Developing and Coupling of Steady State Two-Phase Thermal-Hydraulic Solver PATHS for PARCS

摘要: 本工作开发了PARCS的先进热工水力求解器PATHS，可对沸水堆进行热工水力稳态模拟。与RELAP5的计算结果进行验证，结果表明，PATHS的计算结果与RELAP5的基本一致。将PATHS与PARCS进行耦合，对SMART反应堆及Peach Bottom 2 OECD Turbine Trip基准题进行计算，结果表明，PARCS/PATHS耦合程序计算结果准确有效，能用于沸水堆的稳态物理热工耦合计算。

Abstract: PARCS advanced thermal-hydraulic solver (PATHS) was developed to solve the steady state thermal-hydraulic (T-H) condition of BWR. The Verification and Validation (V&V) of the standalone PATHS code had been completed by comparing with the results of the RELAP5 code. PATHS was then coupled with the PARCS code to provide T-H feedback for steady state and depletion calculations. The V&V of the PATHS/PARCS was also completed via a SMART reactor calculation and the Peach Bottom 2 OECD Turbine Trip benchmark. The results of the coupled calculations conclude that the PARCS/PATHS coupled code is able to perform the steady-state calculation for BWR correctly and effectively.
