Application of Source-Jerk Method on Venus 1# Sub-critical Assembly

In the paper, the Venus 1# sub-critical assembly, configuration of reactor core, the external neutron source system and the neutronics research experiment system about accelerator driven sub-critical system (ADS) were introduced. The sub-criticality of reactor was studied using Source-Jerk method at different loadings. The results of measurement were compared with calculated results, and they are in agreement well.
