실험 절차

Referring now to the drawing, which despicts the preferred process of this invention, the boric acid liquid wastes, commonly referred to as "evaporator bottoms", generated by a typical pressure water reactor (PWR) are evaporated and concentrated to about a 10 weight percent boric acid solution. The steam resulting from this evaporation process is directed to a vapor clean-up system for ultimate discharge or recycling. The boric acid solution is neutralized with a stoichiometric amount of calcium hydroxide or a similar calcium compound to yield a precipitate of insoluble calcium tetraborate according to the following equation:
