Inaccessible or Underground Power Cable Failures That Disable 
Accident Mitigation Systems or Cause Plant Transients

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of Issuance.

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) has issued 
Generic Letter (GL) 2007-01 to all holders of operating licenses for

affect the functionality of multiple accident mitigation systems or 
cause plant transients,
    (2) Inform licensees that in the absence of adequate monitoring of 
cable insulation, equipment could fail abruptly during service, causing 
plant transients or disabling accident mitigation systems,
    (3) Ask licensees to provide information on the monitoring of
