During the commissioning of the primary helium circulator of the high-temperature gas-cooled reactor (HTGR), it could not complete the performance test of the full speed range, because the resistance of the primary loop was lower than the design condition. Based on the theoretical characteristics of the primary helium circulator and similar principles, a method for calculating the commission parameters of the primary helium circulator under different resistance conditions is developed. Combined with the monomeric test operating points of the primary helium circulator, accurately calculated the operating point parameters of the cold and hot performance tests of the primary helium circulator, and guided the completion of the full speed and full power performance tests of the primary helium circulator in HTGR. By comparing and analyzing the commission and factory test results of the primary helium circulator, the feasibility of this calculation method is verified, and provide correction factors for the conversion of working conditions between air medium and helium medium. Through comparing and analyzing the commission and operation data of the primary helium circulator, it can be seen that the commission conditions provided in this article have sufficient enveloping ability, which can cover all operating conditions of the primary helium circulator during the operation of HTGR. This proves that the variable resistance condition commission method of the primary helium circulator meets the performance verification requirements of HTGR, and it can be used to guide the primary helium circulator commission of subsequent HTGR.
