Simulation of the preliminary General Electric SP-100 space reactor concept using the ATHENA computer code

  • 1. EG and G Idaho Inc., Idaho Falls

Description

The capabilities of the ATHENA computer code for simulating the transient thermal-hydraulic behavior of a space reactor have been demonstrated. This represents the first known application of a transient thermal-hydraulic space reactor system model incorporating heat pipes. The current ATHENA heat pipe model is preliminary, excluding its use for calculating very severe transient sequences. Anticipated near term improvements in ATHENA include adding potassium as a working fluid and upgrading the heat pipe model to simulate sonic and entrainment performance limits. Longer term, upgrading ATHENA for modeling the solid-liquid-vapor working fluid phases associated with space reactor startup and shutdown events is anticipated
