In terms of problems that won't go away, this is the one that's going to hang around for the longest. The nuclear waste we are generating will continue to emit dangerous levels of radiation for tens of thousands of years, so getting rid of this waste needs a solution built to stand the test of time. Developing a disposal site is a long process. Longer, for example, than many political lifetimes, so the issue in the UK has been championed several times before only to fall off the agenda when administrations change or it just became 'too hard'. Now it is back on the agenda, seen as a necessity, and cross-party buy-in appears to guarantee continuity for the project. This paper looks at the location of a site and its geology, together with packaging of the waste, safety aspects and management of the site.
