RISNeutron 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 ...
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 ...
Testing Oxygen Nuclear Data Libraries in Research Center Rez
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
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 ...
Measurement of Selected Differential Cross Sections in 235U Spectrum
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the measurement of 55Mn(n,2n) and 127I(n,2n) reaction rates in a well-defined reactor field in a special core of LR-0 reactor. The reaction rates were derived using gamma-spectrometry by measuring gamma ...
Validation of the Fast Neutron Field in the Radial Channel of the VR-1 Reactor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work aims to characterize the neutron spectrum in the beam going out of the university research reactor (VR-1) using tubular-type of the nuclear fuel, version 4M (IRT-4M) fuel. Thanks to its variability, the core is ...
The Application of Silicon-Filtered Beam in the Validation of Iron Cross Sections by Deep Penetration Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper summarizes the issue of the validation of the silicon-filtered neutron beam transport in the deep neutron transport penetration experiment in iron. Iron is an essential structural material important for nuclear ...
