汉福特场废物罐安全问题的产生在于安全分析不足，以及浓缩阶段放热化学反应（有机溶剂燃烧，有机络合物－硝酸盐反应，亚铁氰化物－硝酸盐反应）期间引起的放射性释放的高度不确定性。解决有机络合物、有机溶剂、亚铁氰化物的安全问题的方法，自１９９０年以来已有很大变更。以前采用罐芯取样及全面分析样品的方法，期望得到的数据能揭示危害的实质。这种方法费用大，而产生的大量数据对解决安全问题的作用很有限。新的方法将着力于认识危害景象，以便集中对那些确保废物安全储存起关键作用的物质进行取样和分析。
The Hanford pit waste tank safety problem results from inadequate safety analysis and the release of radioactive releases during the exothermic chemical reaction (organic solvent combustion, organic complex-nitrate reaction, ferrocyanide-nitrate reaction) during the concentration phase Highly uncertain. The solution to the safety issues of organic complexes, organic solvents, and ferrocyanides has changed dramatically since 1990. In the past, the method of sample sampling and comprehensive analysis of samples was used. The expected data can reveal the essence of the hazard. This method is costly and the large amount of data generated has a limited effect on the security issue. The new approach will focus on identifying hazards and focusing on sampling and analyzing those substances that play a key role in ensuring the safe storage of waste.
