Abstract
In this research, MCNP code and ORIGEN code are used to calculate the control rod reactivity worth effects by simulating the 3D core model of CMRR reactor. The integral and differential behaviors of reactivity worth effects are measured by rod-drop experiments and digital inverse kinetic method with each other. The calculated and measured results are well accorded. The integral reactivity worth of one safety rod is about 4%k/k. Even in an accident when one safety rod gets stuck, the CMRR shutdown margin is still greater than 10%k/k, and CMRR is totally safe. So the physical design of CMRR is highly reliable and the operation could be safe.
