Chernobyl Database: A New, Useful Research Tool

While having much of the Internet at one's disposal through search engines is a wonderful thing - especially when you know what you're looking for - specialized blogs like the new Chernobyl Database (launched February 2013) also serve a vital purpose: they can help point you in the direction of new research studies and findings you may have been unaware of.

Chernobyl Database, which I believe is based in Japan, focuses fairly narrowly on posting papers studying the effects of radiation and radioactive contamination on the environment and health, but it also ventures deeply by including links to research going back several decades. Entries are primarily in English, with separate categories for articles published in Japanese and Russian. I think you'll find it a valuable resource.

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.



This video (:35) shows a time-lapse version of the first NSC section's raising.

Atomic Age II Fukushima Symposium, May 5th, 2012

RadioActive! readers near Chicago: the University of Chicago, the birthplace of the first controlled nuclear chain reaction, hosts Atomic Age Symposium II - Fukushima, this Saturday, May 5th.
[K]eynote speakers are Hiroaki Koide of the Kyoto University Reactor Research Institute, who has been speaking out against nuclear power for over 40 years; and Ruiko Muto, an anti-nuclear activist based in Fukushima and a member of a citizens’ group, Hairo [Reactor Decommission] Action Fukushima. Robert Rosner, Astronomy & Astrophysics & Physics, University of Chicago (former Director of the Argonne National Laboratory) will share his stance on nuclear energy via a videotaped message. Ruiko Muto’s speech will be followed by Bobbie Paul, Executive Director of Georgia WAND—Women’s Action for New Directions, Jeffrey Patterson (MD, Board Member and Past President of Physicians for Social Responsibility), and Dean Wilkie, a retired nuclear plant operator and manager who, with Nancy Foust, an online media expert, has collaborated on the Simply Info website to provide detailed information about Fukushima.
This will be an all-day symposium investigating the multiple dimensions of the ongoing Fukushima nuclear disaster through discussion by experts from Japan and the US, Saturday, May 5, 2012: 8:45am–6:00pm. This event is free and open to the public. Continental breakfast and lunch will be provided. For full information and details, visit http://lucian.uchicago.edu/blogs/atomicage/aboutsymposium/ or call 773-702-8647.

Chernobyl News: Resettlement, More Tourism, and Removal of Nuclear Fuel from Closed Reactor Units

Crews have begun dismantling the remaining nuclear fuel stockpile from the closed reactors at Chernobyl, including the only recently-decommissioned Reactor 3 (the unit involved in the 1986 explosion was Reactor 4). From the Seattle Post-Intelligencer, via AP:
KIEV, Ukraine -- Experts have begun unloading radioactive fuel from one of the closed reactors at Ukraine's Chernobyl nuclear power plant, the plant said Tuesday.

Reactor No 3. - the last to continue operating - was closed for good in 2000, but it was never emptied of fuel. The remaining fuel in reactor No. 3 and reactor No. 1 made it impossible to start construction of a new shelter over the fourth reactor, destroyed in the 1986 explosion and fire that spewed radiation over much of northern Europe.

In an effort to prevent further radiation release, engineers hastily erected a concrete-and-steel shelter over the damaged reactor, but parts of it are crumbling, and a new shelter is needed. Originally officials had planned to unload the remaining fuel into a new storage depot, but plans for its construction were suspended until 2010. The plant's spokesman, speaking on customary condition of anonymity, said the fuel will instead be unloaded into a Soviet-era used fuel depot. Unloading the fuel, which began Monday, is necessary to make the plant entirely inoperative, Chernobyl staff said.
In other Chernobyl news, Pravda reports the Ukraine is seeking to boost national revenue by offering more tours of the ravaged Exclusion Zone to foreign travelers, and RIA Novosti News says Ukrainian president Viktor Yushchenko has instructed Kiev officials to begin legalizing the homes of squatters who have moved in the area without permission.

Illinois: "Nuclear America"?

With half the state's electricity generated at nuclear power plants, Illinois qualifies as "highly dependent" on this form of energy; and with 11 currently operating commercial reactors, it's tied in first place with Pennsylvania for the "Most Nuclear Plants." Not on the list? The now-decommissioned Zion 1 and 2 Nuclear Plant near Gurnee, IL, or the decommissioned Dresden 1 plant in Morris. from the NRC's Decommissioned Plants Section:
Zion Units 1 and 2 were permanently shut down on February 13, 1998. The fuel was transferred to the spent fuel pool, and the owner submitted the certification of fuel transfer on March 9, 1998. A public meeting was held on June 1, 1998, to inform the public of the shutdown plans. The owner has converted the turbine-generators into synchronous condensers and have isolated the spent fuel pool within a fuel building "nuclear island." The plant has been placed in SAFSTOR, where it will remain until about 2013 when the decommissioning trust fund will be sufficient to conduct DECON activities. The owner will retain the spent fuel until it is accepted by the Department of Energy. The owner submitted the post-shutdown decommissioning activities report (PSDAR), site-specific cost estimate, and fuel management plan on February 14, 2000. A public meeting to discuss the PSDAR was held on April 26, 2000.
Zion may be out of service, but the Village of Gurnee maintains a webpage detailing the emergency evacuation procedure in event of an accident at the plant.
