PHASE 2 - RE-ANALYSIS OF NS SAVANNAH LOSS-OF-COOLANT ACCIDENT
Phase II of a re-analysis examined post-accident heat Phase 2 of a re-analysis examined post-accident heat and analyzed the effect on the loss-of-coolant accident of utilizing the available cooling. The study was limited to the Phase I results of breaks of the inlet and outlet lines which were shown to be the limiting case in terms of core heatup and fuel slumping. Results of the study included: (1) the only effect post-accident core cooling supply is that portion of the buffer seal system charging water which is injected into the reactor pressure vessel through the rod drive mechanism buffer seals; (2) if all the buffer seal orifices are plugged, the available injection rate does not prevent 100% core melting; (3) if they are open, the available injection rate limits core melting to a maximum of 8%; (4) supplements to the normal containment heat sinks provide storage for the core decay heat generated over a 237-hour period, after which one of the available means of containment heat removal must be initiated. Figures comprise over half of the report.
