HC Deb 18 March 1968 vol 761 cc2-3W
27. Mr. Gresham Cooke

asked the Minister of Technology what measures have been taken to improve security at Atomic Energy Authority establishments since the investigation into the damage to steam-generating heavy water reactors at Winfrith was completed.

Mr. Benn

The Steam Generating Heavy Water Reactor project is unclassified and military security was not involved in this incident. The Authority have, however, carried out a comprehensive review of the arrangements for protecting unclassified projects at their sites. This has shown that the arrangements are generally satisfactory; but in future special attention will be given to certain aspects of them in cases in which intentional or unintentional damage would have particularly serious consequences.
