An explosion on fourth power unit of Chernobyl’skoy AES in night on April, 26, 1986 became a scale technogenic catastrophe in history of humanity. It was muddy a radiation territory by an area 160 thousand square kilometres. North part of Ukraine, west of Russia and Byelorussia, suffered. After 14 years after a failure, on December, 15, 2000, the station was shut-down. Now on CHAES build a safe object ecologically "Shelter". The special cover will be erected above erected after
failures 1986 years by a sarcophagus. The lump sum of financing of works will make near $1 milliard.The Ukrainian leader approved accepted the proper decree by parliament of country in September, 2008 program on transformation of object "Shelter" in the ecologically safe system.
To 2013 it is assumed finally to close the Chernobyl’skuyu nuclear power plant, create the system of handling radio-active wastes, to complete building of new depository of exhaust nuclear fuel.A law determines that a program purpose is
realization of public policy in preparation to the removal and removal from exploitation of CHAES and transformation of object "Shelter" in the ecologically safe system, providing of defence of personnel, population and environment from influence of ionizing irradiation.To
the final closing and preservation of reactors is 2022 years planned. On the stage it is to 2045 year planned to conduct work on self-control of the reactor settings during a period which the natural decline of radio-active radiation must happen during. To 2065
years, it is planned to conduct dismantling of the reactor settings. A law goes into effect from January, 1, 2010.Building of object "Shelter" set on a summer. All design works must be completed by that time. An object will be a structure
in form arch in a 105 m high, long a 150 m and breadthways a 260 m After erection he will close by itself the fourth block of CHAES, above which a sarcophagus was built in 1986. All works will be conducted under careful international control. Sootve
shelters were signed by Ukraine with the French business concern Novarka and by the American business concern Holtewith International in 2007.On the leadthrough of works required near $1 milliards from which $940 millions will be abstracted from the state budget. Rest of sum will be made by off-budget facilities,
and also facilities of international technical help.
