Gentlemen:
In accordance with the <Ha'v=im of a reactor coolant inventory tracking system in References (a) and (b), we are currently completing contract documents for engineering, procurement, and inneaBnHm of Combustion Ergineering Heated Junction Thermocouple (HJTC) systems for Calvert Cliffs Units 1 and 2.
At this time we expect engineering arx1 rocurement schedules to support the t
l following insta11a' ion dates. For Unit 1, HJTC system installation willbe completed at the end of the fad,1986 Unit 1 refueling outage, approximately February 1,19G7. For l
Unit 2, irdatation will be completed at the end of the fad,1985 Unit 2 refueling
~
outage, approximately January,1986. Following one fuel cycle of fr** Mad service, we willbe in a pnalHm to evaluate the operationalstatus of these systems.
The pizun.-apecific information requested inItem 2 of Reference (c) fx the reactor coolant inventory tracking system is to be developed following completion of contract documents with Combustion Engineering. We expect to provide this information ft N7 O
