Fissile Material-Shipments and Exemptions AGENCY: Nuclear Regulatory Conmission.

ACTION: Final rule.

SUMMARY

The Nuclear Regulatory Conmission (NRC) is amending its regulations regarding the shipment of exempt-quantities of fissile material and ae
shipment of fissile material under a general license. This emetgency final-rule t estricts the use of beryllium and other special moderating materials (i e.,- graphite and deuterita) in the shipment of fissile materials and

-consigns quantity. limits on fissile exempt shipments. These amendments are necessary to correct a recently discovered defect in the current regulations which could permit, in special circumstances, nuclear criticality to occur in shipments of fissile materials which are. permitted to take place without specific Commission appr. oval.

The regulatory defect is not indicative of unsafe fissile material shipments in the past, Rather, it was identified by Babcock & Wiicox (B&W) during preparation for shipment of an unprecedented type of fissile material-that could result in nuclear criticality under current requirements. This unique m uerial is produced as a waste product from processing of strategic material iesulting from operations to

Background

11,1996,=anNRCfuelcyclefacilitylicenseeb8aNock&

On September Wilcox,. Naval Nuclear fuel Division-(8&W), notified NRC by telephone that it had discovered that the NRC and U.S. Department of Transportation (DOT) regulations (10 CFR 71.53_ and 49 CFR 173.453, respectively) on fissile e m pt shipments do not provide adequate criticality safety for certain ship. Tents of a fissile material' (enriched uranium containing beryllium oxide.)

Specifically, B&W discovered through calculations, that a shipment,-intend to be shipped pursuant to S 71.53(d), containing large amounts of an exempt concentration of enriched uranium in the presence of beryllium, could result in a nuclear criticality'.

B&W indicated that a beryllium oxide enriched uranium mixture would be produced bs a waste product from its processing of strategic material resulting from ogrations to comercially downblend B&W promptly weapons-usable fissile material from the former Soviet Union.

notified the NRC of its concern, provided its calculations to the NRC, and

' Fissile material is defined in 10 CFR Part 71 and 49 CFR Part 173 plutonium-238, plutonium 239, plutonium-241, uranium-233, uranium-235, or any combination-of these radionuclides.

Packages used for shipment of materials

.containing these radionuclides must meet specific standards and operating '

limits designed to preclude nuclear criticality during transport, unless-excepted by specific regulations (e.g.,10 CFR 71.53 or 49 CFR 173.453).

'For transportation purposes, nuclear criticality means a condition in which an uncontrolled, self-sustaining and neutron-multiplying fission chain Nuclear criticality is-generally a concern when sufficient concentrations and masses of fissile material and neutron moderating m

. revisions to NRC regulations are needed to correct the deficiency because an inadvertent nuclear criticality'in the public drain could irelve fatalities <

health effects:from the resulting radiations and extensive clean-up costs.

The criticality safety problem brought to NRC's attention with respect to G 71.53 caused the NRC staff to review 10 CFR Part 71 to determine whether any other provisions of this_ Part might be similarly deficient.

The generi, l

licenses in 59 71.18 and 71.22 provide for criticality control by limiting the

- quantity of fissile material in a singla package (i.e., similar to the quantity-based fissile exemptions in 10 CFR 71.53).

Section 71.18 also

_ assigns a criticality transport index (pursuant to S 71.4) to each package.

These sections were found to have deficiencies comparable to those discovered in S 71.53 in that there are no restrictions placed on special moderating materials (i.e..- materials which would increase the number of neutrons available to cause fission as compared with ordinary water), and S 71.22 has the' additional deficiency of not limiting the total amount of fissile material During the NRC staff's review, sections S 71.20 and S 71.24 in a conveyance.

which also provide general _ licenses, were found to be adequate in that the moderators of concern were excluded.

Packages for shipments made in accordance with a fissile material exemption in S 71.53 or the general license in S 71.18 or S 71.22. are not required to be certified by NRC. The intent of SS 71.53, 71.13. and 71.22 is that any materials packaged and shipped in accordance with the limits in these-r

-4

h 4

isections;(and theiother-applicable sections of 10 CFR Part "I and 49 CFR-Part 173) are incapable of an inadvertent criticality.

The B&W analyses.

demonstrated that a deficiency exists in these requirements.

The NRC has already taken a number of actions to resolve the potential safety problem identified by S&W.

First, the NRC obtained a cortraitment from.

