Computer-calculated potential pH diagrams to 300/sup 0/C. Volume 1. Executive Summary. Final report. [PWR; BWR]

This final report summarizes the results of a program to devise a general computer method of estimating potential-pH diagrams for metals in water at temperatures from 25/sup 0/C to 300/sup 0/C. The computer program uses literature data for room temperature and either literature data where available or standard estimation procedures, especially for ions in solution, to calculate relative thermodynamic stabilities of the various possible compounds of an element at temperatures up to 300/sup 0/C. The program identifies the regions in which various phases are stable and presents the stability fields in a potential-pH diagram for a metal in water. In addition to the computer program itself, the report presents numerous potential-pH diagrams for specific elements in water or various temperatures.
