A?u i d 19PA Docket No. 50-397 MEMORANDUM FOR: Thomas M. Novak, Assistant Director for Licensing Division of Licensing FROM: William V. Johnston, Assistant Director Materials, Chemical & Environmental Technology Division of Engineering

SUBJECT:

WPPSS, WASHINGTON NUCLEAR PROJECT NO. 2, INSERVICE INSPECTION PROGRAM Plant Name: Washington Nuclear Project No. 2 (WNP-2)

Suppliers: General Electric; Burns & Roe Licensing Stage: Operating Reactor Docket Number: 50-397 Responsible Branch and Project Manager: LB #2, R. Auluck Reviewer: M. R. Hum Requested Completion Date: April 6, 1984 Decription of Task: Review of the Inservice Inspection Program Review Status: Licensee's Response Required In accordance with a request from the Project Manager, the Inservice Inspection Section, Materials Engineering Branch, Division of Engineering, has reviewed the licensee's letter dated March 20, 1984 ( Serial Number G0 2-84-156) concerning the inservice inspection of ASME Code Class 2 systems. The licensee is preparing the initial Inservice Inspection (ISI)

Program for WNP-2. The licensee has requested that the Commission evaluate and approve a plant-specific alternative inspection program for the selection and examination of Class 2 piping which consists of using paragraphs IWC-1220, IWC-1221, IWC-1222 and Table IWC-2500, Examination Category C-F, from the 1983 Edition of Section XI of the ASME Code including Addenda through Winter 1983.

These requirements would be used by the licensee in lieu of the mandatory requirements for Class 2 piping systems defined in 10 CFR 50.55a(g)(4).

The reason that the licensee has made this request is the 1983 Edition of Section XI has not yet been referenced in the regulations.
