Nuclear safety philosophy and its general application to fuel management and handling - a - a regulator's viewpoint

摘要

The Nuclear Safety Division (NSD) of the Health and Safety Executive (HSE) informs the UK nuclear industry of the principles that it applies in assessing whether licensees have demonstrated that their nuclear plants are as safe as is reasonably practicable. This information was first published in the form of Safety Assessment Principles (SAPs) in 1979 for nuclear reactors and in 1983 for nuclear chemical plant. The Layfield Report after the Sizewell B Inquiry recommended that HSE should also publish its thinking on tolerable levels of risk, and this led to the publication, in 1988, of a paper entitled the tolerability of risk (TOR). As a result of comments received and discussions at the Hinkley Point C Inquiry, TOR was updated and republished in 1992. In parallel with this, the SAPs were revised to take account of the risk-based approach described in TOR, and were reissued also in 1992. The safety philosophy applicable to nuclear fuel handling and management is embodied in these documents. This paper covers those parts of the SAPs which apply to this particular aspect of nuclear safety.
