ABSTRACT Waste disposal processes and landfill management are crucial subjects in the field of settlement archaeology. Our study is focused on understanding that connected to formation infills features recycling building materials (daub wood) waste management. These research questions addressed through analysis plant macroremains, charcoals, phytoliths, starch, micromorphology, phosphates magnetic susceptibility. The results show character feature infills, which reflect economy individual...
The Mini Labyrinth experiment is a neutron and gamma shielding currently being developed at the Slovak University of Technology, Bratislava (STU). STU consists NEUTRONSTOP blocks, water tank, PuBe source, graphite prism.

One of the most effective ways gaining user experience and minimizing effects on modelling simulation is benchmarking. Currently (2022) a new experimental workplace, so called 'Mini Labyrinth' being developed at Slovak University Technology in Bratislava (STU). It simple neutron gamma shielding benchmark, inspired by ALARM-CF-AIR-LAB-001 ICSBEP experiment. The latest V2 setup consists PuBe source, several NEUTRONSTOP C5 blocks, H2O filled polylactic acid (PLA) tank, plastic source holder...
Most of the electricity produced in nuclear power plants comes from pressurized water reactors. Currently, main fuel reactors is enriched uranium. The thermal energy by fission uranium 235 using slow (thermal) neutrons. Generation IV are already contemplate obtaining 238 fast neutron. Neutrons interact simultaneously with materials present a reactor. Probability and mode interaction depend on neutron energy. Therefore, paper focuses measurement spectra field distribution reaction rate gas...
This paper compares the results of two experiments with graphite block which has 39 holes drilled into it. In one experiment most were filled NaCl and neutron flux density was measured using Au activation detectors. During second experiment, in prism without any salt. The reaction rates compared analysed.
The Mini Labyrinth experiment is a simple neutron and gamma shielding developed at STU, inspired by the ALARM-CF-AIR-LAB-001 ICSBEP benchmark experiment, originally constructed in former Soviet Union 1982. Compared to original Labyrinth, which was made from concrete blocks had dimension of several meters, STU approximately ten times smaller consists NEUTRONSTOP blocks. purpose this validate computer codes partners involved APVV-DS international project "Experimental simulation studies...

Abstract Waste disposal processes and landfill management are crucial subjects in the field of settlement archaeology. Our study is focused on reconstruction community economy context Late Bronze Age; understanding that led to filling these features; recycling system building materials (daub wood) waste management. These research questions were addressed based plant macroremains, charcoals, phytoliths, starch, micromorphology, phosphates magnetic volume susceptibility. The results showed...
This study is focused on analysis of fundamental physical and neutronic properties typical materials used for spallation target design. A set calculations using TALYS code has been performed results containing neutron yields various have obtained. Additionally, two Monte Carlo codes MCNP PHITS were compared via calculation spectra generated by 660 MeV proton beam interacting with target.
A paper deals with the measurement of effect fast neutrons from Cf-252 neutron source on muon background detection NaI(Tl) scintillation detector. Previous research at TAMU has shown a possibility to measure high-energy cosmic ray particles, or secondarily produced muons, predict natural in search for artificial sources by mobile systems. One problems encountered testing was increased contribution gamma rays small distances between and detector, which affects measurements. primary prompt...
Knowledge of neutron energy spectra is very important because neutrons with various energies have a different material impact or biological tissue impact. This paper presents basic results the flux distribution inside new experimental research stand SVICKA which located at Brno University Technology in Brno, Czech Republic. The experiment also focused on investigation sandwich shielding quality that protects staff against radiation effects. set indium activation detectors was used to...

The experiments were performed with a spallation target QUINTA, which contains 512 kg of natural uranium in five sections. Threshold activation detectors cobalt placed the whole volume target. irradiated secondary neutron field generated by 660 MeV proton beam. first experiment was lead shielding around and second one carried out without shielding. threshold measured analyzed using gamma-ray spectroscopy. experimental results reaction rates from compared experiment.
The influence of the fuel thermal conductivity
The aim of this paper is to introduce experimental assembly B-URAN and the results Monte Carlo simulations neutron fields, which will be generated by using various spallation targets. This was constructed in Joint Institute Nuclear Research Dubna, Russian Federation, order study accelerator driven systems fundamental characteristics. Beam 660 MeV protons should used for that purpose. MCNP model such set-up has been developed at Brno University Technology, Czech Republic. goal get data needed...
Analysis of neutron distribution was carried out for two elongated targets.
