Radiation Protection and Health Physics Implications Associated with SMRs for Potential Applications in Turkey

Abstract

The purpose of this project is to develop and demonstrate the models to assess radiation dose rates to personnel within a reactor facility (or in a public area) using the MCNP Monte Carlo code. In this project, the performance of proposed Small Modular Reactors (SMRs) facilities is evaluated on the basis of radiation protection and applicable regulatory limits. A health physics and radiation protection analysis of the small modular reactors is carried out. The scope of this project is to construct an assessment of the radiation risks associated with an SMR. To accomplish this, a conservative dose rate calculation is done and compared with the annual limit intake as per regulations. In addition, geographical and safety requirements are considered for this design. First, a review is made of the regulations and amount of radiation that can be released to the public. The basis for this review is the regulations for the protection of radiation from the U.S. Nuclear Reactor Commission. The evaluation of shielding from the ionizing radiation produced in the core of the nuclear reactor is made. The Monte Carlo N Particle (MCNP) simulation software which uses a stochastic algorithmic approach, is used to test the effectiveness of the design model and learn the dose rates in the area of interest. The objective is to evaluate if this design will be appropriate for use applications in Turkey. Turkey only has one very small research reactor and three power plants under construction. The new plants are located in close proximity to the sea and in comparatively remote areas with low population density.
