The captured power stations are not of this kind; they are all VVER. There is also the small matter of Ukraine wanting to build more nuclear power stations.

> I was commenting on a statement you made about the cost of upgrade. Somehow you've found a linkage (or absence of a linkage) to war in your response. My comment is about danger of RBK-1000 in real life, which cannot be upgraded to a safe reactor type, because of huge cost of upgrade. > Ukraine gave up nuclear weapons it inherited from the Soviet Union Ukraine can produce more at any time. It's not a hard problem for the country, which developed nukes and missiles for Soviet Union and RF. Currently, the main problem is that Ukraine cannot produce long-range missiles fast enough. > The captured power stations are not of this kind; they are all VVER. Yes, but Russia has RBK-1000 type nuclear reactors in production and they hire former Ukrainian operators to operate their nuclear stations. Do you see a problem here?

  > cannot be upgraded to a safe reactor According to Wikipedia they have been upgraded to be safer (e.g redesign of the control rods). No such a thing as totally safe, except if the thing does not exist. > Ukraine can produce more at any time The question of getting appropriate nuclear materials looms large.

    Safer != safe. > The question of getting appropriate nuclear materials looms large. Ukraine has nuclear reactors. It's not a problem for a nuclear country.
