OSAKA — In the wake of a scandal involving British Nuclear Fuels PLC, Kansai Electric Power Co. said Wednesday that it will step up efforts to monitor the quality of plutonium fuel manufactured by foreign companies for use in its nuclear power plants.

Releasing its final report on the scandal, KEPCO said it will strengthen monitoring both at facilities where mixed uranium-plutonium oxide fuel (MOX) is produced and at the company's headquarters in Osaka.

The report did not touch on the issue of what to do with the tainted MOX fuel rods that have been sitting at the No. 4 reactor in Takahama, Fukui Prefecture, since being delivered from Britain in September last year.
