KN-3 reactor
Encyclopedia
The KN-3 reactor is the nuclear fission
reactor
used in pairs to power the Kirov-class battlecruisers
. The reactor was also intended to be used on the Ulyanovsk class
of supercarrier
s. It is a pressurized water reactor
(PWR), using enriched
uranium-235
fuel to produce 300 MW of power.
Nuclear fission
In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts , often producing free neutrons and photons , and releasing a tremendous amount of energy...

Nuclear reactor
A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Most commonly they are used for generating electricity and for the propulsion of ships. Usually heat from nuclear fission is passed to a working fluid , which runs through turbines that power either ship's...

Enriched uranium
Enriched uranium is a kind of uranium in which the percent composition of uranium-235 has been increased through the process of isotope separation. Natural uranium is 99.284% 238U isotope, with 235U only constituting about 0.711% of its weight...
