NUCLEAR PROJECT NO. 2 SUPPLY SYSTEM RESPONSE TO FSAR QUESTION 110.44

Reference:

(a) Letter, A. Schwencer (NRC) to DW Mazur (SS),

dated August 3, 1983, subject, "FSAR questions 110.41, 110.42, 110.43 and 110.44" The Washington Public Power Supply System hereby provides a reply to FSAR question 110.44 which was submitted as an attachment to reference (a) above. Our reply consists of this letter and 2 attachments.

If you have any questions or desire further information, please contact Pat Powell, Manager, WNP-2 Licensing.

Attachment 1 FSAR uestion 110.44 Section 3.9.3.4 of your FSAR states that all piping and component supports are designed in accordance with Subsection NF of the ASME Code. Provide the criteria used for the other elements of construction, in addition to design. As stated in Footnote 2 to SRP 5.2.1.1 construction includes materials, fabrication, examination, testing, inspection and installation as well as design. Provide sufficient graphic detail so that the bound-aries to which the above construction criteria elements including design are clearly specified. The graphic sketches should provide information for all items in the support load path from the component being supported to the building structure, including any supplementary steel. The purpose of this request is to assure continuity of construction criteria across any jurisdictional boundaries in the support load path.

Su 1 S stem Res onse On August 5, 1983, the Supply System responded 'to an NRC Region V Notice of Deviation on the matter of NF boundaries. That communication is pro-vided as part of this response for purposes of clarity:

In summary, the above response stated that the jurisdictional boundary between ASME Section III, Subsection NF and AISC members has been designated consistent with code requirements and also discusses the equivalency of design for component support members regardless of jurisdictional boundary.

guestion 110.44 requests additional information regarding construction practices for NF and AISC members. The attached table provides summary information regarding the construction requirements in the areas of inspection, fabrication, mater ials, examination, and testing.

Each support is categorized as either guality Class I or guality Class II dependent upon the safety significance of the system being supported.

This quality classification and the applicable code dictate generic construction requirements. The construction requirements for any particu-lar support can be easily established by using design drawing H-501 in conjunction with the support detail. When a jurisdictional boundary exists within a particular support, the applicable code requirements and construction practices are selectively applied to the individual members.

As stated previously, the design of all supports for ASME piping is equivalent to ASME-NF regardless of jurisdictional boundary or quality class.

All ASME and AISC support members meet applicable code and quality requirements, for example, NF support members meet ASME material require-ments and are fabricated using ASME IX welding requirements whereas AISC members meet ASTM material requirements and are fabricated using AWS welding requirements. The above response identified principal differ-ences in the construction of NF and AISC support members. Those material traceability differences do exist on certain AISC members; however,

recent reviews indicate that no differences exist in the nondestructive examination of ASME Class I NF support members as previously stated due 'o the absence of such welds in the AISC scope. In terms of construction continuity the basic differences are: 1) AISC guality Class I members may not have the material identification markings required of NF 1 or NF 2 component support members (NF 2151, 4122), 2) AISC ASCII materials may not have been procured under a 10CFR Part 21 material program, and 3)

AISC ASCII materials may not have been subject to ASME material control and verification requirements during receipt or installation.

It should be noted that AISC guality Class II support members are fab-ricated using essentially the same procedures as AISC gCI although trained field engineers rather than gC inspector s are used for verifi-cation activities.

No substantial differences exist in the construction practices other than those cited above; minor differences do exist between the applic-able codes referenced on the following table such as weld qualification parameters.
