I was designing emergency backup reactor for remote parts of my factory and came up with this design.
Small and compact
Easy to blueprint
280MW continuous power
Supplied with water from just one side
No tanks or circuits
Almost symmetric
Four roboports are needed just for symmetry, one is enough to provide required logistics coverage.
