Shielding Analysis of High Density Polyethylene and Borax for Lead Slowing Down Time Spectrometer System
- 1. Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)
Description
A lead slowing down time spectrometer(LSDTS) system has been designed in order to analyze the contents of the special materials such as U-235, Pu-239, Pu-241. However, the target in LSDTS emits a high intensity of neutron and gamma rays when operating. For example, a typical neutron yield of LSDTS is about 1E+12 neutrons/s. In this study, a shielding evaluation was carried out with a simplified and real size model of the LSDTS system in order to protect neutron. The MCNPX code, a popular Monte Carlo three dimensional code, was used and this study was also performed for the shielding structure, thickness, materials and distance. Additionally, Variance reduction with geometric splitting technique was tried in order to get highly efficient results
