Fission Multiplicity Distribution Sampling in MCNP6 Criticality Calculations
… to the average number of neutrons emitted in fission of the system. It can be shown that if the average number of neutrons emitted in fission and the average neutron energy spectrum is conserved, the criticality of a system remains the same without regard to the actual physical fission …

Advances in the Theory of Persistent Neutron Chains
… associated with the Markov process of nuclear fission. For half a century, this problem has been solved by truncating fission multiplicities at two, an action known to reduce accuracy for both uranium and plutonium, which typically release between two and three neutrons per fission on average, …

Eigenfunction expansion of the time and space-dependent neutron survival probability equation
… system, and the number of factorial moments of fission multiplicity preserved in the equation. A steady-state diffusion equation is then solved semi-analytically in a one-dimensional slab, expanding understanding of the behavior of the survival probability and providing a benchmark for other …

A NEW MEASUREMENT OF THE NEUTRON MULTIPLICITY EMITTED IN 252Cf SPONTANEOUS FISSION
… used to make a new measurement on the neutron multiplicity probability distribution emitted during spontaneous fissions, with an average multiplicity of 3.81 ± 0.05 neutrons per fission.
