Dear Sir:

In our letter to you dated April 15,1983 (BECo Letter No. 83-97), we committed

to provide you with our schedule for upgrading the TSC/0SC facilities at the Pilgrim site. Our schedule consists of work in two phases

Phase 1 includes relocation of existing data collaction, displays, com-munications, and console backup power functions, which are now located in the lower level of the main guardhouse, to the new TSC/0SC facility located in the new administration building. We will complete this work by August 31, 1984.

Phase 2 includes the installation of a filtered HVAC system within the TSC/

OSC, a backup power system for TSC/0SC utilities, and an uninterruptible power supply for TSC data links, displays and the future plant process computer. Upon completion of phase 2 work on July 31, 1985, the TSC/0SC

will be equipped to ensure that occupants will not receive doses in excess of General Design Criteria 19 for the duration of an accident which results in radiation sources defined in NUREG-0737.

Should you have any questions or concerns on this submittal, please contact us.

Very truly yours, PMK/ mat
