A tungsten liner is also used in conjunction with insert 4081 to provide additional shielding. Dimensional checks shall be carried out on the inserts and tungsten liner in accordance with Section 8.1.1. This is considered an adequate shielding check due to the simple design of the inserts and the tungsten liner.
Safkeg-HS 3977A Docket No 71-9338.
CTR 2008/11, Rev 16 Page 8-5 CTR2008-11-R16-Sc8-v2.docx For the containment vessel either ultrasonic testing of the DU at the component stage or a gamma scan of the containment vessel shall be carried out.
The gamma scan shall be performed over the surface of the containment vessel lid and body on completion of manufacture. The measured dose rates are compared to the dose rates calculated for the surface of the containment vessel lid and body with the minimum dimensions and the minimum density of the DU and stainless steel, as well as the chemical composition, all as specified in the Certificate of Compliance drawings. The calculations and the measurements (the scan) shall use the same source, the same source quantity, and the same geometry and configuration (of the source, shielding and detector). The DU lid and body shielding are acceptable if the measured dose rates do not exceed the calculated dose rates.
8.1.7 Thermal Tests A prototype package has been fully tested as described in Section 2 and shown to perform satisfactorily under both Normal Conditions of Transport (NCT) and Hypothetical Accident Conditions (HAC).

This package has no special thermal features other than the cork insulation. With the low heat load and the design margins on allowable material temperature, the package requires no special thermal testing as part of the post-manufacture acceptance test.
8.1.8 Miscellaneous Tests Not applicable.

8.2.3.1 Stainless Steel Surfaces All of the stainless steel surfaces of the keg and containment vessels shall be visually inspected for corrosion. The presence of any surface corrosion on any component shall be cause for further inspection. If the corrosion can be easily wiped off, and no pitting is apparent beneath it, the component is acceptable. If the corrosion cannot be easily wiped off, or if scaling is present, or if pitting is observed, then the surface shall be reworked and the component must undergo a dimensional inspection and dye penetrant and/or radiographic testing to determine the extent of the damage.
In the case of the containment vessel, a hydrostatic test shall be performed. All acceptance criteria for a newly fabricated component (drawing 1C-5944 for a standard CV lid, drawing 1C-7504 for a split CV lid for insert 4081, and drawing 1C-7944 for the split CV lid for insert 4109) shall apply to the reworked component. If the corrosion has compromised the structural integrity of the component (e.g. the component no longer meets dimensional criteria for a new part as specified on drawing 1C-5944 for the standard CV lid, 1C-7504 for the split CV lid for insert 4081 and drawing 1C-7944 for the split CV lid for insert 4109), then the component shall be rejected. The inspection results and any necessary replacement or repairs, shall be recorded in the package maintenance records.
