Heat shuts down French nuke plants: Who keeps lights on?

Comments: France, France, France, the nuclear renaissance, what about not putting all your eggs in one basket! Attention Southern Senators, who wants to build 100 new nuke plants in America because they want to be like France! Maybe not! The south is very hot, hotter than France is, our rivers are very warm, and our ocean temperatures are very warm in the summer! People of America and France, demand our leaders to use green energy and renewable energy. Uranium is not renewable and uranium mining ruins Mother Earth! NO TO NUKE POWER, NO TO URANIUM MINING!

The current heat wave is putting a strain on UK energy supplies, in part because France has had to reduce its nuclear power output, requiring it to import more of its electricity from Britain.

As reported in the Times Online, EDF has been forced to slow down many of its inland nuclear plants in France as warmer river temperatures have made it more difficult to provide adequate cooling for reactors. As a result, France has had to import as much as 1,000 megawatts of electricity from the UK at peak times to meet its own demand.

According to IT vendor F5 Networks, such circumstances are “only a taste of things to come, as temperatures continue to surge, and the global threat of climate change continues to hang over businesses.”

“The UK is keeping France running as a third of its nuclear power stations are switched off, there is already a debate around whether the UK faces a real electricity shortage in the near future,” said Owen Cole, technical director for UK&I at F5 Networks.

“Given that there is credible, independent research to suggest there is a real threat, enterprises have no choice but to incorporate this scenario into their business continuity and disaster recovery planning,” Cole said. “They cannot assume consistency of power supply. Strategic planning should incorporate a two-fold approach — working out firstly how to conserve energy, and secondly how to use energy more efficiently without affecting the business.”

He added, “Modern data centres can use the equivalent energy to small towns. Given the huge amount of power involved, heat efficient resources must be considered to allow power conservation, so if electricity supply is cut, backup generators can use this excess energy to help ensure critical operations are running. On the usage side, imperatives include reviewing options around the dynamic provisioning and de-provisioning of equipment on a per-need basis, thereby using only necessary power.

“On the national policy level, if we don’t make plans to cope with the possible restricted supply of energy, we face becoming more reliant on other countries — we might have to buy in our supply. This sort of loss of control over energy policy isn’t a favourable scenario. If the UK is helping other countries already, who’s going to be left to leave our lights on?”

UPDATE 2-Entergy shuts NY Indian Point 3 reactor

Fri May 15, 2009 10:30am EDT
(Updates with company release)

NEW YORK, May 15 (Reuters) - Entergy Corp (ETR.N: Quote, Profile, Research, Stock Buzz) manually shut the 1,025-megawatt Unit 3 at the Indian Point nuclear power station in New York from full power on May 15, the company said in a release.

The company said operators shut the plant due to a problem with a valve on the non-nuclear side of the plant that controls the flow of water into one of the unit's four steam generators. Steam generators produce the steam that spins the plant's turbines.

There was no release of radiation.

The company did not say in the report when the unit would return.

The 2,045 MW Indian Point station is located in Buchanan in Westchester County about 45 miles north of New York City. The station has two units, the 1,020 MW Unit 2 and the 1,025 MW Unit 3, which entered service in 1973 and 1976.

Unit 2 continued to operate at full power.

One MW powers about 800 homes in New York.

In April 2007, Entergy filed with the NRC for a 20-year extension of the unit's original 40-year operating licenses.

On its web site, the NRC said it will likely make a decision on the renewal sometime after February 2010 at a date still to be determined due in part to upcoming hearings concerning numerous contentions.

Community and environmental organizations have been trying to shut Indian Point since before the Three Mile Island accident in 1979. They fear radioactive contamination from an accident at the plant could cause numerous deaths and injuries in the heavily populated New York City metropolitan area.

Entergy, of New Orleans, owns and operates about 30,000 MW of generating capacity, markets energy commodities, and transmits and dist-ibutes power to 2.7 million customers in Arkansas, Louisiana, Mississippi and Texas. (Reporting by Scott DiSavino; Editing by John Picinich)
