Summary:

Trinity is an addon for NuclearCraft that adds various nuclear bombs to the game, as well as semi-realistic ways of crafting them.

Important notes:

Versions beginning with "1" require NuclearCraft: Overhauled and will not run with pre-overhaul NuclearCraft.
If using pre-overhaul NuclearCraft, use the latest version beginning with "0".

Features:

- ICBM integration: ICBM's nuclear missiles and explosives will trigger a Trinity nuclear explosion instead of ICBM's nuclear explosion.

- 18 different nuclear bombs made from nine different fissile isotopes.

- Two different redstone-activated conventional explosives, both of which are used to craft nuclear bombs.

- Salted bombs, which leave behind extremely high radiation levels.

- Dirty bombs, seemingly innocent looking TNT blocks with a radioactive surprise.

- Antimatter bombs: All of the explosive power of a nuclear bomb, but without the radioactivity! Currently has no crafting recipe.

- Thermonuclear bombs, multiblock bombs with varying explosion effects based on what blocks are used in their construction.

- Custom bombs (disabled by default): Four standard fission bombs and four salted fission bombs with no crafting recipe by default, meant for use in modpacks where recipes can be added via CraftTweaker

- Semi-realistic crafting recipes including subcritical isotope spheres, compression charges, and several chemical recipes.

- Bombs have tooltips indicating the size of the crater, as well as the size of the radioactive wasteland that is created around it.

- A remote detonator that can be used to detonate bombs from relatively safe distances (more than 2x the crater radius).

- Special radioactive deposits left behind after the explosion such as trinitite, and highly radioactive sand and soil from salted bombs.

- Full configurability for blast size and fallout radius.

How to build a thermonuclear bomb:

Step 1: Place down any nuclear bomb. Note that the larger the blast radius, the larger the blast radius of the thermonuclear bomb will be.

Step 2: Place a column of three thermonuclear bomb cores above the nuclear bomb. They must all be vertically aligned, so that the plutonium rods within them connect.

Step 3: Surround the thermonuclear cores with a "tamper" made of reflective, fissionable, or salting blocks. Reflective blocks are effectively inert, and only increase the explosion power by a little bit. Fissionable blocks greatly amplify the explosion. Salting blocks will absorb some of the explosion's energy, and convert it into extremely radioactive fallout.

Step 4: Link the nuclear detonator to the nuclear bomb and detonate it. If the above steps were done correctly, you should have a very large thermonuclear explosion take place.
