SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION BULLETIN 88-05 PRODUCTS FORMS OTHER THAN FITTINGS AND FLANGES FOR PALO VERDE NUCLEAR GENERATING STATION, UNITS I, 2 AND 3 (TAC NOS. 77041, 77042 AND 77043)
By letter dated May 18, 1990, the NRC requested Arizona Public Service Company (APS) to provide information regarding the disposition of product forms other than fittings and flanges supplied by Piping Supplies Incorporated (PSI), West Jersey Manufacturing (WJM), and Chews Landing Metal Manufactures (CLM).
APS responded to this issue in a submittal dated June 8, 1990.
Based on our review of the submittal, we find that additional information is needed in order to complete our evaluation.
We ask that the information requested by the Enclosure be provided within 30 days from receipt of this letter.
The reporting and/or recordkeeping requirements of this letter affect fewer than ten respondents; therefore, OMB clearance is not required under P.L.96-511.
Sincerely,
Enclosure:

RE VEST FOR ADDITIONAL INFORMATION ENCLOSURE FOR PALO VERDE NUCLEAR GENERATING STATION UNITS I 2 AND 3 REGARDING BULLETIN 88-05 LUG MATERIAL 1.
What is the design code used for the evaluation of the welded lugs'hat is the design code the lugs were originally designed to2 2.
In the bounding calculations for the lugs, what is the assumed maximum stress values for the pipe wall and weld's this str ess assumed to be the maximum pull-out shearing stress where the lug is attached're the bounding calculations for lugs attached to pipe elbows'rovide sample bounding calculations.
3.
What are the assumptions in the bounding analysis regarding the limiting lug dimensions, stress
- areas, the stress concentration factors, and the theory of failure.
Are Welding Research Council (WRC) Bulletins 107, 198, and 297 used in these bounding calculationsf 4.
Provide the results of sample tensile and chemical tests of the lug material from warehouse stock and sample hardness tests of the installed lugs to demonstrate the adequacy of the bounding lug strength assumption.
