要約
原子力発電をめぐる一般の人々・公衆の受容にかかわる研究において，原子力発電の工学的・技術的側面の改善の扱い方には探究の余地がある．本稿では，その探究のための足がかりを得ることを目的とし，原子力発電を活用している各国のあいだでも技術的・工学的な挑戦が一様ではないことに着目した．英文ジャーナル3誌を取り上げ，米仏中の国家間の比較に照準を合わせ，テキスト分析を実施した．結果として，単語やフレーズの出現頻度という点からは，国家間で相関係数が高くなった．他方，アメリカでnuclear waste，フランスでconstruction costs，中国でpublic acceptanceといったフレーズの出現頻度が高くなり，costという単語は中国において出現頻度が低かった．
キーワード 原子力発電，テキスト分析，技術，コスト
Abstract
Studies in public acceptance of nuclear energy have not considered sufficiently technological aspects such as an innovation for safety improvement of nuclear power plants. However, there are some differences among countries which utilize nuclear power generation because the various technological challenges they face are not the same. As an initial step to tackle the problem of this insufficient consideration, this study carried out the quantitative text analysis of applied research studies written in English of three journals, focusing on a comparison of the US, France and China. As a result, in terms of the frequencies of certain word usages, correlation coefficients among countries were high. On the other hand, frequently, the bigram “nuclear waste” was found to be used in the U.S., “construction costs” was found in France, and “public acceptance” was found in China. It is noteworthy; the word “cost” was not found to be used much in China.
