Start Preamble

AGENCY:

Nuclear Regulatory Commission (NRC).

ACTION:

Solicitation of public comment.

SUMMARY:

The NRC staff is soliciting public comment on its proposed Interim Staff Guidance (ISG) DC/COL-ISG-021 titled “Interim Staff Guidance on the Review of Nuclear Power Plant Designs Using a Gas Turbine Driven Standby Emergency Alternating Current Power System,” (Agencywide Documents Access and Management System (ADAMS) Accession No. ML092640035). This ISG provides new guidance information for applicants submitting a combined license (COL) or design certification (DC) for construction and operation of new reactors submitted under Title 10 of the Code of Federal Regulations, Part 52. In addition, it supplements the guidance provided to the NRC staff in other sections of NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants,” March 2007, Standard Review Plan (SRP), Section 8.3.1 and Sections 9.5.4 through 9.5.8. 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 (NRO). The NRC staff intends to incorporate the final approved DC/COL-ISG-021 into the next revision of SRP Section 8.3.1 and Sections 9.5.4 through 9.5.8 and Regulatory Guide 1.206, “Combined License Applications for Nuclear Power Plants (LWR Edition),” June 2007.

Background: Emergency diesel generators are widely used as the standby emergency power sources for the onsite alternating current (AC) power system. It is anticipated that new reactor designs will incorporate gas turbines to supply the standby emergency alternating current power system. This ISG document provides guidance on the implementation of emergency gas turbine generators (EGTGs) used as AC power sources to supply power to safety-related equipment or equipment important to safety for all operational events and during accident conditions. Only EGTG systems that are air cooled and diesel oil fueled are considered in this interim guidance.

DATES:

Comments must be filed no later than 30 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:
