Document Action Status B 92-001 Failure of Thermo-Lag 330 Fire Barrier System to Maintain Cabling in Wide Cable Trays and Small Conduits Free From Fire Damage No Action Required (C)
This bulletin was provided for information only to plants with construction permits.
See Generic Letter 92-08 for Thermo-lag related actions.
GL 82-028 Inadequate Core Cooling Instrumentation System Unit 2 Action: Install Westinghouse Common Q PAM system. (CI)
LICENSE CONDITION -
Detectors for Inadequate core cooling (II.F.2) In the original SER, the review of the ICC instrumentation was incomplete.
The January 24, 1992, letter superseded the previous responses on this issue. TVA letter for Units 1 and 2 dated January 24, 1992, committed to install Westinghouse ICCM-86 and associated hardware. NRC completed the review for Units 1 and 2 in SSER10.
For Unit 2 due to obsolescence of the ICCM-86 system, TVA intends to install the Westinghouse Common Q Post-Accident Monitoring System.
