CEC Contingency Planning for Diablo Canyon Rochelle Becker

CEC Contingency Planning for Diablo Canyon Rochelle Becker Alliance for Nuclear Responsibility April 27, 2015

WHERE WE WERE: “In the current energy agency planning processes, there does not appear to be an overt consideration of lengthy shutdowns for the nuclear units on reliability or other implications for customers. ” California Energy Commission Nov. 20, 2008

WHERE WE ARE: “A grid reliability assessment was evaluated for the absence of DCPP. This study determined that there was no material mid- or long-term transmission system impacts associated with the absence of Diablo Canyon. ” 2012‐ 2013 Transmission Plan

WHERE WE ARE: “When San Onofre went out we were caught pretty unaware. . . The same, similar kind of thing could happen at Diablo Canyon at any point and I think we need both a short-term and a long-term plan for dealing with the eventual absence of Diablo Canyon. ” CPUC Commissioner Mike Florio April 9, 2015

CURTAIL RENEWABLE GENERATION ? “The Trajectory scenario had moderate curtailments. . . However the highest single hour curtailment reached 5, 927 MW, which is not insignificant. The curtailments in the Expanded Preferred Resources and 40% RPS in 2024 scenario were significant. . . The maximum hourly curtailments were above 14, 000 MW and 13, 000 MW respectively. ” CAISO testimony in R. 13‐ 12‐ 010 August 13, 2014

HOW WILL WE GET TO 50% ? “As shown in Table 18, the Trajectory without Diablo Canyon scenario has the least curtailment. . . ” 83% LESS CAISO testimony in R. 13‐ 12‐ 010 August 13, 2014

WHAT DOES OUR CURRENT PLAN SAY? “Energy infrastructure disruption may take the form of terrorist attacks targeting power plants, and in particular, the state’s nuclear power plants. ” State of California Energy Assurance Plan June 2014 CEC‐ 600‐ 2014‐ 006

WHAT DOES OUR CURRENT PLAN SAY? “The [NRC] struggles to balance the concerns of plant operators that additional security requirements are excessive and too costly with critics’ concerns that the same requirements are inadequate. ” State of California Energy Assurance Plan June 2014 CEC‐ 600‐ 2014‐ 006

WHAT DOES OUR CURRENT PLAN SAY? “The NRC’s process for determining which concerns need to be addressed and how they should be addressed has not always been transparent, even to governmental or quasigovernmental organizations. . . “ State of California Energy Assurance Plan June 2014 CEC‐ 600‐ 2014‐ 006

WHAT DOES OUR CURRENT PLAN SAY? “NRC has not explained why the agency is confident that the current fleet of U. S. reactors would stand up to aircraft attacks with a very low probability of radiation release, while some professional studies appear to have come to very different conclusions. ” State of California Energy Assurance Plan June 2014 CEC‐ 600‐ 2014‐ 006

MARKETS SEND PRICE SIGNALS April 18, 2014 Wall Street Journal: • Roughly half of US’s 99 reactors operate in deregulated markets. • As many as 3 dozen are at risk for economic closure. How long will regulated states passively absorb an increasingly obvious cost subsidy?

PG&E is showing the strain. • Downgraded by INPO. • Retracted its commitment to abide by California’s OTC policy – seeking exemption instead. • Rushed AB 1632 studies to NRC before receiving required review by IPRP. • Ignored shutdown order from NRC Resident Inspector for seismic design violation. • Only NRC utility licensee in U. S. history to face federal criminal prosecution.
