Start Preamble

AGENCY:

Nuclear Regulatory Commission.

ACTION:

Draft regulatory issue summary; request for comment.

SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC) is seeking public comment on draft regulatory issue summary (RIS) 2014-XX. This draft RIS is addressed to all holders of an operating license or construction permit for a pressurized water nuclear power reactor under the NRC's regulations, except those who have permanently ceased operations and have certified that fuel has been permanently removed from the reactor vessel. This draft RIS would inform these entities about reactor coolant system Alloy 82/182 branch connection dissimilar metal nozzle weld that may be of a butt weld configuration and therefore require inspection under the NRC's regulations. This RIS also informs these entities of a licensee's recent misclassification and missed inspections to Alloy 82/182 dissimilar metal butt welds in branch connections of primary coolant loop piping.

DATES:

Submit comments by December 8, 2014. Comments received after this date will be considered if it is practical to do so, but the NRC is able to assure consideration only for comments received on or before this date.

ADDRESSES:

You may submit comment by any of the following methods (unless this document describes a different method for submitting comments on a specific subject):

  • Federal Rulemaking Web site: Go to http://www.regulations.gov and search for Docket ID NRC-2014-0232.

II. Background

The NRC issues RISs to communicate with stakeholders on a broad range of regulatory matters. This may include communicating staff technical positions on matters that have not been communicated to or are not broadly understood by the nuclear industry. The NRC staff has developed draft RIS 2014-XX, “Applicability of ASME Code Case N-770-1 As Conditioned In 10 CFR 50.55a, “Codes and Standards,” To Branch Connection Butt Welds,” to inform addresses about reactor coolant system Alloy 82/182 branch connection dissimilar metal nozzle welds that may be of a butt weld configuration and therefore require inspection under 10 CFR 50.55a(g)(6)(ii)(F). The RIS, if issued in final form, would be used by all holders of an operating license or construction permit for a pressurized water nuclear power reactor under 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities,” except those who have permanently ceased operations and have certified that fuel has been permanently removed from the reactor vessel. The draft RIS explains that these entities should review this information for applicability to their Alloy 600 management plan to ensure all applicable butt welds are being inspected.
