Dear Mr. Sylvia:
SUBJECT:
SERVICE WATER SYSTEM OPERATIONAL PERFORMANCE
INSPECTION AT NINE MILEPOINT, UNITS 1 & 2 (NRC COMBINED
INSPECTION REPORT NOS. 50-220/93-80 AND 50-410/93-80)
This letter refers to the NRC team inspection conducted from June 16 to July 16, 1993, at
the Nine Mile Point Station, Units 1 & 2 at Scriba, New York to evaluate the adequacy of
your actions in response to NRC Generic Letter 89-13, "Service Water System Problems
Affecting Safety-Related Equipment."
This generic letter provided recommendations
to
licensees for the development of programs to ensure operability of service water (SW)
systems that perform vital functions in protecting public health and safety during postulated
design-basis
accidents.
The purpose of this inspection was to verify that the Units 1 & 2 SW
systems were designed,
operated,
tested, and maintained in a manner such that they were
capable of performing their intended safety function.
The NRC team reviewed your recently completed audits of the Units 1 & 2 SW systems.
The team concluded that your Unit 1 SW audit was well planned, implemented, and
documented.
The team independently verified your SW audit conclusion that the Unit 1 SW
systems were sufficiently designed,
operated,
tested, and maintained to assure performance of
design safety functions under postulated accident conditions.
Therefore, we have concluded
that your Unit 1 SW audit was an acceptable alternative to a fuH scope NRC inspection
conducted, using NRC Temporary Instruction 2515/118, "Service Water System Operational
Performance Inspection."
The team observed a weakness in your Unit 1 zebra mussel
control program, which you agreed to review for corrective action.

Mr. B. Ralph Sylvia
Although Unit 2 was not programmed for inspection under the Temporary Instruction,
selected aspects of the service water system were examined because of prior operational
problems.
The team's review of Unit 2 focused on two unresolved items associated
with SW flow
degradation problems.
While both of these items have been resolved adequately for the short
term, your staff indicated that you intend to implement long term corrective actions for
improving SW system performance at Unit 2.
The results of this inspection,
as detailed in the enclosed report, were discussed with your
staff during the exit meeting on July 16, 1993. At the exit meeting, your staff acknowledged
the inspection findings and agreed to meet with us in Region I later this year regarding the
Unit 1 zebra mussel control program and the long term corrective actions for improving SW
system performance at Unit 2.
Please provide us the earliest possible date for a meeting in
Region I that you can support to discuss your final plans regarding resolution and closure of
the degraded flows in Unit 2 and the zebra mussel infestation affecting Unit 1.
Your cooperation with us in this matter is appreciated.
Sincerely,
