摘要:作為低中水平放射性廢物的最終去向,近地表處置場(chǎng)的安全具有非常重要的意義。結(jié)合某處置場(chǎng)設(shè)計(jì)工程,分析近地表處置場(chǎng)關(guān)閉后放射性核素釋放景象,并建立模型論證其對(duì)環(huán)境的影響。結(jié)果表明,近地表處置場(chǎng)關(guān)閉后,放射性核素遷移對(duì)公眾劑量很小,滿足國(guó)家標(biāo)準(zhǔn)對(duì)公眾照射劑量約束值的要求。
關(guān)鍵詞:放射性廢物;處置;釋放景象;環(huán)境影響

Abstract: As the ultimate destination of low-level radioactive waste, the safety of near surface disposal facilities is of great significance. Based on the design project of a disposal facilities, analyze the radioactive nuclide release scene after the closure of a near surface disposal facilities, and establish a model to demonstrate its impact on the environment. The results indicate that after the closure of the near surface disposal facilities, the migration of radioactive nuclides has a very small impact on the public dose, meeting the requirements of the national standard for the constraint value of public exposure dose.
Keywords: radioactive waste; disposal; releasing scenario; environment impact
