NUCLEAR REGULATORY COMMISSION

10 CFR Part 50

RIN 3150-AF95


Monitoring the Effectiveness of Maintenance at Nuclear Power 
Plants; Confirmation of Effective Date and Availability of Guidance

AGENCY: Nuclear Regulatory Commission.

ACTION: Final rule: Confirmation of effective date and availability of 
guidance.

-----------------------------------------------------------------------

SUMMARY: The Nuclear Regulatory Commission amended its regulation 
concerning requirements for monitoring the effectiveness of maintenance 
at nuclear power plants on July 19, 1999 (64 FR 38551). The effective 
date of this amendment was deferred until guidance on assessing and 
managing increases in risk associated with maintenance activities was 
issued to nuclear power plant licensees. This document announces the 
availability of that guidance (Regulatory Guide 1.182, ``Assessing and 
Managing Risk Before Maintenance Activities at Nuclear Power Plants'') 
and specifies the effective date for the July 19, 1999, amendment to 
the maintenance rule.

EFFECTIVE DATE: November 28, 2000.

ADDRESSES: Regulations, certain regulatory guides, and certain endorsed 
NUMARC documents are available for inspection or downloading at the 
NRC's web site, WWW.NRC.GOV>. Single copies of regulatory guides may be 
obtained free of charge by writing the Reproduction and Distribution 
Services Section, U.S. Nuclear Regulatory Commission, Washington, DC

SUPPLEMENTARY INFORMATION:

Background

    The Nuclear Regulatory Commission amended its maintenance rule, 10 
CFR 50.65, ``Requirements for monitoring the effectiveness of 
maintenance at nuclear power plants,'' on July 19, 1999 (64 FR 38551). 
This amendment requires nuclear power plant licensees to assess and 
manage the increase in risk that may result from proposed maintenance 
activities. The implementation date of this amendment was made 
dependent upon guidance being issued to nuclear power plant licensees 
on assessing and managing increases in risk associated with maintenance 
activities.
    Rather than issue Revision 3 to Regulatory Guide 1.160, 
``Monitoring the Effectiveness of Maintenance at Nuclear Power 
Plants,'' the NRC staff decided to issue Regulatory Guide 1.182, 
``Assessing and Managing Risk Before Maintenance Activities at Nuclear 
Power Plants,'' as guidance to nuclear power plant licensees on 
assessing and managing risk before maintenance activities are conducted 
at the nuclear power plant. Regulatory Guide 1.182 is being issued as a 
companion guide to Regulatory Guide 1.160, which provides guidance on 
the structure of the licensees' maintenance effectiveness monitoring 
programs.
    Regulatory Guide 1.160 endorses a document prepared by the Nuclear 
Energy Institute (formerly NUMARC), NUMARC 93-01, ``Industry Guideline 
for Monitoring the Effectiveness of Maintenance at Nuclear Power 
Plants.'' Regulatory Guide 1.182 endorses a revised Section 11, 
``Assessment of Risk Resulting from Performance of Maintenance 
Activities,'' of NUMARC 93-01. Regulatory Guide 1.182 was published for 
public comment (64 FR 70098, December 15, 1999) as DG-1082, ``Assessing 
and Managing Risk Before Maintenance Activities at Nuclear Power 
Plants.'' There were no public comments on the draft guide, and NEI 
addressed the comments on Section 11 of NUMARC 93-01 with minor 
revisions, and the NRC staff concurs in these revisions.
    Therefore, the effective date of the July 19, 1999, amendment to 10 
CFR 50.65 is November 28, 2000.

    Dated at Rockville, Maryland, this 26th day of May, 2000.

    For the Nuclear Regulatory Commission.
J. Samuel Walker,
Acting Secretary of the Commission.
