The Ministry of Defence Police say they do not have enough officers to keep watch over British missile sites and submarine bases. They revealed a shortfall of hundreds of constables, and say officers are working themselves to the bone to keep facilities protected. Despite a recruitment drive, the department only managed to expand its workforce by five officers in an entire year because so many quit.

Analysis of passive safety systems in nuclear reactors has identified a number of intrinsic difficulties that need further research, France’s Institute for Radiological Protection and Nuclear Safety (IRSN) has said. In a report published today IRSN says the intrinsic difficulties particularly concern the assessment of performance and reliability of such systems. The report says further research is needed to properly assess the performance and reliability of passive safety systems to be implemented in new reactor designs. The report says assessing the performance of passive safety systems requires a very good understanding of the physical phenomena underlying their operation, as well as the necessary simulation capabilities for such phenomena. It says assessing reliability calls for specific development approaches in order to properly evaluate the reliability of passive safety systems, with particular emphasis on assessing the failure probabilities of thermal-hydraulic mechanisms used by these systems. IRSN said certain reactor designs proposed by nuclear power plant designers make more extensive use of passive safety systems to bring the reactor to a safe shutdown state and maintain this state for a long period of time – 72 hours for Westinghouse AP1000 reactors – without human intervention and with limited reliance on support functions.
