Supercritical CO2 Brayton cycle is a good choice of thermal-to-electric energy conversion system, which owns a high cycle efciency
and a compact cycle confguration. It can be used in many power-generation applications, such as nuclear power, concentrated
solar thermal, fossil fuel boilers, and shipboard propulsion system. Transient analysis code for Supercritical CO2 Brayton cycle is
a necessity in the areas of transient analyses, control strategy study, and accident analyses. In this paper, a transient analysis code
SCTRAN/CO2 is developed for Supercritical CO2 Brayton Loop based on a homogenous model. Heat conduction model, point
neutron power model (which is developed for nuclear power application), turbomachinery model for gas turbine, compressor
and shaf model, and PCHE type recuperator model are all included in this transient analysis code. Te initial verifcations were
performed for components and constitutive models like heat transfer model, friction model, and compressor model. Te verifcation
of integrated system transient was also conducted through making comparison with experiment data of SCO2EP of KAIST. Te
comparison results show that SCTRAN/CO2 owns the ability to simulate transient process for S-CO2 Brayton cycle. SCTRAN/CO2
will become an important tool for further study of Supercritical CO2 Bryton cycle-based nuclear reactor concepts. |
