2012-09-15 POSITION ON SEISMIC TESTING
September 15, 2012
San Luis Obispo Mothers for Peace supports gathering seismic information about the earthquake faults near Diablo Canyon Nuclear Power Plant. In the wake of the Fukushima disaster and PG&E's application to renew the licenses, seismic studies must be done to learn more about the potential dangers posed by earthquake faults to the two nuclear reactors and the tremendous amount of high-level radioactive waste that has accumulated on site over the past 28 years.
The current proposed plans for seismic studies offshore and near Diablo Canyon Nuclear Power Plant were set in motion by AB 1632, an act of the California State Legislature. AB1632 is being implemented by the California Public Utilities Commission. At present, Pacific Gas & Electric Company (PG&E) plans to conduct these studies from November - December 2012, with the possibility of the tests being divided into two parts in successive years at the recommendation of the California State Lands Commission. Mothers for Peace asserts that there are additional faults that also need further study in order to determine whether they might lead to more severe consequences than either the Hosgri or Shoreline Fault. These faults include the Diablo Cove Fault, which runs directly under the Unit 1 reactor, the San Luis Bay Fault, and the Los Osos Fault.
San Luis Obispo Mothers for Peace shares the concerns of many local citizens and organizations about the extensive harm that will be inflicted on marine life if these studies are carried out as currently designed. PG&E’s plans rely largely on extremely loud underwater air guns, which are acknowledged by all parties to be highly disruptive to the ocean environment. Mothers for Peace urges extreme caution in the method used to obtain data about the faults in the 530 square nautical miles of the proposed testing area.
Because of grave and valid concerns voiced by the fishing and environmental communities, Mothers for Peace advocates that the seismic testing be delayed to allow time to thoroughly explore other technologies less harmful to marine life, and baseline studies of marine life must be completed and analyzed before any testing begins.
Because there is no plan for storing the radioactive wastes for the 250,000 years they will remain lethal; because Homeland Security classifies all nuclear facilities as targets of terrorism; and because of the 13 earthquake faults in the area around Diablo Canyon, San Luis Obispo Mothers for Peace for decades has recommended that the plant be shut down and all stored radioactive waste transferred to hardened casks as soon as possible.
