HC Deb 19 March 1990 vol 169 cc433-4W
Mr. Flynn

To ask the Secretary of State for Defence if he will set out the specific reasons for the amendments made respectively in each case since 1959 to the 1958 United Kingdom-United States mutual defence agreement on atomic energy matters.

Mr. Archie Hamilton

The amendments to the 1958 agreement between the Government of the United Kingdom of Great Britain and Northern Ireland and the Government of the United States of America for co-operation on the uses of atomic energy for mutual defence purposes and the reasons for their implementation were:

Cmnd 859 (l959)—to permit the transfer between the two countries of nuclear materials, other than submarine propulsion materials which had been agreed upon in the original agreement, for military purposes.

Cmnd 4119 (1969)—to extend the range of material transfer clauses

Cmnd 4384 (1970)—to extend the duration of the material transfer clauses

Cmnd 6017 (1975)—to further extend the duration of the material transfer clauses

Cmnd 7976 (1980)—again to further extend the duration of the material transfer clauses and also to add a minor change to the wording of the contraints upon each part as applied by the conditions clauses

Cmnd 9336 (1984)—a further extension of the duration of the material transfer clauses, the provision of materials processing services, and a major change to the wording of a number of clauses to ensure the appropriate protection of US "sensitive nuclear technology information" and "controlled nuclear information"—two new classes of US information which had been created by changes in US federal law.
