ATHENA model for 4 x 350 MW(t) HTGR plant side-by-side steel vessel prismatic core concept

Creators

Description

ATHENA is a computer code being developed at the Idaho National Engineering Laboratory under US Department of Energy support. The code will provide advanced best-estimate predictive capability for a wide spectrum of applications. The code has capability for modeling independent hydrodynamic systems which can currently include water, helium, Freon-II, idealgas, lithium, or lithium-lead as fluids. ATHENA was modified to allow point reactor kinetics evaluations for two nuclear reactor cores. Capability for specifying gas circulators was added and representative homologous curves were added for a helium circulator. A full system model was developed for a High Temperature Gas Reactor modular concept with a full secondary system model. The code capability to model the complete system was demonstrated and a representative transient for a circulator coastdown without reactor scram was modeled and evaluated to the point of flow stagnation
