Furthermore, radiation levels across Fukushima continue to fall. As of June 2026, the secretariat of the Nuclear Regulation Authority stated that radiation levels are now around the national average in .
Here’s a write-up based on the phrase — interpreted as a reference to the Fukushima Daiichi nuclear disaster (March 2011) and possibly an update or status report indicating that one quarter (25%) of something related to the site has been addressed, completed, or changed.
Strategy shifted to South-side fuel removal; full retrieval delayed to 2037. one quarter fukushima upd
On , TEPCO officially launched its first round of ALPS-treated water discharge for the new fiscal year. This marks the 19th round overall since the process began in 2023.
In late February 2025, TEPCO initiated the sixth batch of treated water release, marking the start of a new fiscal cycle. As of this "one quarter" update (late May 2025), approximately 58,000 cubic meters of ALPS-treated water have been discharged into the Pacific Ocean since the program began in August 2023. The latest three-month cycle alone accounted for roughly 7,800 metric tons—slightly less than the planned 8,000 due to weather delays. Strategy shifted to South-side fuel removal; full retrieval
Focus remains on debris removal and preparing for fuel retrieval. The site faces structural challenges, requiring specialized robotic solutions for assessing the damage within the reactor building.
Since the controversial release of treated water began, independent analyses, including reports from the China Atomic Energy Authority In late February 2025, TEPCO initiated the sixth
One practical success of this quarter: TEPCO repurposed 42 of the original 1,000+ storage tanks for rainwater storage and decommissioning equipment. As of June 1, 2025, only 89% of the site’s tank area remains occupied, down from 96% at the start of the year. At the current release rate of one quarter of the annual volume (approx 30,000 tons per quarter), TEPCO estimates all tanks will be emptied by early 2030.
Driven by an unprecedented $200 billion containment effort, the region has transformed from a strictly controlled exclusion zone into a dynamic hub for robotics, green energy, and community reclamation. Yet, the remaining roadmap spans another 25 to 30 years, facing formidable engineering hurdles in fuel debris extraction and long-term nuclear waste management. Technical Baseline: The Three Meltdowns
