The Ultra-High Temperature Reactor Experiment (UHTREX) was an experimental gas-cooled nuclear reactor run at Los Alamos National Laboratory between 1959 and 1971 as part of research into reducing the cost of nuclear power. Its purpose was to test and compare the advantages of using a simple fuel against the disadvantages of a contaminated . It first achieved full power in 1969. The experiment was a spin-off from the technology developed by the earlier ROVER project.

  • Le Ultra High Temperature Reactor Experiment (UHTREX), littéralement « réacteur expérimental à ultra-haute température », est un réacteur nucléaire expérimental américain, de type graphite-gaz, développé dans les années 1960. Le but était d'étudier un réacteur utilisant un combustible simple, donc avec un coût de fonctionnement réduit, au prix d'une contamination du circuit primaire. (fr)

  • L'Ultra High Temperature Reactor Experiment (UHTREX) era un esperimento effettuato su un reattore nucleare raffreddato a gas sperimentale iniziato nel 1959 e durato circa 12 anni. UHTREX era situato presso i laboratori di Los Alamos e raggiunse la sua piena potenza nel 1969. L'obbiettivo dell'esperimento era di testare i vantaggi di usare un carburante semplice contro gli svantaggi di un ciclo di raffreddamento contaminato con l'obbiettivo finale di trovare maniere per ridurre i costi dell'energia nucleare. Il concetto dell'UHTREX nacque dalla precedente tecnologia sviluppata nel progetto del ROVER. (it)
  • 超高溫實驗堆(UHTREX)是美國一座實驗性質的反應堆。1959年,該反應堆在洛斯阿拉莫斯国家实验室建成,並作爲一個實驗性電站一直運行到1971年退役。 在設計上,該反應堆屬於高溫氣冷堆,使用石墨作爲減速劑,氦作爲冷卻劑。 超高溫實驗堆有兩個突出的特點,有別于一般的高温气冷堆。其一是超高溫實驗堆的出口溫度可達1,300 °C以上,比高溫氣冷堆的出口溫度更高,有利於提高換能效率。另一點是其設計中冷卻回路會受到裂變產物的污染,以簡化反應堆設計並降低成本。這在安全上可能有不利影響。 超高溫實驗堆的目的就在於評估這些優缺點的利弊。 該反應堆于1969年實現滿功率發電。 超高溫實驗堆是美國核热火箭計劃的後續研究。 (zh)
