Interim Staff Guidance on Assessing the Consequences of an 
Accidental Release of Radioactive Materials From Liquid Waste Tanks

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.

DATES: Comments must be filed no later than 60 days from the date of 
publication of this notice in the Federal Register. Comments received 
after this date will be considered, if it is practical to do so, but 
the Commission is able to ensure consideration only for comments 
received on or before this date.

ADDRESSES: Comments may be submitted to: Chief, Rulemaking and 
Directives Branch, Office of Administration, Mail Stop: TWB-05-B01M, 
U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, and 
should cite the publication date and page number of the Federal 
Register notice.
