1352:07.10 Unit’s CPU provides signal to low explosive to detonate. Low explosives detonate. Flame path to high explosives operational. High explosives begin detonation.
1352.07.11 High explosives compress two halves of plutonium sphere. Plutonium becomes completely spherical. Plutonium neutron level cascades to runaway. Nuclear detonation expected in approximately—
The fission bomb explosion of Gigantskiy unit one formed a plasma that expanded from the close confines of the weapon’s plutonium compartment into the heavy water compartment. Up to that point, the nuclear explosion was generating energy from the elimination of mass from the heavy plutonium nuclei splitting into two lighter atoms, with the product atoms weighing less than the original plutonium. The missing mass was converted to energy in the form of explosive heat. As the plasma blew outward, it enveloped the heavy water cans, the heavy water able to fuse together to form helium atoms, and again, the resulting products were lighter than the heavy water at the start of the reaction, the difference in mass converted to pure energy, and the fission bomb became a fusion bomb, also known as a hydrogen bomb.
The plasma expanded outward from the central point and quickly devoured the weapon. Fifty meters to the east, a monolithic ice wall extended from the sea floor to an ice ridge range above. The plasma expanded and reached out to the wall. The surface of the ice wall began to vaporize and become a plasma itself, the electrons of the water molecules flying off into space.
One second after detonation, a half mile hole was blown into the ice wall and the ice overhead opened up into open water, the explosion blowing high into the atmosphere. On the other side of the explosion from the ice wall, the detonation caused a pressure wave to extend outward, at first spherically, but when it hit the shallow bottom and the ice overhead, it reinforced itself into a solid wave spreading out cylindrically.
Six-and-a-half nautical miles from the torpedo explosion, the shock wave hit the Russian submarine
The shock wave was violent and merciless to both submarines.
One moment, Captain First Rank Georgy Alexeyev was strapped into his seat at the port side of
The next moment the central command post was hit by a high speed freight train and the compartment was thrown to the left until the deck became a wall, and Alexeyev lost consciousness.
