There was another molten-salt reactor, in addition to the ARE and the MSRE.

It was the PWAR-1 (Pratt & Whitney Aircraft Reactor-1), a critical assembly operated at high temperature but at very very low power (essentially zero). It achieved criticality on February 5, 1957 and was run for several weeks (not specified) before being shut down and disassembled. Its design was very similar to the proposed Aircraft Reactor Test (ART, or "Fireball") that ORNL has proposed to build under the Aircraft Reactor Program.

ORNL-2536: A Zero-Power Reflector-Moderated Reactor Experiment at Elevated Temperature

Alas, the molten-salt reactor work under the Aircraft Reactor Program was cancelled in September 1957 and further work at ORNL on the ANP was done in support of other (solid-fueled) reactor concepts before the ANP itself was cancelled in 1961.

Very little mention of the PWAR-1 was made in ORNL quarterly reports on the aircraft reactor program. Brief mention is made in ORNL-2157 (pages 265-267) and ORNL-2274 (pages 131-132).

Despite its modest ambitions and short operating duration, it was an actual critical molten-salt reactor.

Kirk that is amazing, number three of the two msrs.

I will update the molten salt reactor wiki entry with this information and reference.

Are you going to talk to some old guy at Pratt and Witney about the PWAR-1? Surely, any patents have expired.
