In fusion experiments, understanding the behavior of the plasma, especially the ion temperature and rotation velocity, is essential. These two parameters play a critical role in the stability and performance of the plasma, making them vital for advancing fusion technology. However, quickly and accurately measuring these values has been a major technical challenge in operating fusion reactors at optimal levels.

Fusion researchers are increasingly turning to the element tungsten when looking for an ideal material for components that will directly face the plasma inside fusion reactors known as tokamaks and stellarators. But under the intense heat of fusion plasma, tungsten atoms from the wall can sputter off and enter the plasma. Too much tungsten in the plasma would substantially cool it, which would make sustaining fusion reactions very challenging.

Researchers have captured the signal of neutrinos from a nuclear reactor using a water-filled neutrino detector, a first for such a device.

One of the key features of the eVinci microreactor is its impressive versatility. It will have the capability to generate five megawatts of electricity, produce over 13 megawatts of high-temperature heat, or operate in combined heat and power mode, according to the Saskatchewan Research Council.

To put this in perspective, the Nuclear Regulatory Commission reported in 2012 that a single megawatt of capacity from a conventional power plant can meet the energy needs of 400 to 900 homes in a year.

The group’s detector design exploits Cherenkov radiation, a phenomenon in which radiation is emitted when charged particles moving faster than light pass through a particular medium, akin to sonic booms when crossing the sound barrier. This is also responsible for nuclear reactors’ eerie blue glow and has been used to detect neutrinos in astrophysics laboratories.

The researchers proposed to assemble their device in northeast England and detect antineutrinos from reactors from all over the U.K. as well as in northern France.

One issue, however, is that antineutrinos from the upper atmosphere and space can muddle the signal, especially as very distant reactors yield exceedingly small signals—sometimes on the order of a single antineutrino per day.

Small, easily transportable nukes could power our data driven future.

On September 29, 1901 Enrico Fermi ForMemRS was born.

On May 11, 1974, National Accelerator Laboratory was given a new name: Fermi National Accelerator Laboratory. The eponym honors famed Italian physicist Enrico Fermi, whose accomplishments in both theoretical and experimental physics place him among the greatest scientists of the 20th century.

Many visitors to Fermilab reasonably conclude from its name that Enrico Fermi worked at the laboratory, but he never did. In fact, he died in 1954, years before scientists even officially recommended the construction of a U.S. accelerator laboratory in 1963.

Like atoms coming together to release their power, fusion researchers worldwide are joining forces to solve the world’s energy crisis. Harnessing the power of fusing plasma as a reliable energy source for the power grid is no easy task, requiring global contributions.

What just happened? Researchers have successfully deployed a fully autonomous robot to inspect the inside of a nuclear fusion reactor. This achievement – the first of its kind – took place over 35 days as part of trials at the UK Atomic Energy Authority’s Joint European Torus facility.

JET was one of the world’s largest and most powerful operational fusion reactors until it was recently shut down. Meanwhile, the robotic star of the show was, of course, the four-legged Spot robot from Boston Dynamics, souped up with “localization and mission autonomy solutions” from the Oxford Robotics Institute (ORI) and “inspection payload” from UKAEA.

Spot roamed JET’s environment twice daily, using sensors to map the facility layout, monitor conditions, steer around obstacles and personnel, and collect vital data. These inspection duties normally require human operators to control the robot remotely.
