Transportation Certification Branch Approval Record Docket No. 71-9207 1
By application dated November 4,1985 EXXON Nuclear Company, Inc.
requested a one-time exemption for eight shipments of hoods, eauipment pieces, and miscellaneous solid wastes which are contaminated with plutonium and natural uranium compounds.
The waste forn reets the definition of low specific activity material (LSA).
The material is contained within M0 Equipment Burial casks. The casks 4
are constructed of 6-inch thick, concrete-steel reinforced rectangular bo3es. Thebgxesare.openatthetop.
The cask volumes range from 460 ft to 733 ft.
The hoods and other solids are loaded into the concrete boxes and all void spaces filled with concrete. At least 6-inch thick concrete covers the top of each box (package).
The weight of each loaded box varies from 32 tons to 51 tons.
The shipments will be made on approximately 17 miles of public road, avoiding heavy traffic hours.
The shipments will be escorted and will include a qualified health physics technician with appropriate survey instrumentation and barricading equipment. The escort team will be provided with written procedures for energency situations and will be trained in these procedures.
The route and schedule will be notified to the State Health Official, local fire departments, and the Department of Energy.
The State of Washington has no objections.
The burial casks have not been 'shown to meet the recuirments of Subpart E of 10 CFR Part 71.
However, containment is provided by encasing the LSA material in concrete. The heat load and the shielding requirements are of little significance for the material being shipped. The approval is not based on the structural analysis.
It was noted that:
1.
The analysis was based on the ultimate strength design method but
.no load factor was applied to the design load for flexure.
2.
The analysis was not based on the largest dimensions of the various containers.
3.
The analysis was based on a flat plate while the container wall would be subject to both tensile in-plane force and flexure. The effects of in-plane force and flexure should be conbined together.
l
-2 4.
The container wall horizontal rebar does not appear properly anchored into the supporting walls (see page 5, Attachment 1 of the application).
The ability of the horizontal rebar to develop moment resjstance near the support (at the junction of walls) is doubtful.
5.
The ~ botton plate analysis did not consider flexure.
The roller supports should be discussed in more detail.
6.
There are no shear reinforcement provided at the junction of walls or the junction of walls and the botton slab.
The licensee has been exempted from the package approval standards of Subpart E of 10 CFR Part 71. The exemption is based on the type and fom of the materials and the controls to be exercised for the limited shipments which will not endanger life or property.
