No: 08-0275\nDear Mr. Lazourenko:\nThis is in response to your August 1, 2008 letter requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 171-1 80) applicable to the transportation of\nClass 7 (radioactive) material by vessel. Your questions are summarized and answered as\nfollows:\nQ1. What is the maximum amount of fissile material contained solely within large fieight\ncontainers that may be carried on board a single vessel?\nAl. In accordance with Table IIIB of 5 176.704(d), there is no vessel criticality safety index\n(CSI) limit for large fieight containers.\nQ2. May a single vessel carry groups of packages and overpacks up to a total of 200 CSI &\nan unlimited amount of large freight containers provided the CSI limits for each large fieight\ncontainer are met?\nA2. Yes. A single vessel may carry any combination of packages, overpacks and large\nfreight containers containing fissile material, provided; (1) each large freight container, group\nof packages andlor overpacks satisfies the CSI limits and the separation distances specified in\nTable IIIB of 5 176.704; (2) the CSI limits for each large freight container, hold,\ncompartment and defined deck area are satisfied (see Table IIIB of 5 176.704); and, (3) the\ntotal CSI of all packages and overpacks on the vessel does not exceed 200 (see Table IIIB of\n!j 176.704). There is no vessel CSI limit for large freight containers (see Al).\n\n<<<PAGE 2>>>\n\nI apologize for any delay in responding to your inquiry. I trust these answers satisfy your\nrequest. If you have any further questions, please contact Mr. Rick Boyle of our Radioactive\nMaterials Transport division of our Office of Hazardous Materials Technology. Mr. Boyle\ncan be reached by phone at 202-366-2993 or by email at rick.boyleO,dot.~ov.\nSincerely,\nCharles Betts\nStandards Development\nof Hazardous Materials Standards\n\n<<<PAGE 3>>>\n\nATLANTIC RO-RO CARRIERS, INC.\n1051 BLOOMFIELD AVE.

For instance, could a single vessel carry 40 cylinders with CSI = 5 per cylinder plus 10 large\nfreight containers with CSI = 25 per container with appropriate stowage requirements.\nThanks in advance,\nRegards, M\nAndrei Lazourenko\nTraffic manager","truncated":false,"body_characters":3395}
