A California court has dismissed a lawsuit brought in April by Friends of the Earth (FOE), an inveterate enemy of nuclear power, to derail last year’s state-supported plan to keep the two-unit Diablo Canyon plant running past 2025.

The California Public Utilities Commission (CPUC) has voted to open a rulemaking to consider extending the lifetime of the 2,289-MW two-unit Diablo Canyon nuclear power plant. The plant, which turns 50 this year, is the only remaining operational nuclear power facility in California. It generates nearly 10 percent of the state’s electricity needs.

Pacific Gas & Electric’s two-unit Diablo Canyon plant—California’s lone operating nuclear power facility—has been deemed eligible for the initial round of funding from the Civil Nuclear Credit (CNC) Program, the Department of Energy announced yesterday.

The decision was welcomed by a nuclear community disappointed by last Friday’s news that the DOE had rejected Holtec International’s CNC application for the recently closed Palisades nuclear plant in Michigan, despite support for the effort from Gov. Gretchen Whitmer.

Pacific Gas and Electric Company filed a letter with the Nuclear Regulatory Commission yesterday, officially requesting that the agency resume its review of the utility’s license renewal application for Diablo Canyon Units 1 and 2.

The reports of the death of the Diablo Canyon nuclear power plant may be greatly exaggerated. While Pacific Gas and Electric (PG&E) announced as early as 2016 that it would be closing California’s last operating nuclear power plant at the end of its current operating license, there has been growing political pressure to keep the plant, and its 2,200 MWe of carbon-free energy, running.

Bowing at last to the unflagging efforts of nuclear advocates over the past few years—as well as to more recent pressure from a former nuclear opponent, Gov. Gavin Newsom—the California legislature late last night approved S.B. 846, a measure that provides the option of extending operations at the Diablo Canyon nuclear power plant for five years beyond its scheduled 2025 closure date.

Pacific Gas and Electric, Diablo Canyon’s owner and operator, had agreed in June 2016 to an early shuttering of the facility, following discussions with organized labor and environmental organizations. PG&E’s application to close the plant was approved by the California Public Utilities Commission in January 2018.

The bill passed easily through both legislative chambers: 67–3 in the General Assembly and 31–1 in the Senate.

LA GRANGE PARK, ILLINOIS – Statement from American Nuclear Society (ANS) President Steven Arndt and ANS CEO/Executive Director Craig Piercy on passage of California Senate Bill 846:

A bill to extend operations at California’s Diablo Canyon nuclear plant beyond 2025 debuted last evening in the California legislature. Lawmakers have until Wednesday—the end of the current legislative session—to vote on the measure.

Coauthored by State Sen. Bill Dodd (D., Napa) and Assemblymember Jordan Cunningham (R., San Luis Obispo), Senate Bill 846 includes a $1.4 billion forgivable loan to Pacific Gas and Electric (PG&E), the plant’s owner and operator, matching the amount in the August 12 proposal from Calif. Gov. Gavin Newsom. Instead of Newsom’s proposed option for a 10-year life extension for the facility, however, SB 846 would keep the plant running for an additional five years only.

The state of California recently and quite sensibly cracked the door back open for continued operation of the Diablo Canyon nuclear power plant past the current operating license expiration dates in 2024 (Unit 1) and 2025 (Unit 2). The nonprofit North American Electric Reliability Corporation’s recently released 2022 Summer Reliability Assessment highlights the risk of electricity shortages in California. Given that concern, as well as the benefits of continued Diablo Canyon operation—including much needed clean, reliable energy; good jobs; and potential for large-scale production of fresh water—another look at the shutdown decision made several years ago is clearly warranted. Sen. Dianne Feinstein (D., Calif.) reinforced this point when she added her voice to the growing chorus of policymakers advocating extended operation for Diablo Canyon.

The decision by the Department of Energy to revise its Civil Nuclear Credit Program—easing the path toward program qualification for California’s Diablo Canyon—was not the only promising news last week for advocates of the state’s sole operating nuclear power facility. On June 30, California Gov. Gavin Newsom signed legislation that could provide funding for Diablo Canyon in the event the state decides to keep the plant in operation beyond its slated 2025 closure date. Also in line for possible life extension under the measure are some of Southern California’s fossil fuel plants.

