IAEA Document Reveals Concerns Over Fukushima Communications via Nuc Net

28 Aug (NucNet): The International Atomic Energy Agency (IAEA) has told Japan to consider producing an “appropriate communications” plan to explain the safety significance of incidents at the Fukushima-Daiichi nuclear plant and to avoid sending “possibly confusing” messages to the media and the public.

In a document responding to questions from Japan’s permanent mission to the Vienna-based agency, the IAEA says that with “clear content and appropriate frequency of messages” such a plan would be “highly effective” and would avoid sending confusing messages on a possibly long series of low-level International Nuclear and Radiological Event Scale (INES) incidents throughout the recovery operation at the plant.

The document, posted online by Japan’s Nuclear Regulation Authority (NRA), was a response to questions from Japan about whether or not it should apply an INES rating in the case of a leak earlier this month of contaminated water from a tank.

The leak was first reported on 19 August 2013 when water was discovered inside and outside a dike surrounding the water tank. On 21 August the NRA revised its initial rating of the leak from a Level 1 to a provisional Level 3 on INES.

The IAEA document notes that the leak was the latest in a number of similar events that were not given an INES rating.

It says the application of an INES rating is a national responsibility, but whatever communications strategy is adopted, it is important that the information needed to properly determine an INES rating is collated and that “a defensible” rating is determined.
