Availability Notice


TRACE code developed by US NRC is an advanced thermal hydraulic system code for nuclear power plant safety analysis. The feature of 3-D reactor vessel simulation in TRACE allows complex flow modeling and this kind of vessel is employed in Lungmen TRACE model. PARCS is a multi-dimensional neutronic simulator which is able to incorporate a 3-D reactor core with one-to-one fuel assembly simulation for the realistic representative. The state-of-the-art is that PARCS is capable of being coupled to TRACE, which provides the temperature and flow field information to PARCS during calculations. In this research, the TRACE/PARCS model of Lungmen nuclear power plant is established first. Then, the TRACE/PARCS model is used for two transient analyses - 3 RIPs trip and HPCF inadvertent startup. These events could test the ability of the coupling of TRACE and PARCS. Moreover, SNAP, a user-friendly interface developed by the US NRC and APT, provides users a graphical working environment and enables to animate the simulation as an alternative presentation of calculation results.
