Nuclear Reactor Physics UNIST CORE (COmputational Reactor physics and Experiment laboratory) researches about nuclear reactor physics. Nuclear reactor physics is based on neutron transport theory and neutron reactor physics.  Nuclear reactor physics is based on neutron transport theory and neutron diffusion theory.  This study fields are neutron behavior which are collision with medium, scattering, absorption, nuclear fission, chain reaction, energy distribution prediction and control. It manages knowledge to need reactor core design, analysis and operation, which are criticality, reactivity control, neutron moderation, neutron transport theory, neutron diffusion theory, dynamics, and reactivity feedback. 유니스트 원자로물리연구실은 원자로물리에 대하여 연구하고 있습니다. 원자로물리란 중성자 수송이론 및 확산이론을 기초로 원자로 내에서 중성자의 거동 즉, 매질과 충돌, 산란, 흡수, 핵분열 및 연쇄 반응 등을 연구하고, 중성자의 시공간 및 에너지 분포를 예측 및 제어하는 방법을 연구하는 공학의 한 분야입니다. 임계, 반응도 제어, 중성자 감속, 중성자 확산이론, 중성자 수송이론, 동특성, 반응도 궤환 등 원자로 설계, 해석 및 운전에 필요한 지식을 다룹니다.
