SUBJECT:
Beaver Valley Power Station - Unit No. 2 Docket No. 50-412 Safety-Related Instrument Sensing Lines Gentlemen:
9 Duquesne Light Company (DLC) has completed an intensive review and evaluation of safety-related instrument sensing lines utilized at BVPS-2, including consideration of the guidance of Regulatory Guide 1.151, Revision 0.
The results of this evaluation are reflected in the attached BVPS-2 position on this regulatory guide.
This position will be incorporated into FSAR Table 1.8-1 in a future FSAR amendment.
The program for installation of safety-related ins trume nt sensing lines, described in the attached pos it ion, will be beneficial from both a cost and schedule standpoint, while having no adverse ef fects on the quality of instrument sensing line installation or on plant safety.
It is DLC's understanding that the NRC has reviewed and concurred with similar programs for instrument sensing lines that have been established at other plants.
In orde r to provide for optimization of these cost and schedule benefits through expeditious impleme nt at ion of this program, DLC requests that the NRC review the attached information and provide concurrence and any comments by May 3, 1985.
Any questions or comments on this submittal may be directed to Mr.
J. D. O'Neil of our Licensing staff at (412) 923-1960.

e-BEAVER VALLEY POWER STATION - UNIT NO. 2 Position on Regulatory Guide 1.151, Revision 0, dated July 1983 (" Instrument Sensing Lines")
The design and installation criteria for safety-related instr v nt sensing lines at BVPS-2 meet the intent of this Regulatory Guide with tne following alternatives and clarifications provided for Regulatory Positions C.2 and C.3:
Class breaks are established in accordance with ISA-S67.02 as modified by this Regulatory Guide with the following alt erna-tives and clarifications:
1.
All components (i.e., tubing, fittings, valves, and gages) i of the instrument sensing lines are designed to Seismic Category I requirements and are designated QA Category I.
These casponents are not under ASME Section III jurisdic-tion, but they are designed,. fabricated, and installed utilizing ASME Section III as guidance.
The ins trume nt sensing lines are identified as Nuclear Safety-Related in lieu of Safety Class 2 or Safety Class 3.
2.
All documentation and material traceability for the instru-ment sensing. line components is maintained for the procure-ment phase of these components. Full quality control on weld rsd traceability is maintained through weld data sheets.
3.
Since the instrument sensing line compo nent s,- including N-s tanped valves, are identified as Nuclear Safety-Related in lieu of being under ASME Section III jurisdiction, these components are not under ANI jurisdiction nor under the eventual jurisdiction of ASME Section XI.
