As the United States intensifies its efforts to combat climate change and transition to a low-carbon energy future, the role of nuclear energy has never been more critical.

One key strategy in this transition is the subsequent license renewal (SLR) of our existing nuclear power plants, allowing them to operate for up to 80 years. This extension brings several significant benefits.

Continued low-carbon energy production—By extending the life of existing nuclear power plants, we ensure a steady supply of low-carbon energy, reducing our reliance on fossil fuels and helping meet our nation’s emission reduction targets. Given that nuclear power currently provides nearly 20 percent of the U.S. electricity supply and more than half of its low-carbon electricity, maintaining this capacity is vital for a sustainable energy future.

Wind and solar droughts can hit during peak grid demand—and last nearly a week

December 13, 2023, 12:05PMNuclear News

Cloud cover cuts solar generation, and on calm days wind turbines won’t spin. When cloudy and windless conditions coincide for hours or days, the result is called a compound energy drought. Pacific Northwest National Laboratory recently found that these energy droughts can last nearly a week in some parts of the country and that they overlap with periods of peak grid demand more often than would be expected by chance.

Duke seeks approval for SMRs at retiring N.C. coal plant

August 18, 2023, 7:01AMNuclear News

Duke Energy has filed an update to its 2022 state-mandated carbon-reduction plan with the public utility commissions of North and South Carolina, proposing the deployment of small modular reactors at the Belews Creek coal plant in Stokes County, N.C., which is slated for retirement next decade. A similar system would be added at a second site yet to be determined for a total of 600 MW of advanced nuclear. (Both the advanced reactor production tax credit and investment tax credit included in last year’s Inflation Reduction Act offer a 10 percent bonus for facilities sited in certain energy communities, including those with retiring coal plants.)

Illinois lawmakers approve lifting ban on nuclear plant construction

May 23, 2023, 9:30AMNuclear News

The Illinois General Assembly has given the nod to S.B. 0076, a bill that would repeal the state’s decades-old moratorium on new nuclear power plant construction.

After passing the Senate in a 39–13 vote on March 30, the legislation proceeded to the House, where it was amended and approved 84–22 on May 18, then sent back to the Senate for concurrence. Late on May 19, the Senate agreed, 36–14 (with 3 voting “present”), to the proposed amendment. The bill now moves to Gov. J. B. Pritzker’s desk for consideration.

Vistra Corporation announced yesterday that it is seeking 20-year life extensions for its Comanche Peak reactors and has submitted an application for license renewals to the Nuclear Regulatory Commission.

Operated by Vistra subsidiary Luminant and located in Glen Rose, Texas, Comanche Peak is home to two Westinghouse-supplied pressurized water reactors. The 1,218-MWe Unit 1 began commercial operation in August 1990, with the 1,207-MWe Unit 2 joining in August 1993. The original 40-year licenses for Units 1 and 2 expire in February 2030 and February 2033, respectively.

New California law could fund Diablo Canyon life extension

July 6, 2022, 6:59AMNuclear News

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.

To aid Diablo Canyon, feds propose changes to nuclear credit program

June 21, 2022, 9:30AMNuclear News

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.)

Where’s the plan?

December 17, 2021, 3:27PMNuclear NewsMatthew L. Wald
The electric power transmission grid of the U.S. consists of thousands of miles of lines operated by hundreds of companies.

To do big things, like building the interstate highway system, or going to the moon, government usually has a plan. Electric companies and grid operators, which are responsible for keeping the lights on, always have a plan. But something unusual has happened in the past few months. About four dozen U.S. utilities, plus the federal government and many states, have promised to do something extremely big: to eliminate carbon dioxide emissions, or cut them drastically. But they are not clear on how.

The American Nuclear Society supports keeping Diablo Canyon open

The American Nuclear Society supports the continued operation of California's Diablo Canyon nuclear power plant. The premature shutdown of Diablo Canyon units 1 and 2, slated respectively in November 2024 and August 2025, will inflict grave harm to California's economy and environment.

Diablo Canyon report takeaways: California has options, and it’s time for debate

November 10, 2021, 12:02PMNuclear News

A new study by researchers from Stanford University and the Massachusetts Institute of Technology—An Assessment of the Diablo Canyon Nuclear Plant for Zero-Carbon Electricity, Desalination, and Hydrogen Production—makes a compelling case that the 2018 decision to shut down California’s only operating nuclear power plants needs another look—and that revenue options could make reversing the decision not just feasible but economically attractive.

“Fast-forward three years and things have changed,” said Jacopo Buongiorno, a professor of nuclear science and engineering at MIT and one of the authors of the report, during a November 8 webinar. Since the decision was made to shut down Diablo Canyon’s twin pressurized water reactors in 2024 and 2025 when their current licenses expire, the state has passed bills calling for net zero carbon emissions by 2045 and for restrictions on land use that could effectively limit solar installation sprawl. Californian’s have also experienced repeated grid reliability issues and prolonged drought conditions.

Australia has invested in batteries for grid security. It’s not going as planned.

Australia’s two large lithium-ion storage batteries are getting attention for all the wrong reasons. Hornsdale Power Reserve, a 150-MW battery collocated with a wind farm in South Australia, is being charged in federal court with failing to deliver on promises to respond to grid demands, and of being technically unable to deliver under the terms it was being paid to meet. Proceedings were filed September 22, just before the testing of a second Tesla-manufactured “Big Battery resumed after a two-month delay following a fire in July.

Germany: Coal tops wind energy in 2021, but there’s more to the story

September 23, 2021, 7:02AMANS Nuclear Cafe

Coal-fired plants fed the most power to Germany's electricity grid in the first half of 2021, while wind power dropped to its lowest level since 2018. As a September 13 article published on the German news site DW.com explained, the situation was blamed in part on a wind energy shortfall that is causing power price spikes across Europe.

Motivated by February’s Texas grid debacle and last month’s Electric Reliability Council of Texas (ERCOT) alert pleading with residents to conserve energy, Gov. Greg Abbott earlier this week issued a letter to members of the Public Utility Commission of Texas (PUC), directing them to take immediate action to improve electric reliability across the state. According to the governor’s office, the directives build on reforms passed in the 87th legislative session to increase power generation capacity and ensure the reliability of the Texas power grid.

An open letter to Secretary Granholm

Craig Piercy

Madam Secretary:

Congratulations on becoming America’s 16th secretary of energy! Welcome to one of the most misunderstood, confounding, yet important and underappreciated agencies in the federal government.

Even the name—the U.S. Department of Energy—is misleading. Given that the majority of its funding and operational focus is dedicated in some form or another to the splitting and fusing of atoms, the DOE should probably be called the Department of Nuclear Technology and Other Energy and Science Stuff.

Rep. Dan Crenshaw writes op-ed for The Hill in support of nuclear

Crenshaw

In an opinion piece published last Friday in The Hill, Rep. Dan Crenshaw (R., Texas) says that the Biden administration should focus on nuclear power in order to provide clean and reliable power to the grid. Speaking from the recent experience of dealing with the polar vortex that greatly affected the Texas electric grid, Crenshaw said, “People all over the world are . . . demanding cleaner energy that reduces carbon emissions. The Biden administration believes we can do this by prioritizing solar and wind energy. They’re wrong.”

Crenshaw continued, “If the Texas grid was solely or even mostly reliant on renewables last month, our situation would be far more dire. So how do we achieve both a massive reduction in emissions while also maintaining reliable baseload energy? Nuclear.”