The Department of Energy yesterday announced that it has amended its Civil Nuclear Credit (CNC) Program guidance for the currently open award cycle and extended the deadline for credit applications from July 5 to September 6. The DOE was instructed to establish the $6 billion program by the Infrastructure Investment and Jobs Act, signed into law by President Biden last November.

The Department of Energy has issued a proposed guidance amendment for its $6 billion Civil Nuclear Credit (CNC) Program in response to a letter last month from California Gov. Gavin Newsom’s administration suggesting “a few minor adjustments” to the program’s guidance to address “the unique circumstances” of the Diablo Canyon nuclear plant. (Previously a supporter of the premature 2025 closure of the Avila Beach, Calif., facility, Newsom told the Los Angeles Times in late April that his office would look into using the CNC Program to keep the plant in operation beyond its scheduled closure date, citing climate change and the threat of power shortages in the state.)

Feinstein

Although previously a supporter of Diablo Canyon’s early closure, California Sen. Dianne Feinstein took to the pages of the Sacramento Bee yesterday to endorse life extension for the state’s sole operating nuclear power plant.

Citing projected electricity shortfalls in California due to the effects of climate change, Feinstein writes that “Pacific Gas and Electric Company should reconsider its decision to close Diablo Canyon by 2025. The utility should get the plant relicensed instead, retiring it once the state can replace its production with clean sources.”

The senator continues: “I remain concerned about the lack of long-term storage for spent nuclear fuel and am working to develop better solutions. But at this point, keeping Diablo Canyon open and producing carbon-free energy is more important.”

Extending the operational life of California’s Diablo Canyon nuclear power plant beyond 2025—its scheduled year of retirement—would help the state meet its climate goals more quickly, more reliably, and more cheaply than allowing the facility to close, a new study has found.

According to Retaining Diablo Canyon: Economic, Carbon, and Reliability Implications, keeping the plant on line could not only substantially reduce California’s emissions, natural gas use, and electric power costs, but also help avoid blackouts.

This past April, California Gov. Gavin Newsom expressed interest in using the federal government’s new $6 billion Civil Nuclear Credit (CNC) Program to keep Pacific Gas and Electric Company’s Diablo Canyon nuclear plant in operation beyond its scheduled 2025 closure date.

That interest would appear not to have waned, as Newsom’s cabinet secretary, Ana Matosantos, recently sent a three-page letter to energy secretary Jennifer Granholm requesting some alterations to the program’s language to ensure that Diablo Canyon would be eligible to participate.

The full letter, detailing the requested changes, is available here.

California Gov. Gavin Newsom told the Los Angeles Times editorial board last week that his administration would look into using the federal government’s Civil Nuclear Credit Program to keep Pacific Gas and Electric Company’s Diablo Canyon nuclear plant in operation beyond its scheduled 2025 closure date.

“The requirement is by May 19 to submit an application, or you miss the opportunity to draw down any federal funds if you want to extend the life of that plant,” Newsom told the board, according to an April 29 LA Times piece. “We would be remiss not to put that on the table as an option.”

Statement from American Nuclear Society President Steven Nesbit and Executive Director and CEO Craig Piercy:

In the spirit of the letter sent earlier this month to California Gov. Gavin Newsom urging the continued operation of Diablo Canyon beyond 2025, the Climate Coalition—a pronuclear group based in Menlo Park, Calif.—has drafted a similar letter to state officials in Michigan concerning the Palisades nuclear power plant.

The letter, which at this writing has over 260 signatories, implores Gov. Gretchen Whitmer and members of the Michigan legislature to take action to save Palisades. Owner and operator Entergy has slated the plant for permanent closure in May, nine years before the expiration of its operating license.

The San Luis Obispo County Board of Supervisors earlier this week endorsed extending the life of Diablo Canyon—California’s last operating nuclear power facility—which owner and operator Pacific Gas and Electric Company has scheduled for permanent closure in 2025. The two-unit, 2,289-MWe plant is located in San Luis Obispo County, near Avila Beach.

Seventy-nine scientific and business luminaries, including a number of the world’s leading experts on climate and energy, have signed a letter imploring California Gov. Gavin Newsom to postpone the premature retirement of the Diablo Canyon nuclear power plant, currently slated for closure in 2025.
