Benchmark Validation of Resonance Calculation in Advanced Neutronics Lattice Code KYLIN-Ⅱ

Several benchmark problems were validated for the resonance calculation module of neurotics lattice code KYLIN-Ⅱ, including cell problem, IAEA problem, thorium based assembly problem, multi-layer bushing fuel assembly problem, burnable poison lattice problem, supercritical water reactor fuel lattice with large water cavity, and AFA3G fuel assembly with Gadolinium problem. The validation results show that the resonance calculation module in this paper is suitable for complex geometric structures such as square assembly with fuel rod lattice and planar fuel assembly and hexagonal assembly. Besides, it can correctly calculate the resonance problem of complex materials containing uranium, thorium, poisons, etc. It satisfies the requirement of future engineering application.
