Nuclear Safety: International Assistance Efforts to Make Soviet-Designed Reactors Safer, Report to Congressional Requesters [open pdf - 2MB]
"As of May 1994, about $785 million had been pledged to implement the G7 assistance plan, primarily for improving the safety of the Soviet-designed civil nuclear power reactors located in the former Soviet Union and in central and eastern Europe. A longer-term goal of the assistance program is to shut down the most dangerous nuclear power reactors and replace them with alternative energy sources. The plan also calls for improving nuclear regulatory agencies in those countries operating Soviet-designed reactors. As of May 1994, only about 7 percent of the projects, worth about $57 million, had been completed."
