Two Maintenance Surveillance Tests (MSTs)which verify operability of the Nuclear Instrumentation Source Range Monitors and are required to satisfy TS 4.9.2.c were not performed prior to entering Mode 6, thereby, violating technical specification requirements.

On August 15, 1988, the Maintenance Foreman and Operations Shift Foreman discussed the requirements for running these surveillance tests and agreed they should have been performed prior to entry into Mode 6.By 1645 hours0.019 days <br />0.457 hours <br />0.00272 weeks <br />6.259225e-4 months <br />, both MSTs had been performed satisfactorily.

The cause of the event was deficient planning and scheduling.

These two surveillance tests had been unscheduled while the plant was operating due to the tests being Mode 6 requirements.

Corrective action includes automatically scheduling all surveillance tests, regardless of mode requirement or frequency, and printing schedule dates for routine reports to ensure the requirements are visible to all personnel responsible for performing surveillance tests.NAC Fotm 355 (DS3)

TS 4.0.4 prohibits entry into an operational mode unless the surveillance requirements associated with the Limiting Condition of Operation have been performed within the specified interval.or unless otherwise specified.

Maintenance Surveillance Test (MST)-I0169, Nuclear Instrumentation Source Range N31 Operability Test, and MST-I0170, Nuclear Instrumentation Source Range N32 Operability Test, satisfy TS 4.9.2.c.At 2259 hours0.0261 days <br />0.628 hours <br />0.00374 weeks <br />8.595495e-4 months <br />, the plant entered Mode 6, when the reactor vessel head closure bolts were detensioned.

Surveillance tests, MST-I0169 and MST-I0170 had not been performed as required prior to entering Mode 6, violating TS 4.0;4.At 0730 hours0.00845 days <br />0.203 hours <br />0.00121 weeks <br />2.77765e-4 months <br /> on August 15, 1988, Regulatory Compliance personnel were conducting a review of Mode 6 surveillance requirements.

It was then discovered that these weekly tests had not been performed and the Maintenance Foreman responsible for performing the test was notified.At 1330 hours0.0154 days <br />0.369 hours <br />0.0022 weeks <br />5.06065e-4 months <br />, the Maintenance Foreman and Operations Shift Foreman discussed the requirements for running these surveillance tests and agreed they should have been performed prior to entry into Mode 6.At 1600 hours0.0185 days <br />0.444 hours <br />0.00265 weeks <br />6.088e-4 months <br />, MST-I0169 was completed satisfactorily and at 1645 hours0.019 days <br />0.457 hours <br />0.00272 weeks <br />6.259225e-4 months <br />, MST-I0170 was completed satisfactorily.

CAUSE Surveillance tests with a frequency of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or.greater are automatically scheduled on the Surveillance Test Scheduling System.The surveillance procedure schedule is pr'nted for a routine report based on the frequency of the'test, i.e., if the frequency is weekly, the test will print on the schedule every week.MST-I0169 and MST-I0170 did not schedule automatically because Regulatory Compliance had previously removed'them from the schedule.This was due to the tests being a Mode 6 requirement andrit was undesirable to have those tests print on schedule for the long term the plant was not in Mode 6.Since they did not print out automatically, it was not readily apparent that the tests needed to be performed.

ANALYSIS MST-I0050, Calibration of Nuclear Instrumentation System Source Range N31, had been performed satisfactorily in its entirety on August 7, 1988.This test satisfies the requirements of MST-I0169, therefore, source range monitor N31 was in compliance with the seven day requi.rement of TS 4.9.2.c when the plant entered Mode 6 on August 12, 1988.Source Range Monitor N32 had been tested r NRC FORM See*IB 831 o U.S OPO.1088 082e 538/e55 NRC Form SSSA (883(LICENSEE EVENT REPORT ILER)TEXT CONTINUATION U.S.NUCLEAR REOULATORY COMMISSION APPROVED OMS NO, 3(50&104 EXPIRES;8/31/88 FACILITY NAME l(l DOCKET NUMSER (2)LER NUMBER (Sl PACE (3I Shearon Harris Nuclear Power Plant-Unit One TEXT (//more Afeoe ie eerreirer/.
