NARRATIVE

SUMMARY

OF l

KNI'HLY OPERATING EXPERIENCE JUNE, 1987 June 1 At 1137 hours0.0132 days 0.316 hours 0.00188 weeks 4.326285e-4 months on the 1st a turbine trip / reactor trip through occurred due to a loss of turbine auto stop oil pressure.

June 2 The reactor was taken critical at 0128 hours0.00148 days 0.0356 hours 2.116402e-4 weeks 4.8704e-5 months on the 2nd l

arv3 was synchronized to the grid at 0316 hours0.00366 days 0.0878 hours 5.224868e-4 weeks 1.20238e-4 months .

i l

l June 3 The Station was in Operational Mode 1 with reactor power l

through at a ncxninal 100 percent and the Reactor Coolant System June 7 at a normal cperating pressure and temperature.

j i

June 8 Began a power reduction at 2015 hours0.0233 days 0.56 hours 0.00333 weeks 7.667075e-4 months due to broken studs-on the

'C' main feedwater regulating valve.

l Stabilized the plant at approximately 30% power at 2115 hours0.0245 days 0.588 hours 0.0035 weeks 8.047575e-4 months .

June 9 At 0305 hours0.00353 days 0.0847 hours 5.042989e-4 weeks 1.160525e-4 months it was discovered that control rods in control Bank D and shutdown Bank B were misaligned. At 1330 hours0.0154 days 0.369 hours 0.0022 weeks 5.06065e-4 months , following restorire all rods to their required alignment and repairs to the 'C' main feedwater regulating valve, power ascension was initiated. At 1343 hours0.0155 days 0.373 hours 0.00222 weeks 5.110115e-4 months a reactor trip occurred on high flux rate. This incident occurred due to drcpped control rods caused by a failed circuit board.

June 10 Began reactor startup at 0915 hours0.0106 days 0.254 hours 0.00151 weeks 3.481575e-4 months and achieved criticality at 0951 hours0.011 days 0.264 hours 0.00157 weeks 3.618555e-4 months . The Unit was synchronized to the grid at 1148 hours0.0133 days 0.319 hours 0.0019 weeks 4.36814e-4 months followed by power ascension l

toward a nominal 100%.

June 11 At 0445 hours0.00515 days 0.124 hours 7.357804e-4 weeks 1.693225e-4 months began a plant shutdown due to potential l

misalignment of control rods H-2 and p-8.

Power I

reduction was halted at 0520 hours0.00602 days 0.144 hours 8.597884e-4 weeks 1.9786e-4 months with reactor power at approximately 70%

. hen control rods H-2 and p-8 w re w

l verified to be within 12 steps of their group demand l

counter. At 0745 hours0.00862 days 0.207 hours 0.00123 weeks 2.834725e-4 months , power ascension toward 100% was f

begun.

j June 12

'Ihe Station was in Operational Mode 1 with the reactor thrcugh power at a nominal 100 percent and the Reactor Coolant l

June 25 System at a normal cperating pressure and temperature.

June 26 At 2200 hours0.0255 days 0.611 hours 0.00364 weeks 8.371e-4 months on the 26th, Conpany System requested a i

thrcugh power reduction to 50%.

Began power ascension toward June 30 100% at 0400 hours0.00463 days 0.111 hours 6.613757e-4 weeks 1.522e-4 months on the 29th.. _ _ _ - _ _ _ _ _ _ _ _ _
