NUCLEAR REGULATORY COMMISSION

10 CFR Part 61

[NRC-2011-0012]
RIN-3150-AI92


Workshop on Performance Assessments of Near-Surface Disposal 
Facilities: FEPs Analysis, Scenario and Conceptual Model Development, 
and Code Selection

AGENCY: Nuclear Regulatory Commission.

ACTION: Public meeting.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or the Commission) 
plans to conduct a workshop on performance assessments of near-surface 
low-level radioactive waste (LLW) disposal facilities. The workshop has 
been developed to facilitate communication among Federal and State 
agencies, industry representatives, contractors, and members of the 
public on three aspects of a performance assessment: (1) Features, 
Events, and Processes (FEPs) analysis, (2) the development of scenarios 
and conceptual models, and (3) the selection of computer codes. 
Information gathered from invited subject matter experts, stakeholders, 
and other interested members of the public will be used to improve 
guidance on performance assessments for near-surface disposal of LLW.

DATES: The workshop will be held on August 29 and August 30, 2012.

ADDRESSES: The public meeting will be held (registration begins at 7:30 
a.m.) at the NRC Auditorium, 11545 Rockville Pike, Rockville, Maryland 
20852. The NRC welcomes active participation from those attending. 
Members of the public will be able to participate via telephone and 
webinar. The telephone and webinar information is provided below.

II. Background

    The Commission's licensing requirements for the disposal of LLW in 
near-surface [approximately the uppermost 30 meters (100 feet)] 
facilities reside in Title 10 of the Code of Federal Regulations (10 
CFR) Part 61, ``Licensing Requirements for Land Disposal of Radioactive 
Waste.'' These regulations were published in the Federal Register on 
December 27, 1982 (47 FR 57446). The regulations emphasize an 
integrated systems approach to the disposal of commercial LLW, 
including site selection, disposal facility design and operation, 
minimum waste form requirements, and disposal facility closure. In 
connection with demonstrating compliance with 10 CFR Part 61, a 
performance assessment is used to quantitatively evaluate potential 
releases into the environment and the resultant radiological doses. NRC 
guidance for developing performance assessments can be found in NUREG-
1573. Currently, the NRC is considering a revision to 10 CFR Part 
61.\1\

III. NRC Public Meeting

    The purpose of this public meeting is to facilitate communication 
and gather information from Federal and State agencies, industry 
representatives, contractors, and members of the public concerning 
performance assessments of near-surface disposal facilities. 
Stakeholders and other interested members of the public will have an 
opportunity to pose questions directly to presenters and panelists in 
each of the sessions. Information gathered in the meeting will be used 
to improve guidance on performance assessments for near-surface 
disposal of LLW. The workshop will be organized into four sessions 
comprising a series of presentations followed by panel discussions of 
invited subject matter experts. The workshop sessions are as follows:
     Session 1: Performance Assessment Overview: US and 
International Approaches to Performance Assessment and Experiences with 
Analyses for LLW
     Session 2: Analysis of FEPs for Near-Surface Disposal 
Facilities
     Session 3: Scenario and Conceptual Model Development
     Session 4: Code Selection and Implementation, Model 
Abstraction, and Confidence Building Activities
    The public meeting will be held on August 29 and August 30, 2012, 
from 8:00 a.m. to 5:00 p.m. (registration begins at 7:30 a.m.) in the
