Postnuclear land conversion has gained attention as more civilian nuclear power reactors reach their design life. To date, most former nuclear power plant sites have been converted into another power plant or are sitting idle, often with spent nuclear fuel on site. However, a former nuclear power plant site in the town of Haddam, Connecticut, presents an alternative possibility: land conversion into a nature conservation area. We adopt theoretical vantage points of the geographical political economy literature to analyze the evolution of different discourses and actions relating to the former nuclear site, and examine why and how nuclear-to-nature conversion has gained momentum. The study reveals that the nuclear-to-nature proposition emerged as a political leverage to resolve conflicting interests over land reuse and spent nuclear fuel problems, which eventually engendered active local agency for land conservation. We argue that recognizing multiple articulations of space and associated agency is essential to understand the seemingly contradictory juxtaposition of nature and nuclear.

随着越来越多的民用核动力反应堆达到设计寿命，核后土地转换得到了关注。迄今为止，大多数以前的核电站场址已被改建为另一座发电厂或处于闲置状态，通常现场都装有乏核燃料。但是，康涅狄格州Haddam镇的原核电站场址提出了另一种可能性：将土地转换为自然保护区。我们采用地理政治经济学文献的理论优势来分析与前核基地有关的各种论述和行动的演变，并探讨为什么以及如何使核向自然转化获得动力。该研究表明，核对自然的主张是作为解决土地再利用和乏核燃料问题上利益冲突的政治手段而出现的，最终促成了当地积极的土地保护机构。我们认为，认识到空间和相关机构的多重联系对于理解看似矛盾的自然与核并置至关重要。关键字：地缘政治经济，土地利用，核退役，核能，美国。
