Kerbal Atomics

A mod pack for Kerbal Space Program, focused on delivering additional high quality nuclear thermal engine parts.

Features

This mod features several new nuclear thermal engines that expand the range of nuclear propulsion options available. All these engines use a new resource, Liquid Hydrogen. Engines are provided in almost all size classes

  • Bimodal Engines: Can switch to using both LH2 and Oxidizer for a thrust boost at the cost of efficiency. Available in a 1.25m size.
  • Trimodal Engines: Like a bimodal engine, but also generates a nice amount of energy when idle. In 0.625m, 1.25m and 2.5m sizes.
  • Gas Core Engines: Advanced nuclear designs in closed-cyle and open-cycle versions. The open-cycle engine is horrifically overpowered, but cannot be refueled.
  • Nuclear Aerospikes: For launch operations, a solid core and a gas core aerospike. Compromises, much like the regular stock aerospike

In addition, my CryoTanks mod is also bundled to provide fuel handling for Liquid Hydrogen.

  • Fuel Switching: A set of patches provide fuel-switching features for most basic LF and LF/O tanks
  • Orbital Fuel Tanks: A set of fuel tanks specially designed to contain LH2

For more information, check out the CryoTanks readme.

Dependencies

Required

These components are required for the mod to function and are bundled as part of any download:

Installation

To install, place the GameData folder inside your Kerbal Space Program folder. If asked to overwrite files, please do so.

NOTE: Do NOT rename or move folders within the GameData folder - this mod uses absolute paths to assets and will break if this happens.

Optional Patches

Some extra patches are bundled that you can use to tweak your installation. To install them, drop the correct folder from the Extras folder into your KSP GameData Folder

  • KerbalAtomicsNTRModSupport: Supports other NTR mods by converting their NTRs to use LiquidHydrogen
  • KerbalAtomicsNTRsUseLF: Converts engines to use LF instead of LH2 at the cost of a big chunk of Isp
  • NearFutureElectricalNTRs: When installed with Near Future Electrical, unlocks new functionality for nuclear engine operation. See more below

Near Future Electrical Integration

For those desiring more integration with NF Electrical, such as power-producing reactors, the NearFutureElectricalNTRs patch can be installed. This increases reactor realism but also makes them much more complex to operate.

  • Reactor Integration: NTRs have a reactor that must be activated and heated up before they can be used for thrust. Operating the engine without it on will produce no thrust and just waste propellant.
  • Reactor Cooling: Like NFE power reactors, the NTR reactor has to be cooled while in use. Running propellant through the engine will remove 100% of generated heat, but if you want to leave the reactor on when not thrusting, you will need to add radiators.
  • Power Generation: Trimodal NTRs can dedicate a bit of their capacity to produce power. The reactor must be on to do this, 1% reactor throttle is enough to generate full power/
  • Fuel Consumption: Running the reactor will use up fuel, included in the engines. The engines can be refueled in the same was as the ones in NFE. Note that in this mode, the Emancipator engine can indeed be refueled.
  • Engine Heat Generation: When this patch is installed, the "overheat" of the NTRs is disabled

External Mod Compatibility

This mod includes compatibility patches for the following mods:

  • KSP-AVC: Provides version checking
  • Community Tech Tree: Provides an expanded, community-sourced technology tree for modders to use

Contributing

I certainly accept pull requests. Please target all such things to the dev branch though!
