Overview#
Nuclear Control 2 is the definitive utility mod for players utilizing IndustrialCraft 2's nuclear power systems. The mod's primary purpose is to prevent catastrophic reactor meltdowns by providing real-time data on heat levels, energy output, and fuel status. It introduces a suite of tools including thermometers, remote sensors, information panels, and high-decibel alarms that can be configured to trigger redstone signals when specific safety thresholds are met.
Beyond reactor safety, the mod extends its functionality to monitor energy storage units (like MFEs and MFSUs) and fluid tanks, making it an essential component for complex industrial automation. It allows players to centralize data from across their base into a single control room using wireless transmission and modular display panels.
Monitoring Blocks#
Monitoring blocks are the primary interface between your machinery and the Nuclear Control system. They detect physical states and convert them into data or redstone signals.
Thermal Monitor
The Thermal Monitor is a safety block placed directly adjacent to a Nuclear Reactor. It allows players to set a specific temperature threshold. If the reactor's heat exceeds this limit, the monitor emits a redstone signal. This is typically used to shut down the reactor automatically before it reaches its melting point.
- GUI: Right-clicking opens a menu to set the heat limit (e.g., 500, 1000, 8000).
- Placement: Must be touching a Reactor Block or Reactor Chamber.
Range Trigger
The Range Trigger is a versatile automation block. It accepts a Sensor Card (Reactor, Energy, or Liquid) and allows the player to define a 'Start' and 'End' value. When the value on the card falls within or outside this range, the block emits a redstone signal. This is ideal for turning on backup generators when energy levels are low or stopping pumps when tanks are full.
Remote Sensor Station
This block acts as a wireless transmitter. By placing a Sensor Card inside the station, the data from the linked machine is broadcast to any Industrial Information Panel within range. This eliminates the need for long cable runs between your reactor and your control room.
Display and Alarm Blocks#
These blocks are used to visualize data and provide audible warnings to the player.
Industrial Information Panel
The core of the display system. This block displays information from a Sensor Card placed in its internal slot. It can show reactor heat, EU storage levels, or custom text.
- Expansion: Can be expanded into a larger screen using Panel Extenders placed adjacent to it.
- Customization: Supports Color Upgrades to change text color and Range Upgrades to increase wireless pickup distance.
Panel Extender
Extenders do not have a GUI. When placed next to an Industrial Information Panel, they expand the visual display area, allowing for larger text and more data lines to be visible simultaneously.
Howler Alarm
A high-volume audio warning device. When powered by a redstone signal, it emits a loud siren.
- Sound Selection: Players can choose from several alarm sounds in the GUI.
- Range: The sound can be heard from a significant distance, ensuring players are warned even if they are in a different part of their base.
Industrial Alarm
Similar to the Howler Alarm, but includes a visual component. The block features a rotating red light that activates alongside the siren, providing a visual cue in noisy environments.
Sensor Kits and Cards#
Sensor Kits are one-time use items used to link a machine to a Sensor Card. Once a kit is used on a block, it yields a card encoded with that block's coordinates.
| Kit Name | Target Block | Resulting Card |
|---|---|---|
| Remote Sensor Kit | Nuclear Reactor / Chamber | Reactor Sensor Card |
| Energy Sensor Kit | MFE, MFSU, CESU, BatBox | Energy Sensor Card |
| Liquid Sensor Kit | IC2 Tanks, Railcraft Tanks | Liquid Sensor Card |
| Energy Array Sensor Kit | Multiple Energy Blocks | Energy Array Card |
Card Types
- Reactor Sensor Card: Displays current heat, maximum heat, and the reactor's On/Off status.
- Energy Sensor Card: Displays current EU stored, maximum capacity, and the fill percentage.
- Liquid Sensor Card: Displays the amount of fluid (mB) and the type of fluid in a tank.
- Text Card: A manual card where players can type custom messages to appear on Information Panels.
- Time Card: Displays the current Minecraft world time (Digital or Analog format).
- Counter Sensor Card: Used with the Average Counter block to track EU/tick flow over time.
Tools and Upgrades#
Thermometers
- Thermometer: A handheld tool used to check the heat of a reactor. It must be used directly on the reactor.
- Digital Thermometer: An advanced version that provides the exact numerical heat value and the reactor's melting point. It can also be used to configure Thermal Monitors by Shift-Right-Clicking them.
Upgrades
Upgrades are placed in the upgrade slots of Information Panels or Remote Sensor Stations.
- Range Upgrade: Increases the distance (in blocks) that a panel can communicate with a Remote Sensor Station or a linked machine.
- Color Upgrade: Allows the player to change the background and text color of an Industrial Information Panel via a color picker GUI.
Mechanics and Automation#
The Monitoring Loop
To set up a basic automated safety system, follow these steps:
- Place a Thermal Monitor against your Nuclear Reactor.
- Set the threshold to a safe level (e.g., 2000 degrees).
- Run a redstone wire from the Thermal Monitor to the reactor itself (or a toggle latch). When the heat hits 2000, the monitor will emit redstone, turning the reactor off.
- Use a Remote Sensor Kit on the reactor to get a Reactor Sensor Card.
- Place an Industrial Information Panel in your control room and insert the card.
- If the panel is too far away, place the card in a Remote Sensor Station near the reactor and put Range Upgrades in the panel.
Energy Array Monitoring
The Energy Array Sensor Kit allows for the monitoring of up to 6 energy storage blocks simultaneously. By clicking multiple blocks with the kit before crafting the card, the Information Panel will display the aggregate energy of the entire power bank.
Crafting Recipes#
The following table lists the standard recipes for core components using IndustrialCraft 2 Experimental materials.
| Result | Ingredients |

Note: Recipes may vary if other mods like GregTech are installed, as Nuclear Control 2 supports dynamic recipe integration.
Mobs and World Generation#
Nuclear Control 2 is a technical utility mod and does not add any new mobs, creatures, biomes, or dimensions to the game. It focuses entirely on block-based machinery and item-based tools to enhance the IndustrialCraft 2 experience. All functionality is contained within the added blocks and their interactions with existing IC2 nuclear and energy systems.
