This part pack is designed to provide some new nuclear thermal rockets for your spaceship-building pleasure. There are four new engines, two in the 2.5m size class and two in the 1.25m size class. They are fuelled with LiquidHydrogen, and in some cases can use Oxidizer to boost their thrust at the cost of specific impulse. Liquid Hydrogen is less dense than liquid fuel, so for the same Delta-V, you will need more tank volume.
To store your liquid hydrogen fuels, I've provided ModuleManager/InterstellarFuelSwitch configs that allow you to change the contents of stock tanks between LF/O, LH2/O, LF, O and LH2. These should work with most mod tanks, but no promises. However, Liquid Hydrogen is very temperamental and without the proper storage it will slowly evaporate ("boil off"). Therefore, I provide special cryogenic tanks bundled with the mod, that use a small amount of Electric Charge to stop the evaporation.
This mod is designed to synergize well with Cryogenic Engines 0.2.0+, and with the various Near Future Technologies mods I make.

This causes boiloff to produce that resource with the specified ratio and flow mode. See Config Documentation section * Added the optional ability to specify boiloff as dependent on solar/planetary radiation input. See Config Documentation section

NFE integration patch upgrades Eel now correctly includes a passive radiator in NFE mode Fixed several missing part fields in configs (improves behaviour) Reworked exhaust cooling to not use radiator system, so normal radiators can cool engine parts (reduces explosions when entering timewarp after using an engine) Exhaust cooling is now more forgiving and takes ~10s to taper off after engine shutdown Reduced core -> part energy transfer to 0.1% from between 10-1% (reduces explosions in timewarp) CryoTanks 0.4.5 Added Russian translation from vladmir_v Fixed a typo in the version file Fixed 5m tanks throwing a B9PartSwitch warning on placement in the VAB Fixed 3.75m tanks having collider issues Adjusted the position of the nodes for the compact variants of 3.75m tanks Fixed low cost of 5m hydrogen tanks Fixed slightly off cost of 10m hydrogen tank
