Experts from the United Nations nuclear watchdog congratulated Japan for its efforts to decommission the crippled Fukushima nuclear power plant. However, they said, there are still some complex issues that will challenge the decommissioning team and they have to be solved in order to ensure the plant’s stability.
“Japan has established a good foundation to improve its strategy and to allocate the necessary resources to conduct the safe decommissioning of Fukushima Daiichi,” said team leader Juan Carlos Lentijo, Director of Nuclear Fuel Cycle and Waste Technology at the International Atomic Energy Agency (IAEA).
“The situation, however, remains very complex, and there will continue to be very challenging issues that must be resolved to ensure the plant’s long-term stability,” he added.
The 19-member team from the IAEA that visited the site from 25 November to 4 December praised Japan for adopting “a more proactive approach”, the international press reports.
In the IAEA team preliminary report, the experts added that there are certain areas where current practices could be improved, such as preventing groundwater from entering the reactor buildings and monitoring the effectiveness of such measures.
“Regarding the growing amounts of contaminated water at the site, TEPCO should bolster its efforts to treat this water and then examine all options for its further management, including the possibility of resuming controlled discharges in compliance with authorized limits,” said the team.
The final report made by the IAEA team will be delivered to Japan by the end of January.
