Regulatory Gap Analysis of Select NUREG-0800 Chapters for Applicability to Molten Salt Reactors
The past licensing approach for advanced reactors was based on adapting the current LWR-based NRC process that exists today to the advanced reactor concept. This is the approach used by advanced technologies such as the Pebble Bed Reactor licensing application, the Clinch River Breeder Reactor licensing application, and more recently the NuScale licensing application. Current Standard Review Plan (SRP) guidance for large LWRs is available in NUREG-0800, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: Light Water Reactor (LWR) Edition. However, the SRP is cumbersome to apply to liquid-fueled molten salt reactor (MSR) technologies. Therefore, a thoughtful licensing approach for MSRs is necessary.This report documents for DOE-NE an additional regulatory gap analysis of select chapters from the LWR SRP to further inform a generic nonpower MSR test program. Although the review process outlined in NUREG-0800 is LWR-specific, the plant functions and processes to be reviewed will be similar for the MSR. Therefore, a well-planned nonpower MSR test program can provide the performance data needed to better facilitate the eventual commercial-sized MSR review. The LWR SRP chapters dealing with the reactor, reactor coolant, engineered safety features, auxiliary systems, and waste management systems were reviewed.
