Monitoring of sensor operation is important for detecting anomalies and reconstructing the correct values of the signals measured. This can be done, for example, with the aid of auto-associative regression models. However, in practical applications difficulties arise because of the need of handling large numbers of signals. To overcome these difficulties, ensembles of reconstruction models can ...

This article examines the current prospects for developing nuclear energy in Ukraine terms of sustainable development. The strategic importance is indicated. advantages context electricity production's external costs over other generation technologies are noted. Today, considered most cost-effective low-carbon source. An analysis reports from Atomic Energy Agency and US Department shows that po...

A novel catalytic reactor with dielectric barrier discharge (DBD) at atmospheric pressure was developed for the abatement of volatile organic compounds (VOCs). The novelty of DBD reactor is the metallic catalyst serving also as the inner electrode. The catalytic electrode was prepared from sintered metal fibers (SMF) in the form of a cylindrical tube. Oxides of Mn and Co were deposited on SMF b...

The Advanced High-Temperature Reactor is a new reactor concept that combines four existing technologies in a new way: (1) coated-particle graphite-matrix nuclear fuels (traditionally used for helium-cooled reactors), (2) Brayton power cycles, (3) passive safety systems and plant designs from liquid-metal-cooled fast reactors, and (4) low-pressure molten-salt coolants with boiling points far abo...

The SOMBRERO inertial fusion reactor conceptual design produces 1000 MWe utilizing near symmetric illumination of targets by KrF laser. The blanket design optimization results in achieving an overall tritium breeding ratio of 1.25 and an overall reactor energy multiplication of 1.08. The first wall is expected to have a 5 full power year (FPY) lifetime. The shield surrounding the reactor chambe...

have sprung to life in these recent years at the welcome sight of a possible nuclear power renaissance, IRIS (International Reactor Innovative and Secure) is the one that has moved most rapidly from an idea to a viable, albeit still at the preliminary design stage, commercial entry. IRIS is a modular pressurized water reactor with an integral configuration (all primary system components—pumps, ...

LIBRA-SP is a 1000 MWe light ion beam power reactor design study. The reactor structure is made of a low activation ferritic steel and uses LiPb as a breeder. The total activities in the blanket and reflector at shutdown are 721 MCi and 924 MCi, respectively. Hands-on maintenance is impossible anywhere inside the reactor chamber. The biological dose rates near the diode are too high at all time...

In this study, hydrogen production performances of groundnut shells in a circulating fluidized bed gasifier is evaluated by employing previously developed and validated model. Basically, we simulate gasification system that connected to water-gas shift reactor, for purification with the temperature 1150 K. We find amount gas produced from increases 49.25 kmol 68.83 (per 1000 kg raw shells) when...

Modeling of dynamic processes in nuclear reactors is carried out, mainly, on the basis of the multigroup diffusion approximation for the neutron flux. The basic model includes a multidimensional set of coupled parabolic equations and ordinary differential equations. Dynamic processes are modeled by a successive change of the reactor states, which are characterized by given coefficients of the e...
