Start Preamble

AGENCY:

Nuclear Regulatory Commission (NRC).

ACTION:

Solicitation of public comment.

SUMMARY:

The NRC is soliciting public comment on its Proposed Interim Staff Guidance (ISG) DC/COL-ISG-013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML090830488). The purpose of this ISG is to modify and provide Combined License (COL) and Design Certification (DC) applicants additional clarity and guidance for the application of Standard Review Plan (SRP) Sections 11.2 and 2.4.13 on the characterization of hydro geological properties of a site associated with the effects of accidental releases of radioactive liquid on existing or likely future uses of ground and surface water resources in meeting the requirements of Title 10 of the Code of Federal Regulations, Part 100 (10 CFR 100.10 or 100.20) and Appendix B to 10 CFR Part 20 on effluent concentration limits. This ISG would revise the staff guidance previously issued in March 2007 in the SRP NUREG-0080, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants,” Sections 11.2 and 2.4.13. These two SRP sections are not internally consistent in identifying acceptable criteria for assessing the consequences of accidental releases of radioactive materials, or in providing guidance to the staff and applicants to establish conditions for such releases and define acceptable assumptions to describe exposure scenarios and pathways to members of the public. The NRC staff issues DC/COL-ISGs to facilitate timely implementation of current staff guidance and to facilitate activities associated with review of applications for DCs and COLs by the Office of New Reactors. The NRC staff will also incorporate the approved DC/COL-ISG-013 into the next revision of the SRP and related guidance documents.
