Effect of damage on gas seepage behavior of …

Potential sites for CO2 and radioactive waste storage are directly determined by the permeability of the rock. Low-permeability rocks act as cap rocks or surrounding rocks to prevent the leakage of gas or radioactive waste. In contrast, to improve production of oil, gas and geothermal energy, the permeability of rock is increased by artificial cracks. Various studies have been extensively ...

Radioactive Waste Management - IRSN

Radioactive waste is generated not only by the nuclear power industry, but also by hospitals, universities and non-nuclear . industries. All the regulations applying to waste in general also apply to radioactive waste. However, radioactive waste emits radiation, which makes it a particular hazard for human health and the environment.

THE USE OF CLAY AS AN ENGINEERED BARRIER …

Geological disposal is the preferred option for the final storage of high-level nuclear waste and spent nuclear fuel in most countries. The selected host rock may be different in individual national programs for radioactive-waste management and the engineered barrier systems that protect and isolate the waste may also differ, but almost all programs are considering an engineered barrier.
