3D printing will also help nuclear engineers get a better picture of what is happening inside a core once the reactor is up and running. In a conventional reactor, a core’s behavior has to be ...

Understanding the physical behavior inside an operating nuclear reactor can be done only with simulations on a supercomputer due to the high-pressure, high-temperature, and radioactive environment ...

The Radiant Nuclear townhall Monday night in Bar Nunn was geared toward addressing Natrona County residents' concerns about ...

Ratu founded Wellington-based OpenStar Technologies in 2021 with the goal of developing an efficient nuclear fusion reactor.

Step inside a nuclear reactor and witness one of the most bizarre phenomena – radioactive fluorescence. In this video, we explore the strange and visually captivating glow that occurs inside a ...

MIT’s research reactor was built in the 1950s, and its purpose has shifted over the decades. At various points, it’s been used to study everything from nuclear physics to medical therapies ...

The approach to cooling is very simple: push water past the nuclear core and carry the heat somewhere else. The chain reaction that actually runs the reactor can be shut off in a matter of seconds.

The radiation level in the containment vessel of reactor 2 at the crippled Fukushima No. 1 power plant has reached a maximum of 530 sieverts per hour, the highest since the triple core meltdown in ...

The 56% who support nuclear energy didn’t say anything about a reactor going up down the street. “Humans are not always great at assessing risk,” says Kochunas.
