Vietnam can participate in the design of a new research reactor for the National Nuclear Science and Technology Center
|
|
|
That is the conclusion drawn from the results of an independent national project for the period of 2016-2020 on the research, calculation of neutron characteristics, hydrothermal and safety analysis of nuclear reactors research for the Nuclear Science and Technology Center (DTĐL.CN-50/15). The project is implemented by Associate Professor, Dr. Nguyen Nhi Dien (VINATOM).

During the implementation, he and his colleagues investigated, established and calculated the neutron and hydrothermal designs for the four reactor reactor configurations: 1) Configuration using IRT-4M fuel with rim Beryllium (Be) reflector; 2) The configuration uses VVR-KN fuel with Be reflective rim; 3) The configuration of using MRT fuel with Be reflective rim; and 4) MTR fuel configuration with heavy water reflector (D2O). The proposed configurations have specifications that meet the multi-purpose applications of a contemporary reactor worldwide with the same power level.
The calculated values of neutron flux are well suited for typical applications, including: production of 8 types of radioactive isotopes common in nuclear medicine (Mo-99, I -131, I -125, Y -90, Ho -166, Lu -177, S -35, P- 32 and Sm- 153) and closed radioactive sources for medicine (I-192) and industry (I -192, Se-75, Co - 60) for domestic and export demand, neutron activation analysis, single crystal silicon doping irradiation, material structure study by neutron scattering and diffraction techniques, neutron imaging, and etc. One of the results of the project is the publication of “Conceptual design of a 10 MW multi-purpose research reactor using VVR-KN fuel” which was published in Science and Technology of Nuclear Installations. |
