Automated enrichment regulation

Currently, I have 1 fast breeder reactor (FBR), where I use enrichment setting 1 as I need all the steam for electricity. When the sun shines, my solar panels take over a lot of the power production, so the automated regulation setting powers down the reactor.
However, I don't want it to power down, I want it to start producing more enriched blanket fuel. That way, I can use my depleted uranium and create plutonium for my space exploration.
Please add an option where the enrichment factor automatically increases when the steam output is full, instead of powering the reactor down, maybe at the cost of extra computing.

You can have 2 FBR - one in 0x mode for power production and 1 in 3x mode to supply first FBR while making plutonium/U20. You even get more power from the same amount of uranium this way.
You can also store excess solar power in the form of heat/steam to supply your network while raining - or just use supplementing woodchip power plant.

Thanks for the reply!
While it would work, it requires me to build a second FBR, which I don't need given my current usage. FBR's take a lot of resources, so I would rather avoid that
