This is the 0.16 fix for hopewelljnj's AdvancedNuclear.
https://mods.factorio.com/mod/AdvancedNuclear

The mod changes the original multiplied use of the items to reuse the original nuclear reactor, heat exchanger, steam turbine and heat pipes.

recipes:
nuclear reactor 2 = 1multiplier nuclear reactor + 100multiplier processing units
heat exchanger 2 = 1multiplier heat exchanger + 10multiplier processing units
steam turbine 2 = 1multiplier steam turbine + 10multiplier processing units
heat pipe 2 = 1*multiplier heat pipe

The multiplier can be set via mod settings.
