Decouple Russia’s Maritime Nuclear Fleet: A Glimpse Behind the Curtain
Nov 4, 2025
Aleksey Rezvoi, a veteran maritime nuclear engineer educated in the Soviet Union, shares his insights on Russia’s maritime nuclear fleet. He reveals the historical significance of the Lenin icebreaker and the evolution of reactor designs to modern small modular reactors (SMRs). Rezvoi discusses the practicalities of Arctic logistics, contrasts Russian operational experience with Western SMR hype, and highlights the importance of system economics. He also addresses safety paradigms, fuel innovations, and the unique challenges of designing reactors for maritime conditions.

Episode notes
Long State Drive Built Maritime Nuclear Mastery
- Russia built maritime nuclear capability from sustained state purpose and Arctic necessity.
- That long lineage created operational expertise and iterative reactor evolution unavailable in many Western programs.
Personal Roots On The Icebreaker Lenin
- Rezvoi's father worked on the first icebreaker Lenin and Rezvoi attended multiple icebreaker launches.
- He used that experience to move from Soviet naval reactors into civilian icebreaker reactor development.
RITM Is A Battle-Tested SMR Platform
- The RITM family is a mature, serially produced integral PWR that doubled as an SMR platform.
- Its factory-style production contrasts with Western SMR promises that often remain theoretical.
