Title: Hydrolysis and Radiation Chemistry of the DGAs

Abstract

This document was prepared to meet FCR&D level 3 milestone M3FT-16IN030104052, “continue the study of the short chain compounds,” and, “ study the radiolysis of the non-symmetrical DGA (D3DODGA)….,” under the Radiation Chemistry FCR&D work package. Toward these goals, the short chain DGA, tetraethyldiglycolamide (TEDGA) was investigated for its hydrolytic stability in HNO3 solution, with comparisons to the less oxidizing mineral acid HCl. Initial gamma-irradiations were also performed on DGA solutions, to inform a more detailed investigation of several short chain compounds anticipated for FY17. The hydrolytic and radiolysis behavior of TEDGA is of interest for two reasons. First, previous long chain DGA radiolysis was conducted in dodecane solution since the long chain compounds are soluble in that diluent, and new radiation chemistry is expected in the aqueous environment due to reactions with •OH radical. The second reason is that this water-soluble DGA has been proposed for use as a stripping or holdback agent in both European and American fuel cycle scenarios. Therefore, this work was performed in collaboration Forschungszentrum Jülich (FZJ), and the European SACSESS program. Additionally, results are presented here regarding the radiation of chemistry the non-symmetrical DGA didodecyldioctyldiglycolamide (D3DODGA), for comparison to previous work with symmetrical DGAsmore » such as TODGA and TEHDGA. This was also conducted in collaboration with researchers in the SACSESS program.« less
