Nucleares Beginner Guide Nucleares Game Walkthrough Wiki

1 Read before you switch anything

Nucleares deliberately provides no step by step tutorial. It points you at an in-game manual and suggests researching how real reactor operations work, and it expects the community to fill the rest.

Fighting that design wastes hours. Twenty minutes with the manual before your first startup will save more time than any amount of experimenting, because the failure modes here are slow and expensive rather than instructive.

2 Learn the building layout

The plant is split across four named areas, and knowing which controls live where removes a large amount of early confusion.

There are also underground maintenance tunnels to explore. Walking the whole facility once, before anything is running, is time well spent.

3 Your first startup

Ignition protocols are one of the things AO explicitly helps with, and using that help on a first attempt is sensible rather than cowardly. Watch what it does, and note the order.

The physical chain runs in one direction. Reactor power heats coolant, coolant makes steam, steam drives the turbine, and the cooling towers remove what is left. When something goes wrong, tracing that chain from the reactor outward finds the cause faster than checking panels at random.

Nine fuel blocks and 72 control rods sound intimidating, but rods are the throttle. Understanding that one relationship, between rod position and reactor power, is most of what a first session needs.

4 Let AO carry the routine

The Operational Assistant covers ignition protocols, alarm systems and crisis management, and it can be upgraded to unlock advanced functionality. There is also a free AO Extra Power Pack that extends it further.

Pair that with the remote tablet, which lets you manage reactor tasks, control AO and oversee operations from anywhere in the plant. Between them, you can stop treating physical distance as a mechanic and start treating it as scenery.

The limit is worth stating plainly. AO helps you execute, not decide. It will not tell you that your chemistry is drifting or that the community demand you accepted was unwise.

5 Change one thing at a time

Because the systems are dynamic, adjusting reactor power moves coolant behaviour, which moves steam generation, which moves output. Two simultaneous changes produce a result you cannot attribute to either.

The discipline that makes this game teachable is therefore very simple: make one adjustment, wait for the plant to settle, read the numbers, and only then make the next one. Thermal systems respond slowly, and impatience reads as failure.

This is also why the game rewards note taking so heavily. A record of what you changed and what happened turns a confusing session into a reference you can reuse.

6 Failure is a bill, not an ending

Emergency scenarios include equipment failures, floods and fires, and they are meant to be responded to rather than avoided perfectly. What makes the game forgiving is where the consequences land.

Prestige Points can be spent on radioactive waste cleanup, which means a bad day becomes an expense rather than a lost save. That changes the emotional register of the whole game: mistakes are costly, not fatal.

For a beginner, the useful consequence is that you can afford to try things. A cautious operator who never learns how the plant behaves under stress is worse prepared than one who has already paid for a few cleanups.
