Unless you're saying that Chernobyl was a Soviet initiative... which wouldn't even be super wrong strictly speaking... But if that's not what you meant, and I'm pretty sure it wasn't, then no not really. I think it's hard to overstate how much Chernobyl scared people. If anything the Soviets had everything to win by making nuclear look safe back in the cold war. If you look at Soviet propaganda, nuclear technology was very prominent and a key part of the international image they wanted to project.

But a West without nuclear power generation benefited the USSR.

The country that became Russia, which is a huge proponent of nuclear power...?

I would think Russia makes more money selling fossil fuels than by promoting nuclear energy.
