HC Deb 22 May 1978 vol 950 cc440-1W
Mr. Skeet

asked the Secretary of State for the Environment whether there is a commercial plant or process available suitable for the removal of krypton gas from nuclear plant discharges.

Mr. Shore

Although at present there is no commercial plant or process for the removal of krypton gas available in the United Kingdom, small-scale processes for krypton 85 extraction have been tested here, and a pilot storage plant is in operation. Plant for the extraction and retention of the small amount of krypton arising from reactors is being used in the United States, and larger-scale processes are being developed and tested in pilot reprocessing plant in several other countries. The oxide reprocessing plant (THORP) is to be designed so as to enable a krypton removal plant to be incorporated.
