I. Background

    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.

    Dated at Rockville, Maryland, this 11th day of June 2014.

    For the Nuclear Regulatory Commission.
