Title:
燃料集合体放射能測定装置および燃料集合体の放射能測定方法
Document Type and Number:
Japanese Patent JP5476274
Kind Code:
B2
Abstract:
A fuel assembly radiation measuring apparatus has a radiation signal generation apparatus including a LaBr3(Ce) scintillator, an A/D converter, a signal processing apparatus, and a data analysis apparatus. The signal processing apparatus has a FPGA and a CPU. γ rays emitted from a fuel assembly disposed in water in a fuel pool enter into the LaBr3(Ce) scintillator that emits scintillator light, then a photomultiplier tube converts the light into an electric signal as a radiation detection signal. A pulse height analyzer of the FPGA inputs a radiation detection signal having a digital waveform generated by the A/D converter and changes the digital waveform into a trapezoid waveform to obtain a maximum peak value. The data analysis apparatus quantifies a target nuclide using a plurality of inputted maximum peak values to obtain burnup.
