How to Shelter from a Nuclear Explosion
There is no good place to be when a nuclear bomb goes off. Anything too close is instantly vaporized, and radiation can pose a serious health threat even at a distance. Researchers simulated an atomic bomb explosion from a typical intercontinental ballistic missile and the resulting blast wave to see how it would affect people sheltering indoors.

Was That Explosion Chemical or Nuclear?
If an underground explosion occurs anywhere in the world, there is a good chance that a seismologist can pinpoint it. However, they won’t necessarily be able to tell you what kind of explosion had occurred—whether it is chemical or nuclear in nature. New PNNL research makes it easier to differentiate between the two.

Experts: North Korea's ICBMs Pose Preemption Challenges for US
North Korea’s rapidly advancing ICBM capabilities pose a growing threat to the United States and its allies, especially as it will become increasingly difficult to destroy Pyongyang’s missiles prior to launch with preemptive strikes.

Accepting Reality: For the Foreseeable Future, Denuclearizing North Korea May Be Unattainable
For two decades now, U.S. policymakers have sought North Korean denuclearization. In the early 2000s, it appeared to be a necessary goal, because a nuclear North Korea would threaten U.S. allies, spread nuclear weapons beyond the Korean Peninsula, damage the sanctity of the nuclear taboo, and eventually threaten U.S. territory. But the enemy gets a vote, and it is now clear that for the foreseeable future, there is nothing the United States can do, short of a direct military attack, to eliminate North Korea’s nuclear weapons.

The Cold War Legacy Lurking in U.S. Groundwater
In America’s rush to build the nuclear arsenal that won the Cold War, safety was sacrificed for speed. ProPublica has cataloged cleanup efforts at the 50-plus sites where uranium was processed to fuel the nation’s nuclear arsenal. Even after regulators say cleanup is complete, polluted water and sickness are often left behind.

North Korea’s Nuclear Program Is Funded by Stolen Cryptocurrency. Could It Collapse Now That FTX Has?
Kim Jong-un’s military operation hackers have been stealing cryptocurrency to support North Korea’s nuclear and missile program for several years. But with the general downturn in the crypto market, coupled with the recent FTX collapse and myriad other pitfalls, analysts estimate North Korea has probably lost most of its crypto haul. Can we expect its nuclear weapons development to come to a halt, or slow down? It seems unlikely.

Iran Building Nuclear Weapons
Rather than a traditional nuclear weapons program, Iran threatens the world with a program ready to produce nuclear weapons “on-demand.” Its readiness program poses a difficult challenge to the international community and the International Atomic Energy Agency (IAEA). Understanding the pace of Iran building nuclear weapons matters, in particular, for designing strategies against Iran moving to construct them.

Iran Needs Only 4 Weeks to Produce Enough Material for 4 Nuclear Weapons
Due to the current size of Iran’s 60 percent, 20 percent, and 4.5 percent enriched uranium stocks, Iran can now produce enough weapon grade uranium for four nuclear weapons in one month and make enough for a fifth weapon within the following month.

How the Biden Administration Is Responding to Putin’s Threats to Go Nuclear
Russia’s use of nuclear weapons would not necessarily be considered in contravention of Article 5 of the NATO treaty, whereby an attack on one is considered an attack on all and requires collective military defense. But experts say that a case could be made that if radiation from use of a nuclear warhead were to spill over into a NATO country, this could be construed as an attack.
