"Scientists discover cheap and environmentally friendly way to dispose of waste from nuclear power plants
Scientists from the University of Strathclyde collaborating with an international team from Imperial College, Rutherford Appleton Laboratory(RAL), ITU (Karlsruhe) and the University of Jena have successfully turned the radioactive isotope Iodine-129, a major waste product in the nuclear power industry, into the more friendly isotope Iodine-128 using the VULCAN Laser at RAL. This is the first time an isotope has been transmuted. They announced their discovery today in The Institute of Physics journal Journal of Physics D: Applied Physics.
Iodine-129 is one of the major waste products from nuclear power plants and has a half-life of 15.7 million years making it difficult and dangerous to dispose of. Currently, it is encased in glass and buried deep in the earth. Professor Ken Ledingham and colleagues irradiated Iodine-129 with a laser beam and succeeded in turning some of it into Iodine-128 which, with a half life of just 25 minutes, which can be handled with greater safety.
The next step for Professor Ledingham is to develop this technique on an industrial scale and with other radioactive isotopes. He is currently working on a proposal to seek funding to develop a laser system powerful enough to carry our further transmutation studies in the laboratory.
. Professor Ledingham said today: "The discovery we published today shows for the first time that we can transmute isotopes using lasers. Now we need to scale up our methods so that we can deal with the sort of volumes likely to be produced by the nuclear power industry in the future. At present transmutation of radioactive waste which is still many years down the track will be carried out using large accelerators and reactors. Our vision is that since enormous strides have been made in laser technology over the last few years perhaps lasers offer an alternative procedure in the future.
This discovery will also provide an easier way of producing the isotopes needed to operate the PET scanners used in hospitals and in research. These isotopes are currently manufactured in huge machines called cyclotrons, only four of which exist in the UK. Professor Ledingham hopes to be able to apply his technique to the production of these isotopes quickly and believes that this will be a practical reality within the next five years."
