“…The STANDARD value of 0.05 represents a conservative average across a series of building types, including residential, office, and industrial structures (Engelmann, 1990). This value is about five times higher than the value for high-rise buildings with air-conditioning systems used by Finley et al, (1980) , 1977). This value applies to the sum of deposited activity over all radionuclides of a multi-radionuclide material.…”

“…may reasonably be expected to be found. For STREET, the sidewalk is modeled as being 3 m wide (Finley et al 1980). The values for WATER conservatively model a narrow navigable waterway (e.g., Houston Ship Channel) and are taken from NUREG-0170 (NRC, 1977).…”

This User Guide for the RADTRAN 5 computer code for transportation risk analysis describes basic risk concepts and provides the user with step-by-step directions for creating input files by means of either the RADDOG input file generator software or a text editor. It also contains information on how to interpret RADTRAN 5 output, how to obtain and use several types of important input data, and how to select appropriate analysis methods. Appendices include a glossary of terms, a listing of error messages, data-plotting information, images of RADDOG screens, and a table of all data in the internal radionuclide library. 4 AcknowledgmentThe authors thank Timothy Wheeler and Scott Mills for their thorough technical reviews and advice. We also wish to acknowledge the editorial and word processing support of Faith Puffer and Debra Rivard at Tech Reps, a division of Ktech Corporation.5

“…These consequences were considered unacceptable and the U.S. Nuclear Regulatory Commission promulgated very restrictive interim regulations (draft 10CFR73.37) to protect the public from such a malevolent act.

“…A "Second Urban Study" was performed by Finley et al in 1980 and resulted in a 14-fold reduction in the estimated release fraction for respirable aerosols (from 1% in the original Urban Study, to only 0.07%). Despite the improved analyses in the Second Urban Study, essentially no changes were made in the restrictive interim regulations on spent fuel shipments.…”

The Need for Confirmatory Experiments on the Radioactive Source Term from Potential Sabotage of Spent Nuclear Fuel Casks

A technical review is presented of experiment activities and state of knowledge on air-borne, radiation source terms resulting from explosive sabotage attacks on spent reactor fuel subassemblies in shielded casks. Current assumptions about the behavior of irradiated fuel are largely based on a limited number of experimental results involving unirradiated, depleted uranium dioxide "surrogate" fuel. The behavior of irradiated nuclear fuel subjected to explosive conditions could be different from the behavior of the surrogate fuel, depending on the assumptions made by the evaluator. Available data indicate that these potential differences could result in errors, and possible orders-of-magnitude overestimates of aerosol dispersion and potential health effects from sabotage attacks. Furthermore, it is suggested that the current assumptions used in arriving at existing regulations for the transportation and storage of spent fuel in the U.S. are overly conservative. This, in turn, has led to potentially higher-than-needed operating expenses for those activities.A confirmatory experimental program is needed to develop a realistic correlation between source terms of irradiated fuel and unirradiated fuel. The motivations for performing the confirmatory experimental program are also presented. 4 ACKNOWLEDGMENTS
