does not release energy rapidly, only very very slowly. Fuel Yes, bombs no
You should... like... at least watch the HBO series Chernobyl.
The reason energy is released slowly inside a reactor, is because it is specifically designed to do that - with graphite control rods (which remove neutrons from the chain reaction), and water submersion (water gets hotter and less dense, slowing reactivity).
A bomb is designed to do the literal opposite. Not 1 neutron, from each fission, causing another fission... But 1 causing 2, 2 causing 4, 4 causing 8, 8 causing 16, and so on - all within tens of nanoseconds.
The reaction inside a bomb scales exponentially, and on the most compressed time frames.
Did you know that Fusion between Hydrogen into Helium has never been proven in a..
I don't understand why this matters. In a hydrogen bomb, the fusion happens between hydrogen isotopes (THATS WHY ITS CALLED A HYDROGEN BOMB).
Deuterium (^2H) is fused with Tritiuk (^3H), and this produces 1 free neutron, a sh*tload of energy, and yes Helium-4 (but nothing is fused with it).
there's no guarantee that Fusion (the opposite of Fission) actually releases energy at all.
It obviously does produce energy, as shown above.
You take Deuterium (1 proton + 1 neutron) and fuse it with Tritium (1 proton + 2 neutrons). The resulting Helium-4 has only 2 protons and 2 neutrons.
One neutron is now free. This sustains further chain reactions. Helium-4 is also more tightly bound and stable than deuterium or tritium. The tiny amount of mass that is "lost" while forming ^4He is released as energy, because... E=MC^2.
