Webreactor (BWR) safety analysis. These include fast and slow transients, stability, loss-of-coolant accident (LOCA), and containment analysis. LOCA analysis is performed using the Westinghouse BWR Emergency Core Cooling System (ECCS) Evaluation Model. This model uses GOBLIN series of codes and complies with the NRC 10CFR50, Appendix WebBWR OWNERS’ GROUP MISSION. To provide a forum, in the spirit of partnership with GE, where utility members can: Achieve higher plant reliability; Maintain and improve plant safety; Minimize and share costs; Facilitate regulatory interaction; Login to …

The low pressure core spray (LPCS) starts to inject water when the pressure reaches values below about 2 MPa. In BWR-6-type reactors a high pressure system (high pressure core spray, HPCS) working in a similar way to the LPCS is also ...
