Gentlemen:
Subject:. Haddam Neck Team Inspection Report No. 50-213/87-22'
This refers to the special operational' safety inspection conducted by a team
of Region I personnel led by Kenneth Murphy of this office on August 24--
September 4, 1987 at the Haddam Neck Plant, Haddam Neck, Connecticut of activities
authorized by NRC License No. OPR-61 and to the discussions of our findings held -
by Mr. Murphy with members of your staff at the conclusion of the inspection.
Areas examined during this inspection included systems and operator actions
selected from the accident sequences described in the "Probabilistic Safety
Study" (PSS) prepared by NUSCO. The inspection focused on the availability of
critical components as evidenced by plant conditions, operating experience, and
the implementation of surveillance and maintenance programs.
In addition, the
inspection examined the ability of the Haddam Neck staff to use procedures and
equipment to respond to and recover from certain' postulated accident sequences.
These areas are described in the NRC Region I Inspection Report which is enclosed
with this letter.
Within these areas, the inspector examined selected procedures and representative
records, conducted interviews with personnel, inspected plant equipment, and
observed simulated emergency operations by plant personnel.
Overall, the results of the inspection indicate'that the plant staff and emergency
core cooling systems are capable of reliable response to the two domir, ant accident
sequences identified in the current PSS. This conclusion assumes that the main-
tenance initiatives and recent modifications to the charging pumps will reduce
down time and eliminate shaft breakage
The inspection report summarizes other
positive initiatives by your staff including the recent involvement of your PSS
staff in the safety review of design projects at the formative stage.
