SIRTM REACTOR SAFETY AND DECOMMISSIONING

This Paper describes in broad terms the safety principles of the SIR(TM) integral PWR. It discusses the safety provisions of the design and emphasizes particularly those inherent and passive features which allow 72 hours of safe response to any design basis accident without operator action and without safety grade AC electrical supplies. The Paper goes on to show how the SIR(TM) reactor plant can be decommissioned. Four options have been investigated and the dose burdens and cost estimates are very attractive to owners compared with other PWR systems.
