l DUQUESNE LIGHT COMPANY Nuclear Power Division Beaver Valley Power Station, Unit No. I and No. 2 Reolv to Notice of Violation Integrated Inspection Report 50-334/98-03 and 50-412/98-03 i Letter Dated August 15,1998 VIOLATION (Severity Level IV, Supplement I)

Descriptica of Violation (50-334(412)/98-03-01)

Technical Specification 6.8.1.a requires that, " written procedures shall be established, implemented and maintained covering ... the applicable procedures recommended in Appendix "A" of Regulatory Guide 1.33, " Quality Assurance Program Requirements,"

Rev. 2, February 1978." Appendix "A" of Regulatory Guide 1.33 recommends procedures for surveillance testing, operation, and control of maintenance work (including clearances) for safety related equipment.

Contrary to the above, during the period April 28 through June 8,1998, the licensee failed to i,nplement procedures as evidenced by the following examples:

1. Procedure 2OST-30.13A, " Train A Service Water System Full Flow Test," Rev. 8, requires that the service water system be returned to the desired configuration as directed by the nuclear shift supervisor / assistant nuclear shift supervisor. The i procedure was not properly implemented, in that on May 29, after conducting the I

service water test, operators failed to properly restore service water to the "A" high head safety injection pump. The "A" high head safety injection pump was improperly considered operable and was thus improperly credited as part of an operable boration flow path from June 2 to June 8. On June 8, a licensed operator identified that service water was aligned to the "C" high head safety injection pump and not the "A" pump.

2. Procedure 1/2 OM-48.1.D, " Operations Shift Rules of Practice," Rev. 25, requires that if an instrument provides an apparent improper indicatior, the operator should

. believe the instrument and respond conservatively to prevent damage to station equipment unless the instrument indication is demonstrated 'to be false by checking against at least two redundant instruments. The proce. dure was not properly implemented, in that on May 22, operators did not respon4 conservatively when the branch flow line flow data for the high head full flow test indicated pump runout conditions. Testing continued without proper assessment of the indication of runout flow and the potential adverse effects on the high head safety injection pump.

3. Procedure NPDAP 3.4, "Clearancerfagout Procedure," Rev. 9, requires a senior l reactor operator to verify that the tagout is proper!y prepared. The procedure was not properly implemented, in that on June 3, the clearance for exhaust fan 222-B was not properly prepared and was posted. The clearance deenergized fan 222-B; however, '

the clearance also disabled the two emergency diesel generator roem ventilation fans, which was not recognized. Subsequently, the licensee identified EDG 2-2 inoperability when operators attempted to start an emergency ventilation fan and it failed to start. EDG 2-2 was inoperable for approximately four hours.

4. Procedure 2MSP-1.14B-I, " Train B Reactor Trip and Bypass Breaker Time Response ,

Test," Rev.1, sicp K.I.b requires the removal of the jumper that disabled the Unit 2 general warning trip. The procedure was not properly implemented, in that on  ;

May 10, operators discoveied that the jumper was still installed in the solid state protection system. The technicians failed to remove the jumper on April 28 as required in the procedure, despite requirements for double verification.

Reasons For The Violation For the examples cited in the violation, Examples 1 and 2 are attributable to a combination of human performance deficiencies and procedure weaknesses. In Example 3, the clearance was prepared based on load list information contained in the operating manual; however, this information was incomplete in that it did not provide details concerning the unique aspects of the circuit design. Example 4 was caused by a l human performance error by the Instmment & Control (I&C) Technicians involved, who I mistakenly believed that the procedure step to remove the jumper was optional.

Corrective Actions Taken and Corrective Actions Planned to Prevent Further Violations I

The corrective actions taken for each example listed in the violation are as follows:

1 Examole I l i

1. Condition Report 981236, concerning the service water full flow surveillance test, was written on June 8,1998, to document the problem for evaludion and resolution under the corrective action program.
2. Human performance issues related to Operations were reviewed by August 27,1998, between the Operations Manager and the operating crews at the periodic management-shift crew meetings that are held during the requalification training

7 -- .-

week. These sessions were used by the Operations Manager to review the

Operations Standards and management expectations regarding human performance, with emphasis on the need to reduce human performance errors.
3. The service water full flow surveillance test procedures (2OST-30.15A & B) were revised on September 1,1998. Changes included instructions to ensure that service water flow to the in-service high head safety injection (HHSI) pump is restored prior to the swapping of service water trains and/or from exiting the test procedure.

