HC Deb 22 January 1990 vol 165 cc581-2W
Mr. Flynn

To ask the Secretary of State for the Environment what volumes of radioactive waste are currently disposed of at Clifton Marsh; what radionuclides are deposited; how many bequerels of(a) gamma, (b) beta and (c) alpha radioactivity are at the site; and when disposal of radioactive waste was first begun at Clifton Marsh.

Mr. Trippier

Radioactive wastes disposed of at Clifton Marsh originate from British Nuclear Fuels plc's plant at Capenhurst and Springfields and are measured by weight (tonnes) not by volume. In 1988 a total of 10,000 tonnes was disposed of which equates to approximately 6,600 sq. m.

Uranium and its short-lived daughter radionuclides are authorised for disposal at Clifton Marsh.

It is estimated that for the period up to 1988 0.7 terabecquerels of alpha activity and less than or equal to 0.7 terabecquerels of beta/gamma activity have been disposed of at Clifton Marsh.

Disposals at Clifton Marsh commenced in 1974.
