!!!IN 9140 Document C antrol Desk U.S. Nuclear Regulatory Commission Washington, D.C. 20545 Attention:
Charles L. Miller, Director Standardization and Non Power Reactor Project Directs rate
Subject:
Reactor Coolant Pressure lloundary Components Applicable Inservice inspection Code Cases for Gli AllWR linclosed are thirty four (34) copies of a modification to the Table 5.2-1 of the AllWR SSAR, eliminating ASMiiinservice inspection Code Cases N 322 and N.390 which have not been incorporated into Regulatory Guide 1.147, llowever, GE is requesting permission to use Code Case N 479 (the last Code Case of Table 5.21) for the AllWR Standard Plant, although this Code Case has not yet been incorporated into Regulatory Guide 1.147, Permission to use this Code Case is being sought under the provision of 10CFR50 Section 50.55a(a)(2)(ii), as provided for in 50.55a Footnote 6. Code Case N 479 allows non isolatable Class 2 portions of the rnain 3. team system to be hydrostatically tested in conjunction with the class I system. Using this procedure eliminates the need to block the containment isolation valve which is otherwise necessary to avoid pressure leakage into the Class I side of the system and possible damage to the valve. The hydrostatic tcst performed on the subject portion of the Class 2 main steam line,vould meet the requirements of IWA 5000 and lW13 5222 thereby assuring safe plant operatioS,

Since GE is ar.ticliating that the NRC will grant permission to use Code Case N.479 on the AllWR Standard P, ant, the attached markup has retained Code Case N-479. Gli intends to delete Code Cases N.322 and N.390 in a future amendment.
