ATTACHMENT 1 Safety Evaluation for Proposed Changes to the FNP-2 Technical Specifications I. Background On October 22, 1982, Joseph M. Farley Nuclear Plant - Unit 2 shut down for the first refueling outage. In accordance with the operating license, NPF-8, some design changes and submittal of additional information prior to startup following the first refueling outage are required. Specifically, the requirements that affect the technical specifications are: the addition of containment penetration overcurrent protection devices, license condition 2.C.(19)(b);
replacement of the containment vent valves, license condition 2.C.(17);
and tabulation of a list of safety-related mechanical snubbers, Technical Specification Table 3.7-4b. Therefore, proposed technical specification changes, as contained in Attachment 2, are necessary to provide conformance with the aforementioned license conditions.
II. References Operating License NPF-8 as amended FNP-2 Technical Specifiations III. Bases License Condition 2.C.(19)(b)
License condition 2.C.(19)(b), as amended, requires the modification of circuit protection devices in the containment penetration circuits.
The modifications are described in the Alabama Power Company letter of November 17, 1980, and were approved in the NRC Safety Evaluation Report, Supplement No. 5, dated March 1981.
l Many of the required circuit modifications will be completed during the first refueling outage while the remainder of the modifications will be completed no later than the second refueling outage. Since it will not be known exactly how many of the modifications will be completed until just prior to startup from the first refueling outage, all of the circuit nodifications are included in the proposed technical
, specification table change (Table 3.8-1) with a footnote stating that only the installed protection devices will be covered by the l
requirements of section 3/4.8.3.1 until the second refueling, at which time all protection devices listed will be covered. This approach allows early submittal of the proposed technical specification table change and eliminates the need for a subsequent technical specification change during the second refueling outage.
- Some changes to the November 17, 1980 proposed design have been made l and are reflected in the proposed technical specification change. All l of the changes are in accordance with licensing requirements. The specific changes to the modifications detailed in the November 17, 1980 letter are

- 3. These circuits were proposed to be protected by MSCP fuses.
However, due to design changes in the circuits, other backup protection has been provided by circuit breakers.
A. Table - 3 600V AC Motor Control Centers The following backup protection is provided instead of MSCP Type "U" fuses:
Backup Service Feeder Compartment Protection Accumulator 2A FU-Z2 Q2R18B032-A Discharge Valve (HE63-8050)
Accumulator 2C FU-Z3 Q2R18B031-A Discharge Valve (HE63-8050)
Accumulator 2B FV-S2 Q2R18B035-B Discharge Valve B. Table - 10 Lighting Panels The MSCP Type "Y" fuses proposed for lighting panels have been deleted as a result of modifications that introduce a local control panel outside containment for each lighting panel.
These local control panels have a breaker to provide backup protection.