4 Example 2

1. The issues brought to the attention of Operations management by the NRC inspectors concerning the HHSI full flow surveillance test were immediately discussed with the operating crews involved in the test. The crews were reminded of management expectations and standards that emphasize the need to compare all process indications when conflicting data is obtained and to stop and resolve problems encountered during plant 09erations and/or testing before proceeding.
2. Procedure weaknesses noted during the performance of the test were identified and documented in an Operations Standard Surveillance performed on May 23,1998. I The Operations Star.dard Surveillance is a surveillance critiquing method periodically I used by the on-shift SROs to ensure surveillance procedures and their performance meet management expectations for Operations standards, as well as providing for an on-going quality check of procedural content and accuracy.
3. Condition Report 981251 was written on June 5,1998, to document the problem for evaluation and resolution under the corrective action program.
4. The HHSI pump full flow operations surveillance test procedure (2OST-11.14B) was revised on September 1,1998, to correct the deficiencies that were identified during the May 23,1998, performance. This surveillance test will be completed prior to Beaver Wiley Unit 2 (BV-2) entty into Mode 4 from its current extended outage.

Example 3

1. Condition Report 981194, concerning the inadequate load list information on the emergency diesel generator exhsust fans breakers, was written on June 3,1998, to document the problem for evaluation and resolution under the corrective action program.
2. The system power supply and control switch list, and MCC load list for the affected breaker (s) were revised by September 3,1998, to note that the opening of the EDG room exhaust fan breaker will render both EDG room supply fans unable to start due

i to the electrical configuration of the EDG room high temperature switch circuitry and the interlock relationship between the two supply fans. The changes to the load lists will help to ensure that future clearances for the EDG exhaust fans cannot occur without due consideration of EDG operability.

3. A keyword search of the Condition Report (CR) data base (from 1997 on) was j performed to determine other CRs associated with the keywords " load list." This j i

search resulted in 12 CRs, which were reviewed and none were attributed to be i caused by a deficiency in the station's various breaker load lists. In fact, in several 2 instances the detail contained in the load lists contributed to conservative decisions j being made that either prompted further research prior to proceeding, or, in one instance, greatly aided system restoration and contingency actions during the loss of a

. power panel. The uniqueness of this particular circuit's configuration is believed to be a major contributor to this event, and therefore, similar problems of this type are i i

not anticipated to occur.

4. Condition Report 981194 will be reviewed by the Operations Manager by
October 31,1998, with the operating crews at the periodic management-shift crew

[ meetings that are held during the requalification training week. Review of the

! condition report will be used to stress management expectations concerning the use of proper self-checking techniques, clearance review and approval requirements, and i the role of a questioning attitude.

j Example 4 1

i 1. Condition Report 981172, concerning the general warning trip jumper, was written i on May 29,1998, to document the problem for evaluation and resolution under the j corrective action program.

2. The technicians involved with the performance of the procedure were counseled by August 11,1998, on their failure to properly follow station procedures.
3. Procedures 2MSP-1.14A-I and 2MSP-1.14B-I were revised by August 20,1998, to completely remove optional instruction steps.
4. This event and the STAR (Stop, Think, Act and Review) concept will be reviewed with the Instrument and Control Technicians as part of their continuing training program by October 31,1998. In addition, site relay crew personnel will also review this event and the STAR concept as part of their continuing training program by

. December 31,1998. This training will emphasize the use of proper self-checking ,

techniques.

l i

Reply to Notice of Violation Inspection Report 50-334/98-03 and 50-412/98-03 i Page5 The examples listed above will also be included in scheduled training for the operating crews as past of the License and Non-License Requalification Training by December 31, 1998. This training will be used to heighten sensitivity to human performance errors on j

shift and review Operations Standards related to: conservative decision making when i challenged with instrument indication anomalies, pre-job briefing requirements, l conununicating to the crew activities affecting safety-related equipment, use of proper I self-checking / peer-checking techniques, and initiating corrective actions for deficiencies identified during surveillance testing.

In addition to the above, the following initiatives are being taken to improve human  !

performance: I

1. BVPS rece atly introduced the STAR (Stop, Think, Act, and Review) concept at the station as a preemptive measure to minimize human performance errors. Currently l being phased in station-wide, the STAR program is an improvement over the previous BEST (Before Each Step Think) program as it includes a review step to the self-checking sequence. STAR principles are emphasized to the operators during simulator and on-the-job training (OJT) exercises to further underscore the importance of proper self-checking and peer-checking techniques.
2. Prior to the startup of Beaver Valley Unit 1 (BV-1) from its extended outage, each department conducted standdowns to emphasize the use of the STAR concept during BV-1 startup activities. In addition, Operations managers and other senior managers provided 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> a day oversight of BV-1 startup activities to reinforce management expectations and standards to site personnel. Twenty-four hour management oversight will also be in place during BV-2 startup activities from the current outage.

Departmental standdowns are also planned prior to this BV-2 startup to re-emphasize the STAR concept.

3. Management will formalize a human performance program >+ Beaver Valley Units 1 and 2. A plan and schedule for implementation of this program will be developed by November 15,1998.

Date When Full Comoliance Will Be Achieved

1. Surveillance test 2OST-11.14B will be completed prior to BV-2 entry into Mode 4 from its current outage.
2. Condition Report 981194 will be reviewed with the operating crews by October 31, 1998.
