Japan Advances Nuclear Waste Plans: Genkai Earmarks Survey Grant, Kaminoseki Deemed Viable, Kansai Sets 2035 Fuel Transfers

Grant incentives for surveys, coupled with shrinking pool capacity, are pushing projects from study to scheduling.

Overview

  • Genkai Town in Saga Prefecture decided to use ¥1 billion from the FY2025 national survey grant to build a three‑story crisis‑management building at the town hall site, targeting service in FY2028.
  • The town will submit related measures to its September assembly; the basic design, totaling about 2,000 square meters with a permanent emergency headquarters and server room, was prepared in FY2024.
  • Japan’s literature‑survey grant program can provide up to ¥20 billion across FY2025–26, with more than half flowing to participating municipalities and the remainder shareable with prefectures or nearby towns.
  • Chugoku Electric reported to Yamaguchi Prefecture’s Kaminoseki Town that geological work and other checks concluded the proposed off‑site interim storage location is siting‑possible, citing no signs of giant tsunami impacts or active faults.
  • Kansai Electric informed Fukui Prefecture it plans to start moving spent fuel to an off‑site interim storage facility by the end of 2035, as reactor pool space nationwide is roughly 80% utilized and Kaminoseki would become only the second off‑site storage site after Mutsu if built.
