Abstract

A dynamic simulation of a large scale cryogenic plant has been conducted, using the Cryogenic Process REal-time SimulaTor (C-PREST) developed as a platform to study cryogenic plant processes. The target plant, Large Helical Device (LHD), consists of a 10 kW class helium refrigerator/liquefier and superconducting coil systems with their supporting structure. Since the development of helium refrigerator/liquefier had been completed, the simulation model was focused on the superconducting coil systems. As the preliminary step for the entire cryogenic plant, the coils are simplified and modeled to have certain temperature efficiencies. Cooldown of the coil systems were conducted from the room temperature to close to 4.4 K, utilizing automatic cooldown sequence programs for the actual cryogenic plant. The paper discusses the computational speed just before establishing the two-phase flow condition and the validity of the simulations compared with the real plant operation.
