Resolution of the CPSU Central Committee and USSR Council of Ministers "On the construction of the new city of residence of workers of the Chernobyl nuclear power plant".
Near the 4-th power unit, tripped over a crane crashed Mi-8 helicopter, a crew of 4 people died.
The Government Commission adopted the "Conclusion of the reliability and durability of structural coverage, as well as radiation safety of the reactor compartment unit № 4 of the Chernobyl nuclear power plant". Regarding the life of the object in the document reads: "Due to the fact that the cover of the reactor compartment is constructed on the ruined structures and in conditions of high radiation environment and, given the complexity of the installation of structures and control their position, have no possibility to obtain reliable data on their carrier ability. The same document states: "Given the low rate of corrosion in the structural work carried out under protective coatings can be considered as secured their life: from tubes 30-40 years of beams - 30 years. "
For operation of systems and equipment of the Shelter organized the reactor hall of the fourth unit.

December 31, 1987 decision of the Government Commission № 473 approved the certificate of acceptance into operation the third power unit Chernobyl nuclear power plant after the repair works.
To reduce the removal of radioactive aerosols in the environment since the end of 1989 the facility was put into operation a stationary dust suppression system for the application of various chemical compounds in surface of the "collapse", which allowed about 10 times to reduce the "slack" removal of activity from of the Shelter .
The Supreme Council of the Ukrainian SSR and the Council of Ministers of the Ukrainian SSR, to determine the time decommissioning of reactors of the Chernobyl nuclear power plant in 1995. On May 17 The Council of Ministers issued a decree on the development of the program of decommissioning of reactors. On August 2 of the same year the Supreme Council of the Ukrainian SSR declared a moratorium on the construction of new nuclear power plants and to increase the capacity of existing for a period of five years.
In the result of a strong fire in the engine room is stopped the 2 nd unit, also damaged the roof of machine room. The fire served as the basis for the decision of the Supreme Council of Ukraine on an immediate shutdown and decommissioning of the second power unit of the Chernobyl nuclear power plant, as well as to stop the first and third units in 1993.
The moratorium of 1990 on the construction of new nuclear power plants was prematurely removed, and the proposal of the Cabinet of Ministers decided to continue operating the Chernobyl nuclear power plant for a period determined by its condition.
