Public Utility Commission review of proposals for new storage facilities for spent nuclear fuel (a) Neither the owners of Vermont Yankee nor their successors and assigns shall commence construction or establishment of any new storage facility for spent nuclear fuel before receiving a certificate of public good from the Public Utility Commission.

Vermont Yankee nuclear power plant license renewal application fails to satisfy U. Nuclear Regulatory Commission ("NRC") regulations or the National Environmental Policy Act ("NEPA") because it does not address the environmental impacts of spent fuel pool accidents, including accidents caused by intentional and malicious acts.

We are. While waiting on regulatory approvals for the sale, Entergy has moved ahead with a million project to transfer all of Vermont Yankees spent fuel out of a cooling pool. Crews move the 58th and final spent fuel storage cask at Vermont Yankee earlier this summer.

Entergy submitted photo F ederal regulators have issued a final seal of approval for Vermont Yankee. VERNON, Vt. - Vermont Yankee has finished moving its highly radioactive fuel from the spent fuel pool in the reactor building of the shuttered plant, its Estimated Reading Time: 3 mins.

Now, even though Vermont Yankee is closing, and will stop generating spent fuel by years end, theres a lot stored in its spent fuel pools that will eventually have to take the next step.

The NRC regulates safety at nuclear plants. Hopefully, Vermont does not plan to spend more money trying to regulate nuclear safety and then losing court cases.

If the legislature was trying to figure out how to tax Vermont Yankee, it seems they need a tax expert, not someone who would tell them scary things about radiation in the spent fuel pool.

Today, in the second of three parts about closing Vermont Yankee, NEI looks at the looming energy shortages in the far Northeast. Along with Vermont Yankee, nearly 1, megawatts of baseload electric generating capacity will retire in New England this year, including a megawatt coal- and petroleum-fired power plant in Massachusetts.

The solid ceramic fuel pellets in the fuel bundles that have been removed from the reactor as spent fuel and stored in dry casks are air cooled by natural circulation through the cask.

The pellets have been stored in water for more than five years and are generating very little heat. Spent-fuel pools need electricity to pump water to cool the fuel rods, as well as to maintain a high water level to prevent radiation from escaping. At present, however, there is no federal requirement for back-up power supplies for spent-fuel pools, to ensure the circulation of water continues in a blackout situation, the report notes.

Between andNew England said it experienced a 15 decrease in production from non-emitting generators, largely on the loss of more than MW from Vermont Yankee.

The Vermont Yankee nuclear power plant in Vernon, Vermont is a relatively young steam plant that uses a low-cost, essentially emission-free fuel. It is strategically located in an area with few fossil fuel resources, extreme weather, and frequent spikes in electricity prices.

Thomas Gardiner The transfer of spent fuel at the shuttered Vermont Yankee nuclear plant is proceeding as planned, a manager for owner Entergy said last.

Entergy has announced that cleaning up Vermont Yankee could cost billion, and now estimates that the plant will sit idle for two decades before the process begins. The good news is that the troubled plant will not be producing more radioactive waste in the mean time, and the highly dangerous fuel rods will be removed from the storage pool.

Irradiation of staff during repairs which last a year (Nucleonics Week 31590; WISE   In another development, TEPCO is becoming sure that the spent fuel pool at No. 4 plant is leaking somewhere, since the rate at which it's adding water can't be evaporating fast enough to account for the daily level loss.

You'd have to wonder if the pool is cracked, or a spent fuel pool cooling system pipe leaking from quake hydrogen burn damage. The New York Times Matt Wald provides a nicely reported history and the state-of-play in the small reactor world.

Just as the first domestic nuclear reactors were scaled up versions of small reactors, current versions of the tiny titans are scaled down versions of full-scale reactors (actually, some of them are some are based on new ideas entirely).

The Vermont Yankee announcement means that New England ratepayers will be even more beholden to the fluctuations of the natural gas markets and the.

Washintons Blog InLeuren Moret warned in the Japan Times of the exact type of nuclear catastrophe that Japan is now experiencing: Of all the places in all the world where no one.

The Vermont Yankee plant is said to be identical in design to the Fukushima reactors. There will be a circulation of atomjacks over the next few weeks as these heroes continue to make sure that the amount of radiation emitted is minimized.

the water is flowing out of the spent fuel rod pool. The rods stand on end, 14 feet tall, with. is a platform for academics to share research papers.

In the afternoon, I worked on some leads for stories either for ANS Nuclear Cafe or for Atomic Power Review (one lead might pan out, as you will see) and attended the ANS President's Special Session entitled "Low Level Radiation and its implications for Fukushima Recovery," as well as a technical panel session entitled "Solving the Spent Fuel.

Over time, as the spent fuel is stored in the pool, it becomes cooler as the radioactivity decays away. These pools contain an enormous quantity of water-enough to cover the fuel by about 20 feet.

The water serves two purposes: it cools the fuel and shields workers at the plant from radioactivity. Issues of spent fuel pool and dry cask safety are the concerns of a specific plants relicensing process, said regulators in the latest hearings. Its like dealing with the Mad Hatter, commented Kevin Kamps, a radioactive waste specialist for industry watchdog Beyond Nuclear.

Jam yesterday, jam tomorrow, but never jam today. Natural convection moves it through. So far as I know, there are no reactors that use natural circulation in the secondary, non-radioactive water circuit.

But natural circulation is irrelevant to whether the plant can avoid meltdown. The only relevant. Maine Yankee Atomic Yankee Power Plant.

The table lists some of the organisms that live in this environment and their food sources. ALVAREZ: Typically, a spent fuel pool will contain ten to twenty times more long-lived radioactivity than the core.

The short-lived materials have decayed away and the spent fuel, of course, accumulates over time. And so its much more of a danger and hazard in terms of the materials that will stick around for quite a while.

An S PRISM related study "S-PRISM Fuel Cycle Study: Future Deployment Programs and Issues," suggested that as of the yearfour hundred tons of plutonium could be recovered from spent nuclear fuel.

This in turn would provide enough plutonium to supply start up charges for twenty-two, MWe S-PRISM facilities with ab output of 33, MWe. An article about the future of spent nuclear fuel being up in the air in The mentions a June update by PNNL's Steve Maheras to Vermont Yankee Nuclear Decommissioning Citizens Advisory Panel on the status of planning for the future of spent nuclear fuel.

Yes Vermont Yankee: The very latest lawsuit: opponents will probably lose. To keep operating, Vermont Yankee nuclear power plant needs a Certificate of Public Good from the Vermont Public Service Board (PSB).
