ANTHEM~(TM) NSSS Model Validation

摘要

This paper describes recent validation results of ANTHEM2000~(TM), a two-phase thermal-hydraulic model developed by CAE Electronics Ltd. for realtime simulation of NSSS and fossil boilers. The thermal-hydraulic model is an unequal temperatures, unequal velocities model. A local momentum equation is solved for each link and the global pressure assumption is not used. The drift flux formalism is used to determine local phase flows. In this paper, CAE reports ANTHEM2000 validation resuits against. plant and RELAP 5 simulation data, obtained during Factory Acceptance Testing for the Kr?ko full scope simulator.
