DESIGN OF HELICAL TYPE STEAM GENERATOR FOR EXPERIMENTAL POWER REACTOR

Reaktor Daya Eksperimental (RDE) is a high-temperature gas-cooled reactor (HTGR) for electricity generation, heat and hydrogen production by Batan. Empirical numerical calculations are needed to strengthen the existing design. The method computational fluid dynamic (CFD) analyzes temperature distribution pressure drop along pipe. Batan RDE steam generator design has seven-layer helical pipe model, while this research uses one-layer helix In empirical calculations, transfer region three sections; single-phase liquid, two-phase, vapor transfer. apply assumption of constant flux working properties. results empiric data showed that height was 3.98 m, shorter than design, which 4.97 m. This considerable difference due did not cover safety factor. show in single-phase, calculation were acceptable since different values below 10%. Meanwhile, case two-phase satisfactory needs further obtain optimal results.
