Title	Irradiator Pool Water Exceeded Conductivity Limit
Event Description	The following is a synopsis of information received from the state of Nebraska via phone: This report is being made in accordance with the corresponding 10 CFR 36.83(a)(10) requirement if "Pool water conductivity exceeding 100 microsiemens per centimeter" occurs. On 6/22/22, the licensee began having problems with the irradiator pool heat exchanger and condenser. On 6/23/22, the licensee noticed that the pool water was cloudy and conductivity began to increase. Conductivity exceeded 20 microsiemens per centimeter and the licensee began investigating to determine the cause. On 6/26/22, the licensee identified that conductivity had exceeded 100 microsiemens per centimeter and found a pinhole sized leak in the heat exchanger that was leaking Freon and oil into the pool. The highest conductivity noted was 160 microsiemens per centimeter. The licensee is currently filtering the pool water. They are also working to have the heat exchanger replaced. There was no excess external radiation received by any workers.
