Atomic Insights: Challenging established paradigms in one of the world’s largest industries

Read the comments. Rod Adams is positively apologetic for Leslie's gross technical errors. Would that he showed such latitude to other designs.

I see there is some more papers posted at the bottom of their main page, Neutronics White Paper v1.1 and ORNL-TM-2017-475, that shed more light on their moderator rod design. Appendix A in Neutronics White Paper v1.1 shows a rod radius of 1.25 cm, and silicon carbide in Table A.1 as part of the material composition. In ORNL-TM-2017-475 shows the cladding thickness at 0.1 cm in Table 1.

Seems to me that these folks are betting the farm on the ability of this cladding to survive the harsh environment of the reactor core. And I'm not sure what is driving such faith, other than "it would be really great if..."

Oh well.

Transatomic winding down

Is the winding down of Transatomic Power also not a tacit admission that the unique selling point of their MSR design, the zirconium hydride moderator, is basically unworkable ?

If you really want to go for a thermal MSR, perhaps a calandra design with fuel in tubes and a low vapor pressure organic moderator/coolant in the drum may be the right approach. A plutonium-thorium fuel could meet the requirement. Higher the coolant temperature, higher the thermal efficiency.

Transatomic Power to Open Source IP Regarding Advanced Molten Salt Reactors
Transatomic owns just three patent applications.[3] All three are generally directed to molten salt reactors:

U.S. Patent Publication No. 2013/0083878: describes a molten salt reactor using hydrides and/or deuterides as a moderator.
U.S. Patent Publication No. 2015/0228363: describes fuel cladding properties for use in a molten salt reactor.
U.S. Patent Publication No. 2016/0217874: describes a molten salt reactor using a fluoride fuel salt and a hydride moderator.
Two of Transatomic’s applications (Nos. 2015/0228363 and 2016/0217874) were rejected by the U.S. Patent and Trademark Office (USPTO) on the basis that the inventions described in those applications were not new and non-obvious when compared to existing MSR technology. Those applications were abandoned by Transatomic prior to the open source announcement.[4]

Transatomic’s lone remaining patent application (No. 2013/0083878) has been rejected by the USPTO five times, also on the basis that the invention is not new and non-obvious when compared to existing MSR technology. With Transatomic’s suspension of operations it is uncertain if this application will ever issue as a patent.
