ENCLOSURE
Staff Assessment of Duke Power Company's
Denial of a Violation Related to
Oconee Nuclear Station
Inspection Report Nos. 50-269/85-25, 50-270/85-25, and 50-287/85-25
Region II has reviewed the licensee's response and concluded that there is
sufficient justification for considering the violation as stated.
Specifically:
1.
NRC Region II agrees with the licensee that specific operability and
surveillance requirements for the Reactor Building (RB) Hydrogen Monitoring
System are not included in the 10 CFR 50.44(b) or NUREG-0737, Item II.F.1.6;
however, the requirement for the system and its purpose is clearly stated.
It is clear that while Duke Power Company is awaiting NRC approval of a
proposed Technical Specification, the licensee is obliged to provide
compensatory measures in the event of system failure to ensure operability
of the RB Hydrogen Monitoring System, thereby providing reasonable assurance
that the system will perform its intended purpose accurately and effectively
under accident conditions.
Although the licensee states that RB Hydrogen
Monitoring System's operability and surveillance requirements are contained
in proposed Technical Specifications and are presently being administered as
binding by the licensee, the staff understands that these specific controls
were not in place at the time the violation occurred.
As stated in the
,
inspection report, the system was not technically operable under the existing
administrative controls in place at tne time of the violation.
For a
safety-related system such as the RB Hydrogen Monitoring System which
provides indication that is used to trigger certain manual emergency responses,
it is reasonable and sound that that indication be available and accurate for
the system to be considered operable and not simply functional.
2.
The staff recognizes Duke Power Company's response as an opinion rather
than a presentation of additional information which would alter the details
of the event as we understand them.
After due consideration, the staff
concludes that your denial of the violation is not substantiated.
The
violation remains as written.
