核废物处置后因所含的放射性核素衰变而产生的衰变热通过传导、对流以及辐射等方式从废物体向外传递，从而引起废物罐体、缓冲材料及近场围岩温度升高，导致废物体至近场围岩之间形成温度梯度。温度梯度随着时间的延续而变化，最终会影响地下水系统和核素迁移。本文对一些国家的处置库温度预测模式进行了调研，对源项、处置库模型简化、热传递数学模型和模拟结果做了初步总结，为我国拟建处置库的温度场预测提出了建议。

Heat arising from decay of the radionuclides in the nuclear waste transmits outward by the conduc-tion ,convection and radiation .It results in temperature rising in containers ,buffer and near field host ,which leads to temperature gratitude to be formed between waste and host .The time-dependent gratitude variations eventually affect the ground water system and radionuclide migration .It is necessary to calculate and predict the near field temperature .This study investigates thermal analyses of the repositories in some countries and present a preliminary summary of the source terms ,simplified repository model ,calculation methodology and results ,which could be as a reference for HLW repository in China .
