Japan's Nuclear Regulation Authority decided Wednesday to revise its nuclear disaster response guidelines, mainly to clarify the conditions for lifting a shelter-in-place order.

In response to a report proposing a review of how to implement shelter-in-place orders that was compiled by an NRA expert team, the nuclear safety watchdog will also add a section on cases in which going outside should be permitted while such an order is in place.

The NRA's Secretariat will draw up a draft to revise the guidelines, which are expected to be officially adopted around autumn.
