[en] The forecast is based on the value of gross load at a winter peak time of a working day. It is expected that new 440 and 1000 MW nuclear power plants will be introduced by the year 2010. Power balance data for the individual areas in Czechoslovakia, and transmissions from abroad are listed. Briefly described is the condition of the transmission grid and its projected reconstruction by the year 2010. The balance of the Czechoslovak electric power grid will show liabilities between 1995 and 2000 (imports of 175 MW while it will show assets between 2005 and 2010 (exports of 275 MW).

[en] The purpose of the paper is to determine the range of consumers, for whom it is advisable to be supplied with electric power from low power NPPs. Evaluations of the total electric power and heat demand were made for settlements with population of 20 and 50 thousands. The analysis of obtained results showed, that single-unit thermal power of low-power reactor should be limited by 500 MW. Electric power of the unit during operation under heat supply conditions will be equal to 100-130 MW and under condensation conditions - 150-170 MW. Thus, the upper power limit for independent four-unit low-power NPP (with one reserve power unit) is established on the level of 2000 MW

[en] Information concerning the main trends in the development and fields of applying of small-power (600 MW(el.)) reactors is offered, data on economic indices of reactors of this type and the place they occupy at the World power market, are presented

[en] In the years 1992-1995, the target project is to be completed of a nuclear power plant of a new generation with WWER 1000 type units. The operation is briefly described of the project management system that assists in design control and organization, as are the drawbacks in the application of the project in the Czechoslovak situation. A feasibility study has been prepared of an automated integrated information system, which also reflects the important aspects of the project management system. (M.D.). 2 refs

[en] An opportunity to create the space power production on the basis of solar, nuclear and fusion energies is analyzed. The priority of solar power production as the most accessible and feasible in comparison with others is emphasized. However, later on, it probably will play an auxiliary role. The possibilities of fusion power production, as a basic one in future, are also considered. It is necessary to create reactors using the fueling cycle with helium-3 (instead of tritium and deuterium, later on). The reaction products--charged particles, mainly--allow one to organize the system of direct fusion energy conversion into electricity. The produced energy is expected not to be transmitted to Earth, but an industry in space is expected to be produced on its basis. The industrial (power and science-consuming) objects located on a whole number of space apparatus will form a single complex with its own basic power plant. The power transmission within the complex will be realized with high power density fluxes of microwave radiation to short distances with their receivers at the objects. The necessary correction of the apparatus positions in the complex will be done with ion and plasma thrusters. The materials present on the Moon, asteroids and on other planets can serve as raw materials for industrial objects. Such an approach will help to improve the ecological state on Earth, to eliminate the necessity in the fast energy consumption growth and to reduce the hazard of global thermal crisis

[en] This paper describes a 40 kW_e STAR-C thermionic reactor system designed in response to evolving Air Force space power requirements. The resulting nuclear power system is compact and has as overall system efficiency of 11.9%. The entire power conversion subsystem can be pre-launch tested at its operating conditions, independent of the nuclear heat source. System mass, which includes the reactor power subsystem and shield, the power processing and control (PP and C) subsystem and the separation boom has been optimized to 3100 kg. The STAR-C system has been designed to deliver 40.6 kW_e at 95% reliability for 10 years. The system is survivable against SUPER level threats and has no possibility of single point failure

[en] Paper presents the results of the efforts to calculate the characteristics, the layout and the engineering design of the open cycle space power propulsion on the basis of the high-temperature nuclear reactor for a nuclear rocket engine and the Faraday 20 MW capacity MHD-generator. The IVG-1 heterogeneous channel-vessel reactor ensuring in the course of the experiments hydrogen heating up to 3100 K, up to 5 MPa pressure at the reactor core outlet, up to 5 kg/s flowsheet, up to 220 MW thermal power served as a reactor is considered. One determined the MHD-generator basic parameters, namely: the portion of Cs dope was equal to 20%, the outlet stagnation pressure - 2 MPa, the electric conductivity - ≅30 S/m, the Mach number - ≅0.7, the magnetic field induction - 6 T, the capacity - 20 MW, the specific power removal - ∼4 MJ/kg. Paper describes the design of the MHD-facility with the working fluid momentless discharge and its basic characteristics

[en] The Federal Government requires in the safety criteria the proof that it is possible to shut down nuclear power stations. The authors report on an investigation made by the VDEW (Association of German Power Stations) in which the electricity supply undertakings give the results of their considerations and demonstrate that at the end of their operating life nuclear power stations can be shut down with reasonable technical outlay.
