Implementation of the library of properties of sodium vapor on the basis of the s (p, h) formulation in the thermohydraulic module of the SOKRAT-BN integral code

The paper presents the results of incorporating into the SOKRAT-BN code a new library of properties of sodium vapor on the basis of the s (p, h) formulation: the entropy of sodium vapor as a function of pressure and enthalpy. A double increase in the computational speed and a good agreement with the results of the previous version of the library of properties of sodium vapor are attained.
