Simulation Analysis of Neutron Time-space Kinetics for Venus-II Lead Cold Zero Power Reactor Based on IQS/MC program

摘要

Accelerator driven sub-critical system is driven by an external neutron source which are generated by spallation reaction and maintains the stable operation of sub-critical core,while the external neutron source increases the complexity of reactor neutron kinetics processes.Numerical simulation of neutron space-time kinetics for the spallation neutron source coupled with sub-critical core is of significance on the research of dynamics process and transient simulation studies.IQS/MC is a program for simulation analysis of neutron time-space kinetics utilizing improved quasi-static approximation combined with Monte Carlo neutron transport code.A GUI-based control platform on MATLAB solving amplitude function and shape functions can achieves the dynamics simulation process.This work achieves the simulation of source change and safety rod dropping transient process of lead cooled zeropower experimental reactor by IQS/MC program.
