It's a dual-use reactor: plutonium and electricity production (200 MWe).
> Any reactor produces some amount of energy
But not electricity. For that a power plant has also turbines, generators, etc., ...
The US for example had no electricity production in the early reactors for Plutonium production.
But the US Hanford N produced both Plutonium and electricity for the commercial grid for 21 years...
Yes,but if you don't do that, you're just wasting energy. The US realized that, which is why they added electricity generation to the N Reactor. Both were still designed to create plutonium, and would not be built without the aim of nuclear weapons.
It's like saying we grow the same corn for the edible part and for biomass. While technically true, the edible part is driving the production.
