Le Southwest Experimental Fast Oxide React … Le Southwest Experimental Fast Oxide Reactor (SEFOR, en français : « réacteur expérimental à oxyde rapide du Sud-Ouest ») est un réacteur surgénérateur localisé à Cove Creek Township. Ce réacteur consiste en un réacteur experimental fonctionnant au combustible MOX et refroidit au sodium et d'une puissance de 20MWt (puissance thermique). Il a fonctionné de 1969 à 1972. Il a été exploité par General Electric et financé par le gouvernement des États-Unis via la Southwest Atomic Energy Associates, un consortium à but non lucratif formé par 17 compagnies d'électricité du Southwest Power Pool et des agences nucléaires européennes.ool et des agences nucléaires européennes.
, SEFOR (Southwest Experimental Fast Oxide R … SEFOR (Southwest Experimental Fast Oxide Reactor) was an experimental fast breeder reactor located in Cove Creek Township, Washington County, near Strickler, in northwest Arkansas (20 miles southwest of Fayetteville, Arkansas). The site consisted of a 20-Megawatt (thermal), Sodium-Cooled Test Reactor, a Shop Building, an Operations Building, a Maintenance Shed, and an Electrical Transformer yard. It operated from 1969 to 1972 when the program ended. It was then acquired by the University of Arkansas, in hopes that it could be used as a research facility in 1975, but it never happened. The University maintained the decommissioned site until finally receiving federal funds to dismantle the facility in 2016, which completed in 2019. It used MOX fuel and liquid sodium cooling, and generated 20MW of heat but no electricity. It was constructed particularly to test the suggested inherent safety features of the oxide fuel/sodium cooling configuration, and in particular the effect on the core of thermal expansion, including in an accident situation. The belief that this would stabilize the core was confirmed. The design concept of using thermal expansion to stabilize a reactor core has since been featured in other reactor designs, notably in the pebble bed reactor, which is however neither a fast neutron reactor nor a breeder reactor, and in subsequent Fast breeder reactors. SEFOR operated from 1969 to 1972, when the original program was completed as planned. It was privately operated by General Electric and funded by the United States government through the Southwest Atomic Energy Associates, a nonprofit consortium formed by 17 power companies of the Southwest Power Pool and European nuclear agencies. A proposal for funding to extend its operation to 1977 was rejected prior to the closure in 1972. The fuel and irradiated sodium coolant were removed and taken offsite later in 1972, and the facility was placed in safe storage. The reactor was acquired by the University of Arkansas in 1975, and was used to calibrate equipment and as a research tool for graduate students. SEFOR was designated a Nuclear Historic Landmark site in October 1986, and that same year the university stopped using the facility but continued to maintain surveillance through maintenance activities and periodic visits to the reactor. A caretaker also lived on site in the former Visitors’ Center.ed on site in the former Visitors’ Center.
, SEFOR (Southwest Experimental Fast Oxide R … SEFOR (Southwest Experimental Fast Oxide Reactor, es decir, Reactor Experimental de Óxido Rápido del Sudoeste) es un experimental desactivado situado cerca de , en el noroeste de Arkansas. Utilizaba combustible MOX y estaba refrigerado por sodio líquido, y generaba 20MW de calor pero no electricidad. Se construyó en especial para probar las características supuestas de seguridad inherentes a la configuración de combustible de óxido/refrigeración por sodio líquido, y, en particular, el efecto en el núcleo del reactor de la expansión térmica, incluida la de una situación de accidente. La creencia de que esta configuración pudiera estabilizar el núcleo fue confirmada. SEFOR funcionó desde 1969 a 1972, cuando el programa original se completó de acuerdo con lo planificado. Su funcionamiento corría a cargo de General Electric y estaba dotado financieramente por el gobierno de los Estados Unidos a través de Southwest Atomic Energy Associates, un consorcio sin ánimo de lucro formado por 17 compañías de energía y agencias nucleares europeas. Una propuesta para subvencionar la continuación de su funcionamiento hasta 1977 fue rechazada con anterioridad a su cierre en 1972. El combustible y el refrigerante de sodio irradiado fueron retirados más tarde en 1972, y se realizó algunas labores de desmantelamiento. El reactor fue adquirido por la Universidad de Arkansas en 1975 que sigue detentando su propiedad, aunque la universidad no lo ha hecho funcionar nunca. SEFOR fue designado como emplazamiento nuclear histórico en octubre de 1986. El concepto de diseño de utilizar la expansión térmica para estabilizar el núcleo de un reactor ha sido desde entonces incorporado a otros diseños de reactores, en especial en el el cual, no obstante, no es un reactor de neutrones rápidos ni un reactor reproductor de neutrones. El emplazamiento todavía sigue contaminado con material radiactivo, asbestos y residuos químicos. Con datos de 2005, la universidad sigue buscando una dotación de 16 millones de dólares para los trabajos de descontaminación. La senadora por Arkansas, Blanche Lincoln, inició los intentos para conseguir fondos en 1999. En 2005 presentó la legislación para la desinstalación y descontaminación de SEFOR en la Energy Policy Act de 2005. A pesar de que la disposición fue aprobada y firmada por el Presidente de los Estados Unidos George W. Bush, no se ha conseguido el dinero adecuado para limpiar el emplazamiento.ro adecuado para limpiar el emplazamiento.
