Start Preamble

AGENCY:

Nuclear Regulatory Commission.

ACTION:

Notice of public workshop.

SUMMARY:

The Nuclear Regulatory Commission has instructed its staff to explore changes to specific technical requirements of 10 CFR part 50, to incorporate risk-informed attributes. The staff is studying the ensemble of technical requirements contained in 10 CFR part 50 (and its associated implementing documents, such as regulatory guides and standard review plan sections) to (1) identify individual or sets of requirements potentially meriting change; (2) prioritize which of these requirements (or sets of requirements) should be changed; and (3) develop the technical bases to an extent that is sufficient to demonstrate the feasibility of changing the requirements. This work will result in recommendations to the Commission on specific regulatory changes that should be pursued. Public participation in the development of these recommendations will be obtained via workshops, information on a web site, and other means.

SUPPLEMENTARY INFORMATION:

This notice serves as notification of a public workshop to provide for the exchange of information with all stakeholders regarding the staff's efforts to risk-inform the technical requirements of 10 CFR part 50. The subject of the workshop will be to discuss the preliminary work being performed by the NRC staff on risk-informing the technical requirements of 10 CFR part 50. The meeting will focus on the overall framework of the risk-informing process, the criteria used to identify and Start Printed Page 7076prioritize candidate regulations and design basis accidents (DBAs), the results of the staff's initial efforts in risk-informing two trial implementation issues (i.e., 10 CFR 50.44 and special treatment rules), the preliminary results of the selection of additional candidate requirements and DBAs to be examined, and discussion of preliminary issues associated with the development and implementation of the entire process.

Initial documents covering some of the above topics will be available on the part 50 technical requirements web site between one and two weeks prior to the workshop and will be placed in the public document room. Each of these documents will contain a list of preliminary issues for discussion. The address for the Part 50 technical requirements web site is as follows: http://nrc-part50.sandia.gov This web site can also be accessed from the NRC web site (http://www.nrc.gov), by selecting “Nuclear Reactors,” and then “Risk-Informed Part 50 (Option 3).”

The part 50 technical requirements web site currently contains some pertinent background information, located under the “Related Sites” page (e.g., SECY-98-300, SECY-99-256 and SECY-99-264).
