摘 要: | 为获得核废料储罐与周围环境界面的温湿度信息,以便模拟不同地质处置时期储罐表面的腐蚀环境,通过对一些典型核能利用国家在高放核废料安全处置研究中对储罐表面温度的长期演变计算进行调研,结合不同埋藏模式推测出适于我国的核废料储罐表面温度演变规律。同时根据国内外对核废料储库中缓冲/回填材料饱和度的变化情况推测我国核废料储罐表面环境中膨润土含水量的时间演变趋势。研究表明,储罐表面初始时温度快速升高,至温度峰值后逐渐下降,为安全起见,最高温应设计低于100℃。膨润土的饱和度受到核废料衰变释热及地下水入渗的双重影响,早期以核废料衰变主导,后来受地下水入渗影响显著。一般认为储罐表面膨润土在3年左右含水量明显增加,约10年左右达到饱和。温湿度长期演变预测将为我国核废料储罐表面腐蚀演变研究奠定基础。
