IRRADIATOR POOL WATER CONDUCTIVITY EXCEEDS LIMIT

During a routine surveillance, oil was seen in the pool with the underwater irradiator. Testing found that the pool's conductivity was 180 micro Siemens per centimeter (æS/cm), exceeding the 20 æS/cm regulatory limit and the 100 æS/cm reportability limit. The licensee is currently filtering the water to clean up the pool and at the time of the notification had lowered the conductivity to 160 æS/cm. Additional filters are being purchased and the licensee estimates a few more days before the conductivity will be below the regulatory limit.

A leaking chiller was identified as the source of the oil. An assessment is being conducted to either repair or replace the chiller.
