For low enriched uranium fuel working on a thermal neutron spectrum, the difference between the average and effective delayed neutron fractions can reach 50 pcm ( 1 pcm = 1e-5 ).
42.
Nevertheless, the delayed neutrons emitted by neutron-rich fission products aid control of nuclear reactors by making reactivity change far more slowly than it would if it were controlled by prompt neutrons alone.
43.
These fission products are important to the operation of the reactor because some fission products contribute delayed neutrons that are useful for reactor control while others are neutron poisons that tend to inhibit the nuclear reaction.
44.
The fission products which produce delayed neutrons have half lives for their dollars " and the prompt critical point is " one dollar ", and other points in the process interpolated in cents.
45.
Thus, by widening the margins of non-operation and supercriticality and allowing more time to regulate the reactor, the delayed neutrons are essential to inherent reactor safety and even in reactors requiring active control.
46.
Another concept, is the " effective fraction of delayed neutrons ", which is the fraction of delayed neutrons weighted ( over space, energy, and angle ) on the adjoint neutron flux.
47.
Another concept, is the " effective fraction of delayed neutrons ", which is the fraction of delayed neutrons weighted ( over space, energy, and angle ) on the adjoint neutron flux.
48.
Filippone maintains that when steam is used as the moderator, the average neutron energy is increased from that of a liquid water-moderated reactor such that the delayed neutrons persist until they hit another nucleus.
49.
Thus the time between successive generations of the reaction, " T ", is dominated by the time it takes for the delayed neutrons to be released, on the order of seconds or minutes.
50.
The relatively slow timescale on which delayed neutrons appear is an important aspect for the design of nuclear reactors, as it allows the reactor power level to be controlled via the gradual, mechanical movement of control rods.
