The Nuclear Regulation Authority said Wednesday its planned new safety standards to deal with serious atomic crises in the event of earthquakes and tsunami could affect the reactivation of the country's reactors.

The NRA will solicit public comments on the standards as well as other regulations, including a process to give exceptional extension to reactors operating more than 40 years, as the country continues to grapple with the Fukushima No. 1 nuclear plant disaster triggered by the March 2011 megaquake and tsunami.

Public opinion will be courted for 30 days from Thursday and could be reflected in the standards, which will be enforced from mid-July.
