Long story short, if you put too much fissionable material in one place, you’re asking for trouble. If it gets to that critical point and the chain reaction starts, it’s going to release a ton ...

A new chapter unfolds as the United States joins Israel's war against Iran. Helping to make sense of this rapidly changing ...

The Texas government's recent loss in a U.S. Supreme Court ruling may prove to be a long-term victory for the state — at ...

Israel’s bombing of the Iranian state broadcaster IRIB was also absurd. Israel claimed it was curtailing the regime’s attempt ...

The atomic energy agency could be made responsible for the impounding,storage and protection of the contributed fissionable and other materials. The ingenuity of our scientists will provide special ...

Many stars are variable. The "novae" flash into sudden brilliance and then fade back to dimness. Others wax & wane regularly every few days. In a letter to Britain's Nature ...

At first, U.S. avithorities seemed to agree that the Chinese must have used plutonium as their fissionable material. The process of separating U-235 from natural uranium requires enormous amounts ...

In general, advances in materials science and nano-fabrication are likely to boost us over 50% efficiency. Even more important than conversion efficiency is where we put these cells.

Violations included an issue when fissionable materials were placed in a drop-box and violated “criticality” safety posting limits, which are to help prevent fission chain-reaction accidents.

Moreover, the amount of fissionable material in both bombs was only about two pounds. In contrast, the meltdown at Chernobyl involved some two tons of material released at ground level with no ...
