Water filtration at Fukushima halted after five hours

An effort to clean radioactively contaminated water at the Fukushima nuclear plant had to be halted after just five hours. TEPCO said it suspended the operation after part of the system that absorbs radioactive cesium had reached its processing capacity and needed to be replaced far earlier than expected. Water uncontaminated with cesium is needed to cool the still out-of-control reactors.
