Abstract

The primary purpose of the Multispectral Nuclear Logging project is to assess the effectiveness of applying nuclear borehole-logging techniques to the Department of Energy's (DOE) Environmental Restoration (ER) program, adapt the technology to improve these capabilities, and transfer that technology to industry. The purpose of the Monte Carlo simulations using MCNP is to predict the minimum concentration levels for environmental contaminants that could be detected by Multispectral Logging (MSL). The Monte Carlo code used for this type of simulation, MCNP, should be benchmarked against experimental data to show that the user can accurately reproduce the proper gamma-ray spectrum. Experimental data was obtained from Westinghouse-Hanford Company using the Environmental Measurements Corp. (EMC) logging tool in the Upper Barren Zone (UBZ) and Ore Zone (OZ) calibration models at Grand Junction. This paper continues the discussion of benchmarking MCNP using the UBZ and OZ data.
