8. Isolation:

MOVs : 1-8701 A and !-8702A In order to prevent a LOCA outside the containment, during a shutdown operation, either one of the isolation valves needs to close. In order to prevent boiling, the operator needs to recognize the problem, isolate the break and establish a primary makeup source. Multiple means of detecting the problem will be available: low RCS level and high temperatures, area sump alarms, and radiation monitors. It is assumed that the operator has an error probability of IE-02 for early problem detection and isolation of the break.

If this isolation fails, later in the event, operators are assumed to have another opportunity to iiolate and establish core cooling. This late isolation is credited at IE-03. Total operator failure to isolate is estimated to be I E-05

9. Time to Isolate:

Estimate time for isolation, to prevent a LOCA outside Containment, is approximately one hour. This is based on an estimated time to drain the RCS to the hot legs, and subsequent time to boil
