About Nucleares

Nuclear Reactor Simulator puts you in the role of a power‑plant operator, letting you control a detailed reactor environment through a virtual control room, containment building, turbine hall and cooling towers. The game emphasizes realistic management of hundreds of parameters and dozens of switches, demanding careful balance of power output, coolant flow and safety systems.

An AI‑driven Operational Assistant offers procedural help, while daily objectives push you to meet energy targets, earn prestige and unlock tougher scenarios. The experience blends strategic depth with an atmospheric soundtrack and a community that shares tips and strategies.

01 / THE GUIDE

Reactor Parameter Management

Players must oversee more than 200 parameters and 150 switches spread across multiple reactor modules. Adjusting power levels, coolant flow and steam generation is essential for keeping the plant stable.

The interface lets you monitor each system in real time, allowing you to react to changes and maintain optimal performance without scripted guidance.

  • Focus on a small group of critical parameters first to avoid being overwhelmed.
  • Use the in‑game manual to understand how each switch influences overall plant behavior.

02 / THE GUIDE

AI Operational Assistant

The Operational Assistant (AO) is an AI companion that helps with ignition protocols, alarm handling and crisis management. Upgrading its skills unlocks additional functionalities.

AO can be accessed from a tablet, letting you issue commands and receive guidance while you focus on core plant operations.

  • Upgrade AO early to gain access to advanced assistance during emergencies.
  • Observe how AO suggests actions and incorporate its advice into your own decision‑making.

03 / THE GUIDE

Emergency Scenarios

Unexpected events such as equipment failures, floods and fires can arise, requiring quick decisions and precise actions to avoid catastrophic outcomes.

The game does not provide step‑by‑step tutorials for these events, encouraging players to rely on research, the AO and community knowledge.

  • Keep a reserve of coolant flow capacity to respond to sudden temperature spikes.
  • Practice routine shutdown procedures in a low‑risk setting to build confidence.

04 / THE GUIDE

Prestige & Upgrade System

Meeting daily energy production goals awards Prestige and Experience Points. These points can be spent on upgrades, fuel blocks, protective gear and radioactive waste cleanup.

Leveling up unlocks more challenging scenarios, expanding the range of tasks you must manage.

  • Prioritize upgrades that improve safety margins before those that boost output.
  • Track your Prestige spending to ensure you have resources for essential waste cleanup.

05 / THE GUIDE

Advanced Reactor Mechanics

The core features nine fuel blocks, 72 control rods and sophisticated safety systems. A chemical module adds boric acid dosing, ion exchange filtration and pH management.

Balancing thermal output, steam generation and coolant flow is crucial to prevent system failures and maintain efficient energy production.

  • Monitor pH levels alongside coolant temperature for early signs of imbalance.
  • Compare the effects of different control‑rod configurations to find the most stable setup.
