27. Mr. Gresham Cookeasked the Minister of Technology what measures have been taken to improve security at 3W Atomic Energy Authority establishments since the investigation into the damage to steam-generating heavy water reactors at Winfrith was completed.
§ Mr. BennThe 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.
