RDW 5.6 O MINOR Revision 2 04-06-84 MARKING AND LABELING REQUIREMENTS FOR SHIPMENTS OF RADIOACTIVE MATERIAL PACKAGES 1.0 GENERAL Marking and labeling of radioactive material packages is specified under the Department of Transportation regulations. The following terminology refers to the specific requirements that must be fulfilled prior to shipment.

2.0 REFERENCES

2.1 49 CFR Parts 100 to 199, Transportation 2.2 HPSO 10, Use of Radiation Measurement Instruments for Radioactive Material Package Surveys 3.0 MARKING (49 CFR 172.300) -

3.1 Each package containing radioactive material for transportation shall A be marked with the applicable shipping name unless exception is

(,

granted by regulation.

3.2 All marking must be durable and printed on or affixed to the surface of a package or printed on a label, tag, or sign attached to the package. Marking must be of a sharply contrasting color and must not be obscured and must be located away from other marking that could reduce its effectiveness. Abbreviations may not be used unless specifically authorized by this procedure or by 49 CFR.

3.3 Each package of radioactive material offered for shipment must be l marked as follows. (49 CFR 172.310) i

! 3.3.1 Packages in excess of 110 pounds must have the gross weight marked on the outside.

3.3.2 Packages conforming to Type A or Type B packaging must be marked with the words " Type A" or " Type B" in letters at least "

in height. In addition, Type A packages must be marked

" USA DOT 7A" in letters at least \" high. (49 CFR 178.350-3) 3.4 Each package of radioactive waste must be marked as Class A Waste, Class B Waste, or Class C Waste. See RDW 3.8 (10 CFR 20.311(d)(2) and 61.57). These markings should be placed on the top and on two opposite sides of each package within 6" of the other DOT markings and labels.

In addition, unless directed otherwise by the NPS or Engineer assigned l to radwaste, each Class A marking must have the word " UNSTABLE" l marked adjacent to it. l l All lettering must be at least \" in height. l 3.5 Packages of radioactive material that are transported via a non-exclusive use vehicle will be marked with the name and address of Point Beach Nuclear Plant or the consignee. Exempt quantities need not meet this requirement (49 CFR 172.306).

3.6 As of July 1, 1983, packages of 110 gallons or less capacity must be marked with the DOT identification number corresponding to the shipping name marked on the package (49 CFR 172.301).

3.6.1 Shipping names and DOT identification numbers commonly used at Point Beach Nuclear Plant are below:

i Radioactive Material, n.o.s. UN 2982 Radioactive Material, LSA, n.o.s. UN 2912 Radioactive Material, Instrument & Articles UN 2911 4

Radioactive Material, Limited Quantity, n.o.s. UN 2910 Radioactive Material, Special form, n.o.s. UN 2974 Radioactive Material, empty packages UN 2908 3.6.2 A list of all shipping names and their associated identification numbers is found in the Hazardous Materials Table, 49 CFR 172.101.

3.7 Limited Quantities Limited quantities of radioactive materials and radioactive devices are not required to have any markings or labels on the outside container, provided there is an inside packaging that is marked

" Radioactive."

, Refer'to RDW 5.2 for details.

4.0 LABELING (49 CFR 172.400) 4.1 Unless exempted from labeling by regulation such as limited quantity or exclusive use vehicle shipments of no greater than Type A quantities of LSA materiil, each package of radioactive material offered for j shipment must be labeled as one of the following.

RDW 5.6 A Page 3 4.1.1 Radioactive White I Label This label will be used for packages meeting the following requirements:

a. Measures less than 0.5 mrem / hour at any point on the external surface of the package.
b. Does not contain Fissile Class II or III radioactive material.
c. Does not contain a " highway route controlled quantity" of radioactive material.

. 4.1.2 Radioactive Yellow II This label will be used for packages meeting the following requirements:

, a. Measures more than 0.5 mrem / hour but not more than 50 mrem / hour at any point on the surface of the package.

, f b. Does not exceed one mrem / hour at any point one meter (3.3 feet) from the external surface of the package;

~

i.e., transport index 51.0.

c. Meets the requirements for Fissile Class II package having a transport index of one or less.
d. Does not contain a " highway route controlled quantity" of radioactive material.

4.1.3 Radioactive Yellow III l

j This label will be used for packages meeting any of the following requirements:

a. Measures more than 50 mrem / hour at any point on the surface of the package.

i b. Exceeds one mrem / hour at any point one meter (3.3 feet) l from the external surface of the package.

c. Meets the requirements for Fissile Class.III package.

l L d. Contains a " highway route controlled quantity" of l radioactive material.

