Missouri Elementary School Contaminated With Radioactive Waste

Posted by in categories: military, nuclear energy

Sign up for the Morning Brief email newsletter to get weekday updates from The Weather Channel and our meteorologists.

A new report shows there is a significant amount of radioactive contamination inside an elementary school in suburban St. Louis, near where waste was dumped from a World War II nuclear weapons factory.

The U.S. Army Corps of Engineers has been working for years to clean up toxic waste near the St. Louis Lambert International Airport, where byproducts from the weapons manufacturing were dumped near a waterway called Coldwater Creek.

Taking Control of Fusion Reactor Instabilities

Posted by in categories: nuclear energy, particle physics

A mechanism for preventing destructive instabilities in magnetically confined plasmas provides a new way for scientists to operate future nuclear-fusion reactors.

All magnetically confined plasmas naturally develop instabilities, regions where small perturbations grow rapidly [1]. Scientists have been looking for ways to prevent instabilities in a tokamak—a leading candidate for a fusion reactor—because the instabilities can cause substantial damage to the tokamak’s walls. Now Georg Harrer at the Vienna University of Technology and his colleagues have shown how these destructive instabilities can be avoided by adjusting the properties of the plasma and its confining magnetic field [2]. The researchers’ findings offer a fresh approach to running future fusion reactors.

A tokamak uses a powerful magnetic field to confine fusion fuel in the form of a plasma (a highly ionized gas) that is shaped like a ring donut. Instabilities that originate at the plasma edge (the “glaze” of the donut) are called edge-localized modes (ELMs) [3]. ELMs transport heat and particles along magnetic-field lines, moving them from the well-confined plasma core (the “filling” of the donut) to the divertor—a region of the tokamak’s walls. ELMs come in various sizes and frequencies (repetition rates). Their size, expressed as a percentage of the energy stored in the plasma core, strongly influences how much heat and how many particles will be deposited by each ELM in the divertor.

Ukraine nuclear plant has lost final external power link, UN watchdog says

Posted by in category: nuclear energy

BERLIN (AP) — Ukraine’s Zaporizhzhia nuclear power plant, the biggest in Europe, has lost its last remaining external power source as a result of renewed shelling and is now relying on emergency diesel generators, the U.N. nuclear watchdog said Saturday.

The International Atomic Energy Agency said the plant’s link to a 750-kilovolt line was cut at around 1 a.m. Saturday. It cited official information from Ukraine as well as reports from IAEA experts at the site, which is held by Russian forces.

All six reactors at the plant are shut down but they still require electricity for cooling and other safety functions. Plant engineers have begun work to repair the damaged power line and the plant’s generators — not all of which are currently being used — each have sufficient fuel for at least 10 days, the IAEA said.

Russian nuclear submarine armed with ‘doomsday’ weapon disappears from Arctic harbor: report

Posted by in categories: drones, existential risks, military, nuclear energy

Is this a sign of nuclear escalation?


A top-of-the-line Russian nuclear-powered submarine has gone missing from its harbor in the Arctic along with its rumored “doomsday weapon,” according to multiple reports.

NATO has reportedly warned members that Russia’s Belgorod submarine no longer appeared to be operating out of its White Sea base, where it has been active since July. Officials warned that Russia may plan to test Belgorod’s “Poseidon” weapons system, a drone equipped with a nuclear bomb that Russia has claimed is capable of creating a “radioactive tsunami,” according to Italian media.
