INTRODUCTION Modifications to current RCC containers have been undertaken with the aim of obtaining a new approval agreement regarding the transportation of UO2 assemblies The latest solution differs from the current design in terms of the following points:
The fitting of double-walled doors, filled with a neutron-absorbing resin, the full height of the assembly.
Attachments of these doors to the lateral cross members of the frame.
Reinforcement of the lower part of the frame and filling with neutron-absorbing resin.
Axial shock absorbers.
In order to prepare for the regulatory drop tests, a first series of evaluation tests was carried out in February 98 [1] on a specimen identified as PROTO 1. These tests, allowed us to make improvements to the design, increasing the containers' resistance to the regulatory tests. They also allowed us to assess the destructive potential of the drops in the most penalising conditions.
This document contains the specifications for tests to be carried out on a prototype, representing the new package model, produced with the aim of requesting an approval agreement. This prototype is described in a set of drawings [2].
- 2.
TEST OBJECTIVES The necessity of carrying out the tests described in this document comes as a result of the regulatory requirements for the application of the 1996 edition of IAEA Instructions, with the final aim of requesting an approval agreement for a new package model.
The tests described are those considered necessary in document [3]. There are 3 mechanical tests, listed in chronological order:
N° 1:
1 x Drop onto a Bar - Height 1 m - Angle lo N° 2:
1 x Drop onto a Bar - Height 1 m - Angle 0
N° 3:
1 x 9 m drop-flat
- 3.
CHOICE OF TEST CONFIGURATIONS Document [3] analyses the most penalising conditions in terms of package content and accident hypotheses for which resistance must be determined.
The configurations selected for the specimen, as well as the test type and parameters given later, have been determined by the analyses set forth in this document.

TEST SPECIMEN The specimen subjected to the tests was a 14 ft container capable of transporting 2 fuel assemblies. It was loaded with:
1 depleted uranium dummy assembly - type XL 17x17 lattice, containing -
depleted uranium rods in guide thimbles.
1 mock-up representing the equivalent mass and mass distribution of the aforementioned assembly Masses involved:
Empty container Dummy assembly + 25 rods Mock-up Total mass kg kg kg kg The specimen was identified as PROTO 2. Labelling is as defined in the diagram in Appendix 1.
- 5.
TEST STATION The tests were carried out on the CESTA target range in the Bordeaux region.
Characteristics of the drop facility The CESTA Outside Testing Ground (O.T.G.) is located in the town of LUGOS 33830 - BELIN-BELIET
- Route de la Gare du LUGOS - on the D110 (Regional Road).
A 30 Tonne, uni-directional gantry crane was positioned directly above a 2m x 1 m, 200mm thick, E36-2 steel central target, which, in turn, was placed alongside other steel plates of 100 mm thickness - forming a target of approximately 100 m2. This rigid slab was fixed to a 600 tonne concrete base foundation.
The target used for the regulatory test involving a 1 m drop onto a bar was a 150 mm diameter, low carbon steel bar. This bar was welded vertically onto a horizontal steel plate, which, in turn, was attached to the target defined above. The slenderness (height-to-length ratio) of the bar was 1.2 m:
this slenderness proved capable of penetrating the package without deflection (Tests: Proto. 1 ).
The drop was carried out using a explosive shackle so that the position of the specimen (set in place and checked before to the test) did not change prior to impact.
Optical observations of the impacts were made using 500 ips high-speed cinematography.
- 6.
INSTRUMENTATION Accelerometer probes were fitted the internal structure as shown in the diagram in Appendix 2. The frame-mounted probes were identified by the rib number supporting them (Rib 1 is the first intermediate rib starting from the foot of the assembly). For probes 5 and 6, their identification was completed by their angle of inclination.
For the drops onto a bar, only probes in positions 5 and 6 were used. These probes were screwed onto machined blocks, thus aligning them with the defined drop angles (
0 and 0
). These blocks were welded in the workshop onto the frame close to the ribs.

N° TFX DC 2108 EO FRAMATOME ANP REV. B PAGE 6/8 For the 9 m flat drop, only those probes positioned on ribs 1 9 and 10 were used. These probes were screwed onto mounting blocks, welded in the workshop close to the ribs.
For the 9 m flat drop, 2 accelerometer probes were also positioned on the fuel assembly. They were identified by the number of the assembly, i.e. F9A and F9A'. They were screwed directly onto the threading on the upper nozzle in the workshop. They were aligned along the O - 180° azimuth angle of the container, corresponding to the predetermined drop angle for the 9 m flat drop.
The accelerometers used were of the O - 20,000 G range with a minimum frequency of acquisition of at least 1111 KHz.
The accelerometer instrumentation channels were qualified and calibrated to within a known uncertainty.
- 7.
PROCEDURE The test sequence as defined in Para. 2 must be observed.
The container was neither opened between the drops nor upon completion of the drops. The expert appraisal was carried out at a later date in a different place. The only comments recorded on-site were those relating to any visual observations made during the procedure.
A photographic report, showing the external condition of the sample and the visible effects of the tests, was created, together with a video recording of the impact phases for each drop.
Following each drop, uranium contamination checks were carried out using test station equipment.
- 8.
TESTS In chronological order, 2 drops onto a bar and a 9 m drop were carried out on the targets described in paragraph 5.
8.1 Drop onto Bar N°1: Diagram Appendix 3 The specimen was placed above the bar with a longitudinal angle of incidence of 0°. The mating surface of the shells formed an angle of 0 with the vertical. These angles were determined with an accuracy of +/- 1 ° using the mating surface of the shells as a reference. The transverse position is such that the impact of the bar would be at the corner of the door to the cavity gap containing the assembly. The longitudinal positioning is such that the drop axis coincided with the cross-ways axis of the centre of gravity.
When in the factory, a visual identification mark was applied to the outside of the container, showing the point of impact on the shell.
The initial height between the bar and its point of impact with the shell was 1 m.

The mating surface of the shells formed an angle of 0 with the vertical. These angles were determined with an accuracy of +/- 1 ° using the mating surface of the shells as a reference.
The dummy assembly was located in the cavity gap exposed to the bar.
The longitudinal and transverse position is such that the door-bar contact took place on the upper surface of the door and the vertical line at the point of impact passed through the centre of gravity of the inner structure.
The initial height between the bar and its point of impact on the shell was 1 m.
When in the factory, a visual identification mark was applied to the outside of the container, showing the point of impact on the shell.
8.3 9m drop: Diagram Appendix 5 The specimen was placed at the centre of the target with a longitudinal angle of incidence with the frame of 1111 °, lower point bottom side, and an azimuth angle of incidence of 0°. The lowest point of the container was situated 9.14 m above the target (this additional height is due to the American scales used in the original IAEA instructions - 30 feet).
These angles were defined for the inner structure with an accuracy of +/- 0.1 ° longitudinally and +/- 1 ° transversally.
