B. Submitting Comments
Please include Docket ID NRC-2013-0103 in the subject line of your comment submission, in order to ensure that the NRC is able to make your comment submission available to the public in this docket.
The NRC cautions you not to include identifying or contact information that you do not want to be publicly disclosed in your comment submission. The NRC will post all comment submissions at http://www.regulations.gov as well as enter the comment submissions into ADAMS. The NRC does not routinely edit comment submissions to remove identifying or contact information.
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 that they do not want to be publicly disclosed in their comment submission. Your request should state that the NRC does not routinely edit comment submissions to remove such information before making the comment submissions available to the public or entering the comment submissions into ADAMS.
Employing appropriate compensatory measures, on a short-term basis, is an integral part of NRC-approved fire protection programs. However, compensatory measures are not expected to be in place for an extended period of time. The NRC staff expects that the corrective action(s) will be completed, and reliance on the compensatory measure eliminated, at the first available opportunity, typically the first refueling outage. Thus, a compensatory measure that is in place beyond the next refueling outage (typically 18—24 months) is considered to be a “long-term compensatory measure.”
This report is intended to serve as a reference guide for agency staff responsible for evaluating the acceptability of alternative interim compensatory measures provided to offset the degradation in fire safety caused by impaired fire protection features at nuclear power plants. The report documents the history of compensatory measures and details the regulatory framework established by NRC to ensure they are appropriately implemented and maintained. This report also explores technologies that did not exist when the current plants were licensed such as video-based detection, temporary penetration seals and portable suppression systems which under certain conditions may provide an effective alternative to traditional measures specified in a plant's approved fire protection program.
The NRC is seeking public comment in order to receive feedback from the widest range of interested parties and to ensure that all information relevant to the information contained within this document is correct and accurate. We are specifically interested in receiving feedback on the following questions:
1. Do licensees differentiate between compensatory measures related to impaired structures, systems, and components (SSC) used for Reactor Post-Fire Safe-Shutdown Protection vs. impaired classical Fire Protection (FP) systems? If so, please provide information on the differences between the two.
2. Are there any other examples of Alternative Compensatory Measures (e.g. other new technology) not already discussed in the NUREG/CR that should be considered? If so, please provide information on these alternative compensatory measures.
3. Are there any issues, concerns or better suggestions regarding the examples or technologies discussed in the NUREG/CR? If so, please provide your suggestions.
This document is issued for comment only and is not intended for interim use. The NRC will review public comments received on the documents, incorporate suggested changes as necessary, and make the final NUREG-report available to the public.Start Signature
