I believe the Molten Salt Reactor (MSR) is the "Nuclear Equivalent to the Transistor" ©:
The real question about Molten Salt Reactors is not will they be commercialized, but who and when will they do it! If you have not heard about the MSR, do not worry; neither have most nuclear engineers and scientists. If you think this is some sort of 'Government Conspiracy' type information, please read on, or better yet try to visit the last remaining Molten Salt Reactor, the Molten Salt Reactor Experiment (MSRE) at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee (near Knoxville) in building number 7503. The MSRE has been designated "an American Nuclear Society (ANS) Historic Landmark Site" and is also a short distance (~5 kilometers; ~3 miles) from the other ANS Historic Site, the "Graphite Reactor". Unfortunately, the MSRE site is not open to the public, but Oak Ridge's Museum of Energy is supposed to have obtained the "worlds largest machined piece of beryllium" which was to have been half of the core of the Molten Salt version of the Aircraft Nuclear Reactor; the "Fireball". Intrigued, but confused and doubtful? Good! Now is the time to begin your personal "Molten Salt Adventure"; read on & learn!
Here are my worries, and thus the main reason I have created these web pages.
I believe,
The "Eclectic Thread" of this page is; there is superior technology (Nuclear, if you do not know by now!) that is not being fully utilized and because it is not being fully utilized, there are more problems than would otherwise be the case.
The molten salt reactor (MSR) option for burning fissile
fuel from dismantled weapons is examined. It is concluded that
MSRS are potentially suitable for beneficial utilization of the
dismantled fuel. The MSRs have the flexibility to utilize any
fissile fuel in continuous operation with no special
modifications, as demonstrated in the Molten Salt Reactor
Experiment, while maintaining their economy, The MSRS further
require a minimum of special fuel preparation and can tolerate
denaturing and dilution of the fuel. Fuel Shipments can be
arbitrarily small, which may reduce the risk of diversion. The
MSRS have inherent safety features that make them acceptable
and attractive. They can burn a fuel type completely and
convert it to other fuels. The MSRs also have the potential for
burning the actinides and delivering the waste in an optimal
form, thus contributing to the solution of one of the major
remaining problems for deployment of nuclear power.
A brief history of the Molten Salt Reactor (MSR), but the main focus is proliferation of nuclear materials and how the MSR can reduce, if not eliminate, the proliferation possibility via its use of the Thorium Fuel Cycle, as opposed to the current Uranium-Plutonium Fuel Cycle. The destruction of the excess Weapons Fissile Material (Highly Enriched Uranium, HEU, & Bomb-Grade Plutonium) by emplacement in a MSR and converting the excess material's neutrons into proliferation resistant Uranium-233/232 (233U & 232U) is examined. Various postulated proliferation means are discussed and where possible, quantitatively shown not to be possible with MSRs. A good source of references for the interested student of MSRs.

Page 25, "Nuclear Power Reactors", Edited by, James K. Pickard (1957), as part of "The Geneva Series on The Peaceful Uses of Atomic Energy":"The enormous difficulty of choosing a proper path for reactor development is easily seen by estimating the number of conceivable reactor types. With 3 fissionable fuels [233U, 235U, 239Pu], 2 fertile materials [232Th & 238U], 3 neutron energy ranges [slow or thermal, epithermal or resonance, & fast], at least 5 coolant types [2 waters {light & heavy}, sodium, CO2, He, & air], 5 moderators [light & heavy water, graphite, beryllium, & beryllium oxide], and 2 general categories of geometrical arrangement (heterogeneous and homogeneous), there are 900 possible combinations! [3 x 2 x 3 x 5 x 5 x 2 = 900] Of course not all of these are sensible; for example a fast reactor could hardly be cooled with H2O. Even so, there are probably at least 100 combinations which are not obviously unfeasible." NOTE: I added the comments in the brackets []. (Back)
Notes on theTransistor History:
Taken from Britannica CD 97 (search for " transistor" & "Sony Corporation"):Invented by "... three American physicists at the Bell Telephone Laboratories, John Bardeen, Walter H. Brattain, and William B. Shockley" in 1947. They allowed the electronics industry to advance due to "their small size, low heat generation, high reliability, and relatively small power requirements".Morita Akio, one of the founders of theSony corporation, which "In 1957 Sony introduced the world's first pocket-sized, all-transistor radio. In 1960 Sony introduced an 8-inch (20-centimetre) transistorized television set, creating a new market for television". (Back)
