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.
