An International Atomic Energy Agency team of experts said in a review published on April 2 that the two options for the controlled disposal of treated water stored at the Fukushima Daiichi nuclear power plant are “technically feasible.” A Japanese advisory subcommittee outlined the two options—vapor release and discharge to the sea—for the water that is being stored at the plant following the 2011 accident.

The International Atomic Energy Agency plans to provide diagnostic kits, equipment, and training in nuclear-­derived detection techniques to countries asking for assistance in tackling the worldwide spread of the coronavirus that has caused the COVID-­19 pandemic. IAEA Director General Rafael Mariano Grossi announced the plans on March 9 during his first formal address to the IAEA’s Board of Governors (see previous story).

“The IAEA is not a specialized health agency and has no role in controlling the disease,” Grossi said, “but we do have expertise and experience that help in detecting outbreaks of certain viral diseases and in diagnosing them.”

Rafael Mariano Grossi, the International Atomic Energy Agency’s director general, called on Iran on March 9 to cooperate immediately and fully with the IAEA and to provide prompt access to locations that it has refused to let agency inspectors visit. “The agency has identified a number of questions related to possible undeclared nuclear material and nuclear-related activities at three locations that have not been declared by Iran,” Grossi said in his first address to the IAEA’s Board of Governors since being named director general in December.

International Atomic Energy Agency member states operating or having previously operated a research reactor are responsible for the safe and sustainable management of associated radioactive waste, including research reactor spent nuclear fuel (RRSNF). Management includes storage and ultimate disposal of RRSNF, or the corresponding equivalent waste generated and returned following reprocessing of the spent fuel. Currently, there are 259 research reactors operating, planned, or under construction around the world [1]. An additional 147 research reactors are in extended or permanent shutdown, or under decommissioning.

One key challenge to developing general recommendations for RRSNF management options lies in the diversity of spent fuel types, locations, and national or regional circumstances, rather than mass or volume alone, particularly since typical RRSNF inventories are relatively small. Currently, many countries lack an effective long-term strategy for managing RRSNF. Many research reactor organizations know they have responsibility for the spent fuel, however, they do not know how to decide among multiple options for its management. A methodical review and compilation of technology options for RRSNF management is needed.
