Analysis of cogeneration energy conversion system design in IPWR reactor

The acceleration of national development, especially in the industrial sector, requires an adequate national energy supply. There are various types of energy sources such as conventional energy sources, new and renewable energy sources including nuclear energy. The problem is how to utilize these energy sources into energy that is ready to be utilized. As a research and development institution in the nuclear field, BRIN has taken the initiative to contribute to the development of technology for providing electricity and other thermal energy, particularly reactor technology as a power plant and a provider of thermal energy. This research aims to analyze IPWR type SMR reactor design as a cogeneration energy conversion system. The IPWR reactor coolant as a cogeneration energy conversion system is arranged in an indirect cycle configuration or Rankine cycle. The primary cooling system and the secondary cooling system are mediated by a heat exchanger which also functions as a steam generator. The analysis was carried out by simulation using ChemCAD computer software to study the temperature characteristics and performance parameters of the IPWR as a reactor cogeneration energy conversion system. The simulation results show that the temperature of saturated steam coming out of the steam generating unit is around 505.17 K. Saturated steam is obtained in the reactor power range between 40 MWth to 100 MWth. Energy utilization factor (EUF) calculation shows that the IPWR cogeneration configuration can increase the energy utilization factor value up to 91.20 %. (author)
