Benchmarking the Sandia Pulsed Reactor III cavity neutron spectrum for electronic parts calibration and testing

The SPR (Sandia Pulsed Reactor) III bare cavity spectrum and integral parameters have been determined with 24 measured spectrum sensor responses and an independent, detailed, transport calculation. This environment qualifies as a benchmark field for electronic parts testing. The measured SPR III cavity spectrum is characterized by a very smooth curve that predicts the measured activities with a standard deviation of 3.5% for the 24 sensors. Within the limitations of the computational model, the spectrum is also very close to that provided by MCNP (Monte Carlo Neutron Photon) calculations.<
