The use of these Code Cases is not presently referenced in NRC Regulatory Guide 1.147, Inservice Inspection Code Case Acceptability, Revision 10, dated July, 1993. Code Case N-498-1 provides alternative rules for Class 1, 2, and 3 (Table IWB, C, and D-2500-1, Categories B-P, C-H, D-A, D-B, and D-C) ten-year system hydrostatic tests. This Code Case allows a system leakage/system pressure test to be conducted in lieu of a hydrostatic test, subject to the test criteria in the Code Case. Code Case N-524 provides alternative examination requirements for longitudinal welds in Class 1 and 2 piping, Section XI, Division I.

Code Case N-498-1, entitled Alternative Rules for 10-Year System .
Hydrostatic Testing for Class l, 2, and 3 Systems was approved by the ASME and published on May 11, 1994. Code Case N-524, entitled Alternative Examination Requirements for Longitudinal Welds in Class 1 and 2 Piping was approved by the ASME and published on August 8, 1993. The use of these Code Cases is not presently referenced in NRC Regulatory Guide 1.147, Inservice Inspection Code Case Acceptability, Revision 10, dated July, 1993.
Code Case N-498-1 provides alternative rules for Class 1, 2, and 3 (Table IWB, C, and D-2500-1, Categories B-P, C-H, D-A, D-B, and D-C) ten-year system hydrostatic tests. This Code Case allows a system leakage/system pressure test to be conducted in lieu of a hydrostatic test, subject to the test criteria in the Code Case.

Case N-524 Alternative Examination Requirements for Longitudinal Welds in Class 1 and 2 Piping Section XI, Division 1 Inquiry: What alternative requirements may be ap-plied to the surface and volumetric examination of longitudinal piping welds specified in Table IWB-2500-1, Examination Category B-J, Table IWC-2500-1, Examination Categories C-F-1 and C-F-2 (Exam-ination Category C-F prior to Winter 1983 Adden-da), and Table IWC-2520, Examination Category C-G (1974 Edition, Summer 1975 Addenda)?
Reply: It is the opinion of the Committee that the following shall apply:
(a) When only a surface examination is required, examination of longitudinal piping welds is not re-quired beyond those portions of the welds within the examination boundaries of intersecting circumfer-ential welds.
(b) When both surface and volumetric examina-tions are required, examination of longitudinal piping welds is not required beyond those portions of the welds within the examination boundaries of inter-secting circumferential welds provided the following requirements are met.
(1) Where longitudinal welds are specified and locations are known, examination requirements shall be met for both transverse and parallel flaws at the intersection of the welds and for that length of lon-gitudinal weld within the circumferential weld ex-amination volume; (2) Where longitudinal welds are specified but locations are unknown, or the existence of longitu-dinal welds is uncertain, the examination require-ments shall be met for both transverse and parallel flaws within the entire examination volume of inter-secting circumferential welds.
