After a while a finally found time to work on Lenin, the first nuclear merchant ship and first nuclear Icebreker.
She was the proud of the soviet era. She had at least 2 major nuclear accidents as reported lately and even documentation is quite uncomplete.
The first accident happened in 1965 and the was stopped until 1967. The two reactors where replaced with 3 newer one, smaller but pore powerful.
During this works probably was modified also the upper structure with an extra floor added (possible due the total weight reduction of reactors).
Here is the version as commissioned (probably): any comment and/or suggestion is welcome.
