The latest ideas to prevent the escape of radiation from Japan's stricken Fukushima nuclear plant are to discharge 11,500 tonnes of contaminated water into the Pacific and plug leaks with an absorbent polymer mixed with sawdust and shredded newspaper. The first idea is a last-ditch effort to free up room for even more highly radioactive water leaking at the site; the second does not yet seem to be working.
The Fukushima plant remains in a critical condition, and solutions to immediate problems are not forthcoming.
That's why we're looking for your views on the best ways to make the plant safe again. In particular, we're looking for opinions from experts with knowledge of the nuclear industry, but whether you're an engineer in the field, an academic, or a nuclear plant worker, we'd like to hear from you.