B&W not to ship Be U materials without orior NRC_ authorization and confirmed this commitment in a Confirmatory Action L.etter (CALL datea October 10.19f 5.

Subsequently, the CAL wcs superseded by an immediately effective Confirmatory Order Modifying License dated December 16, 1996, wilich imposed B&W's cormiitment as-a-legally binding license condition.

The NRC had no reason to doubt B&W's earlier voluntary commitment because B&W had demonstrated its concern for safety by bringing the problem in the first place to the NRC's attention.

However, the NRC staff also believed that, given the significance of this issue for public_ health and safety, the NRC needed to exercise its full authority to assure itself and the pu'blic that the one licensee known to be in a position to make potentially unsafe shipments was legally prevented from doing so'pending completion of this rulemaking.

On December 5, 1996. NRC also issued HRC Information Notice 96-63 to all NRC licensees authorized to possess special nuclear material.

The purpose of this information notice was to alert all such licensees to this problem so lthat any of them who might be in a position to make potentially unsafe shipments could take appropriate measures.

The NRC also brought this problem to the attention of the U S.

Department of Transportation (00T) and the U.S. Department-of Energy (DOE),

- many-shipments of fissile exempt material. each year.

Discussion The safety problem uncovered by the B'& W calculations, and. verified by the NRC, involves quantities, geometries, and concentrations of fissile materials and moderators which could result in criticality when shipped tri compliance with sections of the regulations for which criticality analyses are not required. The current regulations (fissile exemptions in S 71.53 and the

- general licenses in SS 71.18 and 71.22) are based on the assumption that water

- is the only moderator which might be present in fissile exempt shipments.

These rules are assumed to provide inherent criticality safety without a need

-for shippers to perform separate analyses. However, some moderators (herein referred to as special moderating materials) can increase the number of neutrons available to cause fission as compared to ordinary water and result

~

in the potential for criticality in shipments where these moderators are present, even though the shipments are in compliance with 10 CFR 71.53 and 49 CFR 173.453.

Untii recently, the presence of special moderating materials in significant quantities in NRC-regulatet shipments of fissile exempt materials was not anticipated. However, certain international initiatives, including efforts of reduction in stockpiles of strategic material by processing for commercial use, have resulted in the greater likelihet,d of inclusion of these materials in NRC regulated shipments The materials proposed to be shipped by 6-

E A recent

B&W, which prompted this fina! rule, resulted from such a source.

contract was awarded to B&W to-process weapons usable _ enriched uranium i

' materials from the_ Republic of Kazakstan.

The waste product of the o

processing. a uranium-beryllium filtercake, met-the fissile exemption provisions in 10 CFR 71.53(d) and 49'CFR 173.453(d).

However. B&W used a computer model of the enriched _ uranium beryllium oxide waste packages, to

~

demonstrate that if the packages were loaded for shipment into a sea-land container, and at the regulatory fissile exempt concentration limit, adequete confidence in nuclear criticality safety would not have been provided.

NRC has-verified through independent analyses that the concerns raised by the B b

~

analysis are valid and apply to other geometries and moderating characteristics as well. To guard against inadvertent criticality, this final rule restricts shipments of fissile material with three special moderating materials: beryllium, graphite, and deuterium.

However, limiting beryllium, graphite, and deuterium to trace quantities would not completely eliminate the possibility of criticality in fissile exempt or generally licensed shipments, There is also a need to limit the quantity of material in a single corsignment (the B&W criticality model calculations were performed using 200 cm high infinite slab configuration).

The problem of a lack of control on the total amount of fissile exempt material in an exempt shipment, was originally identified during the revision process for the 1996 Edition of the International Atomic Energy Agency's (IAEA's) " Regulations for the Safe Transport of Radioactive Material," Safety Series No. 6,-1996. The problem was addressed in Safety Series No. 6, 1996, by adopting a consignment limit on the amount of fissile exempt material that' a shipper could transport as a private carrier or deliver to a conmon carrier 7

forishipment.

The NRC cannot presently _ enforce a limit on the total quantity

- of-fissile material in a common carrier shipment because the regulations do not require a transport index for each package-or require shipment by_

exclusive use.

The lattr.(would restrict:the ability to use conmon carriers, wtiile requiring a trantport index would negate much of the advantage gained by the exemption.

Consigtment limits are enforceable and represent a practical operating limit that would prevent the potentially unsafe accumulation of fissile exempt materials during shipment.

