Purpose Both Title 10 of the Code of Federal Regulations, Section 71.71 (10CFR71.71) and IAEA TS-R-1 specify the thermal conditions that a Type B transportation package has to survive for it to be certified by the US Nuclear Regulatory Commission or the IAEA. The normal conditions of transport are sometimes used to set the initial conditions for accident analysis. While the regulations are very clear in their requirements, they do not provide the methodology for applying the specified conditions. A standard practice document will answer questions related to the proper implementation of the different possible methods that exist for applying the NCT regulatory conditions to Type B packages. Therefore, it is proposed to develop a new section in E2230 that contains standard methods for evaluating these conditions and their implications on the package being analyzed. This new section will make E2230 more complete, since the current sections containing information on the NCT are limited and do not provide any guidance about how to apply these conditions.
