Experimental investigations relevant for hydrogen and fission product issues raised by the Fukushima accident

Current Research and Development Activities on Fission Products and Hydrogen Risk after the Accident at Fukushima Daiichi Nuclear Power Station

After the Fukushima Daiichi nuclear power plant (NPP) accident, new regulatory requirements were enforced in July 2013 and a backfit was required for all existing nuclear power plants. It is required to take measures to prevent severe accidents and mitigate their radiological consequences. The Regulatory Standard and Research Department, Secretariat of Nuclear Regulation Authority (S/NRA/R) has...

The Fukushima Accident

On March 11, 2011 an unusually strong earthquake, now called the Tohoku earthquake, occurred off the north-eastern coast of Japan's main island, Honshu. While the earthquake caused some destruction, the ensuing tsunami about three quarters of an hour later largely destroyed numbers of towns and devasted cities such as Sendai. http://earthquake.usgs.gov/earthquakes/eqarchives/poster/2011/2011031...

Potassium iodide prophylaxis: what have we learned and questions raised by the accident at the Fukushima Daiichi Nuclear Power Plant.

There is no doubt that when potassium iodide (KI) is administered in a timely fashion, much of the potential exposure to radioactive iodine isotopes from an atmospheric release can be safely averted (1–3). The United States of America Food andDrug Administration (FDA) and theWorld Health Organization (WHO), among others, have established guidelines for the use of KI in these settings (4,5). Leg...

Assessment of atmospheric dispersion from ANPP hypothetical accident based on Fukushima accident by HYSPLIT model

The atmospheric dispersion of Materials is one of the most important ways of spreading contamination of a NPP accident. In this study, the particle paths were calculated by HYSPLIT model (both pressure and AGL form of trajectory) horizontally and vertically at 0 and 1.5 meters above ground level during 15-day periods for 23& 24 November 2006 start times. Then, the releases values of Fukushima a...
