Australian and Chinese researchers have recently been working on the development of new alloys for molten salt reactors - NiMo-SiC:

Reseachers at the Massachusetts Institute of Technology are also busy with carrying out research, which could be important for MSRs - measuring radiation damage in materials in a more efficient manner, using spectroscopy:

LFTR Pony on facebook posted this article, too. And here.

Although there are no commercial MSRs in operation, there is an MSR and thorium energy research and development program at the Shanghai Institute of Applied Physics (Sinap), with which Antso has a partnership agreement.
Excuse, and the US Department of Energy's Oak Ridge National Laboratory—quite humble in being anonymous in this deal . . .
OAK RIDGE, Tenn., March 17, 2015—Representatives from the Oak Ridge National Laboratory (ORNL) and the Shanghai Institute of Applied Physics (SINAP) are meeting at ORNL this week as part of an agreement between the two institutions to work together on the advancement of salt-cooled nuclear reactor technologies.
Two years ago. I hope the news is that Flibe Energy of Huntsville will have its working LFTR sooner than the Chinese, Russians, and the others.

Does the silicon transmute to phosphorus and how would that affect the characteristics of this NiMo-SiC alloy? Above my pay grade.

Apparently not. The absorption spectrum of 28Si, which is 92% of natural silicon, is only 0.177, better than most metals, and similar to natural zirconium. 29Si and 30Si are stable isotopes, and have slightly lower absorption spectra again.

It would be very interesting to see the data of this new material.

Mechanical properties.
Thermodynamic properties
Manufacturing properties as weldability.

Are there any technical data about this new material published?
