Abstract

Based on the probability balance of neutron random events in multiply system, the four random process of neutron in prompt super-critical is described and then the equation of neutron initiation probability W(r,E,{Omega},t) is deduced. On the assumption of static, slightly prompt super-critical and the two factorial approximation, the formula of the average probability of 'one' neutron is derived which is the same with the result derived from the point model. The MC simulation using point model is applied in Godiva- II and CFBR-II, and the simulation result of one neutron initiation is well consistent with the theory that the initiation probability of Godiva- II inverted commas CFBR-II burst reactor are 0.00032, 0.00027 respectively on the ordinary burst operation.

Monte Carlo Direct Simulation Method for Initiation Probability Problems

Journal Article Xu, Qi; Xiao, Gang; Wang, Xuerong - Transactions of the American Nuclear Society

During the early period of a supercritical system, the growth of fission chains shows a significant stochastic feature. In multiplying medium, it is a probability issue of fail-pass type for a single neutron to sponsor a divergent fission chain, and the probability of success is named as single neutron initiation probability. Meanwhile, in the presence of a weak neutron source, the time at which fission burst occurs also exhibits a stochastic nature, which can be observed on experiments of pulsed reactors such as GODIVA I and GODIVA II. The initiation probability and burst waiting time reflect the dynamic feature ofmore »« less
Burst wait time simulation of CALIBAN reactor at delayed super-critical state

Conference Humbert, P.; Authier, N.; Richard, B.; ...

In the past, the super prompt critical wait time probability distribution was measured on CALIBAN fast burst reactor [4]. Afterwards, these experiments were simulated with a very good agreement by solving the non-extinction probability equation [5]. Recently, the burst wait time probability distribution has been measured at CEA-Valduc on CALIBAN at different delayed super-critical states [6]. However, in the delayed super-critical case the non-extinction probability does not give access to the wait time distribution. In this case it is necessary to compute the time dependent evolution of the full neutron count number probability distribution. In this paper we present themore »« less
PROBABILITY DISTRIBUTION OF NEUTRONS AND PRECURSORS IN A MULTIPLYING ASSEMBLY

Technical Report Bell, G.

The probability distribution of the number of neutrons and delayed neutron precursors in a multiplying assembly is considered. Particular emphasis is placed on the probability distribution for a system which is brought to a supercritical state in the presence of a neutron source which is so weak that deviations from the average population may be large. A space independent model is used with one group of neutrons. The problem is formulated in terms of the probability distribution generating function which satisfies a partial differential equation, which is derived. Its solution is attempted by the method of characteristics and general propertiesmore »« less

Godiva IV Central Cavity Neutron Environment Characterization with Threshold Neutron Detectors

Conference Whitman, Nicholas; Pierson, Bruce; Weldon, Robert; ...

Godiva IV is a cylindrical fast burst reactor comprised of approximately 65 kg of highly enriched uranium that is operated by Los Alamos National Laboratory and sited at the National Criticality Experiments Research Center at the Nevada National Security Site in Nevada in the United States. Godiva IV is typically operated at delayed critical and in the regime spanning from sub-prompt to super-prompt bursts. Godiva IV is used for sample irradiations, criticality safety demonstrations, dosimetry studies, and for studying super-prompt behavior. In preparation for both an upcoming experiment to reduce uncertainties in the prompt fission spectrum for ²³⁵U using thresholdmore »« less

A Note on the Probability of Initiation Problem

Technical Report Chang, Britton

The purpose of this note is to draw attention to Pál for his derivation of the Pál-Bell equation which is used by LLNL and LANL to model Probability of Initiation (POI) problems. Both laboratories credit the equation to Bell and Lee. Although the equation formulated by Bell and Lee and the equation derived by Pál appear to be the same, the equation by Bell and Lee is flawed. Scattering, which was absent in Bell’s original formulation of a POI problem, was later introduced by Bell and Lee by replacing a fission term with a scattering term. Such a replacement, however,more »« less
