Results of Operation and Utilization of the Dalat Nuclear Research Reactor
Tập 4 Số 1 - 2014
The Dalat Nuclear Research Reactor (DNRR) with the nominal power of 500 kW was reconstructed and upgraded from the USA 250-kW TRIGA Mark-II reactor built in early 1960s. The renovated reactor was put into operation on 20th March 1984. It was designed for the purposes of radioisotope production (RI), neutron activation analysis (NAA), basic and applied researches, and nuclear education and training......

Status on development and verification of reactivity initiated accident analysis code for PWR (NODAL3)
Tập 6 Số 1 - 2016
A coupled neutronics thermal-hydraulics code NODAL3 has been developed based on the nodal few-group neutron diffusion theory in 3-dimensional Cartesian geometry for a typical pressurized water reactor (PWR) static and transient analyses, especially for reactivity initiated accidents (RIA).The spatial variables are treated by using a polynomial nodal method (PNM) while for the neutron dynamic solve......

Thermodynamic Hadron-Quark Phase Transition of Chiral Nuclear Matter at High Temperature
Tập 7 Số 1 - Trang 1-9 - 2017
Based on the extended Nambu-Jona–Lasinio (NJL) model with the scalar-vector eightpoint interaction [15], we consider what ultimately happens to exact chiral nuclear matter as it is heated. In the realm of very high temperature the fundamental degrees of freedom of the strong interaction, quarks and gluons, come into play and a transition from nuclear matter consisting of confined baryons and meson......

Design Analyses for Full Core Conversion of The Dalat Nuclear Research Reactor
Tập 4 Số 1 - 2014
The paper presents calculated results of neutronics, steady state thermal hydraulics and transient/accidents analyses for full core conversion from High Enriched Uranium (HEU) to Low Enriched Uranium (LEU) of the Dalat Nuclear Research Reactor (DNRR). In this work, the characteristics of working core using 92 LEU fuel assemblies and 12 beryllium rods were investigated by using many computer codes ......

Progress of Filtered Neutron Beams Development and Applications at the Horizontal Channels No.2 and No.4 of Dalat Nuclear Research Reactor
Tập 4 Số 1 - 2014
The neutron filter technique has been applied to create mono-energetic neutron beams with high intensity, at the horizontal channels No.2 and No.4 of the Dalat nuclear research reactor. The mono-energetic neutron beams that have been developed for researches and applications are thermal (0.025eV), 24keV, 54keV, 59keV, 133keV and 148keV. The relative intensities of main peak in filtered neutron ene......

Discrimination of cosmic-ray in scintillation region and light-guide for plastic scintillation detectors using 5GSPS readout system
Tập 5 Số 3 - Trang 32-37 - 2015
At sea level, the measurement of energy spectrum for cosmic-ray flux determination using two-coincidence plastic scintillation detectors with “traditional” electronic-readout system may include not only cosmic-ray in scintillator region but also light-guide region. In this work, we carry out a measurement of cosmic-ray using two-coincidence plastic scintillation detectors with size of each 80cm×40......
