WORKS OF THE INSTITUTE OF ENGINEERING THERMOPHYSICS ON THE SOLUTION TO THE PROBLEMS OF THE DESTROYED REACTOR AND NEW CONFINEMENT. (TO THE 30TH ANNIVERSARY OF THE CHERNOBYL ACCIDENT)
An activities review of employees of IETP of NAS of Ukraine on the mitigation of the implications of the accident at Unit 4 of the Chernobyl nuclear power plant, April 26, 1986 is shown. To identify and study nuclear fuel and fuel-containing material accumulation places heat flow and temperature transducers have been developed and manufactured. The work on the forecasting of probable warming up of the destroyed reactor due to being filled with various materials (concrete, expanded clay and scraps of steel pipes) was performed. Computer models were developed and the results of the analysis and forecasting of heat and gas dynamic processes are presented for the New Safe Confinement and "Object Shelter" of the Chernobyl nuclear power plant in order to verify the fitting to defined criteria of engineering systems performance.
