GURPS Spaceships Design Spreadsheet

The "FUEL USED" for a NEMA reactor is listed as "Hydrogen/Helium Isotopes" when according to GURPS Technomancer

Necronium is used in nuclear-enhanced mana area (NEMA) reactors, which create very high-mana areas in their cores.

Technomancer, p.43

Also, NEMA reactors seem to have "Compact" and "Unshielded" options. What magical effects do these options mean (ie. mana levels in the hull section of an "unshielded" reactor, "hellgate" events for damaged "volatile" ones)?
