RDW 5.7 MINOR f Revision 1 12-08-83

-- VEHICLE LOADING, SURVEYS AND PLACARDING PROCEDURES FOR SHIPMENTS OF RADIOACTIVE MATERIAL 1.0 GENERAL This procedure provides direction and guidelines for the loading, surveying, and placarding of vehicles carrying radioactive materials either arriving at or departing from PBNP.

2.0 REFERENCES

2.1 49 CFR Parts 100 to 199, Transportation 2.2 RDW 4.1, Receipt of Radioactive Material 2.3 RDW 5.9, Documentation of Shipping Packages 2.4 Letter, dated January 22, 1982, from C. W. Fay to H. G.

(

3.1 Empty v,ehi'cles arriving onsite to pick up shipments of radioactive material must be surveyed prior to loading. Except as noted in paragraph 3.2 below, the radiation dose rate at each accessible surface of the vehicle must not exceed 0.5 mrem / hour and the removable contamination levels must not exceed the limits specified in Section 5.0 below. Report the survey results to the supervisor in charge of the shipment prior to loading.

3.2 In certain situations, it is permissible to exceed the limits specified

in Section 3.1 above. If the vehicle is kept closed except during loading and unloading and if the exterior on both sides of the vehicle is conspicuously stenciled with the words "FOR RADIOACTIVE MATERIALS USE ONLY" in letters at least 76 millimeters (3"), then the following limits are applicable

3.3 Visually inspect the condition of the vehicle tires, wheels, flooring,

~~

welds and support beams. Report any leaks, cracks, or deterioration to the supervisor in charge of the shipment.

4.0 CARGO LOADING 4 4.1 Package Inspection j 4.1.1 All packages used to transport radioactive material with 4 activity exceeding 2.0E-9 Ci/g (9.1E-1 pCi/lb.) will be i inspected by a CHP Supervisor or a person designated by him.

4.1.2 Packages will normally receive two inspections.

a. The first inspection should be done within five working days of the shipment and will be documented on the checkoff of form CHP-78. This inspection is intended to be the primary assurance that the package is properly prepared for shipment.
b. The second inspection will be a visual check at the time
the package is leaded. This will assure that no deteri-oration of the package has occurred since the first

. inspection. The second inspection will be documented by L signing off the bottom of form CHP-78.

c. If no inspection document is required by procedure

!' RDW 5.9, form CKP-78 (Package Inspection Checkoff) will not be used. The first inspection requirement is also waivad. However, the visual check must be performed. A

, Health Physics Supervisor or Nuclear Plant Specialist

! (or Engineer) will approve the package for shipment. If

, it meets the criteria of a strong tight container, it may be shipped. In this case, the signature of the Supervisor or Nuclear Plant Specialist (or Engineer) on CHP-11, Radioactive Haterial Shipment Form, will be i evidence that the package was properly inspected.

J.

4.1.3 Casks will be inspected in accordance with their. applicable cask checkoff forms when the vehicle arrives on site.

4.2 Pallet Inspection

! 4.2.1 If packages are shipped on pallets, the supervis,or loading the truck shall assure that:

l a. Package is securely banded or otherwise attached to the pallet.

\#% b. The pallet is strong enough to support the package i during the trip.

I

RDW5.i Page 3 4.2.2 Drums weighing 2800 lbs., which are destined for the

.. Barnwell, SC, disposal site, must be palletized.

4.2.3 Drums weighting between 600 and 800 lbs, which are sent to Barnwell, SC, must be palletized only if they are shipped in a fixed top trailer.

4.2.4 Drums shipped to Richland, WA, need not be palletized.

4.2.5 A pallet should have two or more drums on it.

4.2.6 Drums should be banded to the pallet as follows:

a. One band over top of each drum.
b. Two bands around the drums.

4.3 Bracing the Load (49 CFR 173.448) 4.3.1 Sufficient bracing shall be used to prevent movement of the packages during conditions normally incident to transport (bouncing, swaying, sliding, etc.).

/ \ 4.3.2 The supervisor in charge of loading should inspect the

\s_,/ ,

bracing before shipment.

4.3.3 Palletized drums should be placed against walls or other secure drums if possible. Drum braces should be used to secure a pallet if the traile'r walls and other drums cannot be used to surround it.

