Opportunities exist for the diversion of weapons - usable material at the front end of the fuel cycle, during which natural uranium is enriched to make reactor fuel.
Until these risks are properly mitigated and the complete nuclear fuel cycle — from the mining and milling of uranium to the final disposal of radioactive wastes — is sufficiently regulated, nuclear power should not be a leading strategy for diversifying America's energy portfolio and reducing carbon pollution.
Dr. Walker highlighted the vulnerability of the entire nuclear fuel cycle — from uranium mining to nuclear enrichment to commercial nuclear power to spent fuel storage, transportation, and finally reprocessing.
A: The way the fuel cycle is done now is: you mine uranium; you purify the metal; you convert it to oxide; you put it in a reactor in the form of pellets; it stays in there for about three years; you take it out, and you try to find someplace to put it.
The way the IFR fuel cycle would work would be: you could start with mined uranium, or you could start with fuel for present day reactors.
Actually, if you properly do the math - and count if you count the whole nuclear fuel cycle, not just the power plant, not just the core of the reactor, but the occlusion zone, the uranium mining and so on, it turns out that wind power uses hundreds or thousands of times less land per kilowatt hour, then nuclear does.
