Basic tendencies in development of nuclear power industry at the beginning of 21 century are demonstrated with advanced nuclear reactors of the third-generation. After definition of
generations of industrial nuclear reactors the principal designs of the second-generation reactors now in operation are briefly considered. The present concepts and designs of the third-
generation reactors are considered in details - both of high (above 300MWte) and of low powers. These reactors being an evolutionary development of the proceeding generation satisfy
a number of severe requirements and are much more cost-effective. Their most significant distinction from the second-generation reactors is in elements of passive or inherent safety. In
the case of plant failure to prevent an accident these mechanisms do not require active intervention of in-plant personnel but rely on physical principles of gravity, natural convection and
sufficient heat-resistance of construction elements. Various types of the third-generation reactors are mentioned in the review - they are water-cooled, gas-cooled, liquid metal-cooled
and molten salt reactors with water and graphite moderators and different fuel elements: rod-like, spherical and prismatic. The reactor core can be of modular, integral, vessel- or pool-
type designs etc. Russia is one of the countries leading in nuclear reactor industry. Nuclear power plants of Russian designs operate on the territory of Ukraine. That is why the third-
generation reactors developed and designed in this country are considered in more detail. One of the purposes of the review lies in the attempt to estimate what advances in nuclear
reactor industry can be essential in our country and what are the goals of Ukraine in its future nuclear-power program. The review connects short analysis of the current state of
Ukrainian nuclear power industry and the objectives of its development in the 21st century taking into consideration "The Power Strategy of Ukraine" and the corresponding scenarios of
the development of its nuclear power industry up to 2030.

Experimental results of space-time characteristics of negative corona discharge radiation in air under Trichel pulsed mode, are presented. It was shown, that negative corona discharge
radiation concentrated near cathode and anode areas, and radiation intensity considerably depends on anode shape. Corona discharge radiation under Trichel pulsed mode has pulse
character. At the same time the radiation pulse from the needle cathode area appears with current pulse simultaneously, but the radiation pulse from the anode area is formed with time
delay to the beginning of the current pulse. The time duration between the beginning of the current pulse and the beginning of the radiation pulse, from the anode area, depends on
applied voltage value and the distance between electrodes, however the amplitude relationship of radiation pulses depends on the applied voltage value only.
KEY WORDS: negative corona discharge, Trichel pulse, radiation, drift zone, anode area, perturbation wave, anode shape.

The features of barrier contact forming on high-resistance semiconductor compound CdZnTe p-type for making detectors X- and γ-irradiations were reviewed. Efficiencies of gamma-irradiation registration in a wide power range by CdZnTe crystals of different thickness were estimated. The equivalent circuitry of a MSM structure is offered, allowing to simulate various
types and variants of electrodes. On the basis of Au-CdZnTe-In structure was created detectors for detecting low-energy γ-irradiation, characterized by small leakage current 1,5
nA at a bias voltage 100 V.
KEY WORDS: CdZnTe, detector, γ-irradiation, voltage-current characteristic, contact, metal-semiconductor-metal structure.

The main mechanisms of accumulated particles losses, such as elastic and inelastic scattering by electrons and nuclei of residual gas atoms; intrabeam scattering (Toushcek effect),
quantum life time in the electron storage ring NESTOR (N-100M) what construct in the NSC KIPT for generation of intensive X-Ray beam on the base of Compton scattering are considered. It is shown that the main losses of the accumulated beam in the area of low energies of the beam happen due to elastic particles scattering on nuclei, while in the field of high energies inelastic scattering effects prevail. Dependence of partial and total lifetimes on the energy of an electron beam is built. Vacuum chamber aperture and value of dynamic pressure are defined.
KEY WORDS: lifetime, electron beam, electron storage ring, vacuum chamber, residual gas.
