Catastrophic Risks of GE BWR Mark I High-Level Radioactive Waste Storage Pools

Beyond Nuclear has published a new backgrounder, "Catastrophic Risks of GE BWR Mark I High-Level Radioactive Waste Storage Pools."

Worker falls in "radioactive waste pool" at San Onofre

The North County Times reports that yet another incident has occurred at the problem-plagued San Onofre nuclear power plant. A worker lost his balance and fell into the radioactive waste pool. However, the exact type of pool he fell into is not entirely clear. Was it the high-level radioactive waste storage pool? Was it the reactor cavity, after irradiated nuclear fuel (now high-level radioactive waste) had been removed from the core and transferred into the high-level radioactive waste storage pool? Also, exactly what tests were performed on the worker? Were appropriate tests done to confirm the presence of internal radioactive contamination, or not?

A similar incident occurred many years ago at the high-level radioactive waste storage pool at the University of Michigan's research reactor in Ann Arbor. And, as documented in Dave Lochbaum's book Fission Stories, a scuba diver sent into the Calvert Cliffs nuclear power plant's high-level radioactive waste storage pool to make repairs accidentally swam too close to irradiated fuel, exposing his hand to a very high dose of hazardous gamma radiation.

North Anna's twin reactors and radioactive waste storage experience another earthquake

NRC file photo of North Anna nuclear power plant, located on the shore of Lake Anna, VAAs reported by a Dominion Nuclear "Notification of Unusual Event," the twin atomic reactors at North Anna nuclear power plant in Mineral, Virginia experienced a 3.2 magntiude earthquake yesterday. Dominion claims no damage was done, and both reactors remain at 100% power. The timing of the earthquake is ironic. Today, NRC announced a new model for determining seismic risks at atomic reactors in the central and eastern U.S. And on Feb. 2nd, an NRC Petition Review Board will hold a second meeting with Beyond Nuclear and environmental allies, regarding an emergency enforcement petition to shut down both North Anna atomic reactors until adequate seismic protections are put in place. A 5.8 magnitude quake, epi-centered just 11 miles from North Anna, damaged high-level radioactive waste storage casks on August 23, 2011.

Beyond Nuclear expert witness testimony before Canadian Nuclear Safety Commission

In October 2011, Beyond Nuclear's Kevin Kamps was honored to be asked by Families Against Radiation Exposure in Port Hope, Ontario, Canada to serve as its expert witness in a proceeding before the Canadian Nuclear Safety Commission regarding Cameco's application for a five year license extension at its Uranium Conversion Facility, just off downtown and very near residential neighborhoods. Cameco's waterfront facility is amongst the oldest nuclear industrial sites in the world, first opened in 1932 as a radium extraction plant. Port Hope's residents have suffered many decades of radioactive pollution and contamination as a consequence.

Kevin submitted his written comments to CNSC on December 19, 2011. He focused on the radioactive stigma impacts to Port Hope, including on property values, as well as threats of flooding at the site due to climate destabilization, as well as security risks given Cameco's (and its predecessor Eldorado's) involvement in the nuclear weapons industry, as well as depleted uranium (DU) munitions. Kevin then attended a three day long hearing before the CNSC, from January 17 to 19, 2012, at which he testified.

In late March, 2011 Kevin also served on the Northwatch team, along with Northwatch's Brennain Lloyd and Great Lakes United's John Jackson, at a Joint Panel Review concerning proposed new reactors at the Darlington Nuclear Power Plant, just a short distance west of Port Hope. Kevin focused on high-level radioactive waste risks associated with that proposal. A coalition of environmental groups in Ontario has since filed a lawsuit challenging the decision to move ahead with those new reactors.

The radioactive waste at "The Fourth Reactor and the Destiny of Japan"

In an essay by that title, Akio Matsumura has warned about the risks of Fukushima Daiichi Unit 4's high-level radioactive waste storage pool collapsing:

"In the last weeks, I have been speaking constantly with Japanese government and party leaders on this urgent issue. Surprisingly, most of them were not aware of the dangerous situation. I, along with many eminent scientists, are emphasizing the precarious situation of the fourth reactor that contains 1,535 nuclear fuel rods in the pool and is balanced on the second floor [sic*], outside of the reactor containment vessel. If the fuel rods spill onto the ground, disaster will ensue and force Tokyo and Yokohama to close, creating a gigantic evacuation zone. All scientists I have talked with say that if the structure collapses we will be in a situation well beyond where science has ever gone. The destiny of Japan will be changed and the disaster will certainly compromise the security of neighboring countries and the rest of the world in terms of health, migration and geopolitics.  The Japanese government should immediately create an independent assessment team to determine the structural integrity of the spent fuel pool and its supporting structure. This is of the highest importance: the structure’s security is critical to the country’s future."

Dr. Gordon Edwards, Montreal based President of the Canadian Coalition for Nuclear Responsibility (CCNR), whole heartedly agrees with Matsumura about these risks. Edwards has provided a technical backgrounder about the risks, and has called for international assistance to prevent a worsening of the Fukushima Nuclear Catastrophe that could result from a collapse of the storage pool, and the ignition of overheated irradiated nuclear fuel. Edwards provided Matsumura more technical detail in a letter on January 13th.
