50 Megaton Tsar Bomba Declassified • Ivan RDS-220 Hydrogen Bomb
The Soviet RDS-220 hydrogen bomb (code name Ivan or Vanya), also known as Tsar Bomba (Russian: Царь-бо́мба, tr. Tsar'-bómba, IPA: [t͡sarʲ ˈbombə], lit. 'Tsar bomb'), was the most powerful nuclear weapon ever created and tested. Tested on 30 October 1961 as an experimental verification of calculation principles and multi-stage thermonuclear weapon designs, it also remains the most powerful human-made explosive ever detonated.

U.S. Ramping Up Major Renewal in Nuclear Arms
A sprawling new plant here in a former soybean field makes the mechanical guts of America’s atomic warheads. Bigger than the Pentagon, full of futuristic gear and thousands of workers, the plant, dedicated last month, modernizes the aging weapons that the United States can fire from missiles, bombers and submarines.

What It Felt Like to Test the First Submarine Nuclear Reactor
In the middle of last century, out in southern Idaho, amid the sagebrush and the steppes, the Navy kept a secret site. In that place—dry and arid, far from the sea and very much unlike it—scientists and engineers simulated a nuclear-powered submarine.

How Nuclear Explosions Were Used to Shape the Environment
The Soviet Union had successfully used underground nuclear explosions to snuff out fires at out-of-control natural-gas wells four times in the 60s and 70s. This was just one part of a large Soviet program to use nuclear explosions for a variety peaceful ends; the U.S. had a similar yet smaller program.

Fusion Breakthrough? We'll Build Compact Reactor in a Year: Lockheed
Lockheed Martin Corp said Wednesday that it had made a technological breakthrough in developing a power source based on nuclear fusion, and the first reactors, small enough to fit on the back of a truck, could be ready for use in a decade. Tom McGuire, who heads the project, said a small team had been working on fusion energy at Lockheed's secretive Skunk Works for about four years, but were going public to find potential partners in industry and government.

US Researches claim that North Korea could have as many as 100 nuclear weapons by 2020
North Korea appears poised to expand its nuclear program over the next five years and in a worst case scenario could possess 100 atomic arms by 2020, US researchers warned today. And cutting-edge European companies could be unwittingly contributing to Pyongyang's suspect nuclear program with their equipment diverted to the isolated country via China, they said. Unveiling the first results of what will be a 15-month study, Joel Wit, senior fellow at the US-Korea...

Nuclear fusion, the clean power that will take decades to master
Why don't we have nuclear fusion power yet? Because it involves taming plasmas at temperatures far hotter than the Sun's core. But the good news is that physicists are slowly but surely figuring out how.

Questioning the case for new nuclear weapons
Recent developments—Russian aggression in Ukraine, China’s expanding territorial claims, and the need to modernize the US nuclear arsenal—have caused scholars to revisit a labyrinthine world of nuclear strategy largely neglected since the end of the Cold War. But this new wave of theory has resurrected some dubious arguments. In recent months, a number of strategists have argued that the United States needs to develop a new generation of low-yield nuclear warheads to deter its adversaries...
