In the span of a single week, the nuclear power industry's hoped-for U.S. resurgence took a few steps backward as several projects and existing plants from across the country either were shut down or began to face increased scrutiny from regulators due to ongoing problems and financial issues.
美国核监管委员会（NRC）的前成员彼得·布拉德福德（Peter Bradford）声称，挫折使国内核电产能长期降低的幽灵降低了，他现在是佛蒙特州法学院的能源政策和法律教授。布拉德福德说，如果趋势继续下去，“几年前，美国的核功率产出将达到高峰，这将在我们的一生中再次达到。”
挫折是快速连续的。
4月30日，NRC拒绝了北美核创新的许可申请，该公司在得克萨斯州贝城附近的南德克萨斯州项目3和4号申请其2,700兆瓦的项目3和4，这是由于美国以外的一家公司的多数所有权股权，即托斯房以外的公司。- 违反《原子能法》。
杜克能源（Duke Energy）援引降低电力的需求，于5月2日通知了NRC的计划，该计划暂停了其在其北卡罗来纳州韦克县的Shearon Harris核电站Dhiaa Jamil的Shearon Harris核电站，Dhiaa Jamil，Dhiaa Jamil，Dhiaa Jamil，杜克能源核总裁，据称，该计划暂停了其申请的申请。，“我们最近的预测表明，未来15年将不需要哈里斯的其他两个核单位。”
Additionally, on May 7, Dominion permanently shuttered its 556-MW Kewaunee nuclear plant, near Green Bay, Wis. The company stated it was "unable ... to take advantage of economies of scale, and Kewaunee's power-purchase agreements were ending at a time of projected low wholesale electricity prices."
Also in early May, Edison International officials stated they may decide to shut down the utility's 2,350-MW San Onofre nuclear plant in San Diego County, Calif.—currently off line—if it can't overcome problems at one of the units, Power magazine reported.
That same week, the Florida Senate unanimously passed new restrictions on the state's nuclear cost-recovery law, which allows utilities to charge customers for the costs of nuclear projects years ahead of the start of construction. Among other requirements, the new regulations will force utilities to prove their planned projects have "reasonable" costs.
杜克能源公司（Duke Energy）提议在利维县（Levy County）提议的200亿美元，2,200兆瓦的项目，在佛罗里达州政治辩论的中心进行了一个项目。
2008年宣布的时候,进步能源,since merged with Duke, estimated the cost of the project at about $14 billion. Today, while Duke has yet to state whether or when it will start construction, the utility estimates the plant's cost at between $19 billion and $24 billion. Last November, despite that rise in price—and the growing popularity of natural gas as a cost-effective energy source—the Florida Public Service Commission deemed the project "feasible" and allowed the utility to continue charging customers an additional $143 million in fees, according to the Tampa Bay Times.
