The Nuclear Regulatory Commission has granted Holtec Decommissioning International’s request to revise the emergency preparedness plan for the Palisades nuclear power plant in Covert, Mich., to reflect the plant’s decommissioning status.

San Onofre Nuclear Generating Station: A brief history

Ten years ago this month, on June 7, 2013, Southern California Edison (SCE) communicated the decision to permanently shutter the San Onofre Nuclear Generating Station (SONGS). The decision set in motion the decommissioning of a plant that had provided steady baseload power for the region since 1968 during a period of tremendous growth in the western United States. In the end, issues presented by the planned replacement steam generators that were intended to support future plant operations proved too large of a hurdle, and the plant was forced to retire.

What is the public perception of the U.S. electricity grid?

When my book Shorting the Grid was published in 2020, many described it as “alarmist.” Most people in the United States took grid reliability for granted. Sure, there were always power outages during storms, but weird things like “rolling blackouts” only happened in California.

Public perception is changing, however. Part of this change is due to the major February 2021 blackout in Texas, as well as the grid emergencies during December 2022. People became aware that their own grid could have problems, and not just the usual power-line-fails-in-a-snowstorm type of problems. For example, last December, the service areas for Duke Energy and the Tennessee Valley Authority in the southeastern U.S. experienced rolling blackouts. Grid operators had to take emergency measures. The Midwest, Texas, and New England experienced near misses with grid trouble. In other words, most of the country was at risk of rolling blackouts due to one relatively short winter storm.

Lightbridge Corporation, which is continuing to work closely with national laboratories on the manufacture and testing of its metallic fuel rod designs for light water reactors, just announced the results of an investigation on the casting process for molten uranium and zirconium with Pacific Northwest National Laboratory under the Department of Energy’s Gateway for Accelerated Innovation in Nuclear (GAIN) program.

OECD NEA’s workshop on reactor systems seeks participants

February 22, 2023, 7:02AMANS Nuclear Cafe

The OECD Nuclear Energy Agency is offering the first International School on Simulation of Nuclear Reactor Systems (SINUS) workshop in May this year, with the topic “Reactor Single- and Multi-Physics Simulations Based on Light Water Reactor (LWR) Uncertainty Analysis in Modeling (UAM) Benchmark.”

Registration for the workshop is available online.

The legacy of Experimental Breeder Reactor-I

On December 20, 1951, EBR-I became the first power plant to produce usable electricity through atomic fission. It powered four 200-watt light bulbs and eventually generated enough electricity to light the entire facility. (Photo: DOE)

"At 1:23 p.m. load dissipaters from the generator were connected—electricity flows from atomic energy.” These were the words Walter Zinn wrote in the log after the first four light bulbs were illuminated by nuclear energy. The year was 1951, and the EBR-­I was about to show the world what nuclear energy had to offer.

Holtec continues the decommissioning work at Indian Point nuclear power plant in Buchanan, N.Y.

Unit 2, a 1,028-MWe pressurized water reactor, was shut down in April 2020; Unit 3, a 1,041-MWe PWR, was closed one year later. (Unit 1 was decommissioned in 1974.)

NRC agrees to review SLR application for St. Lucie reactors

Florida Power and Light Company is seeking to keep its St. Lucie nuclear plant in operation into the 2060s, and so far, so good: In early August, the utility submitted to the Nuclear Regulatory Commission a subsequent license renewal application for the facility’s two units, and last Friday, the NRC accepted the application for review.

Woke nuclear?

After decades of relinquishing its value and return on investment as “emission-free” electricity generation, segments of the nuclear industry are pursuing actions in several states to secure emission credits for avoiding greenhouse gas emissions. To harmonize electricity market stability and greenhouse gas emission reduction goals, states such as New York and New Jersey have enacted programs to award zero emission credits (ZECs) to nuclear plants for their emission-free output.

Dearly earned and too long forgone, air emission credits have been the economic birthright of the nuclear industry since the passage of the 1990 Clean Air Act (CAA) amendments, when emission control capability first became a tradable commodity. Yet it took until 2016 for ratepayers and shareholders to receive even a small fraction of this valuable return on investment.

Korean team commits to R&D for marine molten salt reactors

The commercial nuclear power program in the United States was sparked by the Shippingport Atomic Power Station project-but one project does not a program make. Action by the U.S. Congress soon after the announcement of the project ensured that a wide program that would evaluate other approaches was launched:
