NUCLEAR WASTE STORAGE CONTAINERS BREAK DOWN WHEN EXPOSED TO WATER via Futurism

DAN ROBITZSKI

The U.S. government’s plan for safely storing nuclear waste just hit a serious snag: Exposure to groundwater could corrode its new storage containers, spilling radioactive materials into the Earth.

The plan, as it stands, was to trap nuclear waste in glass or ceramic and bury the horrible mixture in stainless steel containers, Science News reports. But the new groundwater study potentially sends scientists back to the drawing board as they tackle the staggering challenge of storing hazardous materials for millennia at a time.

Their findings, published last week in the journal Nature Materials, showed that a groundwater-like solution caused a chain reaction that ended up eating away at the steel container.
Imperfect Setup

It’s worth noting that a lab environment is very different from an actual underground nuclear waste dump — and bombarding a piece of steel and ceramic with saltwater creates a more extreme response than the occasional groundwater seepage is expected to in the real thing, Science Newsreports.

All the same, the team of engineers hopes to develop a new lining material that could better keep groundwater out — and radioactive waste in.
