SUMMARY

OF MONTHLY OPERATING EXPERIENCE - AUGUST, 1983 August 1 The station was in operational mode 6 except that no fuel through was in the reactor vessel. The replacement of the control rod August 6 guide tube split pins was in progress. All fuel was in the spent fuel pool and all reactor coolant loops were isolated and drained. All steam generators were drained on both primary and secondary sides. The spent fuel pool cooling and purification system was controlling decay heat.

August 7 The split pin replacement wa-completed on the 7th. On the 9th, through the secondary side of the IB Steam Generator was hydro tested August 13 following the completion of tube plugging' On the 10th, the lA Reactor Coolant Loop was filled and v,ented, as was the 1B Loop on the 12th.

Both loops were returned to service.

Fuel loading began at 0204 hours0.00236 days <br />0.0567 hours <br />3.373016e-4 weeks <br />7.7622e-5 months <br /> on the 13th.

August 14 The station was in operational mode 6 with fuel loading in progress when a cable broke on the fuel upender at 0945 hours0.0109 days <br />0.263 hours <br />0.00156 weeks <br />3.595725e-4 months <br />. The fuel transfer canal was isolated and drained to allow the upender cable to be replaced.

August 15 Following repairs to the fuel upender, the fuel transfer canal was unisolated then reflooded, and fuel loading resumed at 0615 hours0.00712 days <br />0.171 hours <br />0.00102 weeks <br />2.340075e-4 months <br />.

August 16 Fuel loading was completed at 0141 hours0.00163 days <br />0.0392 hours <br />2.331349e-4 weeks <br />5.36505e-5 months <br />.

August 17 Work began on installing the upper internals in the reactor vessel.

through It was discovered that a fuel assembly, K-2, had been damaged August 25 while reloading the core. At 1949 hours0.0226 days <br />0.541 hours <br />0.00322 weeks <br />7.415945e-4 months <br /> on the 25th, movement of 67 fuel assemblies frca the reactor vessel to the spent fuel pool was begun in order to inspect the damaged assembly.

The 1C Reactor Coolant Loop was filled and vented on the 24th.

August 26 The station was in operational mode 6, refueling. At 2315 hours0.0268 days <br />0.643 hours <br />0.00383 weeks <br />8.808575e-4 months <br /> the movement of fuel was completed. The damaged assembly, K-2, was the last one removed from the reactor vessel.

August 27 The station was in operational mode 6 with RCS temperature and through pressure at ambient conditions.

Fuel reloading was started at August 31 0720 hours0.00833 days <br />0.2 hours <br />0.00119 weeks <br />2.7396e-4 months <br /> on the 31st.
