Auaust 1988 Unit 1 began the month at full power (100%), 845 We Net. 'Ihe mav!== operatirrj output decreased to a minilman of J70 We Net.

On 8/13/88, #11 Feed Punp tripped. '1he pung was reset and returned to servloe.

Punp investigation required that we operate at 70% power. On 08/17/88, we increased power to 100%. On 08/23/88, at 1115, power was reduced to replace the

1. 11 Feed Puup casing level switch. Power was then increased to 100%. On 08/24/88 ac 2330, the unit tripped on high S/G level (#12) when the Feedwater Regulating Valve control air supply line sheared off. On 08/25/88 at 1607, we conducted a normal reactor / unit start-up and escalation to power. 'Ihe unit was paralleled to the grid at 2135 on 08/25/88. Escalation to 100% was delayed at 30% for feedwater chemistry and again 0 70% due to high vibration on #4 Main Turbine Bearing.

100% power was roached 9 1100 on 08/26/88.

'Ihe unit ended this reporting period 0100% power on 08/31/88.

Scheduled date for next refueling shutdown: March 31, 1990 3.

Scheduled date for restart following refueling: May 15,1990 4.

Will refueling or resumption of operation thereafter require a Technical Specification change or other license amendment?

Resumption of operation after refuelin6 will require changes to Technteni Specifications. The changes will be such as to allow operation of the plant with a higher enriched (4.31) reload batch and reshuffled core for Unit l's next 24 month cyclo 5.

6.

Important licensing considerations associated with the refueling.

Reload fuel will be similar to reload fuel inserted into the provious cycle except for the higher enrichment ( 4.31 ).
