Fission's amazing potentially is nerfed by three main things: proliferation risk, meltdown risk, and waste handling. These are all solved problems but dramatically raise the cost (you need armed guards, and the reactor has to be built to withstand a 747 strike, etc etc). The fuel cost is a very small fraction of the price of nuclear.
If you can eliminate or reduce the need for armed guards and mountains of red tape, this has the potential to solve many of fission's problems while providing the same benefits (unlimited zero carbon power with dirt cheap fuel).