RDW 5.6 Page 4 4.1.4 Measurement and records of radiation levels should be to the nearest .1 mR/ hour for readings less than 2.0 mR/ hour, to the nearest 1 mR/ hour for readings up to 11 mR/ hour, to the nearest 5 mR/ hour up to 55 mR/ hour, and to at most two significant figures above 55 mR/ hour. It is especially important for packages with low radiation levels that the background radiation be subtracted off in order to obtain the net radiation reading.

4.2 Packages of radioactive material which also meet the definition of an additional hazard class must be labeled to reflect the additional hazard. (49 CFR 172.402) Refer to 49 CFR 173.2 for hazard, class listing and exceptions.

4.3 The following information must be entered on the RADIOACTIVE label chosen in Section 4.1 by printing, using a durable weather resistant marking.

4.3.1 Contents For mixtures of radionuclidec the most restrictive radio-nuclides on the basis of radiotoxicity must be listed as space on the label allows. Abbreviated symbols such as Co-60, Cs-137 are authorized.

4.3.2 Activity

. Enter the total activity of the package in Curies.

4.3.3 Transportation Index Enter the highest dose rate measurement at one meter (3.3 feet) from the external surface of the package. (Not l recorded on White - I labels.)

l NOTE: ALL ENTRIES ARE TO BE MADE WITH INDELIBLE INK. A " SHARPIE" j PEN IS SUITABLE. [49 CFR 172.403(g)]

5.0 PLACEMENT OF LABELS ON PACKAGE (49 CFR 172.406) l l The following specifies the manner in which labels will be printed or affixed to the surface of the package. -

! 5.1 Labels must be displayed on at least two sides or two ends of each l package of radioactive material. .

l 5.2 Vehicle placarding may not be used in lieu of package labeling. ,

l 5.3 One of each of the appropriate labels must be displayed on or near l

the package closure.

. . RDW 5.6 A Page 5 5.4 Labels must not be obscured by markings or attachments.

~ 5.5 Labels must be durable, weather resistant and constructed in accordance with 49 CFR 172.407.

6.0 OVERPACKS [49 CFR 173.448(g)]

6.1 Packages of radioactive material transported in an overpack must comply with all packaging, marking and labeling requirements as if no overpack was used.

6.2 The overpack must also be marked and labeled. [49 CFR 173.25]

6.2.1 Markings will include all applicable proper shipping names.

An overpack can have more than one shipping name marked on it.

6.2.2 The overpack must be marked "INSIDE PACKAGES COMPLY WITH PRESCRIBED REGULATIONS."

6.2.3 Overpacks containing only LSA or limited quantities or a mixture of both need not be marked as specified in Section 6.2.2.

4 6.2.4 The overpack must be labeled as per Section 4.0 above.

However, the label entries are determined as follows:

a. The " contents" entre a the label may state " mixed" unless each inside package contains the same radio-nuclide(s).
b. The number of curies is determined by adding together the Curies of each package in the overpack.
c. The transport index is determined by direct measurement of the overpack dose rate at one meter (3.3 feet) from the surface unless the overpack contains fissile material.
d. If the overpack contains fissile material, the transport index is determined by adding together the transport indices of the packages contained inside.

6.2.5 The transport index of an overpack is limited by the mode of transport as listed below:

Transport Mode TransportIndexLihit Passenger Aircraft 3.0 Cargo Only Aircraft 10.0 l ( "

Nonexclusive Use Vehicle 50.0

7.0 EMPTY PACKAGING (49 CFR 173.427)

Any packaging which previously contained radioactive materials and has been emptied of its contents as far as practical, is excepted from marking and labeling requirements of 49 CFR and from all requirements in 49 CFR, Subpart I, except for paragraph 173.427(b), (c), (e), if the following conditions are met:

7.1 The radiation levei at any point on the external surface of the packaging does not exceed 0.5 mrem / hour.

7.2 The removable radioactive contamination on the external surface of the packaging does not exceed the limits specified in RDW 5.7, Section 5.

7.3 The package does not contain more than 15 grams of Uranium-235.

7.4 The packaging is in unimpaired condition and is securely closed so that there'will be no leakage of radioactive material under conditidas normally incident to travel.

7.5 Internal contamination does not exceed the following:

Maximum Pernissible Level Contaminant (dpm/100 cm2)

Beta gamma emitting nuclides 2,200,000 All radionuclides with half-lives less than 10 days 2,200,000 Natura'l Uranium, Natural Thorium, Uranium-235, Uranium-238, Thorium-228, and Thoritan-230, when contained in ores or physical concentrates 2,200,000 Alpha (other than noted above) 220,000 7.6 All previous DOT labels must be removed and " Empty" labels affixed to

two opposite sides of the packaging. The label must be white with black lettering. (49 CFR 172.450)
