NUCLEAR REGULATORY COMMISSION

10 CFR Part 50


Domestic Licensing of Production Utilization Facilities; Risk-
Informed Revisions, Option 3 (SECY-98-300)

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of public workshop.

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

SUMMARY: The Nuclear Regulatory Commission has instructed the staff to 
pursue a study to explore changes to the body of the part 50 
regulations, to incorporate risk-informed attributes which is Option 3 
in Secy-98-300. This study will result in recommendations to the 
Commission on any specific regulatory changes that should be pursued, 
and the corresponding schedules and resource needs. The staff intends 
to conduct a workshop to solicit information related to these changes.

DATES: The workshop will be held on September 15, 1999.

ADDRESSES: The workshop will be held at the Doubletree Hotel, 1750 
Rockville, Pike, Rockville, Maryland 20852. Telephone No. 301-468-1100.

Regulatory Research, MS: T10-E50, U.S. Nuclear Regulatory Commission, 
Washington DC 20555-0001, (301) 415-6675 email: [email protected].

SUPPLEMENTARY INFORMATION: Listed below are example topics on which 
discussion and feedback are sought from the public at the workshop:
    1. Which regulations of 10 CFR Part 50 are candidates for risk-
informed revisions; what are the bases for choosing these candidates; 
and what are the proposed changes to these candidate regulations?
    For example:
     Requirements result in unnecessary regulatory burden
     Additional requirements needed
     Requirements not commensurate with safety significance
     Risk-significant SSCs not covered by regulation
    2. Are the problems with the regulations themselves or with their 
implementation (e.g., regulatory guides, standard review plans, branch 
technical positions)?
    3. Are any of the regulations inconsistent or contradictory with 
other regulations? If so, where and which ones?
    4. Is the current set of design basis accidents appropriate, are 
any modifications needed? If so, what are the needed modifications?
    5. Are the principles stated in RG 1.174 appropriate in developing 
risk-informed revisions to Part 50?
    6. What level of risk should be the basis for risk-informed 
regulatory change?
    7. What should be the risk metrics and criteria?
