NUCLEAR REGULATORY COMMISSION
Grid Reliability and the Impact on Plant Risk and the Operability
of Offsite Power
AGENCY: Nuclear Regulatory Commission.
ACTION: Notice of Issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) has issued
Generic Letter (GL) 2006-02 to all holders of operating licenses for
nuclear power reactors, except those who have permanently ceased
operation and have certified that fuel has been removed from the
reactor vessel. The NRC is issuing this generic letter to determine if
compliance is being maintained with NRC regulatory requirements
governing electric power sources and associated personnel training for
your plant, the NRC is issuing this GL to obtain information from its
licensees regarding:
1. Use of protocols between the nuclear power plant (NPP) and the
transmission system operator (TSO), independent system operator (ISO),
or reliability coordinator/authority (RC/RA) and the use of
transmission load flow analysis tools (analysis tools) by TSOs to
assist NPPs in monitoring grid conditions to determine the operability
of offsite power systems under plant technical specifications. (The
TSO, ISO, or RA/RC is responsible for preserving the reliability of the
local transmission system. In this GL the term TSO is used to denote
these entities);
2. Use of NPP/TSO protocols and analysis tools by TSOs to assist
NPPs in monitoring grid conditions for consideration in maintenance
risk assessments;
3. Offsite power restoration procedures in accordance with Section
2 of NRC Regulatory Guide (RG) 1.155, ``Station Blackout'';
4. Losses of offsite power caused by grid failures at a frequency
equal to or greater than once in 20 site-years in accordance with RG
1.155, and
5. Require addressees to provide a written response to the NRC in
accordance with 10 CFR 50.54(f).
This Federal Register notice is available through the NRC's
Agencywide Documents Access and Management System (ADAMS) under
accession number ML060380343.
DATES: The GL was issued on February 1, 2006.
