SUBJECT:

SAFETY CLASSIFICATION OF INSTRUMENT AIR TUBING AND l COMPONENTS FOR SAFETY RELATED VALVE TOP WORKS AT l WATERFORD STEAM ELECTRIC STATION, UNIT 3 (TAC NO. M99161)

Dear Mr. Dugger:

The staff 2.as reviewed the Entergy Operations, Inc. (EOl), letter dated July 3,1997, as supplemented by letter dated November 13,1998, for an exception to Nuclear Regulatory Commission Regulatory Guide (RG) 1.26, " Quality Group Classifications and Standards for Water, Steam and Radioactive Waste-Containing Components of Nuclear Power Plants,"

regarding the safety classification of instrument Air (IA) tubing and components of safety- i related valve top assemblies at Watarford Steam Electric Station, Unit 3 (Waterford 3). Based i on the enclosed Safety Evaluation, the staff has concluded that your request is acceptable for the lA tubing and components of safety-related valve top assemblies currently installed at l l

Waterford 3. However, the staff has also determined that your request is not justifiable for future installation of simitar components at Waterford 3. Therefore, for future installation or l replacement of IA tubing and components of safety-related valve top assemblies at Waterford 3, the request for exception from the RG 1.26 classification is acceptable, provided .

l the new lA tubing and components of safety-related valve top assemblies at Waterford 3 satisfy l l all Division 1 construction requirements, defined in American Society of Mechanical Engineers /

(ASME) Code Section lil, Subarticle NCA-1110, Article NCA-9000, and Subsection ND, with the following exceptions: 1 0

1. The design may be based on the rules of ANSI B31.1, except that the tubing

(-o/

supports should be designed as Seismic Category 1.

2. The tubing and components may be exempted from the Authorized Nuclear inspection requirement.

The exception from RG 1.26 for installed components represents a non-conformance with the ASME Code and therefore, constitutes a deviation from the plant licensing commitments. The staff therefore, recommends that EOl revise its licensing basis for Waterford 3, to permit incorporation of the change summarized above.
