SUMMARY

OF UNIT 1 OPRRATING EXPERIENCE Unit 1 began the month shutdown for Cycle 9

Refueling Outage.

Delays to the critical path included MOV-651, (Shutdown Cooling Return Header Isolation Valve), Electrical Penetrations and #12A Safety Inspection Tank Level Transmitter.

Unit 1 ended the month in Hot Standby, awaiting criticality.

i Main generator breaker closure is expected July 3.

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

2.

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 thereaf ter 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 higher enriched (4.3%) reload batch and reshuffled core for Unit l's next 24 month cycle.

• 5.

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

June 9, 1988 * ( enrichment submittal )

Febuary 15, 1990 ( reload submittal )

6.

Important licensing considerations associated with the refueling.

Reload fuel will be similar to that reload fuel inserted into Calvert Cliffs Unit 1 tenth Cycle except for the higher enrichment (up to 5.0%)

• 7.

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

(a) 217 (b) 1331

• 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 2

9.

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE Unit 2 began the month at full power (825 MWE).

Power was reduced temporarily for condenser waterbox cleaning on June 23 I

and 24 when low oxygen concentration and high temperatures,in the Bay caused a fish kill (predominantly hogchokers).

Unit 2 ended the month at 100%

power.

Maximum 100%

power output decreased from 860 (6/1) to 845 (6/22) due to higher ambient condenser cooling water inlet temperatures.
