AbstractAbstract
[en] The momentum distribution of residual fragments from knockout reactions provides information on the wave function of incident nuclei. This is important data to study nuclear structure. This report presents details of the experimental set-up and momentum distribution analysis results of 49Cl from SEASTAR (“Shell Evolution and Systematic Search for 2+1 Energies”) experiments, performed at RIKEN, Japan. The experiment used SAMURAI spectrometer, which is characterized by a large angular- and momentum- acceptance, multi-particle detection in coincidence. 49Cl isotope was a product of knockout reactions on a hydrogen target.

AbstractAbstract
[en] With the advent of the Spiral-2 linear accelerator and the associated S3 spectrometer at the Ganil laboratory in France, new realms of intermediate-mass Ν=Ζ and very heavy nuclei will soon become available for research in nuclear structure. After their production and selection in the spectrometer, the ions of interest will be stopped in a buffer gas, neutralised, resonantly re-ionised, cooled and bunched. This will bring us in an adequate position to perform laser spectroscopy, mass measurements and decay spectroscopy of their ground and isomeric states. In this contribution we report on the ongoing commissioning of the detector set-up. (author)

AbstractAbstract
[en] Grid spacers installed in subchannels of fuel assemblies for nuclear reactors can promote heat transfer. However, the fluid velocity and bubble behavior are greatly affected as the cross-sectional area of the flow passage changes. Therefore, the void fraction distribution behind the obstacle that simulates the grid spacer shape simply was measured by using a wire mesh sensor (WMS) system. Moreover, a two-phase flow analysis was performed to investigate the effect of the obstacle on the bubble behavior in a vertical duct.(author)

AbstractAbstract
[en] Since 1996, gaining the approval of Ministry of Science and Technology, Vietnam Conference on Nuclear Science and Technology (VINANST) has been successfully co-organized by Vietnam Atomic Energy Institute (VINATOM) and Vietnam Atomic Energy Society (VAES). As a biennial event, the conference aims to bring together Vietnamese scientists as well as foreign specialists for the exchange of information on the latest research findings and applications in the field of nuclear science and technology, and hence, to foster research and business partnerships among the Institutes, universities and the industry. In addition, VINANST is considered to provide an ideal opportunity for young researchers to approach great sources of specialized knowledge and a range of competencies and skills in their particular disciplines. Following the success of VINANST-12, the conference VINANST-13 has taken place in Halong Bay, a World Heritage site in Vietnam on 7-9 August 2019 in close collaboration between VINATOM and Quang Ninh Department of Science and Technology. As usual, the event held attention for domestic and international experts, scientists, senior managers, researchers, especially representatives from IAEA and its Member States with developed nuclear science and technology.

AbstractAbstract
[en] This paper presents the calculated results of the thermal neutron inelastic scattering cross sections of Bismuth and Sapphire crystals. In these calculations, the effects of thermal neutron scattering on crystal’s phonon vibration and lattice parameters were taken into account by using the NJOY code. These calculated results were updated into the related ACE format data file for MCNP simulation of thermal neutron beams filtered at the Dalat research reactor. (author)

AbstractAbstract
[en] SERPENT, a continuous-energy Monte Carlo Reactor Physics burnup calculation code, was used to create a reactor core that approximates available information on the KLT- 40S reactor. Fission product inventory and decay heat values were extracted from the results and fed into ASTEC (Accident Source Term Evaluation Code), alongside other required physical parameters. A vessel break was simulated to obtain the accident progression and amount of volatile fission products released. These values were then fed into ARGOS, which is an atmospheric dispersion code based on the RIMPUFF (Riso Mesoscale PUFF) model, as the accident source term. The regional radiological impact of the accident was investigated for a hypothetical location and date of the accident, based on real weather data.(author)

AbstractAbstract
[en] In order to investigate on hydrodynamic phenomena in two-phase flow conditions in nuclear safety analysis, a series of two-phase flow experiments were conducted using a single flow channel in which air and water were simultaneously injected into the test section. The experiments under atmospheric pressure condition were carried out with the water velocity and the air velocity covering the ranges from 0.2 to 1.5 m/s and 0.05 to 0.2 m/s respectively. The technique of two-sensor conductivity probe was used for the measurement of bubble parameters The experimental results presented in this study are the local time-averaged void fraction, bubble velocities at three axial positions L/D = 10, 50 and 70.(author)

AbstractAbstract
[en] The applications of Radiation technology recently play an important role in the diagnosis and treatment in Health-care, especially the treatment of oncology. With the advancement of science and technology, the advent of diagnostic and therapeutic devices using the advanced radiation technologies have brought great benefits both in terms of scientific significance, as well as economy. This paper will present an approach on mapping of applications of radiation technology in the fields of nuclear medicine and radiotherapy at Vietnam. The mapping is important in assessing the actual situation, proposing the development plans and perspectives for atomic energy applications in Health-care. The paper will evaluate and analyze the current state of developing nuclear medicine and radiotherapy based on the numbers of equipment and doctors/technicians of the fields via implementing statistics, which will be compared with the Strategy for Utilizations of Atomic Energy for Peace up to the Year 2020 and some other countries. Based on the research results, the paper will discuss and evaluate perspectives and goals in the coming period of developing nuclear medicine and radiotherapy capacity at Vietnam, including the number of equipment and professors, infrastructure.
