N1-NHP-8 VAN SHIPMENT PREPARATION 1.0 PURPOSE AND SCOPE The purpose of this procedure is to identify the steps required to prepare a loaded radwaste van for offsite shipment.
Prepara-tion for shipment includes items such as surveying, closure and sealing, labeling and placarding, and documentation. Adherence to this procedure will ensure that shipments of radioactive waste are in compliance with applicable regulations of the NRC, DOT and Agreement States.
2.0 TECHNICAL SPECIFICATION REQUIREMENTS None 3.0 REGULATORY REQUIREMENTS 3.1 Refer to 10CFR71 for NRC requirements.
3.2 Refer to the following sections of 49CFR for DOT requirements:
40CFR 172, 173, 177, 178.
O 3.3 Refer to appropriate Burial Site Requirements for Disposal Criteria.
4.0 DEFINITIONS 4.1 Radioactive Material, 173.389*
Radioactive material is any material, or combination of materials, which spontaneously emits ionizing radiation. Materials in which the estimated specific activity is not greater than 0.002 micro-curies per gram of material, and in which the radioactivity is essentially uniformly distributed are not considered to be radioactive materials.
Special form radioactive materials are those which, if relecsed from a package, might present some direct radiation hasard but would present little hazard due to radiotoxicity and little possibility of contamination. This may be the result of inherent properties of the material (such as metals or alloys) or acquired characteristics, as through encapsulation. The criteria for determing whether a material meets the definition of special form are prescribed in paragraph 173.398(a).
- Refers to applicable sections of 49CFR (DOT).
N1-WHP-8
-1 March 1981
4.2 Type A and B Quantitles. 173.389(1)
^
Type A and Type B are defined as aggregate quantities of radioactivity which do not exceed the following f or Normal Form materials:
l Transport Group Type A Curies Type B Curies I
0.001 20 II 0.05 20 III 3
200 IV 20 200
.V 20 5000 VI, VII 1000 50000 l
For Special Form Materials 20 5000 4.3 Large Quantity Radioactive Materials. 173.389(b)
Large quantity radioactive material is a ' quantity of I
the aggregate radioactivity of which exceeds that specified as follows:
O h
Groups I or II radionuclides.............
20 curies Groups III or IV radionuclides...........
200 curies Group V radionuclid es....................
5000 curies Groups VI or VII radionuclides...........
50000 curies S pec ial Fo rm Ma terials...................
5000 curies l
Note that Large Quantities are those that exceed Type B quantities.
f 4.4 Fissile Radioactive Material, 173.389(a), 173.396 Fissile radioactive material is any material that contains i
certain quantities of plutonium-238, plutonium-239, uranium-233, or uranium-235, as specified in 173.396.
Packages of fissile material are classified cccording to the controls needed to provide nuclear criticality i
safety during transportation as follows:
1.
Fissile Class I This classification is assigned to packages which may be transported in unlimited numbers and in any arrangement, and which require no nuclear criticality safety
[
controls during transportation.
For purposes of nuclear criticality safety control, a transport
()
index is not assigned to ' Fissile Class I packages.
7 However, the external radiation levels may require a transportation index number.
j N1-NHP-8
-2 March 1981 l
l
~ 2.
Fissile Class II -- This classification is assigned to packages which may be transported llg together in any arrangement but in numbers which do not exceed an aggregate transport index of 50.
For purposes of nuclear criticality safety control, individual packages may have a transport index of not less than 0.1 and not more than 10.
However, the external radiation levels may require a highter transport index number but not to exceed 10.
Such shipments require no nuclear criticality safety control by the shipper during transportation.
3.
Fissile Class III This applies to packages which do not meet the requirements of Fissile Class I or II and which are controlled to provide nuclear criticality safety in transpor-tation by special arrangements between the shipper and the carrier.
4.5 Transport Group, 173.389(h), 173.390 Normal form radionuclides are classified according to their relative radiotoxicity and their relative potential transportation hazard into seven transport grcups (173.389 (h)- ).
The transport groups for most common g
radionuclides are listed in Table A herein (173.390).
W 4.6 Low Specific Activity Materials, 173.389(c)
Low Specific Activity radioactive materials are defined by any of the following:
1.
Uranium or thorium ores and concentrates.
2.
Unirradiated natural or depleted uranium or unirradiated natural thorium.
3.
Tritium oxide in water provided the concen-tration does not exceed SmCi/ml.
4.
Material in which activity is uniformly distributed and average concentration does not exceed the following:
Group I 0.0001 mci /gm Group II 0.005 mci /gm Group III, IV 0.3-mci /gm 5.
Nonradioactive objects externally contaminated with radioactive material, provided the con-tamination is not greater than the following:
Group I nuclides:
0.0001 mC1/cm2 ggg All other nuclides:
0.001 mci /cm-N1-MIP-8
-3 March 1981
f 4.7 Limited Ouantitv, 173.391(a)
Limited quantities are chose quantities that do not
~
exceed the following:
Group I 0.01 mci Group II 0.1 mci Group III, IV, V, VI 1.0 mC1 Group VII 25.
mci Special Form 1.0 mci Tritium Oxide in water 0.5 mci /ml (total not to exceed 3 curies)
U-235 15.
grams 4.8 Transport Index, 173.389(i)
The transport index is placed on a package to designate the degree of control to be exercised by the carrier during transportation.
The transport index to be assigned to a package of radioactive materials shall be determined by either subparagraph (1) or (2) below, whichever results in a larger value.
1.
The highest radiation dose rate, in millirem per O'
hour at three feet from any accessible external surface of the package; or 2.
For Fissile Class II packages only, the transport
(
index number calculated by dividing the number "50" by the number of similar packages which may be transported together as determined by the procedures prescribed in the regulations of the U.S. Nuclear Regulatory Commission. Title 10, CFR, Part 71.
4.9 Exclusive Use (or " Sole Use" or " Full Load"), 173.389(o) l I
" Exclusive Use" means any shipment from a single shipper having the exclusive use of the transport vehicle.
All initial, intermediate and final loading or unloading must be carried out by, or under the direction of, the shipper, the receiver, or the shipper's designated agent.
4.10 Closed Transport vehicle, 173.389(q) l i
" Closed Transport Vehicle" means a vehicle equipped with a securely attached exterior enclosure which restricts the access of unauthorized persons to the space con-taining the radioactive materials during normal transport.
The enclosure must limit access from top, sides and ends.
