Progress Report on Fast Breeder Reactor Safety Studies

Abstract

A proposal was made to ANL for NRL to construct a gamma ray pin-hole camera to follow the flow of molten fuel elements by observing the emitted gamma rays with a TV chain viewing an image of the fuel elements on a NaI screen. However, an alternative system has been proposed that will give the same space resolution, improved time resolution and dynamic range with greater flexibility and reduced cost. This system consists of a rotating cylinder with a large number of small collimating holes scanning across the test section. Signals from scintillation detectors placed behind the drum will intensity modulate the Z axis of multi-gun oscilloscopes, A continuously moving film camera will record these sweeps for study and analysis.
