In a dramatic escalation, Israel has struck Iran’s Arak heavy water nuclear reactor, using 40 fighter jets in a precision ...

How did Iran build a bomb, what are enriched uranium and plutonium, what role do centrifuges play, and how would the ...

Another type of uranium-plutonium fuel for fast reactors is nitride SNUP fuel, which will be used in the first innovative lead-cooled reactor BREST-OD-300, under construction in Seversk. Alexander ...

Ukraine has enough plutonium to construct hundreds of nuclear warheads for rudimentary bombs akin to the first atomic weapons dropped on Japan by the US in 1945, a new report has revealed.. A ...

Ukraine could be "months away" from manufacturing a nuclear bomb capable of inflicing Nagasaki-style instruction on a Russian city if the US drops military aid, top officials have claimed.

In 2013, the Los Alamos pit facility, called PF-4, was closed for three years because of mishandling of plutonium rods that could have created a criticality accident, according to Dylan Spaulding ...

Lightbridge's metallic fuel (Image: Lightbridge) A study using a variant of Lightbridge Fuel in which uranium-zirconium alloy was substituted with an equivalent plutonium-zirconium composition found ...

So, special production reactors are used to create fissile plutonium. Once the fuel rods in a production reactor are finished, the plutonium is chemically separated from any remaining 238 U and ...

About 6 percent of the fuel in reactor No. 3 at the Fukushima Dai-ichi nuclear plant in Japan is made of a "mixed-oxide" fuel, which contains plutonium — which stays hazardous for tens of ...

North Korea has halted the nuclear reactor at its main atomic complex, probably to extract plutonium that could be used for weapons by reprocessing spent fuel rods, a South Korean news report said ...

For a start, they seem unaware that not all plutonium isotopes are the same. The plutonium involved in the CANDU waste stream is mostly Pu-240, not Pu-239 (ie., reactor grade, not weapons grade). You ...

Lightbridge plutonium disposition fuel variant consumes 5.5 times more plutonium per fuel rod than mixed-oxide (MOX) fuel. Lightbridge’s proprietary next-generation nuclear fuel technology features ...