I Therefore, this final rule restricts special moderating materials and includes consignment limits on shipments of fissile materials under the

- provisions of SS 71.22 and 71.53. This final rule also restricts special moderating materials under the provisions of S 71,18. Together these changes will eliminate the possibility of inadvertent criticality during shipments made in compliance with 10 CFR 71.13, 71.22. or 71.53. The NRC anticipates that DOT will issue parallel revisions to 49 CFR Part 173.

Accordingly. NRC and D0T are coordinating the necessary revisions to 10 CFR Part 71 and 49 CFR Part 173.

2 Compatibility with the IAEA Standards On September 9. 1996.' the Board of Governors of the IAEA approved the 1996 revisions to Safety Series No. 6.

Among the changes in these revised IAEA regulations are that consignment limits and limits on the types of moderators were placed on the f3sile exemptions:in paragraph 672 of Safety 15eries'No._6, 1996.

The changes to 10 CFR Part 71 made by this rulemaking are generallv compatible with the changes made to IAEA Safety Series No. 6, 1996.

Future revisions to.10 CFR Part 71 and 49 CFR;Part 173 are planned by NRC and 100T_. respectively, to bring them into general-accord with other sections of-1 IAEA SafetyJSeries No; 6;-1996c

000 area in which this final rule.for 10 CFR Part-71 is not ' compatible with I AEA Safety Series No. 6,1996,- paragraph;672 is that graphite was added

'as a special moderating material in the 1995 revisions to 10 CFR Part 71 (60-FR 50248), but does not appear in.IAEA Safety Series No. 6, 1996.

[ Graphite is limited by the current general licenses in 10 CFR 71.20 and 71.24.] The

~NRC believes that it is appropriate to continue to limit graphite fbeing a Lspecial moderating material) in domestic regulations for shipment of fissile material. Therefore, the revisions to the fissfle exemptions in 10 CFR 71.53 and the general licenses in 10 CFR 7hl8 and 71.20 provide-for exclusion of-other than. trace quantities tf graphite.

Alternatives Considered To determine the appropriate amendments to 10 CFR 71.18, 71.22. and 71.53, the NRC staff considered the-following three alternatives:

1. -The No Action Alternative.

This alternative is not acceptable to

_the NRC. Shipments 'of fissile material (Be U mixtures) meeting the fiss11e material exemption requirements could t:e made in a configuration that does not maintain criticality safety during transport. Therefore, this alternative was not pursued.

2.

Eliminate the fissile material exemotion. This alternative is not acceptable to the N9C.

Elimination of fissile material exemption, while 9

so_lving the criticality safety problem identified by-B&W, would create other Eproblems Many packages, such as those containing low-level radioactive waste materials (e.g.. ion-exchange resins), contain only trace concentrations of fissile nuclides which are incidental to the overall radioactivity-of the

- package contents, and criticality events are not credible-for shipments of these packages.

The S 71.53 fissile material exemptions are applied for these

~ shipments, and there is a continuing need to provide for this application; Elimination of S 71.53 would place an additional burden and cost on many Therefore.

.' shippers whose shipments posed no criticality safety concerns.

this alternative was not pursued.

3.

Revise the fissile material exemotions in S 71.53 and the ceneral licensees in SS 71.18 and 71.22 to exclude the cresence of soecial moderat.jflg materials such as beryllium; deuterium-and craohite in other than trace cuantities. and olace consianment limits on shioments.

Together these changes solve the criticality safety problem identified by B&W and tt'e re n ted problem of the potential accumulation of an unsafe quantity of fissile materials in a shipment, Given the limited number of affected shipments and the small number of licensees involved, some additional costs on shippers may be expected because they can no longer use the fissile material exemptions and general licenses for materials with beryllium, deuterium and graphite in other then trace quantities, and because some shipments may have to be divided to meet the consignment limits, it keeps the exemption and general license provisions available for other shippers. This alternative was chosen by the NRC staff, and is the basis-.for the following specific changes in SS 71.18, 71.22. and 71.53. -

Good Cause for immediate Adoption The Comnission is promulgating this emergency final rule because the problem of regulatory safety limits over quantities and concentrations of fissile material and moderators, which has been demonstrated to permit criticality in at least one proposed shipment, is an important safety issue meriting innediate corrective action. An accidental nuclear criticality in the public domain would very likely' involve _ fatalities, health effects from

~ the resulting radiations, and extensive clean-up costs.

Shipments of fissile exempt material are normally made without any associated crit 1cality Jnalysis because in the past it has been assumed that the regulations provide inherent criticality safety.

H wever, B&V s i

contemplated shipnent demonstrates that this assumption is not correct for all possible types of shipnents. While the Conniission expects that B&W's corrrnitment. as expressed in the NRC's Confirmatory Order, not to undertale snipments without the prior approval of the NRC, and the Information No; ce issued to all licensees authorized to possess special nuclear material, will prevent an unsafe shipnent from occurring pending revision of its rules, the Coninission does not track shipments by licensees made under the provisions of 10 CfR 71.18. 71.22, or 71.53.

Moreover, the nature of the materials being imported and shipped domestically has recently changed due to initiatives with the States of the former Soviet Union to reduce weapons usable material such as high enriched uranium.

The materials B&W had intended to ship were byproducts from processing this type of material.

Shipments made under 10 CFR 71.18, 71.22 or 71.53,1re made without specific NRC approval and the possibility exists that a licensee could unwittingly make an unsafe shipment in reliance upon the present rules.

Thus, the Conintss9n must amend its rules quickly to prevent unsafe shipments from occurring.

For the reasons stated above, the Conini sion finds good cause, pursuant to Section 553(b)(B) of the Administrative Procedure Act (APA) (5 U.S.C.

553(b)(B)).-to dispense with notice and prepromulgation public coninent as being impracticable and contrary to the public interest, further. the Coninission finds, pursuant to Section 5E3(d)(3) of the APA (5 U.S.C.

553(d)(3)), that good cause exists for neL!ng these amendments immediately,

effective because the need to have these regulations in place outwe:ghs the j

inconvenience, if any, to licensees who may need to alter shipping clans, Nevertheless, the Consnission is providing a 30 day post promulgation public cument period during which interested persons are invited to submit their coninents to the Conrnission. Within a reasonable time after the end of the coninent period, the Conin1ssion will publish a statement in the Federal Register containing an evaluation of the significant contrents received and any revisions of the rule to be made as a result of the conrients.

finding of No Sign 1ficant Environmental Impact: Availabihty The Cumiission has determined, under the National Environnental Policy Act of 1969, as amended, and the Camiission's regulations in Subpart A of 10 CfR Part 51 that this rule 1s not a major federal action significantly affecting the quality of the human environment, and therefore an environmental impact statawnt (EIS) is not required.

The Coninission's " final Environmental Statement on the Transportat. ion of Radioactive Material by Air and Other Modes." NUREG 0170, dated December 1977.

is NRC's generic ElS covering all types of radioact1ve material The total limited transportation by all modes (road, rail, air, and water).

quantity impacts were included in the overall transportation rist assessment in NUREG-0170 and found to be acceptable.

The radiological safety impact estimates in this EIS clearly bound the impacts for limited quantity shipments of fissile material containing special moderating materials.

This final rule affects only a small subset of the limited quantity shipnents, i.e., those that contain both fissile material and special moderating materials, NUREG 0170 does not specify the annual number of limited quantity, tissile material shipments containing special moderating m

materials. but does estimate that 50,000 NRC certified fissile material packages (used for larger quantities of. and/or more highly enriched, fissile materials) would be shipped in 1985. The ntaber of shipments affected by this i

final rule is a small fraction of the NRC certified fissile package shipments because fissile materials containing special moderating materials are less conmon than troderately enriched fissile materials.

The options available to licensees under this final rule include shipping the material using different administrative controls (i.e., shipping it as a fissile material and not using the quantity limited exemption / general license) or reducing the special moderating material concentration to specif kd limits. The NRC statf believes the first option may prove more economical because the increase in cost in making a' single shipment under fiss11e material controls is less than that involved in reducing or removing the special moderating material.

Under this option, the same number of l

shipments are made as before the rule change, but shipments of fissile f

materials containing special moderating material would be made in NRC certifie' packages. Under the latter option, the concentration of special moderating material might be reduced through additional processing, perhaps involving dilution or extraction. This option may involve additional transportation, either due to the increase in shipment volume due to dilution, or the transportation of extracted materials, Since the quantities of affected fissile materials are relatively small, staff believes the additionai transportation would also be small.

