- CONTROL ROD DRIVE HYDRAULIC CONTROL UNIT St"tVELLLANCE PROCEDURE 6.4.1.8 ACCUMULATOR LEAKAGE TEST I. PURPOSE ,
To provide a detailed instruction for station personnel to perform a con-trol rod drive hydraulic control unit accumulator charging water check valve and scram inlet control valve leakage check.
II. DISCUSSION ,
The control rod drive hydraulic control units are charged to a pressure of 1400 to 1500 psig, providing a source of water to rapidly insert the con-trol rods upon a signal from both buses of the reactor protection system.
At high reactor pressures (N above 800 psig) the accumulator provides for a rapid initial insertion rate for the control rods. As the accumulator pressure approaches reactor pressure, the control rod insertion continues ,
by reactor pressure internally ported within the control rod drive.'
At reactor pressures above 800 psig, required control rod scram times may be met independent of accumulator action, .Below-800 psig reactor pressure, accumulator operation is necessary in or' der to meet the required control rod scram times.
The purpose of this surveillance procedure is to ensure control rod drive hydraulic accumulators are capable of staying pressurized for 20 minutes in the event of loss of capability to charge them, such as a loss of both control rod drive pumps for an extended period of time. A second purpose of this procedure is to determine the leakage path so that proper subse-quent repairs may be initiated and post maintenance Q.C. can be addressed.

I. PROCEDURE
A. Identification Of Control Rod Drive Hydraulic Accumulators Which Leak Excessively.
- 1. Obtain the Shift Supervisor's permission to perform surveillance procedure.
- 2. Verify the control rod drive hydraulic control units accumulator nitrogen pressures are reading normal pressure between N 1090 and 1140 psig (refer to System Operating Procedure 2.2.8, Appendix C.
Figure II, Accumulator Recharge Pressure vs. Ambient Temperature).
Recharge any accumulators which are low per System Operating Pro- ,
cedure 2.2.8, Step VIII.E. -
- 3. With the control rod drive hydraulic system operating normally, secure the operating control rod drive hydraulic pump.

. 4. Utilizing a stopwatch, monitor the control, rod drive accumulator trouble alarm lights on panel 9-5 for 20 minutes.
- a. Record the control rod drive accumulator alarms and the time req sired from securing of the control rod drive pump until the alarm lights illuminate, on Attachment "A" data sheet.
Note: An alternate method could be to monitor the local hy-draulic control units accumulator alarm panels lights.
- 5. Restart the control rod drive pump and return the control rod drive hydraulic system to' normal per System Operating Procedure 1 2.2.8, Step VIII.
- 6. Perform Section B., if necessary, to determine leakage path for those accumulators.
B. Determining Accumulator Leakage Paths. ,
- 1. With the control rod drive hydraulic system operating normally, 4 verify accumulator trouble alarm lights are all.off.' -
- 2. Close CRD-29, charging header rdot valve, and immediately secure the operating control rod drive hydraulic pump.

- 3. Utilizing a stopwatch, monitor the control rod drive accumulator
- trouble alarm lights on panel 9-5 for 20 minutes. l
- i j a. Record the control rod drive accumulator alarms and the time l required from closing CRD-29 and securing the control rod 1 drive pump until the alarm lights illuminate, on Attachment "A" data sheet.
Note: An alternate method could be to monitor the local hy-draulic control units accumulator alarm panels lights.
- 4. Open CRD-29 after 20 minutes.
- 5. Restart the control rod drive pump and return the control rod drive hydraulic system to normal per System Operating Procedure 2.2.8, Step VII. -
- 6. Notify the Shift Supervisor'when testing is complete.
t Note: Those hydraulic control units accumulators which failed .
- to hold pressure during performance of Section VII.B. have leaking scram inlet control valves.
Those leaking hydraulic control units accumulators 1denti-
~
fled in Section VIII.A. but did not leak down in Section i VIII.B. have leaking charging' water check valves.
