Build:Auxiliary Power Systems
7.4 Auxiliary Power
Cost: 3 SUs per additional fusion reactor (or 5 SUs per additional fission reactor)
Available: 2033 (fission for pre-2033)
Power Generation: 5 Power per set
Ref: Spacedock, pp 40-41
In addition to the fusion reactors which form the impulse engines, most ships carry another set of reactors simply to generate power. Each additional fusion reactor occupies 3 SUs. The crew holds auxiliary power in reserve for use in emergency or crisis situations, rather than using it at all times. Most ships have at least one auxiliary power generator for every 4 points of Size. Before 2033, fission reactors were used.
A crew can use one of a ship’s auxiliary power reactors to replace damaged or spent reactors in the impulse engines. This takes an hour and requires a Routine (4) Systems Engineering (Power Systems) or Propulsion Engineering (Impulse) Test.
