0023-HA-2015-001-Rev7 1 Objective and Scope The following instruction regulates the handling of the DN30-X package and is intended for the operator. This instruction can further be used to train operators on using the DN30-X package. In this instruction, handling situations are described, and instructions are given to comply with the certificate of approval. For the sake of a correct and safe use of the DN30-X package, this instruction has to be completely read and understood by the operator prior to handling the DN30-X package.
2 Further Applicable Documents The following documents are also valid:
Test instruction 0045-PA-2021-001 Periodic inspections of the 30B-X cylinder Contamination and dose rate measurements at the Test instruction 0045-PA-2021-002 DN30-X package Inspection criteria for regular and periodical inspections Test instruction 0023-PA-2015-016 of the DN30 package Geistiges Eigentum der DAHER-NUCLEAR TECHNOLOGIES GmbH Test instruction 0023-PA-2015-015 Periodical inspections of the DN30 PSP 3 Description of the DN30 PSP The DN30 Protective Structural Packaging (PSP) is shown in Figure 1 to Figure 6. It consists of a Property of DAHER-NUCLEAR TECHNOLOGIES GmbH bottom and a top half.
Lifting lugs at the feet as well as forklift pockets permit the safe handling of the DN30 package. The tie-down interfaces allow for safe stowing of the DN30 package and are compatible with existing PSP designs. The bottom half includes a valve protecting device with a separate housing, a plug protecting device, two rotation preventing devices, the bottom half of the seal holder as well as the bottom half of the closure system (composed of six closure devices).
The top half with integrated handling attachment points suitable for lifting the top half only includes the top half of the seal holder and the top half of the closure system. The information that the lifting lugs at the top half are allowed to be used only for handling of the top half is printed on both front faces of the DN30 PSP as is shown in Figure 5. Additionally, the lifting lugs at the top half have to be rendered inoperable during transport to avoid incorrect use.
The bodies of the bottom and top half are made of an inner and outer shell of stainless steel, both in the form of a tub, which are connected by a flange, respectively. The cavity between the inner and outer shells and flanges is filled with foam of different densities as well as a thermal insulation layer between the inner shells and the foam. In the flange of the top half, there is an elastomeric gasket to prevent inleakage of water during routine conditions of transport. To prevent dangerous pressure build-up, nine thermal plugs (or eight thermal plugs and one thermal valve) are embedded into the outer shell of the bottom and top half, respectively.
All surfaces of the inner shells of the bottom and top half are covered with a layer of intumescent material. In the bottom half, two silicon pads are located on top of the layer of intumescent material to reduce wearing.

0023-HA-2015-001-Rev7 The identification number of each DN30 PSP is engraved on the top and bottom part of two closure devices. That way the top half of each DN30 PSP is uniquely associated to its corresponding bottom half. Additionally, the identification number is printed onto both front faces of the bottom and top half of the DN30 PSP as well as on the nameplate.
The identification number is indicated on the separate housing of the valve protecting device as well, ensuring the housing is uniquely associated to a DN30 PSP. A highly visible label with red background color is glued onto the valve protecting device that reminds the user to not close the DN30 PSP before the housing has been put back into the valve protecting device (this is shown in Figure 6). This label is no longer visible when the DN30 PSP has been correctly prepared to be closed.
It is not possible to close the DN30 PSP without turning the handle of both rotation preventing devices into their closed position. Labels with red background indicating either the CLOSED or OPEN position are glued next to devices.
Note: The nameplates are always affixed to the front face on the plug side of a DN30 PSP.
This way, the valve and plug side of a DN30 PSP can be identified without opening a DN30 PSP.
