What is differentiation enriched uranium?

Enriched uranium is an uranium with more than 0,7 % uranium 235.


What are the positive enriched uranium?

- the energy released from enriched uranium is higher compared to natural uranium- the amount of uranium needed for a reactor is lower- research reactors work only with enriched uranium- atomic bombs have highly enriched uranium or plutonium


What element if often enriched and used in nuclear bombs?

Uranium is enriched in the isotope uranium-235, producing uranium-238 as waste.


How much is enriched uranium?

Uranium can be enriched to 99,9 %.But usually, for the use in nuclear reactors, the enrichment is under 20 %.


Elements used to generate nuclear energy?

Uranium, Plutonium and Thorium...the most common being uranium which when dug out of the ground is 99.3% uranium238 and only 0.7% uranium235. U235 is the nuclei best suited to nuclear fission which means natural uranium is enriched to raise the percentage of U235 to about 3-5% (enriched uranium)...this creates a lot of waste U238 which could be made into plutonium but is usually just stored. If the final use of the uranium is a bomb rather than energy, the enrichment percentage increases far more.


Is plutonium and enriched uranium the same thing?

Plutonium and enriched uranium are different materials.Enriched uranium is uranium with a concentration of the isotope 235U greater than the natural concentration of 0,7 %.


What are the hazards of Uranium?

Uranium is toxic and radioactive; the highly enriched uranium has a risk of criticality.


When uranium will blast?

Uranium will blast only when a mass of enriched uranium attain the critical mass.


Does uranium need to be enriched in order to be used in a nuclear reactor?

Some nuclear power reactors work with low enriched uranium; CANDU reactors work with natural uranium.


Is uranium used in missiles?

Only if these missiles transport bombs with enriched uranium.


How many moles are in a 140 grams of uranium?

divide 140 by the atomic weight of the uranium you want to know about. it will be different if you are asking about natural, enriched, or depleted uranium and how much its enriched or depleted.


What are the disadvantages of enriched uranium?

Disadvantages of enriched uranium:- it is very difficult to prepare- can be used for bombs- the price is prohibitive- need of a complicate and expensive technology


How much does enriched uranium cost?

This depends on the enrichment.


What is the Uranium bomb?

Is uranium used in atomic bombs?

Yes, enriched uranium can be used in atomic bombs.


Enriched uranium uranium 235 or uranium 238?

Enriched uranium is still usually mainly 238U, but it has a higher percentage of 235U than the natural abundance. Depleted uranium is exactly the opposite: it's got a LOWER than normal amount of 235U.


What is uranium - 235 when added to natural uranium?

Natural uranium has approx. 0,7 % 235U; uranium with more than 0,7 % 235U is an enriched uranium.


Name the element once enriched can form the core of a nuclear bomb?

Uranium hexafluoride (hex) is a compound of uranium that becomes a gas when heated. In gaseous form, it can be "enriched". Enriched uranium is needed for research reactors, most non-Canadian power reactors, and bombs.


Does CANDU reactor use enriched uranium?

CANDU Reactors are specifically designed such that they do not require enriched uranium, and can operate entirely on naturally-occurring uranium. A CANDU design is generally used by parties that do not desire uranium enrichment facilities, due to the cost of those facilities. That said, a CANDU reactor CAN use enriched uranium, they are fully capable of supporting that fuel type.


What type of bomb was Little Boy?

Little Boy was a bomb with enriched (in uranium 235) uranium.

Why does uranium explode?

Uranium explode when the critical mass of enriched uranium is reached and the uncontrolled nuclear fission reaction begin.

Is uranium or plutonium used as fuel in a nuclear reactor?

Though both enriched uranium and plutonium can be used, the most common in enriched Uranium-235. The waste that comes from the reaction is a mix of elements (uranium, plutonium, etc) http://en.wikipedia.org/wiki/Nuclear_power
