Experimental and Computational Analysis of a Passive Containment Cooling System with Closed-loop Heat Pipe Technology

摘要

In this paper, a conceptual design of PCSHP is studied using both experimental and computational methods. The rationality of the system design is validated by both the principle experiment and GOTHIC simulation. It is preliminarily judged that the heat pipe technology is feasible to apply to the PCCS of nuclear power plant.The applicability and conservatism of the GOTHIC model is evaluated by comparing the simulating results with the experimental results. The simulation results of the GOTHIC model are in good agreement with the experimental results and the main parameters are within reasonable and credible range. The GOTHIC model can be used to simulate the operating characteristics of PCSHP, optimize system design and provide a foundation model for accident analysis and containment pressure and temperature response analysis.
