RADIOACTIVE WASTE MANAGEMENT

Glass-ceramic wasteforms containing calcium neodymium(cerium) oxide silicate [Ca2Nd8 - xCex(SiO4)6O2] were synthesized to immobilize lanthanide oxide wastes generated from pyro-processing.

RADIOACTIVE WASTE MANAGEMENT

Silver tellurite glasses with melting temperatures < 700 °C were prepared to immobilize the 129I that normally volatilizes during high-temperature melting. Glasses have densities of 6.31 ± 0.1

RADIOACTIVE WASTE MANAGEMENT

 A new alkali-alumino tellurite glass composition was developed to immobilize highly-volatile technetium (Tc) wastes generated from the pyrochemical processing technology. Tellurite glass can

RADIOACTIVE WASTE MANAGEMENT

Cs+ captured fly ash filter waste from pyro-processing was immobilized by alumino-borosilicate glass waste form. Produced glass specimens were irradiated by electrons in order to simulate t

RADIOACTIVE WASTE MANAGEMENT

Radioactive iodine is one of the major constituents among fission products released into the environment from damaged containment at nuclear power plant (NPP) during severe

RADIOACTIVE WASTE MANAGEMENT

Efficient and rapid removal of radioactive contaminants is crucial when they are released into the environment as a result of severe nuclear accidents. In addition, various methods have been developed

RADIOACTIVE WASTE MANAGEMENT

Most of nuclear power plants (NPP) and their yard storage facilities are located on or close to the shoreline, because the nuclear power plants need for cooling water.  As a fission product (90Sr

RADIOACTIVE WASTE MANAGEMENT

The radioactive waste includes radioisotope such as 129I and 131I whose half-lives are t1/2 = 1.57x107 years and t1/2 = 8.02 days, respectively. These iodine has harmful effects to humans through exte
