Abstract

Abstract

On the basis of 2D/1D coupled characteristics transport, the treatment method of cusping effect of control rod movement are studied, including adaptive mesh method and bidirectional homogenization method. In the bidirectional homogenization method, the homogenization error is reduced by establishing radial flux profile and axial flux profile. The control rod movement function is implemented in high fidelity numerical reactor code NECP-X. The treatment of the control rod cusping effect is verified by the C5G7-TD benchmark and VERA #5 benchmark. The numerical results show that the adaptive mesh method and the bidirectional homogenization method both have high accuracy in the calculation of control rod value and core power. The control rod cusping effect caused by bidirectional homogenization can be well corrected by flux profile.
