6/2 Began CpC' verification test and COLSS initialization.
6/5 Completed Mode change checklist for Mode 1, entered Mode 1.
6/7 1327 - Completed shell warming for the turbine, closed main steam stop valve #2 bypass.
6/8 Continued turbine generator startup.
6/8. 1532 - Turbine at rated speed of 1800 rpm.
6/8 1650 - Turbine was at 1800 rpm for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and 20 minutes and then tripped on Hi vibration on the #8 bearing.
6/9 1150 - Turbine at rated soeed of'1800 rom.
6/9 1433 - Tripoed. Main Turbine manually due to Hi vibration on
- 7 bearing.
6/10 2226 - Approximately 20 min after the main generator was loaded CPC D DNBR started cycling causing a channel D trip. During.the investigation, the main' turbine had to be tricoed on high vibration. When the turbine was unloaded and tricoed, the DNBR cycling on CPC D
. stopped.
6/10 1149 ~ A; set speed of 1800 rpm on Turbine.

6/14 1156 - FWpT "B" tripoed on low suction pressure, tricoed Main Turbine, Reactor tripped on high Local Power Density (LpD). NO7E: On further investigation it was found the reactor trio was due-to hi oressurizer cressure.
6/16 1323 - Criticality achieved on Unit i reactor.
6/17 Main turbine generator trio caused by oscillations in the feedwater control system. This caused a main feedwater pumo tria.
6/18 1215 - Lowered turbine generator load down to 101 MW to cycle Atmospheric dump valve ADV SGA-184 6/18 1259 - Raised turbine generator load to 175 MW SGA-184 cycled 5 times (sat).
6/22 1611 - Increased surveillance frecuency on CEA positions oue to reouirements of T.S. 4.1.3.6 with the PDIL auctioneer circuit inocerable.
6/23 Inserted Group 5 rods to 12" withdrawn for Rx Engineering in preparation for delta temperature and delta power testino.
6/24 1404 - Tricoed turbine, began reducing power to 13% cower Note: The turbine shutdown was required because pressure point isolation valves MTN-V243 and MTN-V244 were blown off the main steam lines downstream of MTN-UV2002 causing a 1" hole in the steam line.
6/24 1610 - Rx power 11%.
6/25 0250 - Steam line break recaired, reset main turbine, commence:1 chest-warming.
6/25 2338 - Rx cower 14.9%
6/26 1255 - Performed Automatic Economizer /Downcomer feedwater control valve transfer, transferred at 16.5% power.
Initial test results are satisfactory.
6/27 Completed final economizer /downcomer valve testing, returned reactor cower to 19.8% cower.
6/27_1258 - Entered action statement on pressurizer safety valve position indication (3.3.3.6). for removal o? temporary test eouioment, 6/27 1430 - Exit ed action statement for pressurizer safety valve position indication.
6/28 RRS auto CEA insertion and withdrawal were tested satisfactory, (at low rate), following CEDMCS repairs.
6/29 2340 - Rx power 22%
.. +
6/29 0300 - Tavg dropped low due to inadvertant boration of the RCS.
This boration was due to makeup mode selector switch in dilute position causing a boration vice dilution.
Attemoted to duplicate, problem could not be duplicated.
6/30 0356 - COLSS (CMC) ceclared operable 6/30 0430 - Began oower ascension to 30% F.P.
6/30 2206 - Rx at 40% power generator load at 405 MWe.

W The "A" Main Feedwater Pump Mini-Flow Control Valve did not control properly, allowing excessive condensate flow back to.the condenser.
This in conjunction with improper operation of Condensate Pump Mini-Flow Control Valves caused a low suction pressure trip of the "B" Main Feedwater Pumo at 1155. The reactor operators manually i tripped the turbine-generator, started auxiliary feedwater and began manually reducing reactor power by insertion of CEA's attempting to reduce. power to within the capability of the Auxiliary a ~^
feedwater System. At 1156 the reactor tripped on high pressurizer pressure, i . .
i
.Carse of the. trip was improper operation of the "A". Main Feedwater Pump Mini-Flow Control Valve.
