Abstract or Summary
  • The Department of Nuclear Engineering at Oregon State University has recently introduced a neutron radiography facility (OSNRF). The facility is dependent on a neutron source established by the OSU TRIGA® Reactor (OSTR). It was unknown how accurately a computerized model of the OSTR in conjunction with the OSNRF could represent the radioactivity dose rate of the facility. Having an accurate model of the OSTR and OSNRF would save time and money in preparation of other future additions. The model was created using the Monte-Carlo N-Particle (MCNP) transport code. A retained model of the OSTR was modified to account for the addition of the neutron radiography facility and dose rates within the OSNRF were predicted. To determine the accuracy of the model, measured data was compared to predicted data from the MCNP simulation. The results show that MCNP consistently overestimates the neutron dose rate throughout the OSNRF. Gamma dose rates are consistently overestimated outside the beam line, but are underestimated within the beam line. It is determined that while the reliability of the predicted data is limited, potential exists for the model.
