REACTOR PROTECTION SYSTEM Hope Creek Page 5 of 5 Rev. 3 SUBSEQUENT OPERATOR ACTIONS CONDITION ACTION

___ A.1 RESTORE Normal Power to the affected Bus. (if possible)

CAUTION 1 A.2 IF Normal Power cannot be restored:

a.

VERIFY Alternate Power is available.

b. TRANSFER Power to the Alternate Power Supply by POSITIONING the RPS MG SET TRANSFER SWITCH to the Alternate position. [CD324X]

A.3 RESET the 1/2 Scram as follows:

a. TURN the key for the Affected RPS channel(s) to the RESET position.

b. TURN the key BACK to NORMAL.

c. VERIFY the Scram is reset.

A.4 IF the MSIVs are OPEN THEN RESET the tripped NSSSS Logic as follows:

a. PRESS the NUCLEAR STEAM SUPPLY SHUTOFF SYSTEM TRIP LOGIC A(B,C,D) RESET Pb.

b. VERIFY MSIV TRIP LOGIC TRIPPED goes off.

A.

Loss of Normal power to RPS Bus Date/Time:

___ A.5 RESTORE isolated equipment IAW applicable SOP.

B.1 WHEN the cause of the trip is CORRECTED RESET the 1/2 Scram as follows:

a. TURN the key for the Affected RPS channel(s) to the RESET position.

b. TURN the key BACK to NORMAL.

B.

RPS Channel Trip.

Date/Time:

c. VERIFY the Scram is reset.

C.

SV-4310 OR 4311 have CLOSED.

Date/Time:

___ C.1 NOTIFY Chemistry to remove the RWR sample line from service IAW CH-SA.RC-0002.

REACTOR PROTECTION SYSTEM Hope Creek Page 1 of 1 Rev. 3 REVISION

SUMMARY

• Incorporates CP 80095664 which adds a statement that HWCI will trip on a full scram to the Automatic Actions. This was reviewed by the CP and is editorial. (60077918-0310)

• Deletes HV-F023 and HV-F022 in the table under Automatic Actions. These valves were reviewed deleted by CP. This is an editorial change. (20400419)
