Zero. Russia has plenty of regular weapons to level Ukraine and big part of Europe (look at thermobaric bombs). It also has industry and resources to produce such weapons for long period of time.

And it considers Ukraine ethnically related. Many Russians have relatives in Kiev etc.. Using nukes on Ukraine would be huge political problem.

It is FUD spread by trigger happy westerners, who want to normalize nuclear war!

You'd think that invading Ukraine would also be looked upon negatively then, no? You also say that like it isn't Putin who has been repeatedly threatening nuclear escalation.
