• WOLF CREEK GENERATING STATION

. PRIMARY COOLANT SOURCES OUTSIDE CONTAINMENT This-defines Kansas Gas and Electric's 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. This program is in support of NUREGs 0737,_0881, and 0830 and will fulfill the requirements of the Wolf Creek- Generating Station FSAR and Technical Specifications. .The systems considered include the recirculation portion of the Contain-i ment Spray- System, Safety Injection -System, Chemical and Volume Control System, Residual Heat Removal System c,d Nuclear Sampling System (PASS only). The program is as follows:

1. General ~ Practical Leak Reduction Measures The Operations Department will develop procedures which will govern the monitoring of specific systems to main-tain as low a leak rate as practical, and make periodic inspections of affected systems.

Maintenance as directed by W' o rk Requests, will perform repair / rework on all components as needed to correct leaks _ as they are detected.

2. Periodic Visual Inspection In' accordance with Wolf Creek Generating Station (WCGS)

Administrative - Procedures, the Operations Department is -

tasked with the responsibility of _ inspecting all the -

recirculation portions of the containment Spray System, Safety Injection System, Chemical and Volume Control System, Residual Heat' Removal System and Nuclear Sampling System (PASS'only) outside of containment. -Operation's Personnel will inspect the above named systems including vent valves, drain valves, relief-valves, sample valves and. flushing valves, as well as the in-line . valves, piping and pumps. The Operations Department will 'make this inspection prior to initial f uel load and once between each refueling. Leak rates will be determined and leaks reduced to as low a level as practical. Work requests will be generated by the Operations Department for maintenance / repair / rework to correct leaks as they are found. A one-time-report will. be submitted to the NRC prior to initial fuel load.

In addition, .the normal duties and responsibilities of the Operations Department as described in WCGS ADM 02-010 will include walkdown and visual inspection of accessible systems. Identification and correction of leakage is one of the criteria specified for these walkdowns.

WCGS Primary Coolant Sources Outside Containment Page 2 Housekeeping is also carried out by a WCGS Administrative

' Procedure 01-034 which requires a daily walkdown to check for cleanliness, leaks and spills. WCGS Administrative Procedure 01-034, Paragraph 6.1.3 directs that any spills be promptly contr olled and cleaned up. WCGS ADM 03-852 Paragraph 6.2 provides the guidelines for radioactive -

spills.

3 Additional Programs Resulting in Detection and Redaction of Leakage WCGS has an established Managed Maintenance Program which is documented by WCGS ADM 08-202. This progran includes generic preventive maintenance activities based on experience, engineering judgement, inspection , testing and replacement of items which have a specific lifetime such as weer rings, bearings, seals and packing.

WCGS is also committed to ASME Section XI Inservice Inspection Program using the ASME Code 1980 and winter 1981 Addition.
