On Aug. 4, the Japanese government and the Tokyo Electric Power Company (TEPCO) began construction on the underwater tunnel that will be used to release treated water from the Fukushima nuclear power plant into the ocean. Their plan is to use the Advanced Liquid Processing System (ALPS) to reduce the amount of radioactive material in the contaminated water, after which the treated water would be released into the ocean.
