. Deleted reactor vessel welds AD, BB, BC, BH, BJ, BK, BM, BN, BP, and BR from the l
scope of the relief request. The deleted welds are specified as Category B-A, item B1.10. In accordance with 10CFR50.55a(g)(6)(ii)(A)(1), all previously granted relief for volumetric examination of reactor vessel shell welds specified in item B1.10 of Category B-A are revoked. Additionally,10CFR50.55a(g)(6)(ii)(A)(2) requiles these subject welds to be examined meeting the requiremerds of the 1989 Edition of ASME Section XI except that examination of 90% of the Code specified volume is determined acceptable. This relief request identified limitations on tN listed welds that equated less than 10% of the required Code volume. The listed welds meet the requirements of 10CFR50 (90% of the examination volume) without imposing augmented examination requirements. The remaining welds in the relief request are not Category B-A, item B1.10 and relief is still applicable.
. Deleted Figures 2,8,9,10,11,12,13, and 20 because they corresponded with the deleted welds.

. By revision, this relief request is deleted. This relief request adopted the 1983 Edition, Summer 1983 Addenda of ASME Section XI to clarify the test boundaries of Class 2 pressure tests. With the use of Code Case N-498-1, as approved by the NRC, use of these later Code boundaries no longer required.
Relief Reauest I.00018. Revision 2 (Earlier revision approved by the NRC in letter dated August 15,1986)
. Revised Sections Ill, V, and VI to address the use of Code Case N-498-1 as approved by the NRC. The relief request is revised to recognize the application of a system leakage test performed at each refuel outage (Category B-P, items B15.50, B15.60, and 815.70) and a leakage test performed as an alternative to hydrostatic test (Code Case N-498-1). Because the test boundary for the two leakage tests are different,'
relief is still required for those leakage tests performed at refuel outages.
Relief Reauest 1-00019. Revision 2 (Earlier revision approved by the NRC in letter dated August 5,1986)
Revised Section VI, items 1 and 2 to incorporate changes to the GGNS pressure testing program resulting from NRC approval of Code Case N-498-1.
Relief Reauest 1-00024. Revision 0 (Initial submittal)
. This is a new relief request seeking permission to use the 1989 Edition of ASME Section XI, Examination Category B-L-2 and B-M-2, Note 2 to preclude disassembly of Class 1 pumps and valves solely for the purpose of performing visual inspection of the intemal surfaces. With approval of this relief request, the visualinspection will be performed when the pump or valve is disassembled for other reasons, e.g.,
maintenance, repair, or volumetric examination.
