Analysis of Computer Code and Method Used in Thermal-Hydraulic Safety Justification of VVER Reactor Plants

This article presents the analysis of the calculation procedure and computer code KLAST used in calculations of the control rod dynamic characteristics during safety justification of water-cooled water-moderated power reactor plants. The code allows accounting for pressure differentials as a function of time occurred under the design conditions on the reactor core and on the drive extension shaft as well change of coolant density in the core.

Electromechanical servo system with anisotropic regulator

A method of multiobjective synthesis for nonlinear multi-mass electromechanical servo systems with uncertain plant parameters based on feed-forward robust stochastic anisotropic control to improve the accuracy of such systems is developed. The method is based on the choice of the robust control target vector  by solving the corresponding problem of multiobjective nonlinear programming in which the components of the target function vectors are direct quality indicators that are specified to the system in various modes of its operation.

Experimental Investigation of the Dynamic Processes of a Static Thyristor Compensator for a Mine Load Power Supply System

In order to improve quality of electrical energy in a 35 kV power supply network of a mining load, which feeds from busbars of district substation 330/220/110/35 kV «Novovolynska» of the Western regional electrical system, the static thyristor compensator of reactive power (STC) has been implemented. Conjoint operation of the STC and on-load voltage regulation device of a transformer of the substation allows resolving a task of comprehensive control of the whole power supply system (PSS) of the mining load.

About systematization signs undue advantage, as the subject of giving the criminal code of Ukraine

A systematic analysis of legislative definition of criminal law concept of illegal benefit is conducted in the article. Attention applies on the inconsistence of exposition of separate positions of this legislative definition in notes to the corresponding articles of criminal law norms. Systematization of signs of illegal benefit offers on maintenance, and also by the level of generalization. Conclusions are reasonable about importance of approach of the systems to interpretation of concept of illegal benefit as article of subornation after the criminal code of Ukraine.
