One Quarter Fukushima Upd !link! Jun 2026

Fukushima N-Plant Begins Treated Water Discharge for FY 2026. ... Tokyo, April 2 (Jiji Press)--The disaster-crippled Fukushima No. nippon.com

Japan’s 30–40 year decommissioning plan has passed its first quarter in terms of time (years 1–10). Key achievements include fuel removal from Unit 4 spent fuel pool and beginning ice wall maintenance, though major challenges remain.

Modeling from the Tokyo University of Marine Science suggests that even after 30 years of continuous discharge, the tritium concentration in coastal waters will remain below 0.1% of the natural tritium background produced by cosmic rays. However, bioaccumulation in long-lived species like tuna or deep-sea fish has not been fully modeled over multi-decadal scales.

It has been 15 years since the Great East Japan Earthquake and the subsequent disaster at the Fukushima Daiichi Nuclear Power Plant. While the headlines have faded for some, the work on the ground is reaching a critical "one-quarter" milestone in its multi-decade decommissioning timeline.

Highly specialized robotics have now surveyed roughly one-quarter of the primary containment vessels (PCV) to map the location of molten fuel (corium).

In this update, we dive into the current state of the Fukushima Daiichi Nuclear Power Plant, the status of the surrounding communities, and what the future holds for the region. 1. Decommissioning Progress: The 25% Milestone
