ABSTRACT The plant was operating in Mode 1 at 50 percent Reactor power on June 30, 1987. General Procedure (GP)-005, Power Operation, requires a heat balance to be completed at 50 percent power prior to increasing power to 100 percent.

The on-shift crew reviewed Operations Surveillance Test (OST)-1004, Power Range Heat Balance, which is to be performed every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, to see when the last calorimetric was performed. During the review, at 2120 hours0.0245 days <br />0.589 hours <br />0.00351 weeks <br />8.0666e-4 months <br />, it was found a calorimetric had last been perfornied via OST-1004 on June 29 at 0750 hours0.00868 days <br />0.208 hours <br />0.00124 weeks <br />2.85375e-4 months <br />, and it was determined that the surveillance interval had been exceeded. A calorimetric was then immediately initiated and successfully completed at 2210 hours0.0256 days <br />0.614 hours <br />0.00365 weeks <br />8.40905e-4 months <br />, exceeding the maximum time interval by approximately 8 hours.

No safety consequences resulted from this event as'he Nuclear Instrumentation agreed with the calorimetric when performed.

This event is being reported under 10CFR50.73(a)(2)(B) as a violation of Technical Specification 4.3.1.1 Table 4.3-1.

DESCRIPTION:

The plant was operating in Mode 1 at SO percent reactor power on June 30, 1987. Plant operators were preparing to increase reactor power to 100 percent. General Procedure (GP)-005, Power Operation (Mode 2 to Mode 1),

requires a heat balance to be performed at approximately SO percent power prior to increasing power to 100 percent. The heat balance is required only if the turbine was shut down for longer than with 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The calorimetric data the power range nuclear from the heat balance is used for comparison instruments to ensure the accuracy of the power range instrumentation.

Technical. Specification 4.3.1.1 Table 4.3-1 requires a daily surveillance test be performed to compare power range nuclear instruments to a calorimetric.

This is completed per Operations Surveillance Test (OST)-1004, Power Range Heat Balance.

When operations personnel reached the step in GP-005 which requixes the calorimetric be performed, they began a review of OST-1004 to determine if one had been performed in the previous 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />; this would eliminate the need to perform another calorimetric for GP-005. During the review, it was found that the last performance of OST-1004 was on June 29 at 0750 hours0.00868 days <br />0.208 hours <br />0.00124 weeks <br />2.85375e-4 months <br />. At 2120 hours0.0245 days <br />0.589 hours <br />0.00351 weeks <br />8.0666e-4 months <br />, it was determined that the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> surveillance interval, including the 25 percent maximum allowable surveillance extension, had been exceeded. A calorimetric was then immediately initiated and successfully completed at 2210 hours0.0256 days <br />0.614 hours <br />0.00365 weeks <br />8.40905e-4 months <br />, exceeding the maximum time interval by 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> and 20 minutes.

CAUSE The cause of the event was human error. The control room staff inadvertently missed the daily required surveillance as they were waiting for the plant to stabilize in power prior to performing the test. It has been determined that the control room staff is well aware of their daily requirements and that this is an isolated incident.

ANALYSIS No safety consequences resulted from this event as the comparison of the calorimetric to the power range nuclear instruments showed they were within acceptable tolerance.

This event is being reported under 10CFR50.73(a)(2)(B) as a violation of Technical Specification 4.3.1.1 Table 4.3-1.
