As you know, raw natural uranium is used with CANDU technology. During the cycle of a fuel rod in a power reactor, just 1% of the potential energy from CANDU fuel rods is used, and the natural uranium aspect is one of the reasons why CANDU technology enjoys the superior level of proliferation resistance.
Given that only 1% is used, which means that 99% of the natural uranium in a rod is not utilized, why is deep geological storage preferable to the above ground storage, which is now in place in some areas? Because in the future when the price of uranium is significantly higher, it may be cost effective to retrieve the spent fuel rods and use some of that 99% of potential energy that's untapped. Do you not see any benefit in perhaps looking at above ground storage and also in being able to monitor more closely the decay of the radioactivity?
