79. Mr. Alan W. Williams
To ask the Secretary of State for Defence what consideration he has given to safety and security arrangements in plants in the United Kingdom which produce beryllium oxide gas in connection with his Department's weapons production programme.
§ Mr. Kenneth Carlisle
None. Beryllium oxide is an extremely stable material which is used commercially as a protective coating for metals exposed to very high temperatures. It is not used, however, in the United Kingdom's nuclear weapons programme.
