| Probabilistic Risk Assessment of a Light Water Reactor Coupled with a High-Temperature Electrolysis Hydrogen Production Plant – Part 2: Hazards Assessment and PRA |
|---|
| Generic PRA have been performed for the addition of a heat extraction system to a pressurized-water reactor and a boiling water reactor. The results investigate the applicability of the potential licensing approaches which might not require a full U.S. Nuclear Regulatory Commission (NRC) licensing amendment review (LAR). The PRA draw on the design data for the heat delivery and high-temperature electrolysis facility developed by the Light Water Reactor Sustainability Program. The results of the PRA indicate that application using the licensing approach in 10 CFR 50.59 is justified because of the minimal increase in initiating event frequencies for all design basis accidents (DBAs), none exceeding 5.6%. The PRA results for core damage frequency (CDF) and large early release frequency (LERF) support the use of Regulatory Guide 1.174 as further risk information that supports a change without a full LAR. Further insights provided through hazard analysis and sensitivity studies confirm with high confidence that the safety case for licensing an HES addition and an HTEF sited at 1.0 km from the nuclear power plant is strong and that the placement of an HTEF at 0.5 km is a viable case. Site-specific information can alter these conclusions. |
