Believe it or not, but a supercomputer is way slower than mining with ASICs. These ASIC chips are specifically developed to target the math needed to solve these complex algorithms. This is also not the first time someone tried this with the so-called supercomputers, it was done before and they failed miserably.

When you want maximum results, you use specialized tools. ASIC chips was developed specifically for Crypto currency mining and will give you much better results than the most powerful computer in this world.
And ASICs are usign way less juice compared to supercomputers
Anyway, I don't catch the point, the supercomputer was a part of the nuclear power plant, or the nuclear power plant was needed to feed the supercomputer with energy?
What I always quote in connection with russia and bitcoin that last year one of their bigger cities was trying to invite the chinese miners, offered to re-open their old dodgy nuclear power plant to feed the ASICs farms and the climate is so cold that the airco is not needed to run the mining farms, it's enough to open the windows
