Title: Initiation of persistent fission chains in the fast burst reactor Caliban

Abstract

We provide in this article, experimental data of initiation of persistent fission chains obtained at different supercritical states, using the Fast Burst Reactor CALIBAN. In many past papers, theory has been compared mostly to initiation experiments at various super-prompt critical states, whereas very few experimental data has been published in delayed supercritical states. To fill the lack of data, we have conducted three campaigns on the reactor at reactivities far below 0.7$ which was one of the rare lowest state ever published on a similar assembly [2][1]. We give a justification of the use of the gamma function to fit experimental results of the temporal distributions of waiting times and compare experiments with numerical simulations obtained with a zero-D punctual Monte Carlo code.
