Overview of Proposed Modifications for Exemptions to the Requirements for Transport of Fissile Material - Presentation

Currently, transport of fissile material using TS-R-1 performed consistent with one of two sets of provisions: Set 1: Fissile material in packagings subject to CA design approval and CSI control of accumulation (2009 paras 671-683) Set 3: Fissile material excepted from all requirements of Set I if specified characteristics and limits are met (2009 para 417). Traditional “fissile-excepted” • Concerns expressed: • Safety: Insufficient control for accumulation of fissile material under Set 3 • Accuracy: Some Set 3 material should be classified as UN FISSILE • Transport of low-risk material under Set 1 (regulatory burden)
