WASHINGTON, D.C. 20555 May 24, 1996 NRC INFORMATION NOTICE 96-33: ERRONEOUS DATA FROM DEFECTIVE THERMOCOUPLE

'RESULTS IN A FIRE

Addressees

All material and fuel cycle licensees that monitor temperature with

thermocouples.

Purpose

The U.S. Nuclear Regulatory Commission (NRC) is issuing this information

notice to alert addressees to an incident where a defective thermocouple

caused an evaporator to run at an excessively high temperature, resulting in a

fire. It is expected that recipients will review the information for applica- bility to their facilities and consider actions, as appropriate, to avoid

similar problems. However, suggestions in this information notice are not NRC

requirements; therefore, no specific action nor written response is required.

Description of Circumstances

On February 21, 1996, a licensee had a fire in the ventilation system of its

liquid waste process. The licensee's investigation determined that the fire

was caused by a type-J thermocouple manufactured with reverse polarity. The

type-J thermocouple was part of a Pulse Combustion Drier put into operation in

1985 to evaporate waste water. The drier operates with natural gas that

ignites inside the drier combustion chamber. Waste water is pumped into the

hot gases being expelled from the combustion chamber within an evaporation

cone. The temperature is controlled by regulating the amount of waste water

being fed into the system. This is based on temperature readings from a

thermocouple in the duct work.

The licensee had replaced the thermocouple with a spare unit while trouble- shooting a lead wire problem on February 15, 1996. The spare thermocouple was

found to have reverse polarity during a test run, and the licensee believed it

had corrected the problem by reversing the lead wire polarity at the

instrument. The system appeared to read correctly during a 10-minute test

run. However, approximately an hour into a full run the next day, the

temperature reading began to behave erratically. The temperature readings

dropped even though the actual temperature was increasing. By the time the

licensee identified the discrepancy, a fire had started in the dust collector- filter cartridges.

The defective type-J thermocouple was purchased in 1985 (as a spare part),

along with the Pulse Combustion Drier from Sonodyne Industries in Portland, Oregon. The thermocouple had been manufactured for Sonodyne Industries by

Industries) in East Greenwich, Rhode Island. The licensee reported that

Sonodyne Industries is out of business and Gulton Industries is no longer

manufacturing thermocouples.

Discussion

NRC is not aware of any other Sonodyne driers currently being used by NRC

licensees. Licensees that operate waste water evaporators or other heat- generating systems using thermocouples may wish to consider reviewing the

source of the thermocouples and testing the polarity of thermocouples in

stock.
