s Surnary of U-l Operating Experience January 1988 1/1 Unit began this reporting period at 100% reactor' power and (860 MWe).

At 2200, power was reduced to 840 MWe to allow Fuel Management to conduct moderator temperature coefficient determination.

1/3 At 1555, returned to full reactor power.

1/21 At 0600, reduced power to 840 MWe to remove moisture separator reheaters from service.

This was to prevent further damage to No. 11 MSR tube bundles and/or divider plates.

1/29 At 2146, commenced power reduction to repair steam leak at high pressure turbine extraction pipe.

1/30 At 0222, Unit was removed from main grid.

1/31 At 0400, paralleled Unit to main grid.

The Unit ended this reporting period at 95% power and escalating to 974.

Name of facility: Calvert Cliffs Nuclear Power Plant, Unit No. 1.

2.

Scheduled date for next refueling shutdown: April 8, 1988 3.

Scheduled date for restart following refueling: May 26, 1988 4.

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

Resumption of operation after refueling will require changes to Technical Specifications. The changes will be such as to allow operation of the plant with a fresh reload batch and reshuffled core for unit l's first 24 month cycle.

5.

Scheduled date(s) for submitting proposed licensing action and supporting information.

February 17, 1988 6.

Important licensing considerations associated with the refueling.

Reload fuel will be similar to that reload fuel inserted into Calvert Cliffs Unit 2 Eighth cycle except for four lead demonstration arsemblies manufactured by Advanced Nuclear Fuels.

7.

The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool.

(a) 217 (b) 1138 Spent fuel pools are common to Units 1 and 2.

8.

(a) The present licensed spent fuel pool storage capacity, and (b) the size of any increase in licensed storage capacity that has been requested or is planned, in number of fuel assemblies.

(a) 1830 (b) 0 i

9.

The projected date of the last refueling that can be oischarged to the j

Spent Fuel Pool assuming the present licensed capacity and maintaining 1

Corrective Action:

1. Maintenance electricians' review of events Iceding to trip.
2. Design review of coordination of breaker / fuse timing.
3. Increase the use of special procedures for complex trouble-shooting.

Summary of U-2 Operating Experience January 1988 1/1 Unit began this reporting period at full power (860 MWe).

f 1/7 At 1500, reduced reactor power to 90% to remove No. 26 Circulating Water Pump from service.

A faulty connection at temperature element for thrust bearing gave the computer a false signal, the high temperature caused the Centrol Room to stop tha pump.

At 1800, returned to full reactor power.

1/22 At 1000, reactor trip on low steam generator water level.

This was induced by the opening of ekt bkr 52-20429 due to a fault in the computer invertor's dummy load test.

At 2300, reactor critical.

i 1/23 At 0147, Unit paralleled to Main Grid.

At 1200, Unit at full reactor power.

1/31 Unit end this cycle at full reactor power.
