OPERATIONAL
SUMMARY
NOVEMBER, 1979
.The unit shutdown which was initiated on October 25, 1979, when Reactor Coolant Pump (RCP) 2-2 tripped L am a blown fut i, continued until 1811 hours0.021 days <br />0.503 hours <br />0.00299 weeks <br />6.890855e-4 months <br /> on November 20, 1979, when the turbine-generator was synchronized. Below is a list of the major work items performed during the outage:
- 1. All four RCP seals were replaced.
- 2. A new expansion joint for 1-4-2 heater extraction was rewelded.
- 3. A design change to the Couch relays in the RCP starting interlock circuits was made. This initiated a similar change .in sixteen safety related cir-cuits.
- 4. NI-3 was pulled and a new detector was installed. A new section of cable between the containment penetration and the NI-1 pre-amp was installed.
1
- 5. Several pipe restraints were modified as a result of IE Bulletin 79-14 findings.
11/20/79 - 11/21/79 The unit returned on line at 1811 hours0.021 days <br />0.503 hours <br />0.00299 weeks <br />6.890855e-4 months <br /> on November 20, 1979, and reactor power was increased to 81% of full power with generator gross load at 760 MWe on November 21, 1979.
11/22/79 Reactor Coolant System (RCS) flow inidcation was determined to be less than required by Technical Specification 3.2.5 at 0300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br />. Reactor power was decreased to 73% at which point RCS flow indication was back within allowable limits. At 0400 hours0.00463 days <br />0.111 hours <br />6.613757e-4 weeks <br />1.522e-4 months <br /> generator gross load was 684 MPe.
11/23/79 - 11/25/79 Reactor power was maintained lat approximately 73% until 0620 hours0.00718 days <br />0.172 hours <br />0.00103 weeks <br />2.3591e-4 months <br /> on November 25, 1979, when RCS flow indication was again determined to be less than that required by Tec'..nical Specifi-cations. Reactor power was decreased to 67% at which point the RCS flow indication was again back within tolerance. The cause of the low flow indication is still being investigated.
11/26/79 Reactor power was maintained at approximately 69% of full power. At 2145 hours0.0248 days <br />0.596 hours <br />0.00355 weeks <br />8.161725e-4 months <br /> on November 26, 1979, RCP 1-2 was manu-ally tripped due to a lower motor bearing low oil level alarm.
11/27/79 - 11/28/79_ The unit remained at approximately 68% of full power with generator gross load of 635 MWe until 0645 hours0.00747 days <br />0.179 hours <br />0.00107 weeks <br />2.454225e-4 months <br /> on November 28, 1979, when it was determined that the power range nuclear instrumentation (NIs) were reading slightly greater than 2%
below the calculated heat balance. Reactor power was reduced to 50% to bring the in tolerance and to run another heat balance to get the n - in tolerance.
