A South Korean delegation of experts will continue, from home, with its analysis of Japan's plan to discharge treated radioactive water into the sea from the disaster-hit Fukushima nuclear power plant, the group said Thursday after inspecting it.

The delegation of 21 experts from agencies and affiliated organizations of the South Korean government with expertise in radiation and nuclear reactors, among other fields, held a meeting with Japanese officials to summarize their observations following the two-day inspection, telling the Japanese side they still needed to confirm several things before releasing their conclusion on the plan's safety.

They requested additional materials, such as protocols for a power outage and a long-term management plan for an advanced liquid processing system (ALPS) capable of removing radionuclides other than tritium in water.
