Japan to release ALPS‑treated water, not nuclear wastewater

Question asked:

“The water that Japan plans to release from the Fukushima plant is ALPS-treated water, not nuclear wastewater.”
Partially false
Confidence: High Checked on September 20, 2026

Summary

Japan’s release consists of water that has been processed through the ALPS system to remove most radioactive contaminants, but it remains nuclear wastewater containing tritium and other radionuclides. Thus, while the water is ALPS‑treated, it is still classified as nuclear wastewater.

The plan has met a mixed reaction, with support from some corners and skepticism from others. The US has backed Japan, and nearby Taiwan has agreed that the amount of tritium being released should have “minimal” impact.
