The U.S. Nuclear Regulatory Commission (NRC) is seeking public comment on a draft regulatory issue summary (RIS). The draft RIS informs all addressees of a clarification of the requirements for the bare metal visual examination.

The draft RIS is relevant to all holders and applicants for a pressurized-water power reactor (PWR) operating license or construction permit, except those that have certified that they have permanently ceased operations and have permanently removed all fuel from the reactor vessel.

DATES: Submit comments by [INSERT DATE 60 DAYS FROM DATE OF PUBLICATION IN THE FEDERAL REGISTER]. Comments received after this date will be considered if it is practical to do so, but the Commission is able to ensure consideration only for comments received before this date.

This may include communicating and clarifying NRC technical or policy positions on regulatory matters that have not been communicated to or are not broadly understood by the nuclear industry. This draft RIS informs addressees of a clarification of the requirements for the bare metal visual examination, which can be either the visual examination (VE) of the bare metal of the upper head or a visual testing (VT)-2 examination under the insulation to meet the requirements of notes 1 and 4 in Table 1 in the American Society of Mechanical Engineers (ASME) Code Case N-729-4, Alternative Examination Requirements for PWR Reactor Vessel Upper Heads With Nozzles Having Pressure-Retaining Partial-Penetration WeldsSection XI, Division 1.

Proposed Action The NRC is requesting public comments on the draft RIS. The NRC staff will make a final determination regarding issuance of the RIS after it considers any public comments received in response to this request.

Dated at Rockville, Maryland, this 26th day of February, 2018.

For the Nuclear Regulatory Commission.
