Dear Sir:

' As per our telephone conversation of 28 July 1992 with Mr. Craig-Bassett relative to an unscheduled shutdown conducted due to loss ofindication/ input from the thermocouple

monitoring the_ water tempemture ;in the outlet of fuel box #2, we have concluded this occurrence is probably not a potentially reportable occurrence per UFTR Technical

' Specifications, Section 6.6.2 delineating requirements.for special reports. The RSRS Executive Committee (4 members) has agreed but recommended NRC notification as per Section 6.6.20f the UFTR Tech Specs though the event does not appear to be promptly reportable. depending on interpretation 'of the Tech Specs, bitial evaluation indicates 1

the problem is probably in the thermocoupie or connecting circuit in the high radiation field area at the outlet of fuel box #2 which will necessitate unstacking biological shielding for acass to correct the problem.
