Abstract
Vitrifications process one of the important methods to immobilize nuclear waste. In this research nuclear waste (Strontium Oxides) with molecular weight (5%) was immobilized by vitrification methods in two types of borosilicate glass (c-type) which are glass and glass-ceramics. To investigate the physical, chemical and mechanical properties of glass and glass-ceramic after immobilize nuclear waste these samples irradiated by gamma ray radiation. Co-60 was used as gamma a irradiation with dose rate 0.38 kGy/hr for different period of time. It’s found that gamma radiation affected the glass and glass-ceramic properties. From phase analysis by the x-ray diffraction for glass-ceramic samples proved that at doses 343kGy change the crystalline glass to amorphous glass. A conclusion from these ionization studies is that the limited magnitude of Strontium ion leaching associated with ionization damage does not appear to pose any direct problems for the safe storage of nuclear waste glass.
Highlights
Nuclear waste pollution is one of the biggest problems effecting in our environment and in our health
The density calculated for samples before exposure to gamma ray radiation and after irradiation with different doses is shown in the Table3
The influence of radionuclide decay on vitrified nuclear waste may be manifested by density changes
Summary
Nuclear waste pollution is one of the biggest problems effecting in our environment and in our health. Researchers focus about how to disposal from high-level waste because it emits high level radiation, and the isotopes diminishes requires hundreds or thousand years, so it represent the biggest hazard from another type waste so this will required to find suitable safety method to store it for this long-term of time, after invariance failed store it in the tanks because corrosion as a result of long-term preservation and this cause leakage of ions to the underground[2]. Experimental work The borosilicate glass C-type (Celsian) prepared from the list oxides insert in the Table. Experimental work The borosilicate glass C-type (Celsian) prepared from the list oxides insert in the Table1 This table contains weight percentage and the stage of oxides used for proper base glass.
