These concentrated fuels were then reformed, on site, into new fuel elements.

The shoals are concentrated fuel resources for the great marine predators.

Your concentrated fuel; the mighty engine which it can drive; these will revolutionize the most vital of all modern utilities: power.

Iran said it needs the more concentrated fuel for a research reactor in Tehran which makes isotopes for medical uses.

Most important, it also means that the fuel is less dense and reactive than the concentrated fuel rods in conventional reactors.

Camp stoves and concentrated fuel tablets.

Iran has consistently argued that any traces of concentrated fuel must have come from equipment contaminated before it was imported, presumably from Pakistan.

Sparks are an ignition source in combustible environments that may lead to catastrophic explosions in concentrated fuel environments.

Eco Logs are a new product that can be safely used as a concentrated fuel source in all open fireplaces, wood burning heaters and combustion stoves.

The deadliest bits—such as fuel rod casings and other reactor parts as well as concentrated fuel residue containing plutonium and highly enriched uranium—must be sealed and stored away.

Since 2010, Iran has been enriching some of its processed uranium to raise its purity from around 5 percent to 20 percent, saying it needs the concentrated fuel for a research reactor in Tehran.

Despite Iranian disavowals, International Atomic Energy Agency experts in Iran have found evidence of indigenous production of a concentrated fuel that, if pure enough, can be used to make nuclear weapons.

We had enough concentrated fuel to fly the ship for, probably, some fifty years; but we would have to make occasional landings for food and water, and it seemed as though every time we landed something terrible happened to us.

Coal would enable an industrial base to be set up for producing machines suitable for drilling and processing oil, which in turn would yield the more highly concentrated fuels essential for aircraft and rudimentary space vehicles.

However in energy analysis intractable theoretical and practical difficulties arose when using the energy unit to understand, a) the conversion among concentrated fuel types (or energy types), b) the contribution of labour, and c) the contribution of the environment.

In a report on Tuesday, the International Atomic Energy Agency said that its inspections had found that centrifuge equipment made indigenously in Iran - but not imported gear - showed many traces of the concentrated fuel, leading experts to doubt the Iranian explanation and suggest that Iran had enriched the uranium itself.
