Large Carnivores of the Chernobyl Nuclear Power Plant Exclusion Zone During nine years observations on large carnivores of Exclusion Zone have been carried out. Species composition and the number of large predators in the Exclusion Zone correspond to the regional conditions. The presence of bears and permanent stay of the lynx in the Exclusion Zone was confirmed. Six wolf packs were counted. The use of an anthropogenically transformed areas, the shift of the daily regime of activity and characteristics of the diet are the most specific features of this animal group.

Purpose. To increase the level of medical care for depression patients with autoaggressive manifestations (AM) in victims during a radiation disaster and fighting by developing new diagnostic and treatment programs. Material and methods. The object and methods of the study were 70 liquidators of the accident consequences at the Chernobyl nuclear power plant aged from 54 to 65 years old and 45 combatants of the Anti-terroristic operation (Joint forces operation) aged from 25 to 59 years old – comparison group, depression patients with AM, psychosomatic pathology were examined. For the main group and the comparisons group were used clinical and paraclinical methods, division into groups, according to diagnostic and treatment programs, therapy and follow-up from 2 months to 2 years. Results. The main group observed increasing depressive frequency disorders with AM in liquidators of the accident consequences at the Chernobyl nuclear power plant. The examination revealed asthenic – in 34 (48.6 %) patients, anxiety – in 13 (18.6 %), apathetic – in 8 (11.4 %), hypochondriac – in 7 (10 %), dysphoric – in 5 (7.1 %), obsessive-phobic – in 3 (4.3 %) variants of depression with AM. These particular disorders are characterized asthenic, anxiety and apathetic symptoms, progressive course, personality changes with organic and psychosomatic traits, cognitive deficit (р <0,05). In the comparison group, asthenic was found in 13 (28.3 %) patients, anxious in 11 (23.9 %), hypochondriac in 10 (21.7 %), dysphoric in 6 (13 %), and obsessive-phobic – in 3 (6.5 %) and apathetic variants – in 2 (4.4 %) depression with AM. After the participation in the Anti-terroristic operation (Joint forces operation) fighters exhibit depression with AM in combination with psychosomatic and personality traits, changes in the bioelectrical activity of the brain. These particular disorders are characterized asthenic, anxiety, hypochondriac symptoms, personality and psychosomatic traits (р <0,05). Conclusions. The proposed comprehensive treatment and diagnostic program will increase the level of medical care of the liquidators of the accident consequences at the Chernobyl nuclear power plant, combatants of the Anti-terroristic operation (Joint forces operation) and prevent the occurrence of suicide. Key words: depression, autoaggressive manifestations, diagnostics, treatment, prevention, combatants of the Anti-terroristic operation (Joint forces operation), liquidators of the consequences of the Chernobyl accident.

THE PURPOSE. System efficiency and competitiveness assess of a new scheme for combining a nuclear power plant with a hydrogen complex based on additional heating of feed water and superheating of live steam in front of the high-pressure cylinder of a steam turbine. METHODS. Basic laws of thermodynamics were applied when developing and substantiating a new scheme for combining a nuclear power plants (NPP) with a hydrogen facility; theoretical regularities were applied of heat engineering; basic regularity were applied of fatigue wear of power equipment and assessment of its working resourse; basic regularities were applied for the assessment of operating costs and net present value (NPV). RESULTS. A new scheme is presented of the combination of a nuclear power plant with a hydrogen facility and a description of its operating principle on the example of a two-circuit nuclear power plant with a VVER-1000 reactor and a C-1000-60 / 1500 turbine. The data are presented on an increase in the productivity of steam generators at nuclear power plants with additional heating of feed water in the range of 235-250 ° C from its nominal value of 230 ° C. The temperature was estimated of live steam superheat depending on the temperature of the additional heating of the feed water. The results are presented of the calculation of the generated peak power by the power unit and the efficiency of conversion of the night off-peak power of the NPP into peak power, as well as the efficiency of the power unit of the NPP depending on the temperature of additional heating of the feed water. Main regularities are given for taking into account the fatigue wear of the main equipment of the hydrogen facility, including the rotor of the NPP turbine in the conditions of the stress-cyclic operation. The results are presented of assessing the cost of peak electricity NPP in combination with a hydrogen facility in comparison with a pumped storage power plant (PSPP) both for the current period and for the future until 2035. CONCLUSION. Hydrogen facility efficiency and competitiveness depends significantly on the intensity of the use of the main equipment in the conditions of the intense-cyclic operation. The hydrogen facility will competitiveness noticeably increase in comparison with the PSPP in the future. Efficiency of the NPP power unit and NPV is highest when the feed water is heated to 235 ° C and superheating of live steam in front of the high-pressure cylinder of the C-1000-60/1500 turbine up to 470°C.The hydrogen facility competes with the PSPP with her specific capital investment at the level of 660 USD / kW, provided that the boosting capabilities of the turbine are used with live steam overheating at 300 ° C and additional heating of feed water to 235°C on the current period. The PSPP does not compete with the hydrogen facility both for the current period and in the future with her specific capital investment of $ 1,500 / kW and above.
