rostatic Testing of Internal Piping, Section III, Division 1, Classes 2 and 3 5/25/83 N-242 Materials Certification, Section III, Division 1, Classes 1, 2, 3, MC, and CS Construction Applicants should identify the components and supports that require the use of Paragraphs 1.0 through 4.0 of the Code Case in their safety analysis reports. 4/10/80 N-246 Use of SB-169 Alloy CA614, Section III, Division 1, Class 3 9/7/82 N-246-1 SB-169, Alloy C 61400, Section III, Division 1, Class 3 5/25/83 N-249 Additional Materials for Component Supports Fabricated without Welding, Section III, Division 1, Subsection NF, Class 1, 2, 3, and MC Component Supports Footnote 2 of the Code Case should apply to all materials listed in Tables 1, 2, 3, 4, and 5 of the Code Case and should be so indicated on line 5 of the “Reply.” 5/11/81 N-249-1 Additional Materials for Component Supports Fabricated without Welding, Section III, Division 1, Subsection NF, Class 1, 2, 3, and MC Component Supports Paragraph 7 of the “Reply” should reference the requirements in Paragraph NF-2600 instead of those in Paragraph NF-2800. This is a typographical error because Paragraph NF-2800 does not exist. 6/17/82 N-249-2 N-249-3 Additional Materials for Subsection NF Class 1, 2, 3, and MC Component Supports Fabricated without Welding, Section III, Division 1 2/14/83 2/20/84 N-249-4 N-249-5 Additional Material for Subsection NF, Classes 1, 2, 3, and MC Component Supports Fabricated without Welding, Section III, Division 1 The fracture toughness requirements, as listed in Code Case N-249-4, apply only to piping supports and not to Classes 1, 2, and 3 component supports. The fracture toughness of Classes 1, 2, and 3 component supports should be characterized in accordance with Section 5.3.4 of NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition” (SRP) (Ref. 17), or on a case-by-case basis. 9/17/84 4/8/85 N-249-6 N-249-7 N-249-8 N-249-9
