The inspected fire protection equipment is Underwriters Laboratories approved and/or Factory Mutual listed,
b.
ualit Assurance The inspector reviewed "Fire Protection guality Assurance Program, Nine Mile Point 1" dated June 25, 1979.
The inspector verified that the licensee has esta6lished quality assurance requirements for fire protection related systems, structures and components, in accordance with the Branch Technical Position 9.5-1.
c.
Status of Fire Protection Modifications By review and examination of records including specifications and drawings and by examination of installed fire protection equipment, the inspector verified the licensee's implementation of scheduled modifications identified in the Safety Evaluation Report.
The licensee was granted schedular relief on several modifications identified in Table 3 '
of the SER.
Those modifications are identified below.
All other modifications have a completion commitment date of June 1981.

The National Fire Protection Association (NFPA)
Code 72F, Section 4.4 states that the detectors shall not be located where air from supply diffusers could di lute products of combustion before they reach the detector s.
A similar situation may develop once detectors are installed in the walk-in type control room cabinets where fans have been provided to make up for ventilation previously obtained from the auxilary control room.
The licensee stated that the problem will be evaluated prior to placing the fire protection system into service in the effected areas.
This item remains unresolved pending NRC review of the licensee's corrective action.
