NaI detector nonlinearity for PGNAA applications
Abstract The nonlinearity of a 6″×6″ NaI detector used for PGNAA has been measured. The prompt γ-rays from pure element samples mixed with graphite were used for this determination in the range fromExpand
Steam Generator control in Nuclear Power Plants by water mass inventory
Abstract Control of water mass inventory in Nuclear Steam Generators is important to insure sufficient cooling of the nuclear reactor. Since downcomer water level is measurable, and a reasonableExpand
A study of the real-time deconvolution of digitized waveforms with pulse pile up for digital radiation spectroscopy
Two new real-time approaches have been developed and compared to the least-squares fit approach for the deconvolution of experimental waveforms with pile-up pulses. The single pulse shape chosen isExpand
Monte carlo aided treatments of the nonlinear inverse PGNAA measurement problem for various continuous on-line applications
A review of our work on the application of the PGNAA method as applied to five industrial applications is given. Some introductory material is first given on the importance and use of Monte CarloExpand
Coincidence counting for PGNAA applications: Is it the optimum method?
SummaryOne of the main advantages of γ-γ coincidence counting is the reduction of the background spectrum, pulse pile-up, and summing effects (for simple schemes). For prompt gamma-ray neutronExpand
Loose part monitoring system improvements
Abstract Metal impact theory, plate wave transmission theory, and experimental data were used to develop an analytical basis for loose part monitoring system performance. Valid signal properties wereExpand
Elemental PGNAA analysis using gamma–gamma coincidence counting with the library least-squares approach
Abstract An accurate method for determining elemental analysis using gamma–gamma coincidence counting is presented. To demonstrate the feasibility of this method for PGNAA, a system of threeExpand
Dynamic analysis of a pressurized water reactor
Time-domain correlation on bandwidth-limited time-series proved to be very valuable and could remove the misinterpretation of the frequency-domain analyses. Expand
Autoregressive moving average inverse dynamics for rhodium self-powered neutron detector
AbstractThe autoregressive moving average (ARMA) solution is derived for the rhodium self-powered neutron detector inverse dynamics. Numerical performance is compared to the autoregressive (AR)Expand
Loose parts signal theory
Abstract A loose parts signal model was developed using Hertz impact theory and equations for plate wave propagation, accelerometer response, and signal filtering. The detected signal frequencyExpand
