Yes, the nuclear fuel from a nuclear reactor must be replaced at some intervals, because the fuel can be poisoned with neutron absorbers and the clad can become fragile and unsure; the "burned" fuel is recycled.
Some nuclear power reactors work with low enriched uranium; CANDU reactors work with natural uranium.
A typical large power reactor will have approx 75 tons of uranium fuel with about 1/3 of this being changed every two years
Uranium is not used in biology.
Uranium is not used in medicines.
Uranium is not used in medicine.
1. Uranium is used as an explosive in fission bombs. 2. Uranium is not used in medicine.
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
- uranium is radioactive- uranium has 3 natural isotopes and many artificial isotopes- uranium is a solid metal- uranium is dense; 19,1 g/cm3- the atomic weight is 238,02891(3)- the atomic number is 92- the melting point is 1 0132,2 0C- the boiling point is 4 131 0C- uranium is paramagnetic- the covalent radius of uranium atom is 196+/-7 pm- the crystalline structure is orthorombic- uranium is used in nuclear fuels for nuclear reactors- depleted uranium can be used for armors and ammunition- uranium can be used in atomic bombs- etc.
uranium can be used as a thermal power source in nuclear power plants.one kilogram of uranium can produce energy equivalent 3000 kilograms of coal.but is also equally dangerous because of radiations from it
Uranium. A breeder reactor can use either Uranium, Plutonium, or mixed Transuranic elements for fuel. Depleted Uranium or Thorium is used as the breeding blanket. Periodically the breeding blanket is changed: the old one reprocessed to make new fuel.
Disadvantages of uranium: 1. Uranium is a possible polluting agent of the natural environment. 2. Uranium is a toxic and a radioactive chemical element. 3. Uranium release radium and radon. 4. Radioactive wastes are dangerous and need to be isolated.
