Summary:In order to reduce the quantity of chemical impurities in the primary coolant helium and to remove the gaseous radionuclide fission products, a helium purification system mainly composed of a copper oxide bed, a molecular sieve adsorber and a low temperature adsorber is designed for the HTR-10. One actual purification train is designed for a helium flow rate of 10.5 kg h −1, corresponding with a 5% gas change of the helium inventory in primary circuit. It is anticipated that more than 2000 h continuous purification operation will be reached between regeneration.
