Abstract

Neutron irradiation device introduced to the hospital zero power and equipment, the use of MCNP code for IHNI zero power device simulation calculations, the center control rod worth, the beryllium reflector efficiency, the radial component of fuel efficiency, aluminum watt efficiency. Calculated and experimental values ​​of mutual authentication, the results are in good agreement. Zero power experiment and equipment of in-hospital neutron irradiator was introduced. IHNI equipment was simulated and calculated with MCNP code. Compared with the zero power experimental, the calculation results of the central control rod value, the top beryllium reflection efficiency, the radial fuel elements efficiency and the aluminous tile efficiency accord well
