RISSpecial Issue: Research Center Řež: Nuclear-Engineering Activities in 2020
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This special issue is dedicated primarily to research performed in the Research Centre Řež Centrum Výzkumu Řež (CVŘ hereafter) during the Research for SUSEN (R4S) project (project solved in CVŘ), which is the follow-up of ...
Study of a Gamma Radiation Impact on Concrete Properties Under Severe Accident Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Concrete is an important structural material used in nuclear power plant (NPP) design. Due to relatively high amount of hydrogen as well as the presence of heavier elements, it also acts as a biological shielding. One of ...
Neutron Field Shaping Using Graphite for Reaction Rate Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Neutron field shaping is the suitable method for validation of cross section in various energy regions. By increasing the share of neutrons of a certain energy interval and decreasing the share of other, a reaction becomes ...
Overview of Validation Experiments Focused on Silicon in LR-0
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Silicon dioxide is a common material in nature and is also often used in the nuclear industry (concrete, radioactive waste repositories in bedrocks), therefore, properly characterizing neutronic properties is very important ...
Methodology of 63Cu(n,2n)62Cu Reaction Rate Measurement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the measurement of the spectrum-averaged cross section (SACS) of 63Cu(n,2n)62Cu reaction in 252Cf spontaneous fission neutron spectrum. The SACS in the 252Cf spectrum was chosen as a validation tool ...

Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Jan’s contribution to nuclear water chemistry, utilization of research reactors, and nuclear fusion research strongly impacted the technology development on both the national and international scientific scenes. Working ...
Investigation of 127I(n,2n)126I and 23Na(n,2n)22Na Reactions Using 252Cf Neutron Source
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: This work deals with 23Na(n,2n)22Na and 127I(n,2n)126I reactions in the 252Cf spontaneous fission neutron source. 252Cf neutron source with approximate emission of 6·× 108 n/s was employed for the irradiation of sodium ...

Abstract: Oxygen belongs to the group of the most important isotopes in the nuclear data field. The aim of this paper is validate various oxygen nuclear data libraries in different scenarios with high content of oxygen. For this ...
Comparison of Neutron-Gamma Separation Qualities of Various Organic Scintillation Materials and Liquid Scintillator LSB-200
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, we compare the pulse-shape discrimination (PSD) properties of newly developed liquid scintillator LSB-200, EJ-299-33A, BC-501A, stilbene, p-terphenyl, and Hidex Aqualight in neutron field generated by the ...
The Use of Polycarbonate as Dosimeter of High Doses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dosimetry of high doses of ionizing radiation is a method widely used not only in the field of basic and applied research but also in various industries. High-dose irradiation is used in the sterilization of foodstuffs and ...
