Like I said, nobody's ever run a thorium-cycle liquid-salt reactor and there is no Santa Claus. As for a "thorium breeder blanket" add-on to the Oak Ridge reactor, huh? The LFTR concept mixes thorium into the molten-salt stream, breeds it up to U-233 and then fissions it within a moderator to slow down the neutron flux. There is no separate blanket, it's all in one stream, salt, kickstarter fuel (U-233 or U-235/Pu-239), thorium and waste products all at 700 deg C and more, mindbogglingly radioactive, radiochemically very complex and being continuously moved around lots of piping and heat exchangers and chemical processing plant and it has to generate electricity at about 5 cents per kWh to be competitive.
Any such reactor is going to require a neutron flux way higher than the ORNL reactor ever experienced, a mix of fast neutrons to do the breeding and slower neutrons to fission the resulting U-233. This isn't a problem for existing well-tested light-water and heavy-water reactors delivering about 15% of the world's electricity demand right now, of course. In their case the ceramic fuel sits in zirconium tubes and water circulates around them to transfer heat and in some cases moderate the neutron flux, no fast neutrons specifically required for breeding purposes (although some breeding does happen anyway). Much simpler and more reliable, no explosives required.
I agree that uranium will not be scarce for decades, at least one conventional and proven light-water/heavy-water reactor operation cycle of about 60 years. It's possible it would never be scarce at all if the process to extract from seawater can be operated commercially -- it's been tested, its cost is estimated at about three or four times the price of conventionally mined uranium today. Some countries don't have much uranium within their boundaries so ongoing supply is not guaranteed. India is one such country hence their interest in developing a fuel cycle involving thorium for their heavy-water reactors. They're still building and operating conventionally-fueled reactors too though.
