    en.wikipedia.org/wiki/PUREX

    PUREX (plutonium uranium reduction extraction) is a chemical method used to purify fuel for nuclear reactors or nuclear weapons. [7] PUREX is the de facto standard aqueous nuclear reprocessing method for the recovery of uranium and plutonium from used nuclear fuel ( spent nuclear fuel , or irradiated nuclear fuel).

  4. Chemical plant cost indexes - Wikipedia

    en.wikipedia.org/wiki/Chemical_plant_cost_indexes

    A cost index is the ratio of the actual price in a time period compared to that in a selected base period (a defined point in time or the average price in a certain year), multiplied by 100. Raw materials, products and energy prices, labor and construction costs change at different rates, and plant construction cost indexes are actually a ...

    en.wikipedia.org/wiki/Nuclear_reprocessing

    The first large-scale nuclear reactors were built during World War II.These reactors were designed for the production of plutonium for use in nuclear weapons.The only reprocessing required, therefore, was the extraction of the plutonium (free of fission-product contamination) from the spent natural uranium fuel.

    The Thermal Oxide Reprocessing Plant, or THORP, is a nuclear fuel reprocessing plant at Sellafield in Cumbria, England. THORP is owned by the Nuclear Decommissioning Authority and operated by Sellafield Ltd , the site licensee.

  7. Price index - Wikipedia

    en.wikipedia.org/wiki/Price_index

    Price indices are represented as index numbers, number values that indicate relative change but not absolute values (i.e. one price index value can be compared to another or a base, but the number alone has no meaning). Price indices generally select a base year and make that index value equal to 100.

  8. List of price index formulas - Wikipedia

    en.wikipedia.org/wiki/List_of_price_index_formulas

    A price index aggregates various combinations of base period prices (), later period prices (), base period quantities (), and later period quantities (). Price index numbers are usually defined either in terms of (actual or hypothetical) expenditures (expenditure = price * quantity) or as different weighted averages of price relatives ( p t ...

    A report by the National Nuclear Security Administration estimated the total cost over a 20-year life cycle for the Savannah river site MOX plant to be $47 billion if the annual funding cap was increased to $500 million or $110 billion if it were increased to $375 million. [16]
