Restarting the reactor — spoilers

Repair and fuel the plant, maintain cooling and carry its output through transformers to a building panel.

Spoiler boundary and prerequisites

This guide reveals reactor requirements and campaign completion steps. Bring radiation detection for the hall, treatment supplies, Electrical 3, two circuit boards, four insulated wire, one electric motor, two steel plates, fuel rods and a cooling source. Revision-9+ generation supplies plant reactor blocks; old worlds do not gain them simply through a JAR update.

Bring the plant online

  1. Clear the plant. It seeds eight infected once on first approach. The clear detector needs the relevant interior chunks loaded with no living infected inside.
  2. Repair the console: Electrical 3 and the listed parts; a resumable 60-real-second action consumes them at successful completion.
  3. Load the fuel port: four rods make one core set, with up to eight stored. A default set lasts ten survival days of operation.
  4. Provide cooling: at least three water source blocks within four blocks of the output intake, or a supported nearby pump/tank with at least one litre within six blocks.
  5. Start from the console. Default output is 2,000 energy/s. Loss of cooling triggers a safe shutdown and alarm; there is no meltdown. Fuel exhaustion stops operation.
  6. Link a transformer to the output and feed a building panel. Transformer rules still apply; reconnect the first transformer if the campaign needs to observe a line built before startup.

The useful end state is a running, cooled reactor supplying a transformer chain and a powered building panel. If it stops, check cooling, fuel and the line instead of assuming the repair completed every later requirement.

Campaign detection

QUEST-013 follows clear → repair → fuel → online → transformer → panel. It remembers certain valid reactor facts, allowing some earlier work to satisfy later checks. This exception does not make every other campaign objective retroactive. Its reward is 60 supply tokens and Electrical 500 XP with the reactor outcome, subject to eligibility.

Party choices and detailed chains belong in the campaign reference. No plant restart was performed for this wiki.
