Can you explain why there is no reference to “thorium” in the article? The fuel is said to contain uranium. However, the words “molten salt” are used, which is customarily used in a thorium reactor. Is this a different process?

There are non-thorium molten salt reactor designs out there and have been since 1954: http://en.wikipedia.org/wiki/Molten_salt_reactor

Re: “no reference to “thorium” in the article”

From the article:

“The IMSR uses normal low-enriched uranium but can also use thorium and other actinide elements as fuel.”

Also, an interesting and well written side link you may not have noticed:
