Chernobyl Nuclear Fuel Particles Remain Stable 40 Years After Disaster
Researchers found some 8 to 50 micrometer fragments still preserve the reactor fuel’s crystal structure and may release radionuclides slowly.
- Forty years after the Chernobyl disaster, researchers found that microscopic fuel fragments remain chemically stable, preserving their original crystal structure and trapping fission products inside.
- Physicist Tobias Weissenborn stated that three types of radioactive particles escaped the Chornobyl nuclear power plant after the explosion, including fuel-like fragments and graphite fire particles formed during a ten-day moderator fire.
- Scientists at Leibniz University Hannover and Helmholtz-Zentrum Dresden-Rossendorf examined six fragments using synchrotron X-ray diffraction at the Rossendorf Beamline in Grenoble, France, rotating each through 2,000 angles.
- While the particles are more stable than assumed, they remain dangerously radioactive; Weissenborn warned that the small sample of six particles prevents researchers from defining regional health risks or lifting Chornobyl Exclusion Zone restrictions.
- Researchers are now conducting follow-up experiments on transuranium phases, which are even more radioactive leftovers from the disaster, with every discovery adding to understanding of the event's chemistry.

The Chernobyl nuclear disaster continues to leave unanswered questions four decades later. A group of scientists have examined tiny radioactive remains and discovered that some retain their original structure better than expected, although each fragment tells a different story.

Scientists have found that microparticles of nuclear fuel from the Chernobyl zone 40 years after the accident have retained their crystalline structure and are still highly radioactive.
Radioactive particles are proving to be significantly more stable than previously thought. Four decades after the 1986 nuclear disaster, researchers at
