NRA decided not to apply INES evaluation to Fukushima plant anymore

(Before It's News)

On 12/10/2014, NRA (Nuclear Regulation Authority) announced they are not going to apply INES (International Nuclear Estimation System) to any further accidents in Fukushima plant.

Severe contamination leakage continues to occur in Fukushima plant.

The leakage that occurred in August 2013 was evaluated as INES Level 3, another leakage that occurred this February is also assumed to be evaluated as INES Level 3.

(cf, [Level.7 Plus] Nuclear Regulation Authority classified H4 tank area leakage as INES Level.3 [URL 1])

(cf, [100m3 overflow] Accident scale INES level 3 potentially / The amount of damage up to a few million USD [URL 2])

Literally, Fukushima accident is now evaluated as Level 7 + 3 + 3.

As the reason why NRA abandons INES, they point out that they cannot prepare deep safeguard in the crippled plant anymore, however no significant increase in radioactive density was observed offshore Fukushima.

NRA is only going to qualitatively explain the outline of the potential accident and effect to the environment instead of indicating INES level.
