Abstract

Abstract

A full size and truncated（used in small modular reactors） CF2 fuel assembly were adopted in the hot rushing test. The experiment was carried out in the condition of high temperature and pressure, where the components of the driving line were simulated as 1:1. The reliability and anti-abrasion of fuel assembly was tested. The dropping performance data were obtained for the two sizes of fuel assembly. Moreover, the method of rushing test was also discussed in this paper. It provided an important experimental basis for the optimization design, safety assessment and application of domestic advanced fuel assembly.
