§ Ms Roseanna Cunningham
To ask the Secretary of State for the Environment what inquiries are being made into the climatic effects of krypton gas being released into the atmosphere as a result of uranium reprocessing. 
§ Mr. Clappison
I am not aware of any inquiries in progress at present. In 1993, Her Majesty's inspectorate of pollution published a report, entitled "A Review of the Potential Effects of the Release of Krypton-85", which had been prepared for it by the university of Manchester institute of science and technology. This confirmed the conclusion of an earlier study, commissioned by British Nuclear Fuels from Imperial college, London, that the reprocessing of spent nuclear fuel at the thermal oxide reprocessing plant at Sellafield would have insignificant effects on cloud microphysics.
