1-5-87 At 0740 hours0.00856 days <br />0.206 hours <br />0.00122 weeks <br />2.8157e-4 months <br /> a 30 day Limiting Con dition for Operation (LCO) was entered when a reactor water con ductivity element transmitter was removed from service for work on a leaking sample rock.

A collector tank fitting was tightened and the transmitter was returne d to service.

The LCO was exited at 1937 hours0.0224 days <br />0.538 hours <br />0.0032 weeks <br />7.370285e-4 months <br /> on 1-8-87 At 1055 hours0.0122 days <br />0.293 hours <br />0.00174 weeks <br />4.014275e-4 months <br /> a 7 day LCO was entered when the Electric Fire Pump (IP-048) was removed from service for repairs to a sticking supply breaker.

The breaker was cleaned and l u br i ca te d.

The pump was returned to service at 1014 hours0.0117 days <br />0.282 hours <br />0.00168 weeks <br />3.85827e-4 months <br /> on 1-6-87 thus exiting the LCO.

At 1530 hours0.0177 days <br />0.425 hours <br />0.00253 weeks <br />5.82165e-4 months <br /> a 14 day LCO was entered when the

'A' Diesel Generator preaction sprinkler system f ailed to operate dur i ng surve i l lance testing.

A defective diaphragm bypass valve was replaced, the system returned to service, en d the LCO terminated at 1729 hours0.02 days <br />0.48 hours <br />0.00286 weeks <br />6.578845e-4 months <br /> on 1-16-87.

'B' Recirculation M G-S e t tripped due to problems wIth the

'B' Recirc Lube Oil Pump breaker.

This placed the plant in single loop operation (SLO).

Repairs were ma de to the breaker cubicle and the

'B' Recirculation pump was returne d to service et 1340 hours0.0155 days <br />0.372 hours <br />0.00222 weeks <br />5.0987e-4 months <br />.

As require d by Techntesi Specifications an alternate sample path was established.

The LCO was exite d at 17'.1 hoers on 1-23-87 wIth the element being returned to ser vice.

'A' Stan dby F 7 lier Unit (SFU) was removed f rom service for annuel Inst ument cellbr971on.

This placed the plant in two (2) separate 7 day LCOs.

Following successful completion of the respective systems Insteument calibration, both systems were returred to service at 1904 Sours on 1-29-87 The LCOs were terminated at this time.
