Reuters was recently given exclusive access to the Fukushima No. 1 nuclear plant, where three reactors melted down in 2011 after a powerful earthquake and tsunami overwhelmed the seaside facility.
It was my fourth visit to the plant since the disaster to report on a massive clean-up. Work to dismantle the plant has taken nearly a decade so far, but with Tokyo due to host the Olympics this summer — including some events less than 60 km (38 miles) from the power station — there has been renewed focus on safeguarding the venues.
Nearly 10 years into the decadeslong clean-up some progress has been made, with potentially dangerous spent fuel removed from the top of one damaged reactor building and removal underway from another.
