The article is devoted to the solution of the task of choosing the working fluid for the heat-power circuit of power plants onrnnon-aqueous working substances. The authors formulated number of technical proposals for the introduction of fluorocarbonrnworking substances in the heat and power circuit of fast-neutron nuclear facilities with a liquid metal heat transfer phenomena. Inrnthe article, based on the analysis of the material balances of the presence of ozone-hazardous or greenhouse substances in the Earth\'s atmosphere and taking into account industrial and natural emissions over certain periods of time, shows the groundlessness (and,consequently, the invalid pattern) of the provisions on which international agreements on prohibition are based and the restriction of the use of a number of substances. Based on processing of mass balances according to IPCC-94 and IPCC-2013 the conclusions are made about the overestimate in IPCC-94 lifetime assessment for the most stable fluorocarbon CF4, which gives grounds for removing restrictions on the use of fluorocarbons on the basis of the greenhouse hazard and creates the conditions for studying the technological properties of fluorocarbons. Study of the thermal stability of fluorocarbon compounds (C3F8, C4F10) under constant andrncyclic heating in the presence of structural materials containing catalysts has been done. Under these conditions, the temperature of the beginning of the thermal decomposition of octafluoropropane is 630ºC, decafluorobutane is 600ºC. We also studied the impactrnof radiation on fluorocarbon working fluids (under α- and β-radiation). As calculations have shown, when using fluorocarbons, the required level of thermodynamic efficiency is reached at a pressure of 6 to 10 MPa (for water up to 24 MPa), which positively affectsrnthe safety of the reactor plant without reducing the efficiency. In the indicated range of pressures and temperatures up to 550°C therernis an optimum pressure value at which the cycle efficiency is maximal.

Calculation and further analysis of density matrix (DM) for projectile which collides with a solid film reveals some new representations which is hard to be anticipated without the calculation namely: The coherence properties in the projectile’s wave field are describing through the special function of coherence. The collision with the solid leads to a significant decrease in the total\r\ncoherence length of the projectile’s wave field. The coherence length can become much smaller than the initial size of a wave packet of a particle passing through the film. During the collision with solid the number of different spatial areas where the mutual coherence in the projectile’s wave field is supported, can be multiplied. Every part of projectile’s wave field can be individualizing as the separate\r\nparticle having own property in its inner quantum state. The procedure which has a responsibility for such a transformation can be characterized as a spontaneous breaking of symmetry. The process described in the point 3 can be considered as a special form\r\nof breaking in quantum mechanics. Knowing the wave packet evolution during the passage through the solid film allows one to\r\nexplain experimental results on the pore formation during the passage of high charged atomic ions through the thin carbon nanomembranes.\r\nThe parts of the wave field considered above can be stabilized in its quantum state after it has been captured in its own\r\npolarization well.
