1.0 PURPOSE The purpose of this procedure is to restore and stabilize RPV water levels.

2.0 ENTRY CONDITIONS The entry conditions for this procedure are any of the following:

2.1 RPV water level less than 12.5" ,

2.2 Drywell pressure greater than 1.69 psig 2.3 An isolation condition exists which requires g initiates reactor scram.

3.0 OPERATOR ACTIONS 3.1 Confirm initiation of any of the following.

3.1.1 VERIFY reactor scram and PERFORM SP 29.910.Dl, Emergency Shutdown, concurrently with this procedure.

3.1.2 VERIFY system isolations consistent with plant parameters.

3.1.3 VEP.IFY automatic initiation of ECCS systees and RBSVS system consistent with plant parameters.

3.1.4 VERIFY diesel generators start consistent with plant j parameters.

l 3.2 INITIATE cny cf th2 acticns of 3.1 which should havs initintsd but.did not.

CAUTION Avoid RPV high water level trip (58.75") of RFP, HPCI, and RCIC turbines.

3.3 Restore and maintain RPV water level between 12.5" and 58.75" with one or more of the following systems:

3.3.1 Feedwater/ Condensate 1115 to O psig 3.3.2 CRD 1115 to O psig 3.3.3 RCIC 1115 to 50 psig 3.3.4 HPIC 1115 to 100 psig 3.3.5 C.S. 333 to O psig 3.3.6 LPC1. 238 to O psig 3.4 If RPV water level can be restored and maintained above 12.5" and it'is determined that an emergency does not exist, enter the appropriate station procedure as determined by Shif t Supervision.

3.5 If RPV water level cannot be restored and maintained above +

12.5", maintain RPV water level above top of active fuel (TAF)

(A) TAF = +6" as read on fuel zone instrumentation L1-007 3.6 If RPV water level cannot be determined or maintained above TAF enter SP29 923 94 (Level Restoration).

CAUTION Notify the Watch Engineer to classify the event and initiate the proper emergency procedures.

3.7 If SRV's are cycling, open one SRV and reduce RPV pressure to between 799 and 960 psig to minimize SRV cycling. (Alternate

' SRV's to equalize suppression pool heating if this step must be repeated using Figure 1 as a guide) 3.8 When the RPV water level has stabilized, enter 29.923.92 (cool down).
