Section 180-13-011 - GENERAL LICENSE: FISSILE MATERIAL011.01GENERAL LICENSE ISSUANCE. A general license is issued to any licensee to transport fissile material, or to deliver fissile material to a carrier for transport, if the material is shipped according to 180 NAC 13-011. The fissile material need not be contained in a package which meets the standards of 10 CFR 71 subparts E and F; however the material must be contained in a Type A package that meets the DOT requirements of 49 CFR 173.417(a).011.02QUALITY ASSURANCE PROGRAM. The general license applies only to a licensee who has a quality assurance program approved by the Department.011.03PACKAGE CONTENTS. The general license applies only when a package's contents contain less than: (A) A Type A quantity of fissile material; and(B) 500 total grams of beryllium, graphite, or hydrogenous material enriched in deuterium.011.04CSl LABELING. The general license applies only to packages containing fissile material labeled with a CSI which: (A) Has been determined according to 180 NAC 13-011.05;(B) Has a value less than or equal to 10; and(C) For a shipment of multiple packages containing fissile material, the sum of the CSIs must be less than or equal to 50 for shipment on a nonexclusive use conveyance, and less than or equal to 100 for shipment on an exclusive use conveyance.011.05CRITICALITY SAFETY INDEX (CSI) DETERMINATION. This section addresses how to determine the CSI of fissile material. (A) The value for the CSI must be greater than or equal to the number calculated by the following equation: Click here to view
The calculated CSI must be rounded up to the first decimal place;
(B) Values of X, Y, and Z used in the Index CSI equation must be taken from Table 13-1 or Table 13-2, as appropriate;(C) If Table 13-2 is used to obtain the value of X, then the values for the terms in the equation for uranium-233 and plutonium must be assumed to be zero; and(D) Table 13-1 values for X, Y, and Z must be used to determine the CSI if: (i) Uranium-233 is present in the package;(ii) The mass of the plutonium exceeds 1% of the mass of uranium-235;(iii) The uranium is of unknown uranium-235 enrichment or greater than 24 weight percent enrichment; or(iv) Substances having a moderating effectiveness, that is, an average hydrogen density greater than H2O, certain hydrocarbon oils or plastics, are present in any form, except as polyethylene used for packing or wrapping. TABLE 13-1
Mass Limits for General License Packages Containing Mixed Quantities of Fissile Material or Uranium-235 of Unknown Enrichment per 180 NAC 13-011.05.
Fissile material | Fissile material mass mixed with moderating substances having an average hydrogen density less than or equal to H2O (grams) | Fissile material mass mixed with moderating substances having an average hydrogen density greater than H2Oa (grams) |
235U (X) | 60 | 38 |
233U (Y) | 43 | 27 |
239Pu or241Pu (Z) | 37 | 24 |
a When mixtures of moderating substances are present, the lower mass limits must be used if more than 15% of the moderating substance has an average hydrogen density greater than H2O.
