Big Ideas Lab podcast takes on the science of scale-up

Rechargeable lithium batteries trace back to 1972, but they wouldn’t reach consumer products until 1991. Solar photovoltaic cells existed in the 1950s, long before solar panels appeared on rooftops. And the MRI was demonstrated in the 1970s, years before the machines became hospital staples. In each case, the core scientific principles had been proven. The difficult part…

TRi-structural ISOtropic (TRISO) particle fuel is fully encapsulated by layers of carbon- and ceramic-based materials that prevent the release of radioactive fission products. Each particle (roughly the size of a poppy seed) acts as its own containment system and is more resistant to neutron irradiation, corrosion, oxidation, and high temperatures than traditional reactor fuels.

LLNL partners with industry to advance next-generation reactor fuel

Small, modular nuclear fission reactors are emerging as a resilient energy option, offering a scalable, cost-effective path to reliable power for remote or infrastructure-limited locations. However, these advanced reactor facilities typically run hotter and longer than conventional light water reactors, so they will require a new type of nuclear fuel tough enough to…

A simulation from the study shows density (top) and temperature (bottom) just before the time when fusion reactions peak in an asymmetric implosion. The hottest point coincides with the densest point of fuel, illustrating the direct ignition of a dense jet of fuel driven by asymmetry. The image was recently selected for the cover of Physics of Plasmas.

Livermore research shows how fusion reactions can survive flaws — up to a point

Researchers at Lawrence Livermore National Laboratory (LLNL) have found that implosions designed for inertial fusion energy (IFE) can tolerate significant imperfections before performance abruptly declines, a finding that could inform the design of fuel targets for future fusion power plants. The findings were detailed in a paper titled “Robustness of inertial fusion…

Isotope probing shows soil is packed with dormant viruses lying in wait

A single gram of soil contains between 10 million and 1 billion viruses. Most of those viruses do not infect plants, animals or people — but they do target bacteria and other microbes. Because of their influence on microbial communities, viruses can affect nutrient cycling and soil health. Understanding how they behave is therefore crucial for supporting agriculture, food…

In an inertial confinement experiment on the National Ignition Facility, the lasers converge at tiny entrance holes at the top and bottom of the hohlraum. The intersection of the lasers enables crossed-beam energy transfer, an important factor in maintaining symmetry of implosions.

Research sheds new light on laser polarization effects in NIF experiments

Experiments at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) require breathtaking precision. Each of the 192 lasers is focused to a width of a few millimeters to enter a 3-millimeter hole at the top or bottom of a 2-centimeter gold canister known as a hohlraum. As they enter, the beams intersect in plasma and transfer power, a process known as…
