    6 new Kalinas for Baltic Fleet?
    6 new Kalinas for Nothern Fleet?
    Ladas not Kalina.

    My interest in the historical split is because recent history prior to the BSF 6 they had most in North & Pacific, presumably guarding SSBNs? -> may want to repeat that rather than even groups of 6.

    According to soviet/russian strategy, SSKs are to be used for "bastion defence" - defence of littoral areas from which SSBNs operate, as well as for disruption of commercial routes throughout the oceans.

    That was true when they had more than 300 subs in the 70s and 80s. Now don't even have enough to protect their coast.

    Back then Amiland had 150+ subs, now around 50.

First nuclear reactor was made for purpose of Manhattan project in early 40s. So, what are nuclear batteries to produce electricity by nuclear fission, without primary circle to heat water and without need to heat water in secondary circle and power turbine by steam. Turbine than runs E-generators. Fuel cells are not nuclear batteries. dunno
    You forgot about naturally occurring fission. It was Henry Moseley in 1912 who created the first beta cell, placing radioactive Radium inside a sphere of silver, to collect charge from the beta radiation. Here are a couple of links which you may find interesting...

    Alpha and Beta-voltaics are not great at high current applications, but are more energy efficient than RTGs, have greater energy density than electro-chemical cells, and decades long lifespans. There was an article circulating sometime back in June which discussed recent Russian research into radioactive nickle betavoltaic batteries.

    Rutherford split the atom in about 1917 or so and was largely responsible for exploring and identifying the parts of an atom.

    Rather important New Zealander he is... much like Sir Edmund Hillary.

    They are and have worked on a wide range of nuclear power generation systems from rather small up to rather large... large to power ships or major land based power generation, but also small for use in satellites and space stations and colonies on other planets where solar is not so reliable...
