SUMMARY

OF UNIT 1 OPERATING EXPERIENCE OCTOBER 1985 10/1 At the beginning of this reporting period, the Unit was in the process of starting up, reactor critical and the main turbine being warmed. At 0011, the Unit was paralleled. Full load operation (852 MWe) was resumed at 1215.

10/2 At 1210, the reactor tripped on loss of load when an erroneous feedwater heater high level signal tripped the main turbine.

10/3 The Unit was paralleled at 0144. Resumed full load operation (849 MWe) at 0615.

10/9 At 2153, the Unit was removed from service to repair the controlled bleed-off line on 11A Reactor Coolant Pump.

10/15 The Unit was paralleled at 1529.

10/16 Resumed full load operation (851 MWe) at 0200.

10/31 At the end of this reporting period, the Unit was at 870 MWe with the reactor at 100% power.

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE OCTOBER 1985 10/1 At the beginning of this reporting period, the Unit was at 844 MWe with the reactor at 100% power.

10/4 Reduced load to 724 MWe at 2200 to clean main condenser waterboxes.

10/5 Resumed full load operation (849 MWe) at 1100. Commenced load reduction to 754 MWe at 1215 due to high circulating water differential temperature and oscillating amperage on 23 circulating water pump.

Resumed fullload operation (851 MWe) at 2110.

10/6 Reduced load to 730 MWe at 2330 to clean main condenser waterboxes.

10/7 Resumed fullload operation (853 MWe) at 0430.

10/18 Commenced shutdown for the sixth scheduled refueling outage at 2035.

10/19 The Unit was removed from the grid at 0142. At 1125, the reactor was shut down.

10/20 The reactor was placed in cold shutdown at 1550.

10/29 Commenced refueling at 1520.

10/31 At the end of this reporting period, the Unit was shut down for its sixth scheduled refueling outage.

November 5,1985 REFUELING INFORMATION REQUEST 1.

Name of Facility: Calvert Cliffs Nuclear Power Plant, Unit No.1 2.

Scheduled date for next Refueling Shutdown: October 25,1986 3.

Scheduled date for restart following refueling: December 27,1986 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.

September 23,1986 6.

Important licensing considerations associated with the refueling.

Reload fuel will be similar to that reload fuelinserted 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) 940 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 9.

The projected date of the last refueling that can be discharged to the Spent Fuel Pool assuming the present licensed capacity and maintaining space for one full core off load.
