Waste solution

With the disposal of nuclear waste high on the political agenda, a group of physicists claims to have discovered a technique that could make it harmless on timescales of just a few tens of years.
Professor Claus Rolfs, leader of the group at
The nuclear waste would be embedded in a metal and cooled to ultra-low temperatures. This speeds up the rate of decay of the radioactive material potentially cutting its half life by a factor of 100 or more.
Professor Rolfs said, ‘We are currently investigating radium-226, a hazardous component of spent nuclear fuel with a half-life of 1600 years. I calculate that using this technique could reduce the half-life to 100 years. At best, I have calculated that it could be reduced to as little as two years.‘
