This study aims to investigate nuclear safety policy awareness in six OECD countries (i.e. Japan, France, Germany, Sweden, the UK, and the US) during the last decade through text mining on related government documents. Our results show that Germany was the only country that had heightened its policy awareness of both nuclear safety and accident from 2010 to 2012. Moreover, the UK and the US had heightened their policy awareness of nuclear accidents from 2011 to 2012. On the other hand, French policymakers had been less willing to attach great importance to nuclear safety after the Fukushima accident. From 2013 to 2016, Japanese policymakers had been showing a declining emphasis on nuclear safety despite the fact that Japan had been deeply victimized because of the Fukushima nuclear disaster. The findings of this study may help enrich the current nuclear policy discourse.
