GENKAI, Saga Pref. — The second of three deliveries of mixed uranium-plutonium oxide (MOX) fuel manufactured in France arrived at Kyushu Electric Power Co.'s Genkai No. 3 reactor in northern Saga Prefecture early Saturday morning.

If plans proceed on schedule, this plant on the Sea of Japan coast will see the country's first commercial use of the controversial fuel later this year.

Security was tight as a small flotilla of Japan Coast Guard ships escorted the Pacific Heron into the dock beside the plant. Heavy security checks were in place for all vehicles entering the main gate.
