The very high temperature reactor (VHTR), or high temperature gas-cooled reactor (HTGR), is a Generation IV reactor concept that uses a graphite-moderated nuclear reactor with a once-through uranium fuel cycle. The VHTR is a type of high temperature reactor (HTR) that can conceptually have an outlet temperature of 1000°C. The reactor core can be either a “prismatic block” or a "pebble-bed" core. The high temperatures enable applications such as process heat or hydrogen production via the thermochemical sulfur-iodine cycle.

Famous quotes containing the words high and/or temperature:
“As the Arab proverb says, “The dog barks and the caravan passes”. After having dropped this quotation, Mr. Norpois stopped to judge the effect it had on us. It was great; the proverb was known to us: it had been replaced that year among men of high worth by this other: “Whoever sows the wind reaps the storm”, which had needed some rest since it was not as indefatigable and hardy as, “Working for the King of Prussia”.”
—Marcel Proust (1871–1922)
“The siren south is well enough, but New York, at the beginning of March, is a hoyden we would not care to miss—a drafty wench, her temperature up and down, full of bold promises and dust in the eye.”
—E.B. (Elwyn Brooks)
