Ehime Prefecture announced on August 13, 2026, that a small amount of ash had leaked near the filter of an incineration device within the managed area of Shikoku Electric Power's Ikata Nuclear Power Station in Ikata-cho, the prefecture. The ash was fully recovered, and the prefecture stated that there is no impact on the environment or health.
The device is used to incinerate combustible low-level radioactive waste such as cloth scraps. Exhaust gas from the incinerator, along with fine ash, flows through the filter before being discharged from the stack. At around 10:30 a. m. on the 13th, an operator on patrol discovered a substance suspected to be ash, and subsequently confirmed a small crack in the container that collects ash inside the filter.
Shikoku Electric Power has halted operation of the incineration device and is investigating the details of the incident.
