The town of Mihama in Fukui Prefecture approved a plan Wednesday to urge Kansai Electric Power Co. to build an interim storage facility for spent nuclear fuel in the municipality, even though the prefectural government and the utility oppose the idea.
The decision was made at an extra town assembly session in the morning.
Kepco operates three nuclear power plants in the town.
Mihama Mayor Jitaro Yamaguchi has said the town is willing to host the facility and that he would hold talks with Kepco regarding its construction after obtaining the town assembly's approval.
But Fukui Gov. Issei Nishikawa has insisted that the facility be built outside the prefecture, and Kepco has said it plans to find a site elsewhere.
