ENCLOSURE VOGTLE ELECTRIC GENERATIB G PLANT-UNIT 2 REPLY TO A NOTICE OF VIOLATION NRC INSPECTION REPORTS 50-424:425/95-11 The following is a transcription of the violation as cited in the Notice of Violation (NOV):
"During the NRC inspection conducted on March 19 through April 15,1995, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedures for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violation is listed below.
Technical Specification 3.9.4, Containment Building Penetrations, states that during core alterations penetrations providing direct access from the containment atmosphere to the outside atmosphere shall be either closed by an isolation valve, blind flange, or manual valve, or be capable of being closed by an operable automatic containment ventilation isolation valve.
Contrary to the above, on March 9 and 18,1995, during core alterations, Unit 2 containment integrity was not maintained. On March 9,1995, during core alterations, control room personnel opened reactor coolant pump #2 seal injection system containment isolation valve,2HV-8103B, providing direct access from containment atmosphere to the outside atmosphere. On March 18, during core alterations, control room personnel opened atmospheric relief valve,2PV-3020, providing direct access from the containment atmosphere to the outside atmosphere.
This is a Severity Level IV violation (Supplement 1) (Unit 2 only)."
RESPONSE TO VIOLATION (50-425/95-11-01)
Admission or Denial of the Violation:
This violation occurred as stated in the notice of violation. The short period of time that 21IV-8103B valve was opened for valve stroke testing on March 9 and 10,1995, represents a minimal risk for the release of radioactive materials. Similarly, the twenty-two minutes that 2PV-3020 was opened on March 18,1995, also represents a minimal period of risk, since this pathway was partially filled with water that would have inhibited any release. Finally, during the periods involved, there were no radioactive releases in the containment building that might have led to a release of radioactive materials to the outside atmosphere. Based on these considerations, there was no adverse afTect to plant safety or to the health and safety of the public as a result of this violation.
,hason for the Violation:
The cause of this violation was attributed to an inadequate tracking mechanism to follow maintenance activities stillin progress or started after containment closure had been
- verified, l

ENCLOSURFo VOGTLE ELECTRIC GENERATING PLANT - UNIT 2 REPLY TO NOTICE OF VIOLATION NRC INSPECTION REPORTS 50-424:425/95-11 Other factors that contributed to this violation were:
- 1) Inadequate re-scheduling of work affecting containment closure, prior to and during fuel movement, without appropriate trackirg mechanisms.
- 2) Inadequate turnover communications among departments that controlled plant activities. Personnel working the night of March 17,1995, understood the potential for the work on the wet lay-up line valves to affect containment closure, but this knowledge was not adequately communicated to personnel working the dayshift on March 18,1995.
- 3) The absence of adequate coding or other means to identify work documents that may impact containment closure.
Corrective Stens Which Ilave Been Taken and the Results Achieved:
Control room personnel immediately closed valve 2PV-3020 at 1545 on March 18,1995, when they received a report of water coming from the vicinity of steam generator
- 3. ARer discussion with plant managemem, the decision was made to stop core alterations and review containment integrity status. This action was taken to ensure that further containment integrity breaches would not occur due to on-going maintenance and operations activities. Plant management subsequently directed that both incidents of breaching containment integrity be investigated by an Event Review Team to determine cause and propose the appropriate corrective actions to prevent recurrence.
Corrective Steos Which Will Be Taken to Avoid Further Violations:
- 1. Future outage scheduling will utilize work order coding to assist in minimizing the j
affect on containment integrity ofwork performed during core alterations. Appropriate surveillances, clearances, and equipment databases will be coded by February 15, 1996, as potential containment integrity impacts.
- 2. To prevent recurrence of this violation during future refueling ounges, an improved tracking method will be implemented by February 1,1996, to facilitate control of work activities to ensure containment integrity is maintained.
- 3. Discussion of this violation to stress the need for accurate documentation and shin turnovers will be presented to the appropriate operations, maintenance, and work planning personnel by September 30,1995.
