摘　　要：为完成某废物库回取、整备设施中整备车间固体废物的整备,满足车间水泥固定系统的工程应用需求,对初期实验室研究的中低放固体废物固定配方在该系统上进行200 L废物桶和2 m^3废物箱的工程验证试验,考察该配方的固化体性能,如固化过程中的温升、固化体均匀性等,并确定加料顺序和搅拌时间等工艺参数。结果表明,生产的固化体符合行业标准(EJ 1186—2005)的要求,满足国家废物运输和处置要求。A immobilization cement-mortar formulation was studied with retrieval low and intermediate level radioactive solid waste in order to test the waste repository retrieval and conditioning facility.The engineering verification test was carried out on 200L drums and 2m^3 containers based on the immobilization cement-mortar formulation to make it applicable in the cement-mortar mixing workshop.The performances of the waste form were inspected,including temperature rise,uniformity of the waste form,feeding sequence and mixing time.The results show that the performances meet the standards of characterization of radioactive waste forms and packages(EJ 1186-2005)and the requirements of national waste transportation and disposal.
