NUCLEAR REACTOR - NUCLEAR POWER PLANT

Neutron physics and Nuclear reactor:

-          Interaction of neutron with matter

-          Neutron scattering

-          Neutron Transport Theory

-          Neutron Diffusion Theory

-          Nuclear Reactor Dynamics

-          Computation of distribution of neutron flux and reactor power

Furthermore, we also study on reactor thermal-hydraulic by using CFD (Computational Fluid Dynamics) method to investigate hydrodynamic and heat transfer phenomena in nuclear reactors.

Nuclear Power Plant

In this field, several types of accidents of a nuclear power plant (NPP) are assumed. Using simulation software, physical parameters in nuclear reactor, in turbine building and outside are investigated. The interested parameters are reactivity, neutron flux, fuel temperature, radioactive isotopes, thermal power output, steam temperature, pressure, flow, boron, water level, etc. This study is purposed to teaching and training for ‘s purpose is to teach and train students and also for research. We have several simulation toolkits including PCTRAN, BWR, WWER-1000, CANDU, etc. This package is supported by International Atomic Energy Agency (IAEA).
