Before each shipment of licensed material, the licensee must ensure the package with its contents satisfies the applicable requirements of 180 NAC 13-015 and the licensee.

015.01 PROPER PACKAGING. The package is proper for the contents to be shipped.

015.02 UNIMPAIRED PHYSICAL CONDITION. The package is in unimpaired physical condition except for superficial defects such as marks or dents.

015.03 CLOSURE DEVICES. Each closure device of the packaging, including any required gasket, is properly installed and secured and free of defects.

015.04 LIQUIDS. Any system for containing liquid is adequately sealed and has adequate space or other specified provision for expansion of the liquid.

015.05 PRESSURE RELIEF DEVICES. Any pressure relief device is operable and set according to written procedures.

015.06 LOADING AND CLOSURE. The package has been loaded and closed according to written procedures.

015.07 MODERATORS AND NEUTRON ABSORBERS. For fissile material, any moderator or neutron absorber, if required, is present and in proper condition.

015.08 PACKAGE STRUCTURE REQUIREMENTS. Any structural part of the package that could be used to lift or tie down the package during transport is rendered inoperable for that purpose, unless it satisfies design requirements specified in 10 CFR 71.45;

015.09 PACKAGE EXTERNAL SURFACE LEVELS OF REMOVABLE RADIOACTIVE CONTAMINATION. The level of removable radioactive contamination on the external surfaces of each package offered for shipment is as low as reasonably achievable. The level of removable radioactive contamination may be determined by wiping an area of 300 cm2 of the surface concerned with an absorbent material, using moderate pressure, and measuring the activity on the wiping material. Sufficient measurements must be taken in the most appropriate locations to yield a representative assessment of the removable contamination levels. Except as provided in 180 NAC 13-015.09(A), the amount of radioactivity measured on any single wiping material, when averaged over the surface wiped, must not exceed the limits given in TABLE 13-3 of 180 NAC 13-015 at any time during transport. Other methods of assessment of equal or greater efficiency may be used. When other methods are used, the detection efficiency of the method used must be taken into account and in no case may the removable contamination on the external surfaces of the package exceed 10 times the limits listed in TABLE 13-3.

(A) In the case of packages transported as exclusive use shipments by rail or highway only, the removable radioactive contamination at any time during transport must not exceed 10 times the levels prescribed in 180 NAC 13-015.09. The levels at the beginning of transport must not exceed the levels in 180 NAC 13-015.09.

015.10 EXTERNAL RADIATION LEVELS AROUND THE PACKAGE AND AROUND THE VEHICLE. External radiation levels around the package and around the vehicle, if applicable, will not exceed 2 mSv/h (200 mrem/hr) at any point on the external surface of the package at any time during transportation. The transport index must not exceed 10.

015.11 EXCLUSIVE USE SHIPMENT. For a package transported in exclusive use by rail, highway or water:

(A) Radiation levels external to the package may exceed the limits specified in 180 NAC 13-015.09 but must not exceed any of the following:
(i) 2 mSv/h (200 mrem/hr) on the accessible external surface of the package unless the following conditions are met, in which case the limit is 10 mSv/h (1000 mrem/hr);
(1) The shipment is made in a closed transport vehicle;

(2) Provisions are made to secure the package so its position within the vehicle remains fixed during transportation; and

(3) There are no loading or unloading operations between the beginning and end of the transportation.

(ii) 2 mSv/h (200 mrem/hr) at any point on the outer surface of the vehicle, including the top and underside of the vehicle, or, in the case of a flatbed style vehicle, at any point on the vertical planes projected from the outer edges of the vehicle, on the upper surface of the load, or enclosure, if used, and on the lower external surface of the vehicle;

(iii)0.1 mSv/h (10 mrem/hr) at any point 2 meters from the vertical planes represented by the outer lateral surfaces of the vehicle, or, in the case of a flatbed style vehicle, at any point 2 meters from the vertical planes projected from the outer edges of the vehicle; and

(iv)0.02 mSv/h (2 mrem/hr) in any normally occupied positions of the vehicle, except this provision does not apply to private motor carriers when persons occupying these positions are provided with special health supervision, personnel radiation exposure monitoring devices, and training according to 180 NAC 10-003; and

(B) The shipper must provide specific written instructions to the carrier for maintenance of the exclusive use shipment controls. The instructions must be:
(i) Included with the shipping paper information; and

(ii) Sufficient so that, when followed, they will cause the carrier to avoid actions that will unnecessarily delay delivery or unnecessarily result in increased radiation levels or radiation exposures to transport workers or member of the general public.

015.12 ACCESSIBLE PACKAGE SURFACE TEMPERATURES. A package must be prepared for transport so that in still air at 100 degrees Fahrenheit (38 degrees Celsius) and in the shade, no accessible surface of a package would have a temperature exceeding 122 degrees Fahrenheit (50 degrees Celsius) in a nonexclusive use shipment or 185 degrees Fahrenheit (85 degrees Celsius) in an exclusive use shipment. Accessible package surface temperatures must not exceed these limits at any time during transportation.

015.13 CONTINUOUS VENTILATION. A package may not incorporate a feature intended to allow continuous venting during transport.
