- b. This certificate does not relieve the consignor from compliance with any requirement of the regulations of the U.S. Department of Transportation or other applicable regulatory agencies, including the government of any country through or into which the package will be transported.
- 3. THIS CERTIFICATE IS ISSUED ON THE BASIS OF A SAFETY ANALYSIS REPORT OF THE PACKAGE DESIGN OR APPLICATION
- a. ISSUED TO (Name and Address) b. TITLE AND IDENTIFICATION OF REPORT OR APPLICATION Orano NCS GmbH Safety Analysis Report for the DN30-X Package Margarete-von-Wrangell-Strae 7 0045-BSH-2020-001-Rev.3, dated November 2022, as D-63457 Hanau - GERMANY supplemented.
- 4. CONDITIONS This certificate is conditional upon fulfilling the requirements of 10 CFR Part 71, as applicable, and the conditions specified below.
5.
(a) Packaging (1) Model No.: DN30-X (2) Description The DN30-X packaging consists of the DN30 protective structural packaging (PSP) and the 30B-X uranium hexafluoride (UF6) cylinder.
The DN30 PSP is a right circular cylinder constructed of two austenitic stainless steel shells:
(i) the bottom half with integrated feet, a valve protecting device, a plug protecting device, two rotation preventing devices, lower part of the closure system (consisting of six devices),
and handling attachment points, and (ii) the top half with the upper part of the closure system and integrated handling attachment points for the top half.
For both the bottom and top halves of the PSP, the cavity between the inner and outer shells and the flange is filled with a polyisocyanurate rigid (PIR) foam with a layer of 10 mm thermal insulation between the inner shell and the foam. All the surfaces of the inner shell of both the top and bottom halves are covered with a layer of intumescent material.
The valve protecting device, enclosing the valve of the 30B-X cylinder, and connected to the bottom half of the DN30 PSP by two hinges, consists of a casing of stainless steel filled with PIR foam and a protective housing with its inner walls covered with an intumescent material.
NRC FORM 618 U.S. NUCLEAR REGULATORY COMMISSION (8-2000) 10 CFR 71 CERTIFICATE OF COMPLIANCE FOR RADIOACTIVE MATERIAL PACKAGES 1 a. CERTIFICATE NUMBER b. REVISION NUMBER c. DOCKET NUMBER d. PACKAGE IDENTIFICATION NUMBER PAGE PAGES 9388 0 71-9388 USA/9388/AF-96 2 OF 4 5.(a) Packaging (continued)
The two rotation protecting devices, welded at the sides of the inner flange of the bottom half of the PSP, are identical and consist of a pin, withdrawn into the flange during loading, and inserted, during transport, into the two holes in the skirt of the 30B-X cylinder.
The plug protecting device is welded to the inner shell of the bottom half of the PSP and allows the plug to move in the axial direction without making contact with any part of the PSP. An elastomeric gasket, installed in the flange of the top half, prevents water in leakage during normal conditions of transport.
The PSP has a nominal length of 2,437 mm, a nominal external diameter of 1,216 mm, and a nominal height of 1,329 mm. The nominal gross weight of the package is 4,012 kg.
The 30B-X Cylinder contains an interior criticality control system (CCS) that consists of criticality control rods (CCRs), filled with neutron poison material in the form of boron carbide (B4C), and lattice holders to keep each CCR in place. Longitudinal stiffeners between the lattice holders help to keep the lattice holders separated from each other. The length of the CCRs is fitted to the elliptical heads of the 30B-X cylinder. The two CCRs that end in front of the valve are shortened by 40 mm to facilitate filling and emptying of the cylinder.
The 30B-10 cylinder (with a maximum enrichment of 10 wt.% 235U) includes 33 CCRs while the 30B-20 cylinder (with a maximum enrichment of 20 wt.% 235U) includes 43 CCRs. Apart from the B4C filling, the CCS is made of carbon steel for low-temperature service, like the pressure envelope of the cylinder.
Both cylinders have a nominal length of 2,070 mm, a nominal diameter of 762 mm, a nominal wall thickness of 13 mm, and an identical nominal gross weight of 2,912 kg: the 30B-10 has a nominal tare weight of 1,452 kg and the 30B-20 has a nominal tare weight of 1,641 kg.
