SUMMARY

OF OPERATING EXPERIENCE 1-1 At the beginning of the report period the plant was operating at 244 Mwe.

1-5 A power increase was begun.

1-6 The plant was operating at 474 MWe at 1327 hours0.0154 days <br />0.369 hours <br />0.00219 weeks <br />5.049235e-4 months <br />.

1-7 During normal operation, an offgas stack high/ low flow alarm was received.

The cause was a frozen sample return line.

ETSV Report 82-1 1-8 During surveillance testing, turbine building main steam supply line area high temperature switch TIS 4477, Subchannel B, was found to have a nonconservative out of specification setpoint.

R0 Report 82-1 1-9 Plant load was reduced to allow control rod withdrawals to be performed.

1-10 A load increase was begun.

1-11 The plant was operating at 486 MWe at 1430 hours0.0166 days <br />0.397 hours <br />0.00236 weeks <br />5.44115e-4 months <br />.

1-12 During surveillance testing, RCIC steam supply high flow PDIS 2441 and PDIS 2442 were found to have out of tolerance setpoints.

R0 Report Pending 1-13 During surveillance testing, reactor low pressure (core spray and RHR valve opening permissive) switch PS 4529 was found to have an out of tolerance setpoint.

R0 Report Pending 1-14 During normal operation torus level recorder LR 4385 was found indicating downscale.

R0 Report Pending During normal operation the "B" containment oxygen analyzer was declared inoperabl e. The redundant analyzer was out of service for design change work.

R0 Report Pending 1-15 During normal operation, offgas stack sample pump 1P-247A was found inoperable. The redundant sample pump had been found inoperable earlier.

ETSV Report 82-2

SUMMARY

OF OPERATING EXPERIENCE During surveillance testing, drywell high pressure (RPS) switch PS 4315B, was found to have an out of tolerance setpoint.

R0 Report Pending 1-18 A power increase was begun.

1-19 The plant was operating at 533 MWe at 1500 hours0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.7075e-4 months <br />. A RHRSW system snubber and the valve yoke on CV 2037 were found broken. An evaluation was begun.

1-21 The LPCI system was declared inoperable pending an engineering evaluation as a result of a stress analysis (which was conducted after snubber GBC SS-56 was found broken) which concluded a section of RHR piping may have been overstressed.

R0 Report Pending 1-22 A control rod sequence exchange was completed. A power increase was begun.

1-24 Engineering evaluations, hydrostatic testing, NDT, and operability testing were completed on the RHRSW and LPCI systems and these systems were declare 1 operable.

5 1-25 The plant was operating at 526 MWe at 1440 hours0.0167 days <br />0.4 hours <br />0.00238 weeks <br />5.4792e-4 months <br />.

1-30 Power was reduced to allow repair work to be completed on the "A" main condenser.ai r ejector. A power increase was begun.

1-31 The plant was operating at 537 MWe at 2230 hours0.0258 days <br />0.619 hours <br />0.00369 weeks <br />8.48515e-4 months <br />.
