The Tokyo Electric Power Company is looking into why a system for decontaminating radioactive water at the Fukushima Daiichi plant is not working as expected, delaying resumption of the system’s full-scale operation.

The firm on Wednesday published data showing the amount of radioactive materials that had been removed from contaminated water during a test run of the US-made system.

The data show that density of Cesium-13 and Cesium-137 dropped to only one-100th of initial levels.

An earlier test run using water with a lower density of radioactivity showed a drop to about one-1000th.

The utility had said the system would begin full-scale operation in a couple of days.

TEPCO on Tuesday began reducing the amount of cooling water injected into the plant’s No. 1 to 3 reactors and is carefully monitoring changes in their temperatures.
