The NRC inspectors also visually inspected safety components for leakage, physical damage, and other impairments that could prevent them from performing their designed function Selected NRC inspector observations are discussed below:

Material conditions within the plant were good with continuing improvements evident during the inspection period. Licensee management has formed an inspection team which routinely conducts housekeeping tour No violations or deviations were identifie . MonthlySurveillanceObservation(617261 The NRC inspectors observed selected portions of the performance of surveillance testing and/or reviewed completed surveillance test procedures to verify that surveillance activities were performed in accordance with Technical Specification (TS) requirements and administrative procedures. The NRC inspectors considered the following elements while inspecting surveillance activities:

,

o Testing was being accomplished by qualified personnel in accordance with an approved procedure, o The surveillance procedure conformed to TS requirements, o Required test instrumentation was calibrated o TS limiting conditions for operation (LCOs) weh satisfied, o Test data was accurate and complete. Where appropriate, the NRC inspectors perfonned independent calculations of selected test data to verify accuracy, o The performance of the surveillaace procedure conformed to applicable administrative procedure o The surveillance was performed within the required frequency and the test results met the required limit Surveillances witnessed and/or reviewed by the NRC inspectors are listed below:

<

conducted in accordance with approved procedures, TS, and applicable industry codes and standards. The following elements were considered by the NRC inspectors during the obse'?ation and/or review of the maintenance activi:ies:

1988, the NRC inspector reviewed WR 02842-88. The shift On July 17,(SS) was also reviewing the WR prior to giving permission to supervisor start. The NRC inspector observed that for the low pressure hydro, Valves BG V-363 and BG V-364 would be ope The valves are on a system connected to the reactor coolant system, in a drain line outside of containment, and between Containment Penetration 23 and Valve BG HV-8152. Both the outboard containment isolation valve (BGHV-8152)andtheinboardcontainmentisolationvalve(BGHV-8160)

are listed in the TS as Phase A containment isolation valves. When questioned as to the operability of Penetration 23 the SS stated that BG HV-8160 would be maintained closed during the hydro. However, after dir.cussions with the NRC inspector, the SS realized that maintaining BG HV-8160 closed wnuld at completely satisfy the TS and the SS subsequently ensured that performance of the WR would not violate T No violations or deviations were identifie . Onsite Event Followup (92700)

The NRC inspectors perfonned onsite followup of nonemergency events that occurred during this report period. The NRC inspectors reviewed control room logs and discussed the events with cognizant personnel. The NRC inspectors verified that the licensee had responded to the events in accordance with procedures and had notified the NRC and other agencies as required in a timely fashion. The events that occurreo during this report period are listed in the table below. The NRC inspectors will review the

~

licensee event reports for these events and will report ary findings in a subsequent NRC inspection repor Date Event * Plent Status, Cause r 07/11/88 CRVIS Mode 1 Broken tape on GK AI-2 (100 percent)

During this inspection period, the NRC inspectors performed followup on Wolf Creek LER The LERs were reviewed to ensure:

o Corrective action stated in the report has been properly completed or work is in progress, o Response to the event was adequate, o Response to the event met license conditions, commitments, or other applicable regulatory requirements.-

o The information contained in the report satisfied applicable reporting requirements, o Generic issues were identifie The LERs discussed below were reviewed and closed:

Change MA 86-0664 to prevent an accident signal from the wide range l gas monitors being sent to the p3rticulate and iodine monitors. The

change was noted to have been incorporated during review of STS

CH-014, Revision 2. A memo was also sent to the chemistry

i-8-o 87-29, "Required Testing Deleted From Surveillance Procedures."

Procedure ADM 07-100, Revision 32, "Preparation, Review, Approval, and Distribution of WCGS Procedures," has been revised to require that the effects on TS surveillance requirements be considered when procedure changes are made. This revision continues to be included in ADM 07-100, Revision 3 o 87-33, "Innperable Containment Isolation Valve Caused by Incomplete Retesting Following Maintenance Activity." Temporary Procedure Change NI 87-199 was issued to change Procedure MGE E00P-02, Revision 5, "Limitorque Adjustments, Repair, and Service." The changa established controls for performance of a local leak rate test prior to and after limit switch adjusument, o 87-34, "Failure to Effectively Communicate Allows An Open Door Creating a Control Room Pressure Boundary Breach." Temporary Procedure Change NI 87-195 was issued to ALR 00-063A, Revision 3

"Control Room Ventilation Isolation Signal (CP.VIS)." The change requires operators to ensure that certain control room fire dcors are shut should a CRVIS alarm be received in the control room. Signs have also been posted on the doors stating that control room oersonnel must be contacted prior to performing work that requires propping the doors ope o 87-36, "Inadvertent Release Of a Secondary Liquid Waste Monitor Tank (SLWMT) Without Prior Sampling Caused By Procedure Inadequacy."

Temporary Procedure Change NNSR 87-040 was issued for Procedure SYS HF-200, Revision 3. "Secondary Liquid Waste System Operations." This change provided additional isolation requirements for the SLWMT not being discharge . Engineered Safety Features (ESF) Walkdown (71710)

The NRC inspectors verified the operability of an ESF system by walking down selected accessible portions of the system. The NRC inspectors verified that valves and electrical circuit breakers were in the required position, power was available, and valves were locked where required. The i

NRC inspectors also inspected system components for damage or other

'

conditions that could degrade system performanc The ESF system walked down during this inspection period and the documents utilized by the NRC inspectors during the walkdown are listed below:

is being complied with by direct observation of licensee facilities and security personne '

The NRC inspectors verified by observation of randomly selected activities that search equipment was operable, the protected area barriers and vital ~

area barriers were well maintained, access control procedures were followed, and appropriate compensatory measures were followed when equipment is inoperabl No violations or deviations were identifie . RadiologicalProtection(71709)

By performing the following activities, the NRC inspectors verified that radiologically related activities were controlled in accordance with the licensee's procedures and regulatory requirements: *
