anges in costs or benefit to the public, licensees or NRC. However, the “no-action” alternative would not address identified concerns with the current lack of guidance. This alternative provides a baseline condition from which any other alternatives will be assessed. Alternative 2: Issue a Regulatory Guide Endorsing IEEE Standard 334-2006 Preparing and issuing the revised regulatory guide will provide the industry with clearer guidance and understanding of the methodology the NRC staff will use to establish the basic principles, and methods of qualifying safety-related motors for applications in both harsh and mild environments in nuclear power plants. IEEE Standard 334-2006 is an acceptable standard which reflects the current state of technology. The technical approach discussed in the revised standard is consistent with the NRC’s regulatory requirements. The impact to the NRC would be the costs associated with preparing and issuing the regulatory guide. The impact to the public would be the voluntary costs associated with reviewing and providing comments to NRC during the public comment period. The value to NRC staff and its applicants would be the benefits associated with enhanced efficiency and effectiveness in using a common guidance document as the technical basis for license applications and other interactions between the NRC and its regulated entities. Conclusion The NRC should revise this regulatory guide to enhance the licensing process. The staff has concluded that the proposed action will reduce unnecessary burden on both the NRC and its licensees and will result in an improved and more uniform process for qualifying safety-related motor control centers. Moreover, the staff sees no adverse effects associated with issuing this regulatory guide.
