The Deeper Dig: A plan for what’s left of Vermont Yankee nuclear power plant

Vermont’s only nuclear plant is about two years away from being fully decommissioned.

For decades, Vermont Yankee, a nuclear power plant in Vernon, was the largest producer of electricity for the state.

The plant has been shut down since 2014, and the company that now owns it is in the process of deconstructing it. That company, NorthStar, has recently submitted a plan that describes in detail the final steps of decommissioning, which is projected to be completed ahead of schedule, by 2026.

However, national developments mean that radioactive spent fuel on the site is likely to stay where it is for the foreseeable future.

Host Sam Gale Rosen spoke to VTDigger environmental reporter Emma Cotton, who has been covering the decommissioning process.

Emma:………………………………………………………………………………………………………………………………………… In 2010, Vermont lawmakers voted in favor of denying that 20-year license renewal. They had safety concerns, particularly after the plant had a tritium leak, which is a radioactive substance. That decision became the subject of a federal lawsuit about whether the state or the feds had authority over the plant. But soon enough, that issue was of little consequence. In 2013, citing the economic environment, Entergy announced that it plans to shut Vermont Yankee down

It officially disconnected from the grid and shut down on Dec. 29, 2014. And then the private company NorthStar — which decommissions nuclear plants and other energy facilities like coal plants around the country — they bought Vermont Yankee in 2019, and they are using funds set aside by Entergy to complete this decommissioning work…………………

 Vermont’s only nuclear plant is about two years away from being fully decommissioned, at which point the site will look a lot like an open lot, with the exception of 58 spent fuel casks, which will remain there, likely, for a long time……………………………………………………………………………………….

Sam: So they’re on track to have the facility disassembled before 2026. But the other thing you’ve been covering is what happens to the spent fuel, right?

Emma: Yeah, this is kind of the elephant in the room, I think, for Vernon, the town where this is located. So after the fuel rods were used to heat water, they were transferred to cooling towers, and the process of cooling brought their radioactivity down. For a long time nuclear plants around the country were designed to temporarily store spent fuel this way, in cooling pools, and then they would be transferred to one or more federally designated areas for permanent storage.

But the federal government has not found a permanent place to store spent fuel. There has been a lot of conversation about a site in Nevada — Yucca Mountain — but there has been strong local opposition to storing the entire country’s nuclear waste there.

So nuclear plant owners had to find another storage solution. And so they started storing spent fuel in what are called dry casks, which are metal or concrete cylinders that form shells outside of the fuel rods. And according to the NRC, that shell shields people pretty effectively from this highly radioactive spent fuel. So Entergy transferred all of their spent fuel into dry casks, and now there are 58 of those that remain on the site. It’s a 2-acre part of the parcel.

NorthStar does ship some radioactive material to a facility in Texas, but it doesn’t have anywhere to send its spent fuel. So according to Northstar CEO, Scott State, the fuel will remain there until the feds come up with another plan. And that could be a while. So NorthStar will own the spent fuel until it’s removed from the property…………………………………………………………………………………………………………………………………………………….  https://vtdigger.org/2023/11/20/the-deeper-dig-a-plan-for-whats-left-of-vermont-yankee-nuclear-power-plant
