From International Business Times:
One of the ongoing problems with unclear non-proliferation efforts is what to do with nuclear material in the former Soviet Union. A group from Sandia National Laboratories recently completed a project in Kazakhstan, and took another step towards securing it.
A large cache of enriched nuclear fuel - some 13 metric tons -- was stored in a nuclear reactor in the port city of Aktau, on the Caspian seacoast. The reactor was a Soviet-era fast breeder reactor, designed to make nuclear fuel for both weapons and power plants. The reactor, which started operations in 1973, also provided 135 megawatts of electricity, 9 million gallons of water per day and steam for hot water and heating for Aktau. It was shut down by the Kazakh government in 1999.
