On the 2nd of September, 2021, Tepco announced the exhaust filters attached to the contaminated water processing system were breached. The processing system is ALPS (Advanced Liquid Processing System). The operation is suspended until Tepco defines all the damaged parts of the filters and completes replacement.

Nine days earlier, the radiation monitor alarm sounded during the transferring process of the byproduct slurry from ALPS. After the inspections, Tepco confirmed the absorption filters of radioactive substances had at least 10 breaches. There are 25 filters in total.

The spokesman of Tepco commented ALPS is expected to restart soon and there is no significant effect on the contaminated water processing.
