SUPPLEMENTARY INFORMATION: The ASME/ANS Joint Committee on Nuclear Risk Management (JCNRM) plans to publish three Probabilistic Risk Assessment (PRA) standards for trial use at the end of this calendar year or the beginning of 2015: (1) Low Power Shutdown PRA Standard, (2) Level 2 PRA Standard and (3) Advanced Light Water Reactor (ALWR) PRA standard. At a public meeting, the NRC seeks to discuss with interested stakeholders options for the NRC to endorse use of these standards.

The NRC has been discussing multi-unit risk for many years with limited discussion on multi-module risk. The NRC staff plans to discuss their expectations for Multi-Module risk in a public meeting and in a white paper entitled "Multi-Module Risk-NRC Expectations" (ADAMS Accession No. ML14150A330). The paper will be issued and available to the public by June 20, 2014.

II. Public Meeting

The public meeting will be held in Rockville, Maryland, at 21 Church Street in Room CSB 06B1 on June 26, 2014, at 8:00 a.m.

There will be two items on the agenda for the meeting. The first agenda item will be to discuss staff options for endorsement of the ASME/ANS standards to be issued for trial use and to solicit stakeholder input. The second agenda item will be discussion of the NRC white paper entitled "Multi--Module Risk-NRC Expectations" (ADAMS ML ML14150A330) which will be available to the public by June 20, 2014.

The purpose of these agenda items is for the NRC staff to answer questions, to provide clarification regarding the white paper, and to solicit early stakeholder comments on both of these subjects. This meeting will be a Category 2 public meeting.
