If you are requesting or aggregating comments from other persons for submission to the NRC, then you should inform those persons not to include identifying or contact information in their comment submissions that they do not want to be publicly disclosed. Your request should state that the NRC will not edit comment submissions to remove such information before making the comment submissions available to the public or entering the comment submissions into ADAMS.

Background

The proposed change revises the Improved Standard Technical Specification (ISTS), NUREG-1430, “Standard Technical Specifications Babcock and Wilcox Plants,” NUREG-1431, “Standard Technical Specifications Westinghouse Plants,” NUREG-1432, “Standard Technical Specifications Combustion Engineering Plants,” NUREG-1433, “Standard Technical Specifications General Electric Plants BWR [Boiling Water Reactor]/4,” and NUREG-1434, “Standard Technical Specifications General Electric Plants, BWR/6.” Specifically, the proposed change revises Surveillance Requirements (SRs) for the following systems: The iodine cleanup system/shield building air cleanup system, the control room emergency filtration system, the emergency core cooling system (ECCS) pump room exhaust air cleanup system, and the fuel building air cleanup system. This TS improvement is part of the consolidated line item improvement process (CLIIP).

Additional Technical Details

TSTF-522, Revision 0, is applicable to all nuclear power plants. The proposed change revises SRs for the following systems: The iodine cleanup system/shield building air cleanup system, the control room emergency filtration system, the ECCS pump room exhaust air cleanup system, and the fuel building air cleanup system. In particular SRs 3.6.11.1/3.6.13.1, 3.7.10.1, 3.7.12.1, 3.7.13.1, and 3.7.14.1, which currently require operating the heaters in the respective systems for at least 10 continuous hours every 31 days, would be changed to require at least 15 continuous minutes of heater operation every 31 days.

This notice provides an opportunity for the public to comment on proposed changes to the ISTS after a preliminary assessment and finding by the NRC staff that the agency will likely offer the changes for adoption by licensees. This notice solicits comment on proposed changes to the ISTS, which if implemented by a licensee will modify the plant-specific TS. The NRC staff will evaluate any comments received for the proposed changes and reconsider the changes or announce the availability of the changes for adoption by licensees as part of the CLIIP. Licensees opting to apply for this TS change are responsible for reviewing the NRC staff's SE, and the applicable technical justifications, providing any necessary plant-specific information, and assessing the completeness and accuracy of their license amendment request (LAR). The NRC will process each amendment application responding to the notice of availability according to applicable NRC rules and procedures.

The proposed changes do not prevent licensees from requesting an alternate approach or proposing changes other than those proposed in TSTF-522, Revision 0. However, significant deviations from the approach recommended in this notice or the inclusion of additional changes to the license require additional NRC staff review. 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-522, Revision 0.

Dated at Rockville, Maryland, this 14th day of March 2012.

For the Nuclear Regulatory Commission.

John R. Jolicoeur,

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