The trouble-plagued ALPS (Advanced Liquid Processing System) system, intended to filter radioactive substances from the water in holding tanks at the Fukushima cleanup site, has reportedly failed once again, causing a minor disruption in the leanup efforts.
The system was partially shut down last Saturday after calcium was discovered in one of its 3 lines. According to a TEPCO spokesperson, the cause is believed to have been a filter. The filters were replaced and the system restarted.
ALPS, which filters strontium and 61 other radioactive materials from the water, has yet to be fully operational.
