Non Destructive

We designed a set of non-destructive system which is based on ray inspection systems, it mainly used to detect the Green Channel Cargo, and the result will be given out within 30 seconds. The ray coefficient of the Green Channel Cargo are different from the other transport cargo, so we can measure the absorption coefficient and compare it with the standard samples which is pre-built. The moved radioactive source and detector are designed, in order to prevent the mixed goods, we designed the removable radioactive sources and detectors, so the goods can be scanned up and down and around. Once the goods are mixed together, the ray coefficient which is calculated synchronously will be abnormal, parking and manual inspection is a supplementary means, so as to achieve a low-cost non-destructive testing.

Prompt Emission

Two models with a deterministic treatment of prompt emission in fission were developed at the University of Bucharest. Both models work with the same ranges of initial fragments and total kinetic energy and they use the same partition of the total excitation energy at full acceleration based on modelling at scission. The main difference between these modelings regards the prompt emission treatment itself. I.e. the Point-by-Point (PbP) model uses a global treatment of sequential emission while the other modeling is based on an event-by-event treatment of sequential emission. Both models are submitted to a rigorous validation. This paper focuses on model results of different prompt γ-ray quantities, which describe very well the existing experimental data. A new method to calculate prompt γ-ray spectra, including a global treatment based on the distribution of prompt γ-ray energy per quanta, is proposed.
