Abstract

The Sustainable Development Goals (SDGs) are aided by nuclear power plants (NPPs), a form of power generator that generates economical, clean, and climate-friendly electricity. To find appropriate parameters for the SRAC-2006 and JENDL-4.0 modules with PIJ module for cell calculation and CITATION module for core calculation. this study is simulated for MSR FUJI-12 as one of the fourth generation of reactor. This study continued to optimize the core reactor to achieve a Conversion Ratio (CR) approaching 1 and a Power Peaking Factor (PPF) approaching 2. Variations in the number of core regions-two and three regions-with different fuel percentages were explored. By variating the composition of fuel and moderator or Moderator to Fuel Ratio (MFR) for each region, it was found that the MSR FUJI-12 with three regions and fuel percentages of 50%-30%-40% achieved a CR of 0.962 and a PPF of 2.579. However, this variation impacted the life cycle of the reactor from its adjustment on fuel and moderator to only 1400 days.This limited lifespan could be addressed with the concept of online refueling, applicable to MSR technology.
