Calculated Effects of Dissolved Gases on the Thermodynamic Properties of Hanford N Reactor Primary Coolant

摘要

It has been noted that for present and anticipated modes of operation the Hanford N-Reactor primary coolant may bear thermohydraulically significant amounts of dissolved hydrogen, nitrogen, and ammonia. To investigate this possibility, calculations were made of the specific volume and specific enthalpy of aqueous primary coolant from available data and reasonable approximations over the necessary ranges of temperature and pressure. A computer program which produces a steam table of these properties, as well as compositions, has been coded to provide tables of the bubble line, dew line, superheated-vapor - compressed liquid, and two phase-to-20% void regimes from 32 exp 0 F to 630 exp 0 F and from 14 psia to 2100 psia. This program will provide the tables for any inputted coolant composition of water with 0.01 to 200 ppM NH sub 3 , 0.01 to 50 ppM H sub 2 , and 0.01 to 150 ppM N sub 2 , or so long as the mole fraction of water remains above 0.999. Alteration for other water chemistries is not difficult. (ERA citation 07:056953)
