The Nuclear Regulation Authority presented a draft outline Monday of new safety measures to prevent or minimize the consequences of severe atomic plant crises.

Among other features, the NRA said utilities will be required to build a special safety facility housing a secondary control room for reactor operations to protect reactors against natural disasters and acts of terrorism, such as the intentional crashing of an aircraft into a nuclear plant.

The new safety standards are expected to come into force in July, replacing the current ones, which the triple-meltdown disaster that erupted in March 2011 at the Fukushima No. 1 plant proved were insufficient.
