Steps to reproduce:

1. Build 3x3 basic reactor with 4,000mB fuel capacity
2. Insert 8 Yellorite Ingots (500mB each) into solid access port

What happens:
7 of 8 ingots are consumed, leaving reactor at 3500mB of Fuel.

What is expected:
8 ingots are consumed and reactor is 100% filled.

It's by design. Solid Access Ports loose some material while converting solid fuel to liquid (1.16+)

Wait, but inserting 1 ingot yields 500mB, for each of the 7 ingots consumed. The 8th ingot is not consumed, and left in the solid access port. If it was material conversion loss, then I'd expect all 8 ingots to be consumed, and less than 4,000mB to be within the reactor. As it stands, there is neither material loss nor does the reactor fill correctly.
