SUBJECT:

TECHNICAL SPECIFICATIONS FOR STEAM GENERATOR TUBE PLUGGING IN THE TUBE SHEET REGION (TAC No. 65478)

Re: Haddam Neck Plant The Commission has issued the enclosed Amendment No. 96 to Facility Operating License No. DPR-61 for the Haddam Neck Plant. This amendment is in response to your application dated June 1, 1987.

The license amendment revises Technical Specifications Section 4.10.D.1 to provide long-term acceptance criteria for the steam generator tubes with defects in the rolled region (bottom four inches of the tube) and to update the bases for this criteria. These changes will not affect repair criteria for flaw indications located outside of the roll expansion region. This license amendment will also modify the current requirement that "The plugging limit for sleeves will be determined prior to the 1987 refueling outage .for Cycle 15,"

to "The plugging limit for sleeves will be determined prior to the first refueling outage following sleeve installation," since, to date, no sleeves have been installed at the Haddam Neck Plant. This license amendment also revises Technical Specification Section 4.10.D.2 to delete the exclusion of tube row 37, column 73 in Steam Generator #2 from plugging, sipqe this tube has subsequently been plugged during a mid-cycle shutdown in J,Qly,1986.

V A copy of the Safety Evaluation is enclosed. A Notice of Issuance will be included in the Commission's next regular biweekly Federal Register notice.

Sincerely,

/s/
