SUBJECT:

Technical Specifications Concerning Low Temperature Overpressurization Protection System Modifications

. Haddam Neck Plant The Commission has issued the enclosed Amendment No. 94 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 the heat-up rate curve (Figure 3.4-8) and also provides a larger interval for which the low-temperature pressurization protection system (LTOPS) must be placed into operation. More specifically, the proposed heat-up rate change results in a pressure / temperature limit curve shift. This shift increases the temperature range over which the LTOPS can effectively be placed into operation and decreases the probability of operator error during plant heat-up and cooldown operations.

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/

Francis M. Akstulewicz, Jr, Project Manager Integrated Safety Assessment Project Directorate Division of Reactor Projects III/IV/V and Special Projects
