## II. Additional Information

The NRC is issuing for public comment a DG in the NRC's “Regulatory Guide” series. This series was developed to describe methods that are acceptable to the NRC staff for implementing specific parts of the agency's regulations, to explain techniques that the staff uses in evaluating specific issues or postulated events, and to describe information that the staff needs in its review of applications for permits and licenses.

The DG, entitled “Guide for Assessing, Monitoring, and Mitigating Aging Effects on Electrical Equipment Used in Nuclear Power Generating Stations,” is a proposed new Regulatory Guide 1.248 and is being issued with a temporary identification of Draft Regulatory Guide, DG-1393.

                    Nuclear power plants (NPPs) licensed under Parts 50 and 52 of title 10 of the                     *Code of Federal Regulations*                     (10 CFR), are required to monitor the performance or condition of Structures, Systems and Components (SSCs) against licensee-established goals, in a manner sufficient to provide reasonable assurance that these SSCs can fulfill their intended functions. Further, applicants for and holders of NPP renewed licenses under 10 CFR part 54 are required to demonstrate that the effects of aging will be adequately managed for the period of extended operation. DG-1393 describes a method that the NRC staff considers acceptable in complying with NRC regulations for assessing, monitoring, and mitigating aging effects on electrical equipment in NPPs.                

## III. Backfitting, Forward Fitting, and Issue Finality

Issuance of DG-1393, if finalized, would not constitute backfitting as that term is defined in 10 CFR 50.109, “Backfitting,” and as described in NRC Management Directive (MD) 8.4, “Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests”; would not constitute forward fitting as that term is defined and described in MD 8.4; and would not affect issue finality of any approval issued under 10 CFR part 52, “Licenses, Certificates, and Approvals for Nuclear Power Plants.” As explained in DG-1393, applicants and licensees are not required to comply with the positions set forth in DG-1393.
