§1512.General License: Plutonium-Beryllium Special Form Material

NOTE: Former §1512 has moved to §1515 and §1516.

A.A general license is issued to any licensee of the department to transport fissile material in the form of plutonium-beryllium (Pu-Be) special form sealed sources, or to deliver Pu-Be sealed sources to a carrier for transport, if the material is shipped in accordance with this Section. This material need not be contained in a package that meets the standards of LAC 33:XV.1513; however, the material must be contained in a Type A package. The Type A package must also meet the U.S. DOT requirements of 49 CFR 173.417(a).

B.The general license applies only to a licensee who has a quality assurance program approved by the U.S. NRC as satisfying the provisions of 10 CFR Part 71, Subpart H.

C.The general license applies only when a package's contents:

1.contain no more than a Type A quantity of radioactive material; and
2.contain less than 1000 grams of plutonium, provided that plutonium-239, plutonium-241, or any combination of these radionuclides, constitutes less than 240 grams of the total quantity of plutonium in the package.

D.The general license applies only to packages labeled with a CSI that:

1.has been determined in accordance with Subsection E of this Section;
2.has a value less than or equal to 100; and
3.for a shipment of multiple packages containing Pu-Be sealed sources, the sum of the CSIs is less than or equal to 50, for shipment on a nonexclusive use conveyance, or less than or equal to 100, for shipment on an exclusive use conveyance.

E.The following requirements must be met when determining the CSI.

1.The value for the CSI must be greater than or equal to the number calculated by the following equation.

2.The calculated CSI must be rounded up to the first decimal place.

§1513.External Radiation Standards for all Packages

NOTE: Former §1513 has moved to §1517.

A.Except as provided in Subsection B of this Section, each package of radioactive materials offered for transportation must be designed and prepared for shipment so that under conditions normally incident to transportation the radiation level does not exceed 2 mSv/h (200 mrem/h) at any point on the external surface of the package, and the transport index does not exceed 10.

B.A package that exceeds the radiation level limits specified in Subsection A of this Section must be transported by exclusive use shipment only, and the radiation levels for such shipment must not exceed the following during transportation:

1.2 mSv/h (200 mrem/h) on the external surface of the package, unless the following conditions are met, in which case the limit is 10 mSv/h (1000 mrem/h):
a.the shipment is made in a closed transport vehicle;
b.the package is secured within the vehicle so that its position remains fixed during transportation; and
c.there are no loading or unloading operations between the beginning and end of the transportation;
2.2 mSv/h (200 mrem/h) at any point on the outer surface of the vehicle, including the top and underside of the vehicle, or, in the case of a flat-bed style vehicle, at any point on the vertical planes projecting 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; and
3.0.1 mSv/h (10 mrem/h) at any point 2 meters (80 inches) from the outer lateral surfaces of the vehicle (excluding the top and underside of the vehicle), or, in the case of a flat-bed style vehicle, at any point 2 meters (6.6 feet) from the vertical planes projecting from the outer edges of the vehicle (excluding the top and underside of the vehicle); and
4.0.02 mSv/h (2 mrem/h) in any normally occupied space, except that this provision does not apply to private carriers, if exposed personnel under their control wear radiation dosimetry devices in accordance with LAC 33:XV.431.

C.For shipments made under the provisions of Subsection B of this Section, the shipper shall provide specific written instructions to the carrier for maintenance of the exclusive use shipment controls. The instructions must be included with the shipping paper information.
