Abstract
The data in this report should enable proposed methods for the introduction of boric acid into the Phebus-FP tests to be assessed. Boric acid chemistry is reviewed in the condensed, vapour and aqueous phases. The chemistry of concentrated aqueous solutions of boric acid is complex, involving polyborate species resulting in enhanced acidities. Equations are presented that allow the partition of boric acid between the vapour and aqueous phase to be calculated at different boric acid concentrations. The volatility of boric acid is enhanced significantly in the presence of steam. Equations are given that allow the effective vapour pressure of boric acid to be determined as functions of the water vapour pressure for temperatures in the range from 723 to 1000{sup o}C. These data are confirmed by experimental studies designed to simulate specific aspects of the conditions in the Phebus-FP tests. (author).
