Problems at Hunterston B (UK). About 10% of graphite bricks in the core are found to be damaged. That seems to me to be a very high precentage.

The first pictures have emerged of cracking in the graphite bricks which make up the core of nuclear reactors at Hunterston B Power Station in Ayrshire.

Reactor three has not produced electricity since cracks were found to be forming quicker than expected.

About 370 hairline fractures have been discovered which equates to about one in every 10 bricks in the reactor core.


But they want to crack on with producing more power (until 20% of the bricks are damaged..

EDF plans to ask the regulator for permission to restart with a new operational limit of up to 700 cracks.

Federal Government Ups Its Commitment To Plant Vogtle, Secretary Perry Visits

Secretary of Energy Rick Perry visited Plant Vogtle for the first time Friday, to announce the federal government would guarantee $3.7 billion more in loans to the nuclear power plant’s expansion project.

Perry was joined by Governor Brian Kemp and Secretary of Agriculture and former Georgia Gov. Sonny Perdue for the announcement. They also witnessed the “tuopping out” of the containment vessel for one of the new reactors. That’s the building that actually holds the nuclear reactor.

The plant, in Waynesboro, is the only one under construction in the country, and would be the first new one in more than 30 years. With $8.3 billion in loans already guaranteed by the Obama administration in 2011, this brings Vogtle’s total federal support to $12 billion.

The expansion of Plant Vogtle with nuclear reactors 3 and 4 has had a delayed and expensive history. Both units were already supposed to be on the grid by now, and the project’s current budget is double the original estimate, at more than $25 billion, split between four owners, the largest being Georgia Power.

Secretary Perry touted his strong support for nuclear energy as part of an “all of the above energy strategy” of the administration before a crowd of Vogtle employees: “Ladies and gentleman look around you, this is the real new green deal. That’s what we’re looking at folks. This is America. This is what we can do together.”

“If you want clean energy that helps our environment, there is no cleaner source than nuclear energy. This is it,” he said, calling nuclear and coal the only two sources of energy “that are on site and uninterruptable.” .......
