Dear hir. Opeka:

This refers to the safety inspection conducted by hir. P. Swetland of this of0cc on
Septemt'er 8,1992, through October 27,1992, at hiillstone Station in Waterford,
Connecticut. The preliminary findings were discussed with hir. S. Scace, the Unit Directors,
and others of your staff at the conclusion oi the inspection. Areas examined during the
inspection are described in the enclosed report. Within these areas, the inspection focused on
>
issues important to public health and safety, and consisted of performance observations of
ongoing activities, independent veri 0 cation of safety system status and design configuration,
interviews with personnel, and review of quality records.
Within the scope of this inspection, the inspectors noted two problems for which enforcement
discretion was exercised in accordance with Section Vll.B of the Enforcement Policy and no
violations were cited. Inconsistent reporting of fire barrier discrepancies among the hiillstone
units resulted in several missed Unit I licensee event reports. This minor problem was
promptly corrected by your staff. Unit I also reported on a potentially significant
degradation of the service water and emergency service water systems during this inspection,
lixternal corrosion of certain pipe connections rendered the system unable to meet the stress
requirements for a safe shutdown carthquake. Your initiative in finding and promptly
correcting this problem, as well as the absence of prior experience and programmatic
requirements which would have prevented its occurrence, justified the use of er.forcement
discretion for this incident. However, similar occurrences in the future may result in stronger
enforcement action. During this inspection, we also noted that your response to an identified
pin hole leak in the service water supply to the Unit 3 engineered safeguards building was
comprehensive and demonstrated a high regard for maintenance of system integrity.
We note that you have committed to develop and implement by February 1993 a
comprehensive service water and emergency service water maintenance and inspection
strategy. Because of the above noted Unit I_ system degradation, as well as the importance of
proper maintenance of these systems, we have a particular interest in this strategy.
Therefore, you are requested to inform us in writing of any changes in your planned

schedule, as well as to send us a copy or summary of the stiategy within 30 days after it is
approved. The response requested is not subject to the clearance pmcedures of the Office of
Management and liudget as required by the Paperwork Reduction Act of 1980, Public law
No. 96.511.
Finally, some discrepancies were noted in your implementation of corrective actions for
previously cited violations, Management has not assured the proper attention to revised
measures, such as the Plant incident Report process, designed to improve the timeliness of
your response to plant problems We are concerned that this situation could detract from
your performance enhancement program initiatives to improve procedural adherence at the
station.
Your cooperation with us is appreciated.
Sincerely,
.. ,
