The U.S. Nuclear Regulatory Commission (NRC) has issued a draft new appendix to a guide in its Regulatory Guide series. This series has been developed to describe and make available to the public such information as methods acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques used by the staff in its review of applications for permits and licenses, and data needed by the NRC staff in its review of applications for permits and licenses.
The NRC has issued for comment draft Regulatory Guide DG-1138, which is a preliminary draft of the staff's regulatory position on ANSI/ANS 58.21-2003, “External Events PRA Methodology Standard.” The staff's position is documented in Appendix C, “NRC Staff Regulatory Position on ANS External Hazards PRA Standard” to Regulatory Guide 1.200, “An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-Informed Activities.” Regulatory Guide 1.200 was issued for trial use in February 2004 and did not contain Appendix C. The NRC staff is only soliciting comments on Appendix C to RG 1.200; Appendix C has not been issued for use. It is the staff's intent to issue a draft Revision 1 to RG 1.200 with Appendix C for public review and comment before issuing Revision 1 to RG 1.200 as final for use in mid-2005.
The NRC staff is soliciting comments on draft Appendix C. Comments may be accompanied by relevant information or supporting data. Please mention DG-1138 in the subject line of your comments. Comments on regulatory guides submitted in writing or in electronic form will be made available to the public in their entirety on the NRC rulemaking Web site.

The NRC intends to conduct a workshop on November 9, 2004, to be held in the auditorium at NRC headquarters, 11545 Rockville Pike, Rockville, Maryland, (the agenda will be announced in a future public notice), to discuss and explain the staff's position on the ANS standard, and the staff's response to the public comments received. In the workshop, the staff will discuss each public comment and the basis for the staff's position, and answer questions.
