1. PURPOSE The purpose of this appendix is to present the classification of the components used in the TN-MTR package (packaging and the various authorised baskets) to determine the type and scope of the tests carried out or to be carried out during the manufacturing of the various elements making up this package model.
2. PRINCIPLE The TN-MTR package is used for routine and Normal Conditions of Transport (NCT) including minor incidents; it must therefore respect certain criteria related to the functions described below.

It must also remain 'safe' under Accident Conditions of Transport (ACT); additional acceptance criteria must also be respected (adapted to the accidental nature of the situations).

Direct safety functions:

A: containment B: dose rate (external radiation levels)

C: thermal behaviour D: criticality Indirect safety functions:

E: protection against drops F: protection against fire Other functions:

G: Protection against contamination N.C. : not classified For each of the above-defined functions, the component parts used in manufacturing of the package are classified in categories based upon the effect of a failure of these parts:

DOS-18-011415-037-NPV Vers.

2.0 Page 4 of 24 NON PROPRIETARY VERSION Category Effect of failure 1

Failure to respect a criterion applicable to ACT (Accident Conditions of Transport) when the packaging is subject to NCT (Normal Conditions of Transport) 2 Failure to respect a criterion applicable to ACT when the packaging is subject to ACT 3

Failure to respect a criterion applicable to NCT when the packaging is subject to NCT, however the criterion applicable to ACT is respected 4

Change from NCT to ACT 5

No impact on safety "Failure" is defined as the total loss of the safety function(s) assured by this part under routine, Normal or Accident Conditions of Transport.

Component parts of the package are not all the same in terms of ease of testing, repair or replacement during periodic maintenance imposed in the Safety file, therefore there is an additional maintainability classification index:

Maintainability index Criterion 1

Part, component or sub-assembly that is very difficult or even impossible to test during maintenance and impossible to change or repair without fully reconstructing the packaging or the basket.

2 Part, component or sub-assembly that is difficult to test during maintenance, but that can be replaced or repaired 3

Part, component or sub-assembly that is easy to test during maintenance but impossible to change or repair without fully reconstructing the packaging or the basket.

4 Part, component or sub-assembly that can easily be tested during maintenance and that can be replaced or repaired during maintenance.

5 Part, component or sub assembly that is easy to test and that can be changed or repaired when the packaging is in use before shipment.

For each component in Chapters 0 and 0A, Tables 7A-1.1 to 7A-1.13 show applicable direct or indirect safety function(s), the category related to the effect of a failure of the part and the maintainability index, according to the above classification.

    • Not done Physical characteristics are verified based on a certificate of conformity.

(1) For the "criticality" function, the chemical analysis may be replaced by a neutronic test and for the "dose rate" function, by accurate weighing of basic components and performing additional tests to be defined (density, physical characteristics, etc.).

(2) Physical Characteristics: conductivity, melting temperature, coefficient of expansion, etc. The heat tests are only carried out on materials with special specifications (not covered by standards or standard specifications, for which a Certificate of Conformity will be sufficient).

(3) For specific cases, when the performance and interpretation of this test cause problems (neutron-absorbing resin, baskets, seals, etc.) a process qualification, supported by additional manufacturing tests (destructive testing) and statistical analysis or by operational testing may replace the volumetric inspection.

(4) In accordance with EN 10204, the independent organisation may be the authorised representative of the manufacturer that is hierarchically independent of the manufacturing services.

Acceptance criteria are defined in order to upper-bound the requirements laid out in this Safety file.
