AbstractAbstract
[en] Radioactive wastes containing borates are solidified by embedding in bitumens by adding NaOH to the waste concentrate. Thus, at a Na/B molar ratio 0.25 or 0.75, pH 7.3-80 or 9.8-10.2, and 20.degree. or >80.degree., respectively the solid gives a good leaching stability without crystalization. (orig./PW)
