l manufacturers to weld repair austenitic forgings without resolution heat treatment should justify to the NRC staff (through the safety analysis report) why this is acceptable for their applications, including their evaluation of the susceptibility for stress-corrosion cracking. 7/18/85 N-391 Procedure for Evaluation of the Design of Hollow Circular Cross Section Welded Attachments on Class 1 Piping, Section III, Division 1 7/24/89 N-391-1 Procedure for Evaluation of the Design of Hollow Circular Cross Section Welded Attachments on Class 1 Piping, Section III, Division 1 The following typographical errors need to be corrected: (1) In Equation 3, the + sign should be changed to an = sign. (2) In Equation 4, the first + sign should be changed to an = sign. 8/24/95 N-392 Procedure for Evaluation of the Design of Hollow Circular Cross Section Welded Attachments on Classes 2 and 3 Piping, Section III, Division 1 12/11/89 N-392-1 Procedure for Evaluation of the Design of Hollow Circular Cross Section Welded Attachments on Classes 2 and 3 Piping, Section III, Division 1 Applicants should identify the following in their safety analysis report: (1) the method of lug attachment (2) the piping system involved (3) the location in the system where the Code Case will be applied 12/11/92 N-392-2 Procedure for Evaluation of the Design of Hollow Circular Cross Section Welded Attachments on Classes 2 and 3 Piping, Section III, Division 1 Applicants should identify in their safety analysis report: (1) the method of lug attachment (2) the piping system involved (3) the location in the system where the Code Case will be applied 12/12/94 N-411 Alternative Damping Values for Seismic Analysis of Classes 1, 2, and 3 Piping Sections, Section III, Division 1 (1) The damping values specified may be used to analyze piping response for seismic and other dynamic loads that are being filtered through building structures provided that the response mode frequencies are limited to 33 hertz and
