ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

The Sodium Reactor Experiment
In February 1957, construction was completed on the Sodium Reactor Experiment (SRE), a sodium-cooled, graphite-moderated reactor with an output of 20 MWt. The design of theSRE had begun three years earlier in 1954, and construction started in April 1955. On April 25, 1957, the reactor reached criticality, and the SRE operated until February 1964.

Making new nuclear investments is a challenging task. Their “value” is neither given nor stable: It is constantly being reformulated through processes of evaluation and, therefore, of valuation. The paper follows the specific uses of a standard method, the levelized cost of electricity, by different centers of calculations during a period marked by the intense scrutiny of nuclear energy policy and of the adoption of alternative nuclear fuel cycle technologies: from the George W. Bush administration through the beginning of the Barack Obama administration. Rather than concentrating on the finality of those calculations and their subsequent effects on the reordering of spent nuclear fuel as “waste” or “value,” the author develops the notion of “style of revaluation” and shows how concerned actors enacted different logics of valuation and embedded different audiences in their uses of the same calculative device. The paper characterizes two styles of revaluation related with this period. In the first style, referred to here as the “monetary figures of dissent,” a multitude of disagreements over political and moral values associated with alternative fuel cycle technologies are translated into into the language of economic expertise and monetary figures, while policy makers are designated as the audience for the calculations. In the second style, which the author refers to as the “return-on-investment,” financial investor at large is considered as the audience for the calculations, and investment is to be guided by the morality of the return-on-investment. Such assessments are critical for science and democracy. It is crucial that their designers and users, whether those are academics, practitioners, or policy makers, acknowledge and articulate moral and political values they inscribe in them.
