8/10/80 REFUELING INFORMATION RE0 VEST

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

2. Scheduled date for next Refueling Shutdown: October 17, 1980

3. Scheduled date for restart following refueling: Novernber 27, 1980

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.

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

August 29, 1980

6. Important licensing considerations associated with the refueling.

Reload fuel will be similar to that reload fuel inserted into the previous cycle.

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

(a) 217 (b) 364 Soent Fuel Pools are common to Units 1 & 2

8. The present licensed spent fuel pool storage capacity and the size of any increase in licensed storage capacity that has been requested ~

or is planned, in number of fuel assemblies.

1056 Licensed 728 Currently Installed 774 Licensed Addition is Planned

9. The projected date of the last refueling that can be discharged to the Spent Fuel Pool assuming the present licensed capacity, October, 1983

StFMARY OF U? LIT 1 OPERATIrlG EXPEPIEf!CE - JULY 1980 7/1 At the beoinnino of this reportina period Unit I was operating at 850 !Ye with the reactor at 100% nower.

7/3 At 0200 load was decreased to 610 PMe to clean condenser water boxes. Load was increased to capacity (850 MWe) at 1800.

7/5 At 0500 load was reduced to 690 MWe to investigate saltwater leakage into the main condenser.

7/6 After plugging one condenser tube resumed full load operation (850 fNe) at 1000.

7/8 At 0350 load was reduced to 660 MWe to investigate saltwater leakage into the main condenser.

7/9 Increased load to capacity (840 P!e) at 0800 after pluoqing one condenser tube. At 1600 load was reduced to 605 MWe to investiaate saltwater leakage into the main condenser.

7/11 After pluggina four condenser tubes resumed full load operation (345 !?!e) at 0030. At 1200 load was reduced to 605 fele to investigate saltwater leakace into the main condenser. Increased load to capacity (840 M!e) at 2210 afte plugging one condenser tube.

l 7/12 At 2100 load was reduced to 725 ! ale to investigate saltwater leakage into the main condenser.

7/13 After pluoping one condenser tube resumed full load operation (840 !*4e) at 0750.

7/14 At 1130 load was decreased to 780 f4!e for troubleshooting an electrical problem with #11 Main Circulating Water Pump.

Resumed full 'oad operation (850 FNe) at 1600.

SUMMARY

OF U!!IT 1 OPEPATI!!G EX? ERIE!!CE - JULY 1980 7/17 At 0005 load was decreased to 740 MWe to clean condenser water-boxes. Increased load to 850 MWe at 0730. At 2250 load was reduced to 740 MUe to investigate saltwater leakage into the main condenser.

7/18 Increased load to capacity (830 MWe) at 2230 a'ter plugging one condenser tube.

7/24 At 0140 load was reduced to 740 MWe to investigate saltwater leakage into the main condenser. Load was increased to 850 MWe at 0610 when indications of saltwater leakage disappeared.

7/26 At 0300 load was reduced to 715 MWe to investigate saltwater leakage into the main condenser. After olugging one condenser tube resumed full load operation (840 MWe) at 1300.

7/27 At 0300 load was reduced to 715 MWe to investigate saltwater leakage into the main condenser. Load was increased to 845 MWe at 1600 when indications of saltwater leakage disappeared.

7/30 At 2040 load was reduced to 730 "We to investigate saltwater leakage into the main condenser.

7/31 Load was increased to 845 MWe at 0300 when indications of saltwater leakage disappeared. At the end of this reporting period Unit I was operating at 845 MWe with the reactor at 100% power.
