Accelerating experimental nuclear physics with AI
The U.S. Department of Energy has funded a project to assist “the design of the ePIC detector at the future Electron-Ion Collider — a $2 billion state-of-the-art machine which will begin operations early in the next decade…and is expected to push the frontier of physics, develop new technologies and knowledge and accelerate advances in areas such as…national security.”

If there were no strong nuclear force binding atomic particles together, matter as we know it would not exist. However, there are still several unresolved questions in the study of this fundamental interaction.
What’s Impacting Assurance in the U.S. Nuclear Stockpile?
“In justification of what could be $2.5 billion in spending for new test equipment and construction, NNSA said in the fiscal 2024 budget justification material, “Current diagnostics mostly confine [test] studies to early-implosion dynamic behavior [of plutonium], while the “new test beds will enable integral tests on late-stage implosion [of plutonium].”
“To meet the current information gap in subcritical experimenting, NNSA has turned to measurement devices known as Scorpius and Zeus to determine what happens when the tiny bit of plutonium reaches high pressure and density, during the late stages of implosion.”
OPINION BY Walter Pincus, THE CIPHER BRIEF | September 12, 2023 thecipherbrief.com
The goal for having Scorpius and Zeus active and operating to clear up today’s gap is 2030. It would create an international uproar if one or both failed and the U.S. had to revive underground testing for assurance that all nuclear weapons in its stockpile were still reliable and performing as designed.
It would also mean the U.S. would be violating the CTBT.
How the ‘nuclear football’ remains a potent symbol of the unthinkable
Former military aide Buzz Patterson, who handled the football during the Clinton Administration, “recalled grappling over how he would refuse the president’s command to launch nuclear weapons if he believed they were not of sound mind and body.”
“‘And I told myself internally many times ‘If I think he’s coming across as nuts, I don’t think I can participate in this, and so that’s how I rationalized it to myself, and I think a lot of the other aides thought the same kind of thing.””

The nuclear threat has been dormant in the public’s mind since the end the Cold War. But renewed attention due to the wild success of the film “Oppenheimer’’ and rising tensions with Russia and China has brought the so-called nuclear football, the activation device for the U.S. arsenal, back into view.
The sighting of a military aide handling the football, closely following President Joe Biden as he exited a meeting with the United Kingdom’s prime minister on July 10, the day before the NATO summit during which the war in Ukraine was discussed, heightened already building tensions between NATO members and Russia.
Russia and the United States respectively lead the nuclear weapons race, both far ahead of the seven other countries that also have nuclear weapons, according to data obtained from the World Population Review.
Return of US nuclear weapons to UK would be an escalation, says Russia
Moscow says it would respond with ‘countermeasures’, after US air force budget item hinted at possible move
Julian Borger and Andrew Roth THE GUARDIAN | September 5, 2023 theguardian.com
The Russian foreign ministry has said Moscow will view any move to return US nuclear weapons to the UK as an escalation and will respond with “countermeasures” for its own security.
The foreign ministry spokesperson Maria Zakharova was responding to a report last week about an item in the 2024 US air force budget for building a dormitory at RAF Lakenheath in Suffolk for personnel on a “potential surety mission” – military jargon for nuclear safety and security. It raised the prospect of the return of US nuclear weapons to British soil for the first time in more than 15 years.
“If this step is ever made, we will view it as escalation, as a step toward escalation that would take things to a direction that is quite opposite to addressing the pressing issue of pulling all nuclear weapons out of European countries,” Zakharova said.
Nod to US? Iran’s overall enriched uranium stockpile down
Uranium enriched at 60% purity is just a short, technical step away from weapons-grade levels of 90%.
Mallika Soni, HINDUSTAN TIMES | September 4, 2023 hindustantimes.com
The UN nuclear watchdog said that Iran‘s estimated stockpile of enriched uranium was down compared to May but it was still more than 18 times the limit set in the 2015 accord. According to a confidential International Atomic Energy Agency (IAEA) report, Iran’s total enriched uranium stockpile was estimated at 3,795.5 kilograms (8,367.7 pounds) as of August 19, down by 949 kilograms from May, news agency AFP reported. The limit in the 2015 deal was set at 202.8 kilograms. Uranium enriched at 60% purity is just a short, technical step away from weapons-grade levels of 90%.

Trinity: 75 Years Later
On the 75th anniversary of the world’s first nuclear weapons explosion: The Trinity test near Alamogordo in 1945, KSFR News Director Tom Trowbridge spoke with a longtime New Mexico journalist about the anniversary.
“In Our Hands” – The academy award nominated film documenting the largest protest in US history, calling on the government to end the nuclear arms race.
Robert Richter’s IN OUR HANDS is about a magical day, June 12, 1982, when one million people took to the streets of New York to peacefully protest for an end to the nuclear arms race. It remains the largest single peace demonstration in US history.
