Beaver Valley Power Station, Unit Nos. I and 2 Reply to Notice of Violation Letter dated July 3.1997 VIOLATION (Severity Level lilt Supplement I)

EA 97-255 Unit I and Unit 2 Technical Specification (TS) 4.0.2 require that, each surveillance requirement shall be performed within the specified time interval.

1. Unit 1 TS 4.8.1.1.2.b.5 requires that each diesel generator shall be demonstrated OPERABLE at least once per 18 months during shutdown by verifying the diesel generator operates for greater than or equal to 60 minutes while loaded to greater than or equal to 2750 KW.

Contrary to the above, on April 11,1996, and April 20, 1996, during emergency diesel generator (ECO) surveillance tests, the load test values used were inadequate to ensure that the EDGs achieved 2750 KW due to inaccuracies in the kilowatt meter instrument loop. Specifically, the EDGs had to be tested to at least 2875 KW to account for meter inaccuracies; however, EDO 11 was tested at 2850 KW on April 20,1996, and EDO l 2 was tested at 2800 KW on April 11,1996. These were the only EDG surveillance tests perfonned to meet TS 4.8.1.1.2.b.5 during the 18-month period. (01013)

2. Unit I and Unit 2 TS 4.4.6.3.1 require, in part, that leakage testing of reactor coolant system (RCS) pressure isolation valves (PlVs) listed in Table 4.4. 3 shall be accomplished prior to entering Mode 2 after every time the plant is placed in the COLD SHUTDOWN condition for refueling. Unit 1 TS Table 4.4-3 includes, in part, residual heat removal (RHR) system inlet isolation valves MOV RH-700 and MOV-RH-701. Unit 2 TS Table 4.4-3 includes, in part, RHR system inlet isolation valves 2RHS MOV701 A,2RHS-MOV702A,2RHS-MOV701B, and 2RHS-MOV702B, Contrary to the above, Unit I reactor coolant system (RCS) pressure isolation valves MOV RH-700 and 701 were not leak tested prior to entering Mode 2, after placing the unit in cold shu'Jown on March 23, 1996. Additionally, Unit 2 RCS pres:ure isolation valves 2RHS MOV701 A(B) and 2RHS MOV702A(B) were not leak tested prior to entering Mode 2, after placing the unit in cold shutdown on September 1, 1996.(01023)

3. Unit I and Unit 2 TS 4.6.4.2.b.4 require that each hydrogen recombiner system shall be demonstrated OPERABLE at least once per 18 months by verifying the integrity of all heater electrical circuits by performing a continuity and resistance to ground test immediately following the functional test required by TS 4.6.4. 2.b.3.

Contrary to the above, on March 24, 1996, the integrity of Unit I hydrogen recombiner IA and IB heater circuitry was not verified immediately following the functional tests of the recombiners. On September 1,1996, the integrity of Unit 2 hydrogen recombiner 21A and 21B heater circuitry was not verified immediately following the functional tests of the recombiners. (01033)

4. Unit I and Unit 2 TS 4.3.1.1.1 require that each reactor trip system instrumentation channel shall be demonstrated OPERABLE by the performance of the CHANNEL CHECK, CHANNEL CAllBRATION, and CHANNEL FUNCTIONAL TEST operations during the modes and at the frequencies shown in Table 4.3 1.

Unit I and Unit 2 TS 4.3.2.1.1 require that each engineered safety feature actuation system (ESFAS) instrumentation channel shall be demonstrated OPERABLE by the performance of the CHANNEL CHECK, CHANNEL CALIBRATION, and CHANNEL FUNCTIONAL TEST operations during the modes and. at the frequencies shown in Table 4.3-2.

Unit I and Unit 2 TS 4.3.2.1.2 require that the logic for the interlocks shall be demonstrated OPERABLE during the at power CHANNEL FUNCTIONAL TEST of channels affected by interlock operation.

Contrary to the above, prior to March 24,1997, and March 27,1997, respectively, the Unit I and Unit 2 reactor coolant system loop stop valve position block signals were not tested during bimonthly channel functional testing for ESFAS instrumentation, and channel functional testing for reactor trip system instrumentation, in addition, an ESFAS P-4 interlock logic diode in the Unit I and Unit 2 solid state protection system logic circuits was not tested during channel functional testing. These testing omissions resulted in failure to demonstrate the interlock logic and the interlock function operable. (01043)

5. Unit I and Unit 2 TS 4.0.5.a.2 require that inservice testing of ASME Code Class 1, 2, and 3 pumps and valves shall be performed in accordance with Section XI of the ASME Boiler and Pressure Vessel Code and applicable Addenda as required by 10 CFR 50.55a(f).

Unit 1 TS 4.7.7.2.b.1 requires that the bottled air pressurization system shall be demonstrated OPERABLE at least once per 18 months by verifying that a

Unit 2 TS 4.7.7.1.e.6 requires that the Control Room Emergency Air Cleanup and Pressurization System shall be demonstrated OPERABLE at least once per 18 months by verifying that a chlorine / control room high radiation / containment phase B isolation signal will initiate

- operation of the bottled air pressurization system.

Operating Surveillance Test 1/20ST-44A.ll, " Chlorine Actuation of Control Room-Isolation /CREBAPS Systems," implements the surveillance requirements and requires that the stroke times for the discharge trip valves do not exceed a prescribed ASME limiting stroke time. The test also requires that, if the discharge trip test valves exceed their previously recorded stroke times by greater than 50%, the test frequency will be increased to monthly.

Contrary to the above, CREBAPS discharge trip valves TV VS-101 B, D, and E were not stroke time tested between January 29 and March 22, 1997, following a 50%

stroke time increase measured during performance of I /20ST-44 A.11 on January 28,

-1997.(01053)

6. Unit 1 TS 4.1.2.2.b and Unit 2 TS 4.1.2.1.b require that at least oac of the required boron injection flow paths shall be demonstrated OPERABLE at leist once per 31 days by verifying that each valve (manual, power operated or automatic) in the flow path that is not locked, scaled or otherwise secured in position, is in its correct position.

Contrary to the above, prior to March 25,1997, the monthly boron injection flowpath operability verifications were not satisfactorily completed. Specifically, position verifications for boron injection flowpath valves MOV-lCH-289 and 310 and ICH-83 and 86 on Unit I and 2CHS MOV289 and 310 on Unit 2 (valves which were not locked or secured in position) were not performed. (01063)

These violations are classified in the aggregate as a Severity Level III problem (Supplement I),

Reason for the Violations The root cause of the violations was inadequate management oversight and control of the TS surveillance program. Contributing factors were weaknesses in the procedures, scheduling, coordination and communication processes used for surveillance testing.
