Nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series of these reactions. The specific nuclear reaction may be the fission of heavy isotopes (e.g., uranium-235, 235 U). The nuclear chain reaction releases several million times more energy per reaction than any ...

This advanced concept includes UzSi2 as a fuel and FeCrAl as a cladding material and moderated by light water. 8 mm in diameter fuel pellets are inserted inside cladding tube that 500 um thick.
Chat OnlineIn the scope of the CHANDA project of the European Commission a sensitivity and uncertainty analysis of the neutron multiplication factor [k.sub.eff] and the effective delayed neutron fraction [[beta].sub.eff] was performed to identify the most important nuclear data for neutron-induced reactions for criticality calculations of the latest MYRRHA designs.

Chat Online2.1.3 Infinite multiplication factor The infinite multiplication factor, since it assumes no leakage, may be expressed as absorption production k∞ = . The infinite multiplication factor also represents the average number of neutrons in a generation resulting from a single neutron in the preceding generation in an infinite reactor.

Chat OnlineEffective neutron multiplication factor The effective neutron multiplication factor , k , is the average number of neutrons from one fission that cause another fission. The remaining neutrons either are absorbed in non-fission reactions or leave the system without being absorbed.
Chat OnlineThis is known as the neutron multiplication factor, symbolized as k. In this example, k will always be two; however, in reality, there are many factors which change k, such as fuel enrichment and reactor design, which I shall futher explicate below.
Chat OnlineInfinite Multiplication Factor. In this section, the infinite multiplication factor, which describes all the possible events in the life of a neutron and effectively describes the state of an infinite multiplying system, will be defined. The required condition for a stable, self-sustained fission chain reaction in a multiplying system (in a nuclear reactor) is that exactly every fission ...