4.4 Radiation Surveys During Loading When more than one package is to be shipped, and when the packages have contact readings in excess of 50 mR/ hour, the truck should be surveyed as the packages are loaded. If the limits in Section 6.0

(

below are exceeded, the load should be changed to meet the limits.

l l 4.5 Weight of Load

4.5.1 Check with the carrier to assure that the weight of the i packages does not exceed the vehicle's capacity.

4.5.2 Authorized weights for casks can be found in file HP 2.6.

RDW 5.7 Page 4 t-5.0_ RIMOVABLE RADIOACTIVE CONTAMINATION (49 CFR 173.443) 5.1 Contamination Control -

5.1.1 Whenever practical, locate vehicles to be loaded outside the controlled zone.

, 5.1.2 For vehicles that are brought into the controlled zone, establish a stepoff pad for the truck. The truck will be treated as a clean area. As a minimum, all personnel working on the truck surfaces will change into clean shoe covers.

5.1.3 A stepoff pad may also be established for vehicles loaded while located outside the controlled zone to provide convenient access. However, except for activities necessary for loading the transport vehicle, all personnel must still enter and leave the controlled zone in the normal manner.

5.2 Procedure i

l The level of removable contamination may be determined by wiping an area of 100 cm2 of the package or vehicle surface. An absorbent

~ *

('

material should be used with moderate wiping pressure. Sufficient measurements must be taken in the most appropriate locations to yield i

a representative assessment of the removable contamination levels.

5.3 Contamination Limits j i

NOTE: THE POLICY AT PBNP IS TO REDUCE REMOVABLE CONTAMINATION LEVELS TO

-- $MDA. THEREFORE, CONTAMINATION LEVELS GREATER THAN MDA REQUIRE THE APPROVAL OF A CHP SUPERVISOR PRIOR TO LOADING.

6.0 VEHICLE SURVEYS 6.1 Closed Tranraort, Exclusive Use Vehicle (49 CFR 173.441) 6.1.1 Vehicles designated as closed transport, exclusive use, must satisfy the following conditions.

a. Each package must be secured such that its position remains fixed within the vehicle during transportation.
b. There will be no loading or unloading operations between the beginning and end of the transportation.
c. The driver has been given ,pecific written instructions on how to maintain the shipment under the exclusive use designation. The instructions must be included with the shipping paper information.

6.1.2 After the transport vehicle is loaded, the following surveys

, aie required to check for removable contamination.

a. Complete a smear survey to check for the presence of removable alpha and beta-gamma contamination in those areas where contamination is most likely to occur, including cargo access doors and suspect areas as identified by visual inspections. As a minimum, take two smears on each interior side of the vehicle, two on

! the exterior surface of the trailer doors, and two on the off-loading area at the back of the vehicle. .

t i b. Move the transport vehicle to the controlled zone i barrier (if inside the controlled zone) and take a removable contamination (smear) survey of all vehicle l

tires. If the vehicle did not enter the controlled zone, tire smears are unnecessary.

Contamination limits are listed in Section 5.0 above.

j; b. The number of packages loaded on the vehicle must be j

' limited so that the sum of the transport index numbers of the packages does not exceed 50. (49 CFR 177.842)

! Example: Suppose three packages, each with a transport index of nine were to be shipped. The sum of the transport index numbers is_9 + 9 + 9 = 27.

This is an acceptable load. .

i f

RDW 5.7 Page 8 The vehicle driver is responsible for assuring that the addition of radioactive material packages to his load

.. will not result in a total transport index sum greater than 50. This is noted on form CHP-138, Carrier / Driver I

Instructions. (49 CFR 177.800)

! c. Radioactive material must not be shipped via commercial passenger carrying vehicles, such as a bus or taxi.

6.3.2 Perform a smear survey as follows:

f

c. If the vehicle has entered the controlled zone, move it i to the boundary, and complete a smear survey of all l vehicle tires as well as a smear survey of the vehicle 4

as described in Section 6.1.2 above.

d.

Contamination levels must not exceed the limits specified 4

in Section 5.0 above.

I:

6.3.3 Perform a radiation survey of each package to ensure that 1
