Enrichment is measured in an arcane unit called "separative work units."

The competition depressed the price of the fuel, measured in separative work units, or S.W.U.'s.

The number of separative work units provided by an enrichment facility is directly related to the amount of energy that the facility consumes.

Once completed, the commercial plant will use approximately 11,500 centrifuge machines to generate 3.8 million separative work units (SWU) a year.

The SWU (separative work unit)

Every year, these reactors need 13 million to 14 million separative work units (SWU), which measure the amount of work expended during uranium enrichment.

Enrichment is measured by "separative work units," or S.W.U.'s, and the United States market is about 11 million units a year.

In contrast, the deal called for the company to buy the uranium from Russia for $82 per separative work unit in its first annual order, giving it a lower profit margin.

Russian LEU imports sold under contracts for so-called Separative Work Units (SWU) cannot be legally covered.

In response, the company has unsuccessfully sought to recoup the difference from the Federal Government, and also unsuccessfully sought to drive the Russians down to a price of $68 per separative work unit on future orders.

For this reason, enrichment plant capacity is measured in "separative work units", which combines all these factors to provide a measure of the work being performed by the enrichment plant as the Uranium passes through it.

The separative work unit (SWU) is a measure of the amount of work done by the centrifuge and has units of mass (typically kilogram separative work unit).

Separative work is measured in Separative work units SWU, kg SW, or kg UTA (from the German Urantrennarbeit - literally uranium separation work)

The unit is strictly: Kilogram Separative Work Unit, and it measures the quantity of separative work (indicative of energy used in enrichment) when feed and product quantities are expressed in kilograms.

The value of the process is in two components: the LEU Feed (feed component of natural uranium) and the work involved in the conversion process, measured as separative work units (SWU).

In addition to the separative work units provided by an enrichment facility, the other important parameter to be considered is the mass of natural uranium (NU) that is needed to yield a desired mass of enriched uranium.

And then as a side note, I'm just interested in learning whether you're going to introduce the concept of separative work units as the baseline technical definition for enrichment capacity versus a raw number of centrifuges that doesn't (inaudible) people necessarily.

Moreover, the company enjoyed a virtual monopoly in the United States on such work, enriching uranium for about $60 per separative work unit - the standard measure of the effort used in processing varying amounts of the material - and selling it to utilities for $120.

Separative Work Unit (SWU) is a complex unit which is a function of the amount of uranium processed and the degree to which it is enriched, i.e. the extent of increase in the concentration of the U-235 isotope relative to the remainder.
