Good point about MSR which is most probably what government is eyeing on since it's promoted by Terra Power founded by Bill Gates.

The Downsides of MSR:
Molten salt reactors are a bad idea. The Molten Salt Reactor Experiment’s history is riddled with extensive problems, both during its operational lifetime and the half century thereafter. These problems were not accidental but a result of the many material challenges faced by the reactor itself.
Any other molten salt reactor will encounter these problems too. France’s
Institut de Radioprotection et de Sûreté Nucléaire,
the Nuclear Innovation and Research Office in the United Kingdom, and other research laboratories have all drawn this conclusion. According to the Institut de Radioprotection et de Sûreté Nucléaire, “
numerous technological challenges remain to be overcome before the construction of an MSR can be considered.”
Should molten salt reactors ever be constructed, they are unlikely to operate reliably. And if they are deployed, they would likely result in various
safety and security risks. And they would produce several
different waste streams, all of which would require extensive processing and would face disposal related challenges. Investing in molten salt reactors is not worth the cost or the effort.
