ABSTRACT (Limit to* 1400 spaces, i.e., approximately 15 single-spaced typewritten lines) 116)
During system readiness review of the safety injection system, a question was raised relative to compliance with Technical Specification (TS) 6.8.4a.
TS 6.8.4a requires a program to monitor and reduce leakage from those portions of systems outside containment that could contain highly radioactive fluids during a postulated accident.
It was determined that elements of this leakage monitoring program exist, but they are presently not controlled as an integrated program. Leak rate data is not compiled for comparison with the licensing basis leak rate.
The cause of this event has been attributed to Management/QA deficiency.
Corrective actions taken include consolidation of the program under a single organization and enhancements to assure plant design basis is satisfied.

IDENTIFICATION OF OCCURRENCE Discovery Date: September 20, 1995 Report Date: December 1, 1995 CONDITIONS PRIOR TO OCCURRENCE Unit Mode % Reactor Power 1 Defueled 0 2 5 0 DESCRIPTION OF OCCURRENCE On August 31, 1995, during a system readiness review* meeting, the implementation of Technical Specification (TS) 6.8.4a was questioned. The TS states, in part:
" a. Primary Coolant Sources Outside Containment A program to reduce leakage from those portions of systems outside containment that could contain highly radioactive fluids during a serious transient or accident to as low as practical levels. The systems include (recirculation spray, safety injection, chemical and volume control, gas stripper, recombiners, ... ).The program shall include the following: *
(i) Preventive maintenance and periodic visual inspection requirements, and
.(ii) Integrated leak test requirements for each system at refueling cycle :intervals or less."

TEXT CONTINUATION FACILITY NAME 111 DOCKET LER NUMBER 161 PAGE 131 YEAR I SEQUENTIAL NUMBER I REVISION NUMBER Salem Generating Station - Unit 1 05000272 3 OF 4 95 -- 028 -- 000 TEXT (If more space is required, use additional copies of NRC Form 366AJ I 171 An investigation into this concern revealed that these requirements were incorporated in the TS in response to NUREG-0578, "TMI Lessons Learned."
The TS 6.8.4a requirements for "preventive maintenance and periodic visual inspection requirements" are in place, but they are not controlled as a single program. Daily leak reduction activities are performed by the Operations Department. System leak tests have been performed after every refueling outage by the In-Service Testing organization.
- However, it has been determined that these leak reduction activities do riot comprise a well-defined program for the following reasons:
- 1. There is no specific organization that monitors and controls the leak reduction program and ensures that is kept in compliance with TS requirements.
- 2. The once-per-refueling cycle system leak test procedures do not reference TS 6.8.4a. The daily leak reduction activities are performed to reduce liquid radwaste, not to comply with TS 6.8.4a.
- 3. The leak monitoring program does not compare leak rate data with the licensing basis leak rate (0.008gpm) assumed in the UFSAR.
- 4. The program does not require the eve, SI and RHR pumps to be in operation to make observations on pump seal leakage.
APPARENT CAUSE OF OCCURRENCE The cause of this event has been attributed to management/QA deficiency,. in that no one individual or organization was a,ssigned lead responsibility for compliance with the administrative requirements of TS 6.8.4a.
- PRIOR SIMILAR OCCURRENCES Previous similar occurrences of failure to meet Technical Specification Section 6 administrative requirements include LER 272/94-016 regarding inadequate control room staffing and LER 272/91-011 regarding an unlocked/unguarded door to a high radiation area.
SAFETY SIGNIFICANCE The intent of TS 6.8.4a is to assure that leakage from the Eees cold leg recirculation loop into the auxiliary building during a postulated design basis accident would not result in violations of GDC 19 and 10CFRlOO limits. One known example of safety significant leak from systems covered by this TS has been positive displacement charging pump (PDP) packing leaks. The leak rate for the operating PDP has been greater than the leak rate assumed in the UFSAR. LER 272/95-027 issued on 11/25/95 provides further information on this issue. This program deficiency resulted in a missed opportunity to identify and minimize the PDP packing leaks.
