"Lessons Learned from 'Lessons Learned': The Evolution of Nuclear Power Safety After Accidents and Near-Accidents" (AAAS monograph, 2012)

Continuing our theme of our evolving understanding of nuclear power safety, I'd like to highlight an excellent - and timely - paper just released by the American Academy of Arts and Sciences, "Lessons Learned from 'Lessons Learned': The Evolution of Nuclear Power Safety after Accidents and Near-Accidents," by Edward D. Blandford and Michael M. May. From the preface:
"As countries struggle to meet the electricity demands of their growing populations while also reducing their carbon footprints, many have turned to nuclear energy. The U.S. nuclear energy program may not increase significantly in the coming decades, but other countries, including many developing countries, have plans for rapid expansion. Even after the recent accident at the Fukushima Daiichi Nuclear Power Plant in Japan, the global trend toward expansion of nuclear energy has continued.

While serious accidents like Fukushima, Three Mile Island, and Chernobyl can provide invaluable lessons, the nuclear industry, nuclear regulators, and the research community must study minor incidents and near-accidents as well. These experiences often reveal not only how to decrease the likelihood that the same mistakes will occur, but also how to avoid larger accidents that may be foreshadowed in earlier, smaller incidents.

In this paper, Edward Blandford and Michael May enumerate the lessons from nuclear accidents and incidents, asking whether the nuclear energy community has indeed learned from those lessons. The authors argue that stakeholders must commit to ongoing improvement of their protocols and standards. Each nuclear incident—no matter its size—underlines the importance of pursuing high standards of safety, security, and proliferation resistance."
One standout key finding in "Lessons Learned..." is on page 23, in Table 1, "Main Sources of Electricity in the World and Their Morbidity and Greenhouse Gas Emissions Per Unit of Electricity Produced." The authors find that while nuclear energy is the fourth most prevalent form of electricity generation worldwide (at 14% of global usage), it is associated with the lowest number of deaths per terawatt hour (0.04). The least common form of generation, wind power (< 1% of global usage), somewhat surprisingly has a morbidity rate of 0.15 deaths per terawatt hour, but I suspect many of these might be a result of accidents involving installation or maintenance of the wind turbines, rather than the operating process itself.

If you're pressed for time, the paper's executive summary provides an informative primer on its conclusions and policy recommendations for the industry. The paper is available as a free PDF download as part of the AAAS' Occasional Papers series at http://www.amacad.org/publications/lessonsLearned.aspx, or as hard copy for a nominal fee from the AAAS.

Archives: [20th] Anniversary of the Chernobyl Disaster

So, my research into Chernobyl (which includes scouring the Web and government sites, and the University of Chicago and Harold Washington Libraries) has been slightly delayed. However, for the curious, I have a selection of choice hand-picked links that will provide multi-national insights into the incident, and its continuing aftermath.

BBC: Chernobyl 20 Years On

The German nuclear-safety agency GRS [Gesellschaft für Anlagen und Reaktorsicherheit, mbH] has a well-illustrated, informative 179-page free online technical report called "The Accident and the Safety of RBMK Reactors" [large PDF file, 5Mb].

If you enjoy government reports and "blue books," visit the World Nuclear Association's Chernobyl page, which includes links to UNSCEAR [United Nations Scientific Committee on the Effects of Atomic Radiation, which published several comprehensive reports on the Chernobyl disaster - many which are available here as free PDF downloads.

Watch This: Chernobyl.co.uk, a UK site which features a link to the BBC's recent 30-minute program [streaming RealPlayer video] on Chernobyl, featuring a look at the history of nuclear power in the former Soviet Union as well as a look inside Ukraine's Exclusion Zone towns. Highly recommended: this program illustrates that the deteriorating reactor site is still an issue of pressing concern through Europe, while it has been all but overshadowed here in the U.S.

Watch This: though the bulk of Chernobyl news coverage occurred before the age of streaming video, the post-date digitized BBC retrospective of the Chernobyl disaster [RealPlayer required] is a wistfully immediate - if lo-res - look back at those fateful days in April 1986.

