However, there is a key difference between atomic weapons and thermonuclear weapons, such as the H-Bomb, because the latter uses nuclear fusion in addition to fission reactions.

The idea wasn’t totally out there, believe it or not. The nuclear reactor would use uranium fission to generate power, a concept-turned-reality by the U.S. Navy. The first nuclear-powered ...

To clarify, this is not a thermonuclear bomb (which uses nuclear fusion). Traditional hydrogen bombs work through nuclear fusion, a process where atomic nuclei combine under intense pressure to ...

Gerald Frankel receives funding from ONR, DOE. Around the U.S., about 90,000 tons of nuclear waste is stored at over 100 sites in 39 states, in a range of different structures and containers. For ...

Deep Fission Inc. (Deep Fission), the pioneering nuclear energy startup revolutionizing the industry by placing reactors a mile underground, and Deep Isolation, a leader in deep borehole nuclear ...

Conventional nuclear power plants usually consist of more than one reactor, each having a generating capacity of 1,000 megawatts or so. The Palo Verde plant in Arizona has a 3,300 MW capacity.

In nuclear fission, atoms such as U-235 or Pu-239 split when a neutron hits them, releasing energy in the form of heat (along with more neutrons that can continue the chain reaction).

The Washington-based nuclear fusion startup just landed a whopping $425 million in a series F round of funding that CFO Pragav Jain says is expected to fund the company through the targeted 2028 ...

The Deep Fission reactor is based on the time-tested (67 years) traditional technology of the pressurized water reactor (PWR), the most common type of nuclear reactor around the world. even the same ...
