old fitter was crushed while working on bloc No.2 in May.
"[The management] paid most of its attention to [staff] training for the launch of bloc No.1," Kharitonov quoted LAES management as saying in a statement on July 16. "The lectures were poorly attended ... Two lectures remain to be conducted. Such a situation is unacceptable, when the bloc [No.1] is about to launched, but employees are not ready for it."

Missing Yankee Nuclear Fuel Rods Found
From the Champlain Channel WPTZ-TV
Fuel Rods Found In Pool At Plant
POSTED: 8:21 pm EDT July 13, 2004
UPDATED: 9:24 am EDT July 14, 2004
VERNON, Vt. -- Two highly radioactive pieces of spent nuclear fuel reported missing three months ago appear to have been where they were supposed to be all along.
A spokesman for the federal Nuclear Regulatory Commission said Vermont Yankee has told the NRC it found the fuel rods in the spent fuel pool at the plant. Vermont Yankee officials said last week they had found records at a General Electric laboratory in California that appeared to provide a key clue as to the fuel pieces' whereabouts.
Workers found the spent rods inside a cylinder that was sent to Vermont Yankee by GE specifically to hold the fuel segments. Searchers found the canister at the bottom of the spent rod pool and opened it up, discovering the rods late Tuesday afternoon. Vermont Yankee said it has updated its records to make sure something like that doesn't happen again.

Chernobyl Explorer: Alexander Borovoi
Dr. Alexander Borovoi is one of the people interviewed (his segment starts at 32:40) in this astounding BBC documentary from 1991, "Inside Chernobyl's Sarcophagus." Borovoi and his colleagues Viktor Popov, Yuri Buzulukov, and other "Stalkers" speak with western journalists for the first time since the accident. The scientists and BBC crew enter the Reactor 4 building taking measurements and video footage of its wreckage, in extreme haste (due to the radiation levels) and incredibly dangerous conditions. Footage had to be shot by actual cameramen working quickly, as the searing radiation and rough ground caused robotic camera rigs to mire or fail within minutes. In one segment we see a clever improvisation: the team jerry-rigged a small videocamera onto a wire remote-controlled child's toy tank. The end of the documentary is an interview with Borovoi and Popov five years later, where we revisit their dire predictions, and the surviving members of the "bio-robot" team.

[UPDATE: Borovoi's 2008 presentation detailing the state of the Chernobyl corium, or "melt." (PowerPoint on SarNet.org] 64-year old Alexander Borovoi is a brave man, and a very lucky one; he is one of the "extreme explorers" who periodically examined the inside of the Chernobyl sarcophagus to spot developing problems. From US News and World Report:

[UPDATE: Borovoi's 2008 presentation detailing the state of the Chernobyl corium, or "melt." (PowerPoint on SarNet.org] 64-year old Alexander Borovoi is a brave man, and a very lucky one; he is one of the "extreme explorers" who periodically examined the inside of the Chernobyl sarcophagus to spot developing problems. From US News and World Report:
The line between hero and victim was thin in the first frantic weeks after the accident. Firemen fought the flames but lacked instruments to tell them they faced lethal doses of radiation. Military helicopter pilots hovered in the radioactive smoke plume to smother the burning reactor with tons of sand and lead, but their bombing runs missed the mark.
Yet the catastrophe–and the chance for heroism–did not end when the fire burned out. In the months and years that followed, a band of scientists led by physicist Alexander Borovoi explored the reactor's corpse to make sure it could not reawaken. Working in a hot, dark labyrinth where lingering radiation could kill within minutes, they mapped and analyzed tons of reactor fuel remaining. It was heroism of a quieter and more effective order than had come before. "Borovoi knew what he was doing," says Harvard University nuclear physicist Richard Wilson, "and he had the imagination and common sense" to succeed.
To find the remnants, Borovoi and his men had to venture into the heart of the destroyed reactor. Robots were not up to the job; they got stuck in debris or ran amok, circuits scrambled by radiation. "We had only one kind of robots [that worked]," says Borovoi. "Biorobots–ourselves." They called themselves "stalkers." Coveralls, gloves, and a respirator were their protection–lead suits were too bulky for dashes through the reactor. A fall or wrong turn could be fatal.
Late in 1986, beyond a gantlet of highly radioactive rooms and narrow passages, the stalkers discovered a glassy, black formation resembling a giant elephant's foot. Getting a piece to analyze was not easy. It was so fiercely radioactive that the scientists could spend only seconds near it, and its surface shrugged off a drilling machine and an ax. Finally a marksman took aim with a Kalashnikov rifle. The shards gave the first clues to what had happened to the nuclear fuel and the chance of a future catastrophe.

Dirty Bomb? It's "In The Bag"
One of the more feared (but rather misunderstood) new terrorist weapons is the "dirty bomb," a conventional explosive surrounded by pieces of radioactive material such as medical waste or spent nuclear fuel instead of ordinary shrapnel. While fatalities from the actual explosion would be relatively limited, the amount of contamination produced by even a small bomb could be considerable - entire city blocks could be rendered off-limits because of hazardous fallout, The Nuclear Regulatory Commission calls dirty bombs "weapons of mass disruption" rather than "weapons of mass destruction" - they create more fear and panic than actual damage, although the financial costs of cleaning up after a dirty bomb could be enormous.
A Canadian company, Vanguard Response Systems, has developed a unique containment system that can be deployed in the event a dirty bomb is discovered before it explodes. It uses a patented "tent" made of several layers of bullet-proof-vest type material, and a special shock-absorbing liquid foam that not only damps the blast, but binds the bomb fragments and radioactive fallout dust produced. Discovery Channel Canada [video stream] shows the containment tents in action using real radioactive material.
This sounds like an intriguing invention - but one with some real-life limitations. I'm afraid the caveat is that bomb squads have to locate the dirty bomb, evacuate the area, and assemble and fill the foam tent before the bomb explodes; very likely if and when one does go off somewhere, it may be without any warning at all. Still, it's some small comfort knowing a device like this exists. Vanguard says the tent and foam system can also be deployed using robotic methods. [via Samizdata]

Got MOX?
Shikoku Electric Co.'s Ikata No. 3 reactor is likely to become the third facility in Japan to go "pluthermal" - to use MOX, or mixed-oxide, fuel for power generation. From the Asahi Shimbun:
Shikoku Electric Power Company...Monday informed the Ehime prefectural government of its plans to burn MOX nuclear fuel there by fiscal 2010.Greenaction-Japan is a organization which opposes the use of "pluthermal" (a Japanese term combining the words "plutonium" and "thermal") power, citing increased safety concerns:
Pluthermal power is controversial because it uses plutonium-uranium mixed oxide fuel, or MOX. Under this method, plutonium extracted from spent nuclear fuel is burned in reactors originally designed for uranium fuel. Pluthermal power is key to the nation's nuclear-fuel recycling program.
Critics warn the pluthermal method carries more health and safety risks to reactors originally designed to burn only uranium fuel. Shikoku Electric Power's plan follows those of Kansai Electric Power Co. and Kyushu Electric Power Co. Kansai Electric Power got the green light from the Fukui prefectural governor in March for its plan to burn MOX at its Takahama nuclear power plant. Kyushu Electric Power in late April notified the Saga prefectural government and the town of Genkai that it plans to burn MOX as early as 2009 at one of its reactors there.
Under Shikoku Electric Power's plan, no more than 16 of the 157 uranium-fuel elements in what are called fuel bundles-groups of fuel elements burned in a reactor-will initially be replaced with MOX at the No. 3 reactor in Ikata. The number of MOX elements will eventually be increased to about one-fourth of the bundle, with the maximum set at 40.
Over the last several years the government and electric utilities have argued that the pluthermal program is a method of recycling precious resources. They claim that it is in Japan's best interest to extract the uranium and plutonium contained in spent nuclear fuel rather than directly disposing of it as some countries do. The argument used is that Japan is an energy poor country which needs to conserve uranium resources and use plutonium for energy security purposes.The NRC has a quarterly publication called the MOX: Mixed Oxide Fuels Newsletter, "published quarterly to highlight recent news and events associated with the NRC's licensing of a mixed oxide fuel fabrication facility." The lastest March 2004 issue [PDF file] among other things, talks about the
Recently promoters of the pluthermal program have begun to argue that the program is also necessary in order to reduce the amount of surplus plutonium accumulated as a result of overseas reprocessing. Since mid- 2001, the Japanese government and electric utilities have put forward yet another argument for the pluthermal program. They claim that without the pluthermal program Japanese nuclear power plants would be unable to continue to produce power...The use of MOX fuel increases the risk and severity of a nuclear accident. When using MOX fuel, the control rods' capacity to function is reduced and power output is less stable and harder to control.

The plutonium would be used to fabricate four MOX fuellead test assemblies, which would be returned to the U.S. for proposed MOX fuel qualification tests in the Catawba Nuclear Power Station. [a two-unit power plant located on Lake Wylie in York County, S.C.]MOX is (pardon the pun) a highly-charged topic in the United States as well, as the anti-mixed-oxide site Nix-MOX clearly demonstrates with its "Top 10 Reasons to Oppose the Use of MOX":
"MOX IS A BAD IDEA!! MOX infrastructure supplies all the pieces needed for making plutonium a desirable commodity, while it claims to dispose of it. MOX legitimizes the production of plutonium by foreign countries, and creates a market for something that could used in a weapon of mass destruction. Plutonium is dangerous and should be kept out of our economy and out of our commercial reactors."

