The geochemical role of B-10 enriched boric acid in cemented liquid radioactive wastes

Abstract Boric acid is a significant radioactive waste generated during the operation of nuclear power plants. Cementitious materials have been widely studied for immobilization boric acid. The generally used natural has replaced by enriched geochemical reasons and are expected to varied behaviors in cementitious matrices. Results showed that simulated enriched/natural liquid wastes mostly contain boron $${\mathrm{B}(\mathrm{OH})}_{4}^{-}$$ B ( OH ) 4 - $${{\mathrm{B}}_{5}{\mathrm{O}}_{6}(\mathrm{OH})}_{4}^{-}$$ 5 O 6 ionic forms, but mass ratio these species higher solutions. In function with concentration acid, solidified show different mineralogy.
