Mostly based on thorium, but they seems just use enriched uranium (U-235)... So potentially you can construct an atomic bomb fairly easily out of this fuel.

Very mildly enriched uranium, at just 1.8% U-235: http://transatomicpower.com/products.php http://transatomicpower.com/products.php That's less enriched than conventional reactor fuel. Using thorium doesn't necessarily prevent proliferation. If you have a design that separates protactinium, you can let that decay to pure U-233, which by at least some accounts is easy to turn into a bomb.
