The Measurement of Parameters of Zero Power Experiments Based on MNSR

Zero Power Experiments has been carried out on MNSR (Miniature Neutron Source Reactor) Zero Power Facility. The critical experiment was carried out by using elements method and 5 sets equipments to determine the critical load of the LEU (Low Enrichment Uranium) core; Meanwhile, the value of crucial parts was measured, these values includes the value of radial elements, the integration and differentiation value of central control rod and the value of upper Beryllium reflector. The measure result was precise and that provide a data support for the load of the LEU core and the Start-Up experiments on prototype MNSR.
