I demonstrate a NEUT-based PHOT reactor on my account, if you want to take a look.
Also, you can make organic SPRK production through the photovoltaic method implemented in TPT - a layer of PSCN and NSCN 1 thick in a lattice can be very good at converting PHOT, and BIZR turns PHOT directly into ELEC.
VIBR also makes for a great heatsink but it also needs coolant - try using it in areas without SPRK.
Or you could use layered CONV(NICE) under VIBR and HEAC.
The battery one, the other won't matter as much as LITH can overload and melt more eaisly.
Triston17879: the battery one or the one next to the electrical shenanigans?
Your LITH coolant is too weak, use NICE or FRZW.
