More hospitals capable of treating a large number of patients, designating more hospitals to handle patients with serious radiation exposure and creating an emergency team of experienced doctors will be key components in reinforcing the nation's medical preparedness for nuclear disasters.

Working on lessons learned from the 2011 Fukushima crisis, the Nuclear Regulation Authority has worked out plans to significantly upgrade the medical care framework for potential disasters, NRA sources said Tuesday.

The agency plans to set up a panel of experts tasked with working out further details of the framework by March.
