This study shows the feasibility of using Erbium as a burnable absorber (BA) in the VVER-1000 reactor. Nowadays, Gd2O3 is commonly used BA in the form of additive compounds in the nuclear fuel for light water reactors. This analysis compares standard gadolinium absorber with a...

Nuclear data uncertainty propagation can be analyzed for various applications. Uncertainty of neutron multiplication factor during fuel depletion is the response quantity of interest for burnable absorber research. Three different fuel assembly (FA) designs were analyzed, FA without burnable absorber&...

Pulse-width modulation (PWM) is widely used for control in power electronics. The most of power electronic circuits are controlled by PWM signals of various forms. PWM transform the information in the amplitude of a bounded input signal into the pulse width output signal. The ...

In this paper the experiments with two mutually coupled digital oscillators are described. The digital oscillators with quadrature outputs are used for experiment. On the beginning the amplitude stabilization and way of synchronization of digital oscillator are described. Then the behavior o...

Photovoltaic (PV) system applications in Renewable Energy Sources, Power Grid and Distributed Generation are widely increased due to rapid changes in the technology, crave for alternative clean energy, need to protect environment and also due to favorable regulations, incentives and the poli...

A frequent difficulty occurring in solving electroheat problems is correct setting of the temperature-dependent material characteristics. These are well known in the case of the pure metals, but not so much for alloys, as they depend on their chemical compositions. The paper presents&#x...

Partial discharge (PD) signal analysis is a well-known tool for monitoring the conditions of insulation systems of electrical machines and equipment. Classical analyzes of PD are mostly based on the eval- uation of the phase angle of the test voltage at which partial discharges...