Vermonters Protest Proposed 20% Yankee Nuclear "Uprating"
The embattled, aging Vermont Yankee nuclear power plant in Vernon (which recently made headlines when two highly radioactive pieces of fuel rod were reported missing) is expected to be given a 20% power boost - or "uprating."
This doesn't sit very well with many residents of this characteristically "back-to-nature" region. From today's Brattleboro [VT] Reformer:
BRATTLEBORO -- Flashing placards, more than 125 nuclear power protesters marched downtown on Saturday, calling for a cease to "uprate" proceedings and, moreover, for Vermont Yankee's closing. The group, which made its way from the Brattleboro Food Co-op to the Common, held placards saying, "Stop Vermont Yankee," "Not Another Chernobyl," and "Does Vermont Matter?" A child in a stroller had a sign which said: "Protect My Future."Another demonstration to shut down Vermont Yankee down is scheduled for May 15 in Greenfield, Mass. Demonstrators are to meet up at Greenfield Common at 11 a.m. and march through the city to Energy Park.
Doug Wight, of Shutesbury, Mass., yelled, "Not in my backyard, not in country, not in my world," as he walked toward the Common, where demonstrators listened to anti-nuclear speakers.
The event was organized by Citizen's Awareness Network in Shelburne Falls, Mass., an anti-nuclear energy activism group. The demonstration was supposed to protest the Nuclear Regulatory Commission's unwillingness to perform a comprehensive, independent assessment of the Vernon nuclear power plant before its power output is upped 20 percent. But the NRC announced last week that it would conduct an independent engineering assessment.
The 33-year-old plant is among the oldest in the United States, which leads nuclear opponents to say it cannot withstand a 20 percent power boost. Vermont Yankee officials maintain that the plant is inspected regularly by the NRC and has not had any significant problems.The missing fuel rods from Vermont Yankee are still AWOL, and the Providence Journal (registration reguired) reports officials are planning a search of waste sites in South Carolina and Washington State in an effort to track down the pieces.

Surfing the Nuclear Web: from Australia to Argonne
Looking for more radiation related sites? There's the informative and descriptively-named Radioactive Waste blog from Australia:
Atom Central is an intriguing portal with sections on the atom bomb, the Trinity site and video releases on Hiroshima and Nagasaki, American bomb tests and more.
Of special interest is the Argonne National Laboratory's engineering research website:
Being an environmental scientist of the disorganised type, and also overwhelmed by the quantity of sites of relevance to my interest in safety of radioactive waste, my hope is that this blog will bring some order to my life (this part at least)! All views & irreverent commentary expressed here are entirely my personal opinion, of course. In Australia, after cleaning up the mess at Maralinga (former UK nuclear weapons test site), we are now in process of building a national radwaste repository.Jef's Web Files has a section focusing on nuclear safety, with recent posts about the development of detectors that can "smell" nukes, and the U.S. government's recent revival of a lost Cold War art - fallout analysis.

Of special interest is the Argonne National Laboratory's engineering research website:
Argonne's rich heritage in the development of nuclear reactors began with CP-1, the world's first nuclear reactor brought to life by Enrico Fermi and his team on December 2, 1942, under the West stands at Stagg Field on the campus of the University of Chicago.You can see some of Argonne's history in video: Argonne's pioneering nuclear research is prominently featured in the documentary Atoms for Peace (1994, VHS), hosted by Bill Kurtis (whom we met as the host of the program NOVA: Back to Chernobyl). This one-hour feature details the history of the American peacetime nuclear program with its focus on energy production (and the U.S. fast-breeder reactor program, now on indefinite hiatus), as well as its linkage back to the early weapons development initiatives at Oak Ridge National Laboratory in Tennessee, Arco, Idaho (the first town to be powered by nuclear energy) and the now-defunct Hanford site power plant in Washington state. While Atoms for Peace is a bit hard to track down, you'll probably be able to find a copy at larger public libraries with video collections.
Dr. Walter H. Zinn, one of Fermi's close colleagues working on CP-1, became Argonne National Laboratory's first director in July 1946. In 1948, the United States Atomic Energy Commission (AEC) transferred the major portion of the nation's nuclear reactor development program to Argonne. Under Dr. Zinn's vision and leadership, Argonne established a vigorous and far-reaching program to develop nuclear reactors of virtually all types.
