Ikata Nuclear Power Station Reports 5 Notifiable Events in July, None Causing Radiological Environmental Impact
Shikoku Electric Power Co. reported on August 10 that the five events reported to Ehime Prefecture, Ikata Town, and relevant local governments from the Ikata Nuclear Power Station in July 2026 did not fall under legally required reporting events and caused no radiological impact on the environment. The five events were as follows: On July 3, an employee of a partner company at the Ikata Nuclear Power Station experienced physical discomfort at an office location in a non-controlled area and was transported by ambulance at 17:18 that day. The employee was conscious at the time and experienced no radiation exposure or radioactive contamination. On July 16, during the decommissioning process of Unit 2 at the Ikata Nuclear Power Station, seawater leakage was discovered at the flange of the seawater outlet pipe of emergency diesel generator 2B in the reactor auxiliary building. After maintenance personnel determined that a detailed inspection of the flange was required, the leak point was isolated, and the leakage was confirmed to have stopped at 15:38 that day. The maximum estimated volume of leaked seawater was approximately 7 cubic meters, all of which was recovered in the floor drain sump within the building and did not flow outside. Subsequent inspection revealed a through-hole approximately 7 mm in diameter at the flange, and the station replaced the flange and confirmed water flow integrity, restoring normal conditions at 14:05 on July 17. This event did not affect the unit or cause radiological environmental impact, and further investigation into the cause will be conducted.
