Notice of opportunity for public comment.


The U.S. Nuclear Regulatory Commission (NRC) is requesting public comment on the proposed model safety evaluation (SE) for plant-specific adoption of Technical Specifications (TS) Task Force (TSTF) Traveler TSTF-510, Revision 2, “Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection.” TSTF-510, Revision 2, is available in the Agencywide Documents Access and Management System (ADAMS) under Accession Number ML110610350, and includes a model application. The proposed change revises the Improved Standard Technical Specification (ISTS), NUREGs-1430, -1431, and -1432, Specification 5.5.9, “Steam Generator (SG) Program,” 5.6.7, “Steam Generator Tube Inspection Report,” and the SG Tube Integrity specification (Limiting Condition for Operation (LCO) 3.4.17, LCO 3.4.20, and LCO 3.4.18 in ISTS NUREG-1430, -1431, and -1432, respectively). The proposed changes are necessary to address implementation issues associated with the inspection periods, and address other administrative changes and clarifications. The model SE will facilitate expedited approval of plant-specific adoption of TSTF-510, Revision 2. This TS improvement is part of the consolidated line item improvement process (CLIIP).


The comment period expires on July 20, 2011. 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.


You may submit comments by any one of the following methods. Please include Docket ID NRC-2011-0136 in the subject line of your comments. Comments submitted in writing or in electronic form will be posted on the NRC Web site and on the Federal rulemaking Web site Because your comments will not be edited to remove any identifying or contact information, the NRC cautions you against including any information in your submission that you do not want to be publicly disclosed.

The NRC requests that any party soliciting or aggregating comments received from other persons for submission to the NRC inform those persons that the NRC will not edit their comments to remove any identifying or contact information, and therefore, they should not include any information in their comments that they do not want publicly disclosed.

TSTF-510, Revision 2, is applicable to pressurized water reactor plants. The proposed changes revise the ISTS to implement a number of editorial corrections, changes, and clarifications intended to improve internal consistency, consistency with the implementing industry documents, and usability without changing the intent of the requirements. The proposed changes to Specification 5.5.9.d.2 are more effective in managing the frequency of verification of tube integrity and sample selection than those required by current technical specifications. As a result, the proposed changes will not reduce the assurance of the function and integrity of SG tubes. TS Bases changes that reflect the proposed changes are included.

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 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-510, Revision 2. 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-510, Revision 2.
