Exempel på hur du använder FISSILE i en mening

• When a fissile nucleus like uranium-235 or plutonium-239 absorbs a neutron, it splits into lighter nuclei, releasing energy, gamma radiation, and free neutrons, which can induce further fission in a self-sustaining chain reaction.
• The term shale is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile mudrock.
• Uranium-235 fissions with low-energy thermal neutrons because the binding energy resulting from the absorption of a neutron is greater than the critical energy required for fission; therefore uranium-235 is fissile.
• These thermal neutrons are immensely more susceptible than fast neutrons to propagate a nuclear chain reaction of uranium-235 or other fissile isotope by colliding with their atomic nucleus.
• A light water reactor (LWR) uses water in the form that occurs in nature, and requires fuel enriched to higher concentrations of fissile isotopes.
• Mixed oxide fuel, commonly referred to as MOX fuel, is nuclear fuel that contains more than one oxide of fissile material, usually consisting of plutonium blended with natural uranium, reprocessed uranium, or depleted uranium.
• The fission warhead was a linear implosion type, consisting of a long cylinder of subcritical fissile material which is compressed and shaped by explosive into a supercritical sphere.
• This irradiated fertile material in turn transmutes into fissile material which can undergo fission reactions.
• In any reactor, a scram is achieved by inserting large amounts of negative reactivity mass into the midst of the fissile material, to immediately terminate the fission reaction.
• However, it is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239.
• These group focused on: negotiating a treaty banning the production of fissile material for nuclear weapons (FMCT), creating practical steps to reduce nuclear weapons, Prevention of an Arms Race in Outer Space (PAROS) and addressing negative security assurances.
• At Princeton, Wilson eventually took over Smyth's project of the development of an alternative approach to electromagnetic separation from Lawrence's calutron method, used for the purpose of separating the fissile uranium-235 isotope of uranium from the much more common uranium-238, which is a key step to producing an atomic bomb.
• The service chiefs insisted on a yield of between 10-12 kt for two reasons: firstly, to minimise usage of scarce and expensive fissile material; and secondly, to minimise the risk of predetonation, a phenomenon then little understood, and the primary reason for using a composite core of concentric shells of plutonium and U-235.
• Thorium is not fissile (but is "fertile", breeding fissile uranium-233 under neutron bombardment); hence, it must be used as a nuclear reactor fuel in conjunction with fissile isotopes of either uranium or plutonium.
• Breeding refers to nuclear transmutations that produce fuel for further reactions, in a breeder reactor to become fissile material or in a fusion reactor to produce tritium, see.
• Thorium nuclei absorb neutrons, thus breeding fissile uranium-233, an isotope of uranium which is not found in nature.
• A neutron reflector can make an otherwise subcritical mass of fissile material critical, or increase the amount of nuclear fission that a critical or supercritical mass will undergo.
• Where fissile materials are handled in civil and military installations, specially trained personnel are employed to carry out such calculations and ensure that all reasonably practicable measures are used to prevent criticality accidents, during both planned normal operations and any potential process upset conditions that cannot be dismissed on the basis of negligible likelihoods (reasonably foreseeable accidents).
• If the organic layer was to acquire too much metal then a solid metal complex might form, or more worryingly in a nuclear process the potential for a criticality accident if the fissile metal concentration in the organic phase becomes too high.
• The light-water reactor (LWR) is a type of thermal-neutron reactor that uses normal water, as opposed to heavy water, as both its coolant and neutron moderator; furthermore a solid form of fissile elements is used as fuel.