The two options provide the added nuclear criticality safety control the rule seeks, either through the use of NRC-certified packages, and the administrative controls associated with their use, or through the reduction of ;

, - + -,..

r the concentration of special moderating materials to an acceptably low level.

Thus, the ultimate environnental inpact of the rule is beneficial in that criticality safety is increased.

The Honorable Dan Schaefer, Chairman Subcommittee on Energy and Power Committee on Commerce United States House of Representatives Washington, DC 20515

Dear Hr. Chairman:

The NRC has sent to the Office of the federal Ryister for publication the enclosed final rule to amend 10 CFR Part 71 for fissile material shipments and exemptions.

on NRC fuel cycle facility licensee, Babcock & Wilcox (B&W), notified the NRC on September 11, 1996, that it had discovered a defect in the current NRC and Department of Transportation (DOT) regulations, in 10 CFR 71.53 and 49 CFR 173.453 respectively, which could cause nuclear criticality to occur in shipments of fissile material.

The regulatory defect is not indicative of unsafe fissile material shipments in the past.

Rather, it was identified by B&W during preparation for shipment of an unprecedented type of fissile material that could result in nuclear criticality under current requirements.

This unique material is produced as a waste product from processing of strategic material resulting from operations to commercially downblend The NRC weapons-usable fissile material from the former Soviet Union.

reviewed its regulations and determined that revisions to 10 CFR Part 71.53, were needed on an emergency basis because shipments under these 71.18, 71.22 three sections can be made without specific HRC approval, in aridition to this rulemaking, the NRC has taken other actions to protect public health and safety, including obtaining a commitment from B&W not to An make such shipments and confirming this with a legally binding order.

Information Notice was also issued to all special nuclear material licensees.

This rule will utilize'the " good cause" exception to the Administrative Procedure Act's (APA's) requirement for notice and comment (5 U.S.C. 553 (b)(B)), as permitted under 10 CFR 2.804(d)(2) of the Commission's t egulations, because providing public notice and comment is impractical and contrary to public interest in this case where an inadvertent eriticality in the public domain could involve f atalities, health effects from the resultant radiation, and extensive clean-up costs.

This rule will also utilize the

" good cause" exception to the APA requirement that a final rule must be

NUCLEAR RESULATORY COMMISSION C

The Honorable Newt Gingrich Speaker of the United States House of Representatives Washington, DC 20515

Dear Mr. Speaker:

Pursuant to Subtitle E of the Small Business R> 7ulatury Enforcement f airness Act of 1996, 5 U.S.C. 801, the Nuclear Regulatory Comitsion (NRC) is submitting a final rule amending its regulations in.0 CFR Part 71 for fissile An NRC fuel cycle facility licensee, material shipments and exemptions.

Babcock & Wilcox (B&W), notified the NRC on September 11, 1996, that it discovered a defect in the current regulations in the NRC 10 CFR 71.53 and the 00T 49 CFR 173.453, which could cause nuclear criticality to occur in shipments of fissile material.

The regulatory defect is not indicative of unsafe fissile material shipments in the past.

Rather, it was identified by B&W during preparation for shipment of an unprecedented type of fissile material that could result in nuclear criticality under current requirements.

This unique material is produced as a waste product from processing of strategic niaterial resulting from operations to commercially downblend The NAC weapons-usable fissile material from the fnrmer Soviet Union.

71.53, reviewed its regulations and determined that revisions to 10 CFR were needed on an emergency basis because shipments under these 71.18, 71.22 three sections can be made without specific NRC approval.

We have retermined that this rule is not a " major rule" as defined in 5 U.S.C.

We have confirmed this determination with the Office of Management 804(2).

and Budget.

Enclosed is a copy of the final rule, which is being transmitted to the of fice of the Federal Register for publication. Neither a Regulatory flexibility Certification nor a Regulatory Analysis has been prepared for this final rule which has insignificant economic impact on NRC special nuclear material licensees.

This rule will utilize the " good cause" oxception to the Administrative Procedure Act's (APA's) requirement for notice and comment (5 U.S.C. 553 (b)(B)), as permitted under 10 CFR 2.804(d)(2) of the Commission's rcgulations, because providing public notice and comment is impractical and contrary to public interest in this case where an inadvertent criticality in '

the public domain could involve fatalities, health effects from the resultant This rule will also ut111ze the radiation, and extensive clean-up costs.

" good cause" exception to the APA requirement that a final rule must be
