But having to open a submarine every 6 or 7 years to replace the core and its fuel load is also disastrously expensive.

Isn't that the case with LEU reactors?

The Arihant (and subsequent Indian N-subs) are fueled with 40% enriched HEU - which should deliver somewhere between 10-15 years at least.

Either way, going to LEU would be way too prohibitive at this stage.

I think he meant LEU subs do not need to cut open and are easier to refuel. But obviously frequency is higher.

My remark was not intended to promote French submarines, it was about a US rather than a Russian solution. ;)

Don't know if this was known before (certainly not to me):

Seems that inclusion of Lithium-Ion Batteries (LIB) technology is going to be a mandatory requirement under P-75I, alongside AIP.

It's not just mandatory, but it's also supposed to be indigenous.
