The Scottish Government has not carried out any formal risk assessment regarding Nuclear Decommissioning Authority (NDA) and Ministry of Defence (MOD) civil defence co-operation and the proposal to transfer any defence liabilities to the civil sector as no formal proposal to transfer any such liabilities has been presented to us.We are aware of technical work being conducted by NDA and MOD to evaluate the potential transfer of the Vulcan Naval Reactor Test Establishment, near to Caithness, to the NDA when the site reaches the end of its operational life, not expected to be before April 2027, and we will consider the results of this in due course.
