由微软创始人比尔·盖茨（Bill Gates）支持的设计初创公司Terrapower LLC选择在Wyo。凯默勒（Wyo。该公司在2025年11月17日表示，估计项目成本估计为40亿美元。
The firm and its partners had previously narrowed the project location to four set-to-retire coal plant sites in the state for what it said earlier this year would be a $1-billion demonstration project. Sites in Gillette, Glenrock and Rock Springs also were considered.
Terrapower首席执行官Chris Levesque表示，第一家工厂总是更昂贵，而没有提供四倍成本背后的更多细节。他说，该公司希望在怀俄明州的其他前煤炭原始遗址以及美国其他地方（如果建造）将未来的纳特里姆设施的价格降低到10亿美元。
美国能源部称Natrium钠冷却反应堆为“高级核反应堆技术的未来”，已达成7年的协议，可提供20亿美元的项目开发资金。最近签署的基础设施法案包含25亿美元所有高级反应堆演示的资金分配，其中一些将添加到先前的支持中。
Terrapower将与所有联邦示威资金相匹配。Bechtel正在管理项目设计，许可，采购和建设。它建造了诺顿燃煤电厂，该工厂于1963年开业。核电站预计将创造约2000个建筑工作。
怀俄明州在2019年在美国开采的所有煤炭中生产了约39％燃气发电厂和水力发电设施生产其余部分。
Bechtel还领导一个包括Ge-Hitachi和Terrapower在内的团队去年被巴特尔ergy Alliance, which operates DOE's Idaho National Laboratory, to design and build at the Idaho Falls research site, the first phase of the planned Versatile Test Reactor research facility that will develop advanced nuclear fuels, materials, instruments and sensors.
现场选择因素
The project team evaluated Wyoming site options using several factors, including access to existing infrastructure, the physical characteristics of the site, community support and the ability to obtain a license from the U.S. Nuclear Regulatory Commission. The selection still is subject to completing definitive agreements and permitting and licensing support, TerraPower said.
Levesque说，NATRIUM技术包括带有熔融盐的储能系统的345兆瓦钠冷水快速反应堆，这是第一个高级反应器。储能可以将工厂产量提高到500兆瓦，约五个半小时，这使其可以遵循每日的负载变化，并有助于更轻松地集成可再生资源。
Natrium是GE Hitachi和Terrapower的联合技术，盖茨成立并担任董事长。
随着选择的网站，高级植物设计将继续前进。建筑许可已提交给核监管委员会，其工作预计要到2024年才开始。
The demonstration project, when completed by 2028, will be a fully functioning commercial powerplant to be operated by Rocky Mountain Power, which will use existing energy infrastructure, including connections to the power grid, said Gary Hoogeveen, power company president and CEO, in a press briefing.
它是DOE支持的两个非冷却的小核反应示威之一。有20多家公司正在开发高级反应堆，包括Westinghouse，Holtec International，Nuscale Power和X-Energy。
Terrapower吹捧其熔融氯化物快速反应技术，适用于高能消耗的行业。该公司表示，它的温度比常规反应堆高，在没有排放的情况下会产生更多的电力，并可以帮助行业达到脱碳目标。
另外，Power Company Southern Co.宣布了11月18日that it signed an agreement with DOE to demonstrate what it said is the world's first fast-spectrum salt reactor, in collaboration with TerraPower and Idaho National Laboratory. The facility would be built at that research site.
项目团队成员还包括Core Power，Orano Federal Services，Electric Power Research Institute和3M Co.DOE。
The prototype, which uses a different reactor design than TerrraPower's Wyoming plant, could be adapted to support a 720-MW commercial scale reactor, Southern Co. says.
