Spent nuclear fuel - Wikipedia
Spent nuclear fuel contains 3% by mass of 235 U and 239 Pu (also indirect products in the decay chain); these are considered radioactive waste or may be separated further for various industrial and medical uses.
Composition of Spent Nuclear Fuel | nuclear-power.com
Spent nuclear fuel, also called the used nuclear fuel, is a nuclear fuel that has been irradiated in a nuclear reactor (usually at a nuclear power plant or an experimental reactor), and a fresh fuel must replace that due to its insufficient reactivity.
Commercial reactor fuel is composed of small (approximately the size of a fingertip) ceramic pellets of uranium dioxide sealed inside 12- to 15-foot-long (3.7- to 4.6-meter-long) metal tubes, referred to as cladding, to form fuel rods. Typically the cladding material is zirconium alloy.
Spent Nuclear Fuel | Definition & Characteristics - nuclear …
Spent nuclear fuel, also called the used nuclear fuel, is a nuclear fuel that has been irradiated in a nuclear reactor (usually at a nuclear power plant or an experimental reactor), and a fresh fuel must replace that due to its insufficient reactivity.
Spent nuclear fuel from power reactors is unloaded into a water-filled pool immediately adjacent to the reactor to allow its heat and radiation levels to decrease. It is held in these pools for periods ranging from a few years to decades.
Spent fuel composition - radioactivity.eu.com
Key figures on spent fuel composition. The composition of irradiated fuel removed from a reactor core depends on the initial quantity of fissile material and the energy removed from it.
Nuclear Energy Agency (NEA) - SFCOMPO 2.0 (Spent Fuel Isotopic Composition)
SFCOMPO 2.0, Spent Fuel Isotopic Composition, is a relational database designed to facilitate the search and visualisation of experimental assay data of spent nuclear fuel. It allows the user to access, plot and export isotopic composition data, reactor operational histories and relevant design data relating to spent fuel samples.
Spent Nuclear Fuel - an overview | ScienceDirect Topics
The composition of spent nuclear fuel depends on the fission energy generated within the fuel assembly during irradiation in the nuclear reactor. Burn-up, usually expressed in megawatt-days/tonne of initial uranium, is a measure of the total energy produced by a fuel assembly.
Spent nuclear fuel - Energy Education
Spent fuel are the fuel bundles that can no longer sustain fission in a nuclear reactor. This happens because having fission daughter products make it too hard to keep the nuclear chain reaction going.
What Is Spent Nuclear Fuel? | NRC.gov
The Nuclear Regulatory Commission's Science 101: What is Spent Nuclear Fuel? You know how a nuclear power plant uses nuclear fuel and chain reactions to produce electricity. So what happens to that fuel when it's removed from a reactor?
