According to the Associated Press, a recent study has revealed that three quarters of America's nuclear reactors have leaked radioactive tritium from buried pipes that transport water for the cooling of reactor vessels. This tritium could in turn find its way into the groundwater. While industry officials do reportedly check these pipes for leaks, they can only do so in either indirect or costly, labor-intensive manners. Now, however, researchers from MIT are developing tiny, spherical swimming robots that could check on the pipes directly, relaying their findings in real time.
