The USA reported its actions since the Chornobyl Disaster

U.S. Embassy in Ukraine distributed a press release “United States Technical/ Social/Economic assistance associated with the 1986  Chornobyl Accident" in which the USA reported its actions since the Chornobyl Disaster.

“Since the horrific 1986 accident at Chornobyl, we have worked with our partners and Ukraine to improve the safety and security of the Chornobyl site and to mitigate the social and economic impact of its permanent closure. To ensure that such accidents will not happen in Ukraine, the United States Government has provided more than $400 million for enhancing nuclear safety of Ukrainian reactors.

This assistance has resulted in significantly improving operational safety of these plants - coupled with an increase in the capacity factor. These projects have ranged from provision of full scope training simulators to technology transfer related to nuclear fuel. In addition, we have implemented numerous nonproliferation programs that have enhanced security of Ukraine's nuclear infrastructure,” states the document.

“Under the direction and coordination of the U.S. Department of State, the United States has been actively engaged in implementing numerous nuclear safety, waste management facilities, and social economic mitigation projects at Chornobyl and in Slavutych. In the area of nuclear safety assistance, working in coordination with other donors, the U.S. provided assistance for safety improvements and construction of the waste management facilities.

The United States is the largest single country donor to the Chornobyl Shelter Fund, the uniquely challenging program which will re-construct the sarcophagus that covers the ruined reactor unit 4 reactor with a pledge of $203 million, out of a total of approximately $1.00 billion pledged to date by the donor countries. United States through the Nuclear Safety Account of the European Bank for Reconstruction and Development, is contributing towards the construction of Interim Spent Fuel Storage and Liquid Radioactive Waste Processing facilities at the Chornobyl industrial site,” says the press release.

In addition, United States provided $32.5 million for construction of the Chornobyl Replacement Heat Plant - the first decommissioning facility to be completed which became operational in June 2001.
