STUDY ON MCNP6 MODEL IN THE CALCULATION OF KINETIC PARAMETERS FOR PEBBLE BED REACTOR
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
When conducting a nuclear reactor transient analysis, the most important parameter, called the kinetic parameter, is required. The calculation of kinetic parameters can be conducted using several methods. The deterministic ...
Water-air ejector with conical-cylindrical mixing chamber
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
In the paper, the hydrodynamics of the liquid-gas mixture in the mixing chamber of the ejectors at different spatial positions was analyzed and the comparative study of such ejectors was carried out. It was found that a ...
Determination of bond model for 7-wire strands in pretensioned concrete beam
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
A correct choice of a bond model for prestressing tendons is crucial for the right modelling of a structural behaviour of a pretensioned concrete structure. The aim of this paper is the determination of an optimal bond ...
Application of additional insulation to ETICS on surfaces with biocorrosion
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The paper presents partial outputs from an experiment that demonstrated the impact of applying an additional insulation on an existing contact insulation system with a green-algae surface. The aim was mainly to detect the ...
Comparision of the walk techniques for fitness state space analysis in vehicle routing problem
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The Vehicle Routing Problem (VRP) is a highly researched discrete optimization task. The first article dealing with this problem was published by Dantzig and Ramster in 1959 under the name Truck Dispatching Problem. Since ...
