New Technology Helps Fukushima Nuclear Reactor Meet Radionuclide Discharge Limits

Purolite reports non-detect levels of all 62 radionuclides at plant damaged in Japan earthquake

Purolite announced that it has been successful in achieving non-detect levels on all of the 62 radionuclides that exceed mandated discharge limits in the coolant water at the Tokyo Electric (TEPCO) Fukushima Daiichi Nuclear Reactor in Japan.

“In conjunction with our Japanese partner, we have been able to demonstrate the successful reduction of all 62 radionuclides in the contaminated water to non-detect levels set by TEPCO,” said Steve Brodie, president and CEO of Purolite. “Investigation and testing encompassed six months of intense activity, culminating in pilot testing at the Fukushima site, which demonstrated that a combination of our new ion exchange products and innovative application techniques selectively reduced all radioactive nuclides to non-detect levels. This has never before been achieved, especially considering the high salt background level in the coolant water deriving from the use of seawater for emergency cooling a year ago.”

Achieving non-detect levels on all 62 radionuclides is critical to the local community, fishermen, farmers, neighboring countries and governmental bodies in order to safely discharge the cleaned water to the ocean. If any of the radionuclides are not reduced to non-detect levels, TEPCO may be forced to build more storage tanks until a satisfactory solution can be found.
