HC Deb 25 March 1991 vol 188 c300W
Mr. McFall

To ask the Secretary of State for Defence what review his Department has made of the safety of the existing designs and designs currently under development of nuclear warheads; what application of three-dimensional modelling has been used; and what reconsideration has resulted of the safety case for an actual nuclear explosion which might be accidentally or unintentionally initiated leading to the dispersal of radioactivity and/or a nuclear yield.

Mr. Archie Hamilton

All of the United Kingdom's nuclear warheads are designed to meet stringent safety requirements. Before entering operational service, the designs are subject to a comprehensive series of trials and assessments, encompassing normal and credible abnormal environments of in-service life, and to formal safety approvals procedures, which are assessed independently. In addition, the United Kingdom conducts a continuous safety review of all operationally deployed designs by way of routine examination and sophisticated modelling.
