Notice of Initial Commission Workshop on the AB 1632 Nuclear Power Plant Assessment

In the Matter of:

AB 1632 Nuclear Power Plant Assessment

Docket No. 07-AB-1632



Notice of Commission Workshop on the
AB 1632 Nuclear Power Plant Assessment

The California Energy Commission (Energy Commission) will conduct a public workshop to review the draft study plan for the Nuclear Power Plant Assessment required by Assembly Bill 1632 (Blakeslee, Chapter 722, Statutes of 2006). AB 1632 requires the Energy Commission to complete an assessment, using existing scientific studies, of the vulnerabilities of these plants to a major disruption due to a seismic event or plant aging, to assess the potential impacts of such a disruption and the costs and impacts from nuclear waste accumulating at the state's operating nuclear plants, and to evaluate other key policy and planning issues regarding the future role of California's existing nuclear plants in the state's energy portfolio. Public input provided at the workshop or in writing will be considered in finalizing the study plan for the AB 1632 Assessment.

The workshop will be held on:

Starting at 9 a.m.
1516 Ninth Street
First Floor, Hearing Room A
Sacramento, California

(Wheelchair Accessible)

Audio from this hearing will be broadcast over the Internet.

Passcode: [AB 1632] Call Leader: [Barbara Byron]


California's two operating nuclear power plants, Diablo Canyon and the San Onofre Nuclear Generating Station (SONGS), contribute a significant portion of California's electricity supply. These plants are located in seismically active zones along California's central and southern coast. In addition, they generate spent nuclear fuel, which will be stored at the plants indefinitely until the federal government develops a permanent means for nuclear waste disposal.

AB 1632 directs the Energy Commission to complete an assessment, based on existing scientific studies, of the vulnerabilities of these plants to a major electrical supply disruption caused by a major seismic event or plant aging, the potential impacts of such a disruption, the costs and impacts from waste accumulating at these plants, and other major issues related to the future role of these plants in the state's electricity supply system.

The draft study plan for the AB 1632 Assessment will be posted on the Energy Commission's website [] and presented at the workshop.


Since the 1970s, the debate over the future of nuclear power in California has focused on concerns about the disposal of high-level nuclear wastes (spent fuel) generated by nuclear power plants, seismic issues, safety and security risks, economic costs, and environmental impacts. The California Legislature enacted laws in 1976 requiring operational and approved high-level nuclear waste disposal and fuel reprocessing options before construction of additional nuclear plants could occur in California. The Energy Commission was charged with evaluating those options and ultimately concluded that no operational and approved federal waste disposal or fuel reprocessing options existed. This finding was reaffirmed in 2005 and in 2007 in the Energy Commission's Integrated Energy Policy Reports.

California utilities are responsible for the safe storage of spent fuel from the operating nuclear plants until the federal government builds a permanent national repository for the disposal of highly radioactive wastes. In addition, California consumers have paid, since enactment of the federal Nuclear Waste Policy Act as amended in 1987, over $1.4 billion to support federal efforts to develop a program for the permanent disposal of spent nuclear fuel. Because of continued delays in the federal program for developing a national waste repository at Yucca Mountain, spent fuel must be retained indefinitely at nuclear power plant sites. Since California reactors are unable to transfer spent fuel offsite, the utilities are reconfiguring their onsite spent fuel storage pools and building onsite dry storage casks. This imposes costs and potential risks on California ratepayers.

AB 1632 requires the following analyses to be completed:

The Energy Commission must adopt the AB 1632 Assessment by November 1, 2008, and include this in the 2008 IEPR Update report. The Energy Commission must also periodically update its analysis to the extent new seismic hazard studies are issued.

Workshop Participation and Comments

The Committee is seeking the active participation of interested parties in discussing the study plan for the AB 1632 Assessment.
