The shadow of an old accident haunts Britain’s nuclear revival
THIS is a big week in the government’s attempt to rehabilitate nuclear energy. Eight months after a court ruled that its first public consultation on whether to build more reactors had been misleading and unfair, its second attempt finished on October 10th. For a government with (until recently) a reputation for slick public relations, that date looks ill-judged. For it also marks the 50th anniversary of a fire at the Windscale nuclear reactor in Cumbria that was, until Three Mile Island in 1979, the world’s worst atomic accident (the Chernobyl explosion in 1986 dwarfs both).

The official cost of cleaning up 20 of Britain’s nuclear facilities will be more than £73bn, 16% higher than estimated last year, according to the Nuclear Decommissioning Authority yesterday. The latest rise in clean-up costs came as the government completed consultation on whether to proceed with a new generation of atomic plants, with one potential operator arguing there was a “moral imperative” to allow more to be built.

Producer, Windscale: Britain’s biggest nuclear disaster

Fifty years ago, on the night of 10 October 1957, Britain was on the brink of an unprecedented nuclear tragedy. A fire ripped through the radioactive materials in the core of Windscale, Britain’s first nuclear reactor. (more…)

London (Platts)–24Aug2007The UK’s Oldbury-2 magnox reconnected to the grid August 23, operatorMagnox North said August 24. A fire and then turbine vibrations kept thereactor offline most of the time since May 30. Oldbury-2, one of the fourremaining operating magnox reactors, underwent a 23-month outage until May 27to determine the extent of graphite depletion in its core. It operated onlythree days before a May 30 fire on the non-nuclear side of the plant forcedits shutdown. It returned to service June 30, only to be shut again in early July following the turbine vibration problem.

Sister unit Oldbury-1 has been offline since August 31, 2006, alsounder going graphite weight loss checks. Its safety analysis work for return to service is with regulator Nuclear Installations Inspectorate. Oldbury-1 and -2 are due to close permanently in December 2008 and have experienced higher levels of graphite weight loss than the rest of the almost fully retired 11-station (26-reactor) magnox fleet.
