Effect of helium purification system intake pipe on pressure drop of HTGR steam generator

BATAN was proposing to design an experimental power reactor (RDE) that designed based on the technology of High Temperature Gas Cooled Reactor. A carbon dust was found as particle impurities in a helium gas which use as a primary cooling system of the reactor. The carbon dust had a substantial effect on the safety operation of the RDE, thus a helium purification system (HPS) was needed to purify the helium to ensure the performance and safety of the reactor. The intake pipe of the HPS was proposed to be located at the bottom of the steam generator. In this paper, the effect of the helium purification system intake pipe of the experimental power reactor on the pressure drop of steam generator was evaluated with computational fluid dynamics method. The pressure drops in the steam generator with and without HPS intake pipe was compared. Also, a boundary condition of targeted mass flowrate was applied to check the pressure drop needed for the targeted mass flowrate. The pressure drop required for the HPS intake pipe to get 5% of the cooling gas mass flow rate is 7.73 kPa.BATAN was proposing to design an experimental power reactor (RDE) that designed based on the technology of High Temperature Gas Cooled Reactor.
