l ATTACHMENT I REPLY TO A NOTICE OF VIOLATION INSPECTION REPORT 50-456/457/95013 VIOLATIONS (50-456/457/95013-01k Technical Specification 3.3.1 requires that with a main control room air intake radiation mcaitor inoperable, within one hour switch to the redundant train of control room ventilation, or isolate the control room ventilation system and initiate operatien of the control room make-up system.
Contrary to the above, on September 8,1995, the OA main control room air intake radiation monitar was declared inoperabic and the licensec failed to switch to the redundant train of control roon ventilation, or isolate the control room ventilation system and initiate operation of the control roon make-up system within one hour as required.
This is a Severity Level IV violation (Supplement I).
REASON FOR THE VIOLATION:
A failed'o-ring on radiation momtor OPR32J skid's gas channel detector plug allowed leakage to the atmosphere and produced a low flow condition within the skid which rendered the monitor inoperable.
J Because of personnel error, corrective actions were not performed in a timely manner. Additionally, there was a lack of teamwork and a lack questioning attitude between the Unit Supenisor, Unit 1 Nuclear Statica Operator (NSO), Unit 2 NSO and the extra NSO. Actions taken were not adequate to
- ensure the Technical Specification requirements were met within the one hour time frame.
CORRECTIVE STEPS TAKEN AND RESULTS ACHIEVED:
Personnel involved in the event were counseled concerning their performance relating to the event and management's expectations regarding teamwork, standards, and a questioning attitude.
Each operating crew was briefed on the circumstances of the event and how management's expectations were not met.
i The failed o-ring was replaced.
CORRECTIVE STEPS TA"EN TO AVOID FURTHER VIOLATION:
Operating Department Memo andum #7-95, ' Individual Responsibilities for Technical Specification Adherence,"was issued and cemmunicated to Operating personnel. The purpose of this policy is to clearly define the obligation of the shift license holders to ensure that proper Technical Specifications are entered and adhered to when the required plant equipment does not meet conditions of operability.
Teamwork is being stressed during simulator training for Operating Department personnel. This is accomplished during briefs held prior to the simulator training and during the actual simulator training.

Training will include management's expectations that reactor operators and senior reactor operators are equally responsible in ensuring that the units are in compliance with the Technical Specifications. The ciTectiveness of -
this training will be assessed by July 31,1996, which is the midpoint of the 1996 training cycle.
DATE WHEN FULL COMPLI ANCE WILL BE ACHIEVED; Full compliance was achit,ved on September 8,1995, when the action requirements were met. Repairs to the radiation monitor skid were completed on September 13,1995, and the action requirement was exited.
