OAK RIDGE, Tenn. —
There has been renewed interest in nuclear power in the past few years, and two recent speeches in Oak Ridge touted small modular reactors as an optional energy source, with one possibly located in the Secret City.
Those small reactors could produce 125 megawatts, or about one-tenth the power of a large, traditional nuclear reactor.
U.S. Sen. Lamar Alexander, a Tennessee Republican, has urged Energy Secretary Steven Chu to consider using a small, modular reactor at Oak Ridge National Laboratory. A 125-megawatt nuclear reactor could generate enough electricity to power the Oak Ridge National Laboratory and the Y-12 National Security Complex.
One possible site would be the former Clinch River Breeder Reactor site, a 1,300-acre site in West Oak Ridge, where a now-scrapped reactor was to be built in the 1980s.
At one of the two recent speeches, Andrea Sterdis, Tennessee Valley Authority senior manager for strategic nuclear expansion, said the public utility is trying to help make the Oak Ridge Reservation, which uses lots of electricity for supercomputers and other activities, become "greener." Only 30 percent of the power supplied by TVA, which mostly relies on coal-fired plants, is "clean electricity," Sterdis said.
Powering Y-12 and ORNL with a small modular reactor could allow the two U.S. Department of Energy facilities to disengage from the main electrical grid, Sterdis said during a recent presentation at Lunch with the League, a regular event sponsored by the League of Women Voters of Oak Ridge.
"That's a big security advantage," she said.
A small modular reactor could reportedly cost between $500 million and $800 million.
According to lab officials, ORNL is interested in the proposal because it could, among other things, reduce carbon dioxide emissions produced by power plants that supply the lab's electricity.
ORNL Director Thom Mason has said there is a new federal executive order to "green the government," with a goal of trying to reduce carbon dioxide emissions during the next 10 years. He said the proposed 125-megawatt reactor would make the Oak Ridge Reservation's electrical supply "non-emitting."
Alexander said the reactor would meet 48 percent of DOE's greenhouse gas reduction goals.
Sterdis said atomic energy can reliably provide electricity at competitive rates and with no emissions while boosting economic development. She said the costs of coal and nuclear power, in terms of cents per killowatt-hour, are much lower than gas and oil plants, and also less volatile.
"You have to think about the reliability of it all and what it's going to cost," Sterdis said, comparing nuclear power to renewable energy, including wind turbines.
"Tennessee is not a great place to put up wind turbines," Sterdis said.
While the operating costs of nuclear power are very low, the "upfront" construction costs are high, Sterdis said.
Of course, there are issues associated with using nuclear power, including the controversial question of what to do with the used fuel.
In June 2009, Babcock and Wilcox Co. of Lynchburg, Va., announced plans for a new class of small reactors to be built in North American factories and shipped by rail to generating sites. At that time, a TVA executive said the public utility would study the Clinch River Breeder Reactor site as a potential home for one of the reactors.

橡树岭，田纳西州 -
人们又开始在过去几年中，核电的兴趣，并在橡树岭两个近期的演讲中吹捧为一个可选的能源反应堆小型化，模块化，可能是在位于城市的秘密之一。
这些小型反应堆可以生产125兆瓦，约占十分之一，而大型的，传统的核反应堆功率。
美国参议员拉马尔亚历山大，田纳西州共和党，敦促能源部长史蒂芬朱可考虑使用在橡树岭国家实验室的一个小的，模块化的反应堆。一个125兆瓦的核反应堆可以产生足够的电力橡树岭国家实验室和Y - 12国家安全情结。
一个可能的地点将是前克林奇里弗堆站点，在西橡树岭，那里现在已经报废反应器将在20世纪80年代建成1300亩的网站。
在最近两次讲话，安德烈Sterdis，为战略核扩张田纳西河谷管理局高级经理一说，公用事业是试图帮助美国橡树岭保留，其使用的超级计算机和其他活动大量电力，成为“绿。 “只有30所TVA的，主要表现在燃煤电厂供应的电力百分之依赖，是“清洁电力”Sterdis说。
供电Ÿ - 12和橡树岭国家实验室的一个小模块式反应堆可能允许这两家美国能源部设施脱离主电网，Sterdis在午餐时说，与阿拉伯联盟，定期举行的活动由妇女选民联盟主办的最新介绍橡树岭。
“这是一个巨大的安全优势，”她说。
一个小的模块式反应堆可报售价介于500万美元和8亿美元。
据实验室的官员，在橡树岭国家实验室是因为它可以建议，除其他外，减少二氧化碳的发电厂，供应该实验室的电力生产排放的兴趣。
橡树岭国家实验室主任托姆梅森说有一个新的联邦政府行政命令，“绿色政府”，以试图减少在未来10年的二氧化碳排放的目标。他说，建议125兆瓦的反应堆将使橡树岭预定的电力供应“的非发光。”
亚历山大说，反应堆将达到48能源部的温室气体减排目标的百分比。
Sterdis说原子能可以提供可靠的电力竞争力的价格和无排放，同时促进经济发展。她说，每千瓦小时美分计算，煤炭和核能，成本要比石油和天然气厂低，也较少波动。
“你必须考虑这一切，哪些是要成本的可靠性，”Sterdis说，比较核电可再生能源，包括风力涡轮机。
“田纳西州是不是一个伟大的地方竖起风力涡轮机，”Sterdis说。
虽然核电的经营成本非常低，“前期”的建设成本高，Sterdis说。
当然，有与使用核力量，包括如何处理用过的燃料问题有关的争议问题。
2009年6月，巴威的林奇堡，弗吉尼亚州的公司，宣布了新一类的小型反应堆计划建在北美的工厂，并通过铁路运到生成的网站。当时，一TVA的高管表示，公共事业将研究克林奇里弗堆，作为一个潜在的反应堆主站点。
