Possibility of derivation of energetic state variables from simplified BWR thermal state equation for water and water steam

Abstract

Thermal equation of state, along with the basic heat capacities are the most important documents needed to description the behavior of substances. Any other thermodynamic properties of a substance can already be deduced from these relations. The aim of this paper is to derive the dependence of energetic properties of water steam on the temperature and density from simple thermal equation of state based on original BWR thermal equation of state which describes the behavior of H2O in the gaseous phase in region of usual pressures and temperatures with sufficient accuracy.
