Nuclear waste management is a key engineering issue facing countries that use nuclear power. Spent nuclear fuel is radioactive and must be isolated from the biosphere for long periods of time to allow natural radioactive decay of long-lived radionuclides. Deep geologic repositories employing a multi-barrier design strategy are considered the safest solution to isolate the waste. Significant research into deep geologic repository concepts for nuclear waste management has been conducted internationally. Dr. Rod Read has extensive experience in international projects addressing nuclear waste management, including 10 years of world-class research at Atomic Energy of Canadas Underground Research Laboratory in Canada. Examples of typical projects include the following:
