The contribution describes the new measuring and protection system of the VR-1 training reactor. The measuring and protection system upgrade is an integral part of the reactor I&C upgrade. The new measuring and protection system of the VR-1 reactor consists of the operational power measuring and the independent power protection systems. Both systems measure the reactor power and power rate, ini...

In nuclear reactor design, the most fundamental task is to follow the neutron distribution as a function of space, direction, energy and time, in order to maintain and control the nuclear fission chain reaction. The fundamental equation governing the average behaviour of neutrons is given by the linear form of Boltzmann transport equation, which is an integro-differential equation. The core sim...

The utilization of clean energy is a matter of primary importance for sustainable development as well as a vital approach for solving worldwide energy-related issues. If the low utilization rate of nuclear fuel, nuclear proliferation, and insufficient nuclear safety can be solved, nuclear fission energy could be used as a sustainable and low-carbon clean energy form for thousands of years, prov...

the application of neural networks to model a laboratory scale inverse fluidized bed reactor has been studied. a radial basis function neural network has been successfully employed for the modeling of the inverse fluidized bed reactor. in the proposed model, the trained neural network represents the kinetics of biological decomposition of organic matters in the reactor. the neural network has b...

The Molten Salt Fast Reactor (MSFR) is a nuclear reactor concept under development in the framework of H2020-Euratom project SAMOSAFER. Given its peculiar characteristics as circulating-fuel reactor, new simulation tools need to be developed and tested for study. In this work, multiphysics solver previously OpenFOAM extended with functionalities analysis design. main focus modelling behavior Ga...

Actin polymerization is important for vesicle fission during clathrin-mediated endocytosis (CME), and it has been proposed that actin polymerization may promote vesicle fission during CME by providing direct mechanical forces. However, there is no direct evidence in support of this hypothesis. In the present study, the role of actin polymerization in vesicle fission was tested by analyzing the ...

In this paper we present a bond graph model of a Continuous Stirred Tank Reactor which represents the reaction kinetics as well as the heat and mass transport phenomena in the reactor. The consequences of reticulation of the phenomena and of the systematic use of the power conjugated variables on the formulation of the thermodynamic properties, the reaction kinetics and the energy and mass tran...

The naval industry has integrated the generation of energy through nuclear processes, due to large amount that is produced in these for example, ship NS OTTO HAHN, which used a propulsion plant with generated by reactor pressurized water (PWR), operated under fission process. Also, other examples are military ships and icebreakers. In order know contribution this type plants, work carries out m...
