2010-30490. Notice of Availability of the Models for Plant-Specific Adoption of Technical Specifications Task Force (TSTF) Traveler TSTF-431, Revision 3, “Change in Technical Specifications End States (BAW-2441)”

AGENCY:

Nuclear Regulatory Commission (NRC).

ACTION:

Notice of availability.

SUMMARY:

As part of the consolidated line item improvement process (CLIIP), the NRC is announcing the availability of the model application (with model no significant hazards consideration (NSHC) determination) and model safety evaluation (SE) for the plant-specific adoption of Technical Specifications Task Force (TSTF) Traveler TSTF-431, Revision 3, “Change in Technical Specifications End States (BAW-2441).” TSTF-431, Revision 3, is available in the Agencywide Documents Access and Management System (ADAMS) under Accession Number ML093570241. The proposed changes revise the Standard Technical Specifications (STS) to permit, for some systems, entry into a hot shutdown (Mode 4) end state rather than a cold shutdown (Mode 5) end state. These changes are associated with the implementation of Topical Report BAW-2441-A, Revision 2, “Risk-Informed Justification for LCO End-State Changes.” The CLIIP model SE will facilitate expedited approval of plant-specific adoption of TSTF-431, Revision 3.

Mr. Ravi Grover, Reactor Systems Engineer, Technical Specifications Branch, Mail Stop: O-7C2A, Division of Inspection and Regional Support, Office of Nuclear Reactor Regulation, U.S. Nuclear Regulatory Commission, Washington, DC, 20555-0001; telephone [phone] or e-mail at [e-mail] or Ms. Michelle C. Honcharik, Senior Project Manager, Licensing Processes Branch, Mail Stop: O-12 D1, Division of Policy and Rulemaking, Office of Nuclear Reactor Regulation, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; telephone [phone] or e-mail at [e-mail].

SUPPLEMENTARY INFORMATION:

TSTF-431, Revision 3, is applicable to Babcock & Wilcox reactor plants. Licensees opting to apply for this TS change are responsible for reviewing TSTF-431, Revision 3, and the NRC staff's SE, providing any necessary plant-specific information, and assessing the completeness and accuracy of their license amendment request (LAR). It is acceptable for licensees to use plant-specific system names, TS numbering and titles. The NRC will process each amendment application responding to this notice of availability according to applicable NRC rules and procedures.

The models do not prevent licensees from requesting an alternate approach or proposing changes other than those proposed in TSTF-431, Revision 3. However, significant deviations from the approach recommended in this notice or the inclusion of additional changes to the license require additional NRC staff review and would not be reviewed as a part of the CLIIP. This may increase the time and resources needed for the review or result in NRC staff rejection of the LAR. Licensees desiring significant deviations or additional changes should instead submit an LAR that does not claim to adopt TSTF-431, Revision 3.

Dated at Rockville, Maryland, this 23rd day of November 2010.

For the Nuclear Regulatory Commission,

John R. Jolicoeur,

Chief, Licensing Processes Branch, Division of Policy and Rulemaking, Office of Nuclear Reactor Regulation.
