With a large fleet like the Soviets had, the cost was the main factor.
New modern compact NPPs on the other hand that are designed to operate for 20-30 years without needing refuelling should make it much more sensible and cheaper operationally to use in larger vessels.
AFAIK the destroyer sized vessels have been shown in conventional and NPP powered models.
AFAIK cruiser and carrier sized vessels were always intended to be nuclear powered.
The Kirov was a testbed, the Slava class was the conventional backup.
The Kirov lacked a powerful enough NPP so it used a combined conventional nuke propulsion system.
The new NPP system is powerful enough to operate on its own for the new ships.
The Soviets designed purpose built vessels... so despite both being similar size the Udaloy and Sovremmeny class destroyers had totally different systems from the ground up including weapons, propulsion, and sensors.
For the Russian Navy their new destroyers will have universal launchers so they can carry anti sub weapons (like the Udaloy SS-N-14, but better) and anti ship weapons (like the Sovremmeny SS-N-22 sunburn, but better) and also land attack missiles (Kalibr... which previous Soviet Destroyers had no equivalent of).
they will also have unified sensor suite to use the different weapon types and unified propulsion systems too...
BTW LSOS is correct... there comes a size where NPP makes no sense except with subs... small nuke subs are quite handy.
