An unusual event was declared and a controlled power reduction initiated.

At 2230 hours0.0258 days <br />0.619 hours <br />0.00369 weeks <br />8.48515e-4 months <br /> repair and testing of "B" side ADS were completed cancelling the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> LC0 and unusual event. 7 day LC0 on HPCI inoperability (begun 2-29-84) continued.

03-04-84 Increased reactor power after completion of repairs and tests at' 0302 hours0.0035 days <br />0.0839 hours <br />4.993386e-4 weeks <br />1.14911e-4 months <br />.

03-05-84 Cummulative exposure of certain fuel bundle nodes exceeded the exposure of current MAPLHGR curves in T.S. Section 3.12. A Technical Specification change (RTS-163) is pending.

03-06-84 Repairs and testing of HPCI completed. HPCI declared operable cancelling 7 day LCO at 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br />.

piping had a momentary decrease in pressure,-causing an RHR low pressure alarm.
