> In 1972, after four years of operation, her reactor was refuelled. She had covered 250,000 nautical miles (463,000 km) on 22 kilograms of uranium.
- moffkalast 4y agoHmm, that seems oddly short. Don't nuclear subs regularly go 20 years between refuelling? But then again they use weapons grade enriched fuel so that's probably why.
- LargoLasskhyfv 4y agoYes, in the german version of the article this is mentioned. It was mostly a small version of a light water reactor using U235 enriched to about 5%, like the larger versions on land used in NPPs.
- GekkePrutser 4y agoInteresting choice, also makes it much less of a target than a military sub reactor running on highly enriched uranium. Considering these icebreakers are probably not very well guarded this is a very good decision for nonproliferation purposes.
- LargoLasskhyfv 4y agoUhm, I referred to the german experimental ship from the 70ies. I actually don't know which type of reactor and fuel the russian icebreakers are using. Back to the only enriched to 5%, it would still make a good dirty bomb. But probably very unhealthy and impractical to assemble for the 'target audience' interested in such things. Edit: So it says https://en.wikipedia.org/wiki/OK-150_reactor https://en.wikipedia.org/wiki/OK-150_reactor , three of them. Each using 150.7kg U235 enriched to 90%.
