Code Case N7120 Supplement 6, 2015 Edition Type: Revised.
Title: Additional Materials for Subsection NF, Class 1, 2, 3, and MC
Supports Fabricated by Welding, Section III, Division 1.
The proposed conditions on Code Case N7120 are the same as the conditions on N7119 that were approved by the NRC in Revision 38 of RG 1.84. When the ASME revised N71, the Code Case was not modified in a way that would make it possible for the NRC to remove the conditions.
Therefore, the conditions would be retained in Revision 39 of RG 1.84.
Code Case N1553 Supplement 5, 2015 Edition Type: Revised.
Title: Fiberglass Reinforced Thermosetting Resin Pipe, Section III, Division 1.
The proposed conditions on Code Case N1553 are the same as the

Alternative Rules for Preservice and Inservice Testing of Active Electric Motor-Operated Valve Assemblies in Light-Water Reactor Power Plants.
Requirements for Safety Significance Categorization of Components Using Risk Insights for Inservice Testing of LWR Power Plants.
Requirements for Risk Insights for Inservice Testing of Check Valves at LWR Power Plants.
Use of a Pump Curve for Testing.
Alternative Requirements for Inservice Testing Using Risk Insights for Pneumatically and Hydraulically Operated Valve Assemblies in Light-Water Reactor Power Plants OMCode 1998, Subsection ISTC.
Alternate Testing Requirements for Pumps Tested Quarterly Within 20% of Design Flow.
Alternative Upper Limit for the Comprehensive Pump Test.
Inservice Test Frequency.

conditions on N1552 that were approved by the NRC in Revision 38 of RG 1.84. When the ASME revised N
1552, the Code Case was not modified in a way that would make it possible for the NRC to remove the conditions.
Therefore, the conditions would be retained in Revision 39 of RG 1.84.
Code Case N7554 Supplement 1, 2017 Edition Type: Revised.
Title: Use of Polyethylene PE Class 3 Plastic Pipe, Section III, Division 1.
This Code Case is applicable only to butt fusion joints and the content was incorporated into Mandatory Appendix XXVI in 2015 Edition of Section III of the ASME Code. The relevant provisions of Code Case N7554 are the same as those in Mandatory Appendix XXVI. Therefore, the NRC is applying the same conditions to Code Case N7554. The NRC has determined that these conditions are necessary to ensure structural integrity of the polyethylene piping and fusion joints

when the polyethylene piping is used in Class 3 safety-related applications.
Code Case N779 Supplement 9, 2007
Edition Type: New.
Title: Alternative Rules for Simplified Elastic-Plastic Analysis Class 1, Section III, Division 1.
The NRC finds the Code Case satisfactory and technically acceptable for use only with code editions Summer 1979 and later. This Code Case, as written, is not acceptable for use with editions of Section III earlier than the Summer 1979 edition, which included the term Delta T1 in NB3600 Equation 10, because the Code Case is based on equations used in the Summer 1979
edition and later editions of the Code.
Code Case N852 Supplement 0, 2015
Edition Type: New.
Title: Application of the ASME NPT
Stamp, Section III, Divisions 1, 2, 3, and 5.