Ukrainian biker gal (and young scientist) Elena is the Kidd [sic] of Speed: her wildly popular site, Ghost Town, features dozens of startling photos and rueful, blustering commentary from her motorcycle tour through the post-apocalyptic Exclusion Zone in Pripyat': part National Geographic expedition, part Jackass-meets-Evel Knievel. Strange thing is, I'd probably do it too, given the opportunity and a lead X-ray apron - but I'd prefer an enclosed vehicle, like a Bradley.

Got Euskadi? The Basque Website of Pripyat.

Have Paris, Rome, and the Caribbean lost their appeal? Been there, done that? How about a guided group tour through Chernobyl? I don't know if it's a legitimate enterprise, but you can apparently book a tour through the Exclusion Zone via Ukrainian Web Chyornobyl' Tour. You get complimentary disposable outerwear and shoes, and a souvenir computerized dosimeter printout that certifies how much radiation you absorbed during your visit.

Gla55pak.com has compiled some unusual Chernobyl images here, and proclaims "I have a sick curiosity - more of an impulse - to be there that night and watch the thing light up. I would gladly take a good dose just to have seen it. It is, after all, like an immense train wreck that I just can't help but see." Also: link to Disenchanted.com's take on the Chernobyl and TMI incidents, called "Fear's just bad for business".

Nuclear TV: PBS' Look Back at TMI, NOVA's Back to Chernobyl

(UPDATE 6/14/12: While "Meltdown at Three Mile Island" and "Back to Chernobyl" are not to my knowledge available on PBS' website, or through services like Netflix (unlike many other titles in the excellent American Experience series), with a little searching you should have little trouble finding them on YouTube in most countries.)

While you won't find many nuclear-energy related videos at your local video store (documentaries, anyway) there are some noteworthy releases available at libraries and at retail - mostly from transcription dealers and "deep-catalog" mail order outlets like Amazon.com. Being fortunate enough to have access to resources like the University of Chicago and Harold Washington libraries, I tracked down some excellent programs I'd like to recommend: but I should mention that none of the titles here are available in DVD format at this point, only as VHS tapes.

PBS' The American Experience: Meltdown at Three Mile Island (60 min.) replays the events of America's worst nuclear accident in 1979. With vintage news footage and contemporary interviews with key response team players like former Pennsylvania governor Dick Thornburgh and Attorney Governor William Scranton, this documentary is an exceptional inside look back at those panicked days near Harrisburg. This was a personally fascinating retrospective for me; not only for the content, but because I was living in Central New Jersey - less than two hours away by car from Three Mile Island - at the time of the accident.

As you watch the events unfold, what comes to mind is how unnecessary much of the TMI media confusion was in retrospect, although it may have been unavoidable at the time. For hours on end, emergency responders and the PA governor's office were unable to reach the power plant's operators, because the ordinary landlines were jammed tight with reporters' calls from around the country. No "Red Phone" hot-line was active, no two-way radio, and of course, no cell phones: the stricken plant was essentially incommunicado during some of the most crucial hours.

NOVA: Back to Chernobyl (originally aired February 14th, 1989) is an out-of-print title, but well worth tracking down, and you may likely find a copy at a library near you. Correspondent Bill Kurtis travels to the Soviet Union for a visit to the reactor site three years after the incident, and speaks with a number of survivors and eyewitnesses. Darkly humorous are the scenes with Kurtis' chatty ushanka-capped [уша́нка], Geiger counter-toting liason, Dr. Richard Wilson, who tries to reassure the journalist that the rather alarming radiation readings are nothing to worry about:
Kurtis: "Professor, how far do you think we are now from the reactor?"
Wilson: "Oh, about 30 miles."
Kurtis: "Should we check the readings?"
Wilson: "You’ll hear a high-pitched whistle as it checks the battery first. You’ll begin to hear some clicking as the readings start coming in. That’s a pretty good background, about the same as it was in Kiev. Let me just check the instrument. I’ll pull a source out of my case here."
Kurtis: "That level would seem to be the natural background."
Wilson: "That’s the natural background, but now you can test the beta ray [remember these are really particles] source, and you can hear it clicking furiously."
Kurtis: "What will the level be around the reactor itself?"
Wilson: "On this scale, around the reactor itself, we’ll find the reading to be off-scale, and we’ll have to change to the next scale. It’s about 30 times the background level around the reactor itself."
Kurtis: "Will that be any danger to us?"
Wilson: "No, you can be there for a year and get the amount of radiation that a worker is allowed to have in a year."
