I've just been looking at the Obninsk Reactor recipes in the light of your comments above.
Once you have used the Yuoki power systems enough to understand the concepts behind them, it becomes clear that the first recipe is intended to be the main recipe. This generates enough Hydraulic Fluid to keep two of the biggest generators producing power constantly.
The other two recipes are primarily intended to produce the different upgraded fuels for the process as the Obninsk Fuel Cells are consumed extremely rapidly.
Given that these are their primary purpose, the generation of Hydraulic Fluid then becomes a by-product of the process, which can be added to the power system to power extra generators in the system.
The intention is to design a loop which converts prepared fuel into the irradiated form is washed to create the finished fuel cell and then inserted into an Obninsk Reactor using the 1st recipe to generate hydraulic fluid to power a turbine.
So, sadly, your idea wouldn't work IMO.
