Uninterruptible Monitoring of Coolant and Fuel in Reactors and Spent Fuel Pools

The U.S. Nuclear Regulatory Commission (NRC) has received a petition for rulemaking (PRM) requesting that the NRC amend its ``Domestic licensing of production and utilization facilities'' regulations to require ``installation of ex-vessel instrumentation for uninterruptible monitoring of coolant and fuel in reactors and spent- fuel pools.'' The petition, dated September 10, 2015, was submitted by Dr. Alexander DeVolpi (the petitioner). The petition was docketed by the NRC on September 21, 2015, and was assigned Docket Number PRM-50- 113. The NRC is examining the issues raised in this petition to determine whether they should be considered in rulemaking. The NRC is not requesting public comment on PRM-50-113 at this time.
