We have studied the microscopic magnetic properties, the nature of the 130 K phase transition, and the ground state in the recently synthesized compound Ce$$_2$$Rh$$_2$$Ga by use of $$^{69,71}$$Ga nuclear quadrupole resonance (NQR). The NQR spectra clearly show an unusual phase transition at $$T_tsim130$$ K, yielding a splitting of the high-temperature single NQR line into two well-resolved NQR lines, providing evidence for two crystallographically inequivalent Ga sites. The NQR frequencies are in good agreement with fully relativistic calculations of the band structure. Our NQR results indicate the absence of magnetic or charge order down to 0.3 K. The temperature dependence of the spin-lattice relaxation rate $$1/T_1$$ shows three distinct regimes, with onset temperatures at $$T_t$$ and 2 K. The temperature-independent $$1/T_1$$, observed between $$T_t$$ and 2 K, crosses over to a Korringa process, $$1/T_1propto T$$, below $$sim$$2 K, which evidences a rare two-ion Kondo scenario: The system evolves into a dense Kondo coherent state below 2.0 and 0.8 K probed by the two different Ga sites.

The HTR is a relatively simple Small Modular Reactor design featuring demonstrated robust passive and inherent safety. It responds to the needs of a very large and growing process heat market in most industrialized countries many of which pursue a stringent policy of reducing fossil fuel burn. The manuscript starts from historical developments. This article also highlights the most significant recent achievements of this technology internationally and explains its potential value in a modern energy economy beyond pure electricity generation. The article concludes with an outlook on work towards building demonstration plants, which are required to de-risk private investments and to incentivize deployment.
