Delayed Neutron Group Parameters from Photofission
This dissertation presents a theoretical basis and the experimental procedure for the determination of delayed neutron group parameters resulting from photofission for three fissionable materials (238U, 232Th, and 239Pu).

Nuclear Principles in Engineering
Delayed neutron precursors Not all neutrons are released at the same time
following a fission event. Nearly 99% of all neutrons are released virtually
instantaneously (within about 10–13 s) after the actual fission event. These
neutrons are ...

Nuclear Reactor Physics
Moreover, for a transient below prompt critical, the largest part of the neutron
source is due to the decay of delayed neutron precursors, which tends to hold
back a flux tilt until the delayed neutron precursor distribution also tilts. The point

Nuclear Reactor Kinetics and Plant Control
1.3 Prompt Neutron and Delayed Neutron Most neutrons (99.35 % for 235U
fission by thermal neutrons) are emitted immediately by a nuclear fission event.
These are called “prompt neutrons.” A few neutrons are emitted a little after
nuclear ...

Here, however, we shall instead use the traditional derivation with the forward
and backward equations. In order to calculate the moments, a master equation
will be considered for the joint distribution of neutrons, one group of delayed

Imre Pazsit, Lenard Pal, 2007
The delayed neutron fraction, β, can be estimated from a zero-dimensional
neutronics calculation by weighting the delayed neutron fraction of each
fissionable isotope with the number of neutrons produced from fissions by that
isotope, ...

Reactor Dosimetry: Methods, Applications, and Standardization
The relation between the number of counts in a delayed neutron counter and the
neutron flux, *, based on the empirical Keepin [11] six- group representation of
the delayed neutron data is given by where e = efficiency of the detector, P =
