CALCON TEMPERATURE SENSORS Model No. A3500-W3 o- On ' March 20, 1990, with one of two emergency diesel generators for Unit I tagged out and undergoing an alternate end of cycle checkout, ,

Vogtle Electric Generating Plant declared a site area emergency due to '

loss of offsite A/C power concurrent with a loss of onsite emergency diesel generator capability when the second emergency diesel generator  :

started, but tripped after appro>imately 1 minute 20 seconds.

o After a review of alarms and test runs on the emergency ' diesel, it was determined that the diesel failed to run because two of- three Calcon temperature sensors monitoring jacket water temperature were tripped.

The design of the diesels is to trip on two of three jacket water temperature sensors >2000F in all modes of operations.

o Wyle Laboratories, Huntsville, Alabama, was enntracted to perform Reliability Testing on the Calcon temperature sensors.

The testing at Wyle was completed in two phases. Phase ! was to determine the reliability of two new sensors. Phase II testing was to determine the' >

condition of eight sensors removed from service on the Unit I diesels. '

o c.  ;

I PHASE 1 TESTING AT WYLE LABORATORIES A complete battery of tests were performed on ten sensors at Wyle Labs introducing several variables (parameters). The tests were performed in order to determine what effect variables would have upon the temperature sensor operation and calibration of the Calcon A3500-W3 temperature  ;

sensors. The tests demonstrated that the following variables have no l significant effect on temperature sensor operation and calibration: '

o input air pressure variations of +5, -5 psi, o a rapid water temperature decrease (approximately 100F/ minute) from just below the setpoint, o vibration typical of in-service vibration (excluding long-term effects),

o ambient air temperature variations of -200F to +200F.

The following paragraphs describe parameters that were shown to have a l significant effect on the operation and/or calibration of the Temperature Sensor.

O Insufficient Temoerature Stabilization Period Prior to Calibration Consecutive calibration checks indicated a slight upward shift in the setpoint, apparently due to the failure to completely stabilize the temperature of all components of the specimens prior to the initial calibration. It was concluded that a minimum two-hour soak per'oc at approximately 2000F prior to calibration (1800F for setpoint checks) is necessary to ensure consistent performance. The Plant Calibration Procedure was changed to use 1650F as the soak temperature.

O Contaminants on the Temoerature Sensor Tests performed with the sensors removed from their thermowells and inserted directly in the water bath caused a downward shift of approximately 100F in the setpoint of the sensors, apparently due to mineral residue on the Viton 0-ring / disk assembly (standard facility water and not demineralized water was used in the water bath). The Viton 0-ring / disk assemblies were cleaned with Dow Corning 200 Fluid (silicone oil) and allowed to dry overnight. The sensors were then recalibrated and remained in calibration for the remainder of the tests. It was concluded that the sensors should not be immersed directly in water. All calibrations and tests should be performed with the sensors installed in their thernowells.

l A slow water bath.heatup rate (approximately 10F/ minute) was shown to 1 allow the thermowell internal temperature to , more closely follow the i water bath temperature. ;A. slow .heatup rate causes the' specimens ~to 'l trip at a higher temperature (as measured in'the thermowell): than a i fast heatup rate. It.should be noted that a slow heatup. rate.causes 1 the specimens to trip at a lower water temperature than a fast heatup. .

rate. ,

O Thermowell Setscrew Tiahtness  ;

The tests with the thermowell setscrews loose demonstrated that 'a. 1 loose setscrew causes an increase of approximately 20F.in the setpoint .i when measured with a heatup rate of 10F per minute. This setpoint. i shift is apparently due to the loss of contact between the. sensor and j

.the wall of the thermowell. :All calibrations and testing -should be' i performed with the thernowell-' setscrew tightened.

0 Soacer-Tube Position The tests performed.with the spacer-tubes loose demonstrated that the setpoint decreases approximately '800F for-each full turn. A1 thread-locking ~ compound is- recomunended to ensure: that the spacer-tube .

remains in its tightened position for all calibrations, tests, and in-service use.

O We have developed a new test procedure No.-22981-C which incorporates these results.

PHASE II TESTING Eight Calcon Temperature Sensors were removed from service at Vogtle and tested at WYLE Laboratories for cause of leaks, as-received setpoint and calibration repeatability.

The leak checks revealed that three sensors had air leaks through the seat area of the poppet valve at ambient temperature. Disassembly of these sensors revealed contaminants in the poppet seat area and other areas. The contaminants included threaded sealant material and metal slivers, apparently from the inlet air port threads. After removal of the contaminants and reassembly of the sensors, the leak checks were repeated and no leaks were found. One of the two new sensors tested in Phase I was also disassembled and inspected. Thread sealant material and metal slivers were found on the poppet port wall, on the spring, and in the air supply port.

The As-Received Setpoint Determination Tests revealed that the sensors had setpoints ranging from 1660F to 2000F (water bath temperature) with the exception of one sensor which would not trip.

All sensors were shown to be capable of being calibrated to trip at approximately 2000F 20F.
