en.Wedoany.com Reported - Kansai Electric Power Co., Inc. announced on June 2 that it has completed the transport of new fuel assemblies for Ohi Nuclear Power Plant Unit 3 from Nuclear Fuel Industries, Ltd. The unit is a pressurized water reactor with a rated generating capacity of 1,180 MW and a rated thermal output of 3,423 MW.
The transport departed from Nuclear Fuel Industries, Ltd. in Kumatori-cho, Sennan-gun, Osaka Prefecture at 23:00 on June 1 and arrived at Ohi Nuclear Power Plant at 06:25 on June 2, using land transportation. A total of 24 new fuel assemblies were transported, loaded into 12 transport containers, with the transport material classified as Class A fissile transport material.
The transport container model is NFI-V, cylindrical in shape, with a total length of approximately 5 meters, an outer diameter of approximately 1 meter, and a total weight of approximately 3.8 tons (the container itself weighs approximately 2.4 tons), made of stainless steel. The transport material has been confirmed by the nuclear regulatory authority to comply with national safety standards. According to Article 59 of the Act on the Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors, the technical standards for Class A fissile transport materials require a surface dose equivalent rate not exceeding 2 mSv/h and a rate at 1 meter from the surface not exceeding 0.1 mSv/h. The container must pass multiple tests including water spray, free drop, compression, penetration, 9-meter drop, fire resistance, and immersion, ensuring integrity is not compromised under strict conditions and that a critical state is not reached.
Kansai Electric Power stated that sufficient safety measures were taken during transport, including vehicle loading and signage. In the event of an emergency, it will immediately contact relevant authorities such as fire departments, police, and local governments.
