{{#Wiki_filter:Point Beach Nuclear Plant PBNP SHUTDOWN SAFETY ASSESSMENT AND FIRE CONDITION CHECKLIST Date: May 11, 2004 Time: 1400 Preparer: Jon Leiker U I R 28 NOTE: Refer to base procedure NP 10.3.6 for sasfed assessment checklist KSF definitions. NOTE: Whenever ftel has been reinovedfroyn the reactor vessel and refueling cavity, all key safety fitnctions are GREEN except spent fiel pool cooling.

Look-ahead #2: While reactor vessel internals are being moved and also when rods are being latched, we will lose 1 point for Reactivity and 1 point for Containment. During internals movement, use TTB curves in Att. A of NP 10.3.6. Look-ahead #3: When reactor vessel internals are in place, we will lose 1 point for Inventory and 1 point for Containment (assuming no CFCs are available). Until cavity level is lowered, use TTB curves in Att. A of NP 10.3.6. PBF.1562 Revision2 1013(VO0
