| Summary: | A neutronic evaluation of the Texas A&M University Nuclear codes, and the results compared with actual experimental Company (GA) low enrichment uranium (LEU 30-20 fuel was control rod worths were calculated using the core model and core configurations. core materials and DIF3D was used to calculate the effective DIF3D diffusion code were utilized. These codes were evaluate the proposed LEU 30-20 core, the current FLIP core excess reactivity, shutdown margin and thermal neutron flux. excess reactivity, shutdown margin, critical rod height and fuel and an optimum core configuration obtained which In addition to modeling the LEU 30-20 core, a control rod In order to benchmark these codes and the core model used to model was developed to generate effective macroscopic cross- multiplication factor and thermal neutron flux for various performed to determine the feasibility of this type of fuel. previous work in this area performed at ANL. The results of provided by Argonne National Laboratory (ANL). WIMSD4m was results for the FLIP core. Once the core model and codes satisfied certain design criteria, including values for Science Center Reactor (TAMU NSCR) using the General Atomic sections for the control rod materials in the core, based on TAMU NSCR to GA LEU 30-20 fuel. this analysis indicate the feasibility of converting the To perform this evaluation, the WIMSD4m transport code and used to calculate macroscopic cross-sections for the various was first modeled. Various neutronic parameters, such as were validated, the core model was modified using LEU 30-20 |
