The Nuclear and Industrial Safety Agency on Friday submitted the outline of a two-stage stress test for the nation's reactors, focusing on four categories, including earthquakes, tsunami, loss of power sources and loss of cooling systems for fuel rods.
According to the outline submitted to the Nuclear Safety Commission, the first stage will target reactors currently out of operation for regular inspections and maintenance.
The government will decide if the reactors are able to endure severe events beyond the current safety standards in terms of the four categories.
