PANGU code for pebble-bed HTGR reactor physics and fuel cycle simulations

Abstract

PANGU is a modern computer code for pebble-bed High Temperature Gas-cooled Reactor (HTGR) physics analyses and fuel cycle simulations, developed by Institute of Nuclear and New Energy Technology (INET), Tsinghua University. This paper gives a comprehensive review on PANGU code’s features including its calculation scheme, methodologies, models and capabilities. Numerical tests are presented for typical pebble bed reactor cases, to verify PANGU code’s applicability. It demonstrates that PANGU code is promising for physical designs of traditional and new-conceptual pebble-bed HTGRs.
