Use No 7.
Digging big holes to dump high level waste in.
No country has got as far as putting the high level waste in yet....
Dr Helen Wallace who wrote the scientific review "Rock Solid" has said:
"This waste is extremely radioactive and very hot so it's going to significantly change the water flow deep underground; the corrosion of materials and the repository will release large quantities of gas which have to escape somehow. The waste will remain dangerous for many generations."
Storing waste above ground must be the "least bad option" because corrosion and leaking could be prevented. Government wants it out of sight so it can push ahead with insane new build and produce yet more waste.
