A study on the characteristics of final glass form of radioactives surrogate waste

The results of technical supporting to trial burn tests of PAM system at KAERI site and the results of a series of test to demonstrate the system applicability for the treatment of combustible, non-combustible, solidified resin. The characteristics of final and vitrified products was evaluated to density, microhardness, XRD, thermal expansion coefficient. The test results were found that density as 2.42∼2.95glcm3, microhardness as 5.48∼5.83GPa, thermal expansion coefficient as ∼10-6 .deg. C. The results for XRD also showed that vitrified product were satisfactory the required quality and accorded with specific curve of normal amorphous material. Vitrified product in these tests is similar or excellent compared with others in foreign countries
