§ Mr. Cookasked the Secretary of State for Energy if he will estimate the total amount of plutonium contained in all Great Britain's magnox reactors, including Calder Hall and Chapelcross, at 31 September 1981.
§ Mr. John MooreOn 30 September the United Kingdom civil magnox reactors contained about 8½ tonnes of civil grade plutonium. This is an integral part of the fuel resulting from irradiation in the reactor and constitutes 0.15 per cent. of the total magnox fuel mass. This level is constant at current levels of irradiation.
