There is no Thorium reactor, only a Thorium fuel cycle, which is even
more uneconomical than mainstream nuclear power, if they manage to
make it work at all.  For the THTR-300 (read
<https://de.wikipedia.org/wiki/Kernkraftwerk_THTR-300>, using a
translation service if necessary; it is much more informative than the
article in en.wikipedia.org) <30% of the energy it produced were due
to the Thorium fuel cycle, the rest came from U-235).  Looking at
<https://en.wikipedia.org/wiki/TMSR-LF1>, its fuel consists of Uranium
with 19.75% U-235 (i.e., 80% U-238) and Thorium.  Given that the
THTR-300 used Uranium with 95% U-235, I expect that the contribution
from Thorium in the TSMR-LF1 will be even less.

However, the Chinese are very strong and have a good growth path on
wind and especially solar power, with more than twice the amount of
wind power than nuclear power in 2025, and also more than twice the
amount of solar power than nuclear power.  Solar power surpassed
nuclear power in 2022, wind power surpassed it in 2013
<https://en.wikipedia.org/wiki/Renewable_energy_in_China#Renewable_electricity_overview>.

Back to the RISC-V rant: It's interesting that RISC-V acquired some
warts from the start.  I doubt that these warts will prevent it from
succeeding.  The winner-takes-all principle may, but we will have to
see about that.

In any case, a pointer to that rant might have received more interest
in comp.arch.
