Description
Fast neutron hodoscope system as the main fuel motion diagnostic system in the Safety Engineering Reactor for Accident Phenomenology (SERAPH) was studied in order to realize high-resolution diagnostics for fuel density variation according to fuel motion. Based on the study on minimization of the detector size and improvement for the detector sensitivity, optimized concept of the detector design was proposed. On the other hand, geometry of the collimator and slot system was also optimized through the evaluation of optical conditions. Using the optimized design of the detector, collimator, and slot system, diagnostic performance for main SERAPH tests (single pin test, pin bundle test and molten fuel pool test, etc.) were quantified. It was confirmed that proposed system has sufficient diagnostic capability required in the SERAPH tests. (author)
