Gentlemen:

Haddam Neck Plant Millstone Nuclear Power Station, Unit Nos.1 and 2 IMI Item 2.1.3a Direct Indication of PORV and Safety Valve Positions In Reference (1), Connecticut Yankee Atomic Power Company (CYAPCO) and Northeast Nuclear Energy Company (NNECO) documented the fact that direct indication for PORV's and safety valves had been installed for all three operating units. A summary of the qualification program for the installed acoustic monitoring channels was included. The schedule for completing the qualification program was also provided, and it was originally intended that the program would be completed by mid-1980.

In Reference (2), the Staff documented its evaluation of the implementation of the Category A lessons learned requirements at Millstone Unit No. 2.

Regarding Item 2.1.3a, the Staff indicated that NNECO had agreed to have the qualification completed by April 1, 1980.

Recent discussions with the vendor, Babcock and Wilcox, have indicated that completion of the qualification program by April 1 is not feasible. The delay is primarily attributable to the additional time required to finalize the testing program and secure a laboratory facility to perform the tests. The revised date for completion of this effort is April 1,1981.
