Resurrecting Three Mile Island

When Exelon Generation shut down Three Mile Island Unit 1 in September 2019, managers were so certain that the reactor would never run again that as soon as they could, they had workers drain the oil out of both the main transformer and a spare to eliminate the chance of leaks. The company was unable to find a buyer because of the transformers’ unusual design. “We couldn’t give them away,” said Trevor Orth, the plant manager. So they scrapped them.

Now they will pay $100 million for a replacement.

The turnaround at the reactor—now called the Crane Clean Energy Center—highlights two points: how smart Congress was to step in with help to prevent premature closures with the zero-emission nuclear power production credit of 0.3 cents per kilowatt-hour (only two years too late), and how expensive it is turning out to be to change course.

The pursuit of returning two of the country’s retired nuclear plants into service is not only unusual—it is unprecedented and promises to make history.

That’s according to a piece coauthored by former assistant secretary for nuclear energy Katy Huff in the Bulletin of the Atomic Scientists regarding plans from Holtec and Constellation to restart Michigan’s Palisades plant and Pennsylvania’s Three Mile Island Unit 1, respectively.

Google and Kairos Power partner on 500 MW advanced nuclear project

October 16, 2024, 7:08AMNuclear News

Kairos Power and Google announced over the weekend a new power purchase agreement to provide the tech giant with 500 megawatts of clean energy by 2035.

Under the agreement, California-based Kairos Power will develop, construct, and operate a series of advanced reactor plants and sell energy, ancillary services, and environmental benefits to Google. Plants will be sited in “relevant service territories” to supply clean electricity to Google data centers. The first reactor is planned to be deployed by 2030 to support Google’s 24/7 carbon-free energy and net-zero goals.

Opinion: Financing the future of clean energy—Green bonds in the nuclear sector

As evidenced by the well-attended Climate Week NYC, there is a growing awareness that nuclear energy must be incorporated into national energy strategies if net-zero goals are to be achieved. In recent years, green bonds have found solid footing in the world of energy finance. These eco-friendly issuances have evolved from supporting just wind and solar projects and are increasingly being used to power much-needed growth in the civil nuclear sector. Green bonds that have been issued over the past several years in Canada, France, Finland, and the United States are now being used to support investment in nuclear projects, from breathing new life into old reactors to in certain instances supporting nuclear new build projects. However, a question remains: Can this liquidity be deployed where and when it is needed most—to support ambitious new nuclear project buildouts?

NRC reviewing 2 unplanned shutdowns at South Texas Project

September 16, 2024, 3:26PMNuclear News

The U.S. Nuclear Regulatory Commission began a special inspection last week at South Texas Project nuclear power plant into two incidents at the site, which led to separate, unplanned shutdowns of both Units 1 and 2.

  • On May 12, a transformer that supplies off-site power to the station shut down unexpectedly and took Unit 2 off line.
  • On July 24, a fire in an electrical switchyard at the site caused an unplanned shutdown of Unit 1.

On the company’s earnings call this month, Constellation CEO Joe Dominguez was asked if there is a possibility of restarting the shuttered Three Mile Island plant—as is being proposed for the Palisades nuclear plant in Michigan.

“We’re not unaware that opportunity exists for us,” Dominguez said. “We’re obviously seen what’s happened with Palisades and I think that was brilliant. Brilliant for the nation. … We are doing a good bit of thinking about a number of different opportunities, and that would probably certainly be one of those that we would think about.”
