Abstract

Abstract

The CRAC program was adopted to simulate the control rod drop process in the Chinese advanced fuel assembly under different flow rates. The comparison of the calculation results with the test results showed good agreement. The total rod drop time decreases with the decreasing of the flow rate; the calculation values for the largest and smallest drop time are very close to the test values; and the nominal calculation curve is close to the experiment curve.
