HC Deb 12 June 1989 vol 154 cc265-6W
Mr. Cohen

To ask the Secretary of State for Energy if he will list how many natural circulation tests have been carried out in the United Kingdom's Magnox nuclear power stations giving their locations; and if he will make a statement.

Mr. Michael Spicer

This is an operational matter for the Central Electricity Generating Board, and British Nuclear Fuels plc. They are responsible for the operation of Magnox power stations in England and Wales. I will ask their respective chairmen to write to the hon. Member.

Mr. Cohen

To ask the Secretary of State for Energy if the Central Electricity Generating Board has indicated to him how it intends to deal with the Wigner energy problem at Berkeley nuclear power station now that both reactors have been closed down; and if he will make a statement.

Mr. Michael Spicer

I am advised by the CEGB that Wigner energy does not present a problem in the decommissioning of Berkeley power station. The board will have to satisfy the Health and Safety Executive's nuclear installations inspectorate before undertaking each stage of decommissioning.

Mr. Cohen

To ask the Secretary of State for Energy if the Central Electricity Generating Board has any plans to carry out natural circulation tests at any of the operational Magnox power stations to further research into understanding the Wigner energy problem; and if he will make a statement.

Mr. Michael Spicer

I am advised that natural circulation tests on nuclear plant have no connection with research into understanding the Wigner energy phenomenon. Any natural circulation tests would be subject to the agreement of the Health and Safety Executive's nuclear installations inspectorate.
