英文摘要	Reactor Pressure Vessel (RPV) damage determination is important for reactor (power plant) safety and power economics, as its determination informs plant integrity and end-of-life extension. Irradiation damage determination is indirectly derived from the measurement/calculation of neutron fluence at or close to the pressure vessel system. The labyrinth procedure for experimentally determining the fluence by online operating plants makes theoretical (calculation) applications attractive. However, the calculation process must be validated via benchmark analysis, particularly according to the U.S Nuclear Regulatory Guide (Guide 1.190) for RPV dosimetry methods. One such related benchmark is the Pool Critical Assembly (PCA) of Oak Ridge. In this work, a detailed 3D model of the PCA facility and the calculated threshold reaction rate(s) have been achieved using the SuperMC code. Since iron (i.e., Fe-56) forms the major components of RPV, its evaluated data is key for benchmark calculations. Therefore, the calculation compares the Fe-56 data from ENDF/BVII.1, ENDF/BVIII.0, and a modified Fe-56-data by CIELO group (postENDF/BVIII.0). The calculated threshold reaction rates were achieved within 5%-10% deviation. The deviations were also identified to be dependent on the selected detectors' energy response spectrum. A detailed demonstration of displacement-per-atom rate (dpa/s) calculation is also presented, it showed contribution of about 5% and 95% for neutron energy <0.1 MeV and >0.1 MeV respectively.
