" DEBRIS PLUGGING OF EMERGENCY CORE COOLING SUCTION STRAIMERS" On May 11, 1993, NRC issued NRC Bulletin No. 93-02, "b: 3ris Plugging of Emergency Core Cooling Suction Strainers,"
notifying licensees of the potential loss of net positive suction head for the Emergency Core Cooling System (ECCS).
The bulletin directed the licensees to take the.following actions:
1.
Identify fibrous air filters or other temporary sources of fibrous material, not designed to withstand a Loss of Coolant Accident (LOCA), which are installed or stored in the primary containment.
2.
Take any immediate compensatory measures which may be required to assure the functional capability of the.ECCS, and 3.
Take prompt action to remove any such material.
BFN Unit 2 is currently in a refueling shutdown.
Accordingly, TVA has performed a walkdown of the drywell (i.e., primary containment) and has confirmed that there are no temporary fibrous-air filter or other sources of fibrous material not designed to withstand a LOCA prior to closure of the drywell for restart.
