Struggling to recover from the 2011 Fukushima nuclear crisis, Tokyo Electric Power Company Holdings Inc. is considering collaborating with other utilities to conduct regular checks of their nuclear power plants in order to cut costs, sources close to the matter said Wednesday.

The practice of performing joint checks would be based on the utility's restructuring plan, unveiled last May to revitalize its nuclear power business through cooperation with other electric power companies.

Tepco is seeking cooperation with utilities that have boiling-water reactors — the same type as those at Tepco plants — or companies that also operate nuclear reactors in the vicinity of its own nuclear plants.
