###### Nuclear Regulatory Commission

# 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-06 (ADAMS Accession No. ML081850160). This ISG is to clarify the U.S. Nuclear Regulatory Commission (NRC) position on what is an acceptable level of detail and content for demonstrating compliance with Title 10 of the                         *Code of Federal Regulations*                         Section 20.1406 (10 CFR 20.1406). Regulatory Guide (RG) 4.21, “Minimization of Contamination and Waste Generation: Life Cycle Planning,” provides an acceptable method of demonstrating compliance. This ISG provides further clarification on the evaluation and acceptance criteria that will be used by NRC staff in reaching a reasonable assurance finding that a Design Certification (DC) or Combined License (COL) applicant has complied with the requirements of 10 CFR 20.1406. The NRC staff issues DC/COL-ISGs to facilitate timely implementation of the current staff guidance and to facilitate activities associated with review of applications for DC and COLs by the Office of New Reactors. The NRC staff will also incorporate the approved DC/COL-ISG-006 into the next revision of the Standard Review Plan and related guidance documents.
