Plants
AGENCY: Nuclear Regulatory Commission.
ACTION: Regulatory guide; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or Commission) is
issuing a revision to Regulatory Guide (RG) 1.160, ``Monitoring the
Effectiveness of Maintenance at Nuclear Power Plants.'' This guide
endorses Revision 4A to Nuclear Management and Resources Council
(NUMARC) 93-01, ``Industry Guideline for Monitoring the Effectiveness
of Maintenance at Nuclear Power Plants,'' which provides methods that
are acceptable to the NRC staff for complying with the provisions of
Title 10 of the Code of Federal
[[Page 30031]]
Regulations (10 CFR) 50.65, ``Requirements for Monitoring the
Effectiveness of Maintenance at Nuclear Power Plants,'' Part 50,
``Domestic Licensing of Production and Utilization Facilities.''
Revision 4 of NUMARC 93-01 provides enhanced clarity regarding scoping
non-safety related Systems, Structures and Components based on their
use in Emergency Operating Procedures, gives guidance on consideration
of fire risk in (a)(4) risk assessments, and provides enhanced
consistency in unavailability monitoring between the Maintenance Rule
and Reactor Oversight process by providing clarification to the
definition for monitoring of short term unavailability resulting from
periodic system or equipment realignments.
