The Influence of Radiation on Confinement Properties of Nuclear Waste Glasses

Table 5

Dynamics of UK189 glass leaching with ²³⁸PuО₂ additive as source of α-radiation [51, 52].

Total dose, α/g	HLW storage time equivalent to dose absorbed (years)	Leaching rate (mg/(cm^2 × day))
0.89 × 10^18	7000	1.6
2.0 × 10^18	250000	2.3
2.7 × 10^18	500000	2.3
3.3 × 10^18	700000	2.3
5.5 × 10^18	1400000	3.2

The leaching rate of unirradiated UK 189 glass (Table 6) was 1.3 ± 0.2 mg/cm² day.
