- 1. Purpose
The purpose of this Chapter is to describe the re quirements applicable to the use of FCC3 packages.
- 2. Requirements applicable before first use
The checks to be carried out before the packaging is put into service are defined in § 8 of Chapter 1.4 of this Report.
- 3. Requirements applicable before each shipment
The list of checks to be carried out to prior to each shipment is given below. The sequence of this list may be adapted to suit operational requirements.
3.1. Content inspection
Compliance of shipped products:
Compatibility between the packaging and the content to be transported.
3.2. Packaging inspection
Check packaging validity date with respect to th e periodic inspections referred to in § 2.2 of Chapter 1.8 of this Report.
Check allowable deformation of the shock absor bers (defined in Chapter 1.4 of this Report).
Check allowable indentation of the container en closure (defined in Chapter 1.4 of this Report).
Check allowable deformation of reinforcements and gripping zones (defined in Chapter 1.4 of this Report).
Check for the absence of water or unauthorised foreign objects in the base of the bottom shell.
Check for the absence of flaking paintwork on the uninterrupted sections of the packaging.
Check gasket condition between the half-shells : replace it if needed.
3.3. Checks during loading
During and after loading of the assemblies or rod channels:
Check placement and locking of all ball-lock pins.
Check wedging of fuel rods in the channel.
Check maximum number of fuel rods loaded into the channels.
Check wedging of fuel assemblies and/or rod channels.
Check for internal contamination which must not exceed the following limits:
4 Bq/cm2 for beta and gamma radiation emitters and low-toxicity alpha emitters; and
0.4 Bq/cm2 for all other alpha emitters.
These limits are average limits applicable over any area of 300 cm² of any part of the surface.

On the closed package:
Check correct placement of the lid and check all bolts during torquing to ensure that the torque is N.m +/- %. The torquing recommendations are given in §5.4.
Check the regulatory compliance of labels and markings on the packagings.
Check on the respect of regulatory criteria of dose rates and of external surface contamination (packaging and means of transport).
Measure of the dose rate at 1 m fo r determination of the transport index.
Loading of packages:
Wedging and tie-down of the packages, strap attachment points on the packaging body must satisfy the following criteria:
The positioning of straps on the lifting boxes can be carried out over the full length of the box.
A tie-down arrangement with 2 straps on the lifting boxes and 2 straps in proximity to the 2 central reinforcing hoops of the container is also acceptable.
A tie-down arrangement with 2 straps placed on the upper half-shell reinforcement, in proximity to the "inner" reinforcing angle ba r of the lifting box is also acceptable.
Any strapping position less than 100 mm from the reinforcement is considered to be in proximity to the reinforcing hoop.
The placement of straps between 2 rein forcing hoops is expressly prohibited.
The safe working load of the straps is 5 tonnes maximum.
Check that the mode of transport is compatible with the transport index, the criticality safety index and the activity of the contents (e.g.: 100 A2 for river transport).
- 4. Empty packaging
The empty packaging is transported as an "excepted package" subject to the following requirements:
The packaging is closed and supported in accordance with the requirements in Chapter 1.8 of this Report.
The internal and external contamination levels meet the following criteria:
4 Bq/cm2 for beta and gamma radiation emitters and low-toxicity alpha emitters; and
0.4 Bq/cm2 for all other alpha emitters.
These limits are average limits applicable over any area of 300 cm² of any part of the surface.
The labelling is no longer visible.
The markings are compliant with regulatory requirements.

5.2. Loading of fuel assemblies
Transfer the fuel assembly using the bridge crane.
Place the assembly in the right-hand or left-hand cavity.
Press the assembly against the bottom plate.
Close the door and lock to the frame by means of the ball-lock pins.
5.2.1. Fuel assemblies without rod control clusters
Bring the pads into contact with the fuel assembly end grids and tighten with a torque wrench.

Secure the internal equipment handling lug to the bridge crane.
Unlock the support leg locking mechanism.
Slowly lower the internal equipment to t he horizontal position using the bridge crane.
Pin the top plates to the doors and the frame.

5.2.2. Fuel assemblies with rod control clusters
Actuate the fuel assembly axial restrain t system via the bottom nozzle (rotation and pulling).
Bring the pads into contact with the fuel assembly end grids and tighten with a torque wrench.
Repeat the above operations for the second assembly or the dummy.
Secure the internal equipment handling lug to the bridge crane.
Unlock the support leg locking mechanism.

Clamp all the spacer grid pads to ensure radial restraint.
Tighten the control rod cluster axially against the assembly with the top plate clamping system.
5.3. Loading of non-assembled rods
Non-assembled rods are placed in specially adapted channels positioned in the container instead of fuel assemblies.
The rods loading into the channels can be perform:
- Outside the container ;
- Or into the channel which was placed beforehand into the container.
The absence of loose parts or foreign materials is checked visually before the rods loading into the channels
In the case where the rods are the same length as the box:
Position the rod end support plate on the bottom of the box,
Place the rods in the channel in successive rows without exceeding the maximum number per row and per channel as indica ted in Chapter 1.3 Table 1.3-3,
If necessary, complete any rows using iner t rods (stainless steel rods or empty cladding tubes); the total number of rods (fuel and inert) must conform to the content listed in the applicable approval certificate,
Adjust the length by means of the nut/locknut on the end support plate.
In the case where the rods are shorter than the box:
Fit the axial spacers adapted to the rod configuration,
Place the rod end support plates on the bottom of the box,
Place the rods in the channel in successive rows without exceeding the maximum number per row and per channel as indica ted in Chapter 1.3 Table 1.3-3,

- 6. Quality assurance provisions
The provisions common to all activities and applicable to packaging operation and manufacturing activities are described in Chapter 1.9 of this Report.
6.1. Requirements specific to the manufacturing activity
For activities starting before 30 th September 2013, the rules and classification defined in section 7 of the Safety Analysis Report TFX DC 2159 Revision G are applied.
6.1.1. Conformity of the production documentation
The conformity between all equipment manufac turing documentation (including working drawings and acceptance test programme) and the definition of the package model as given in the Safety Analysis Report must be verified.
The party responsible for operations (manufacture r) is responsible for the conformity of the documentation produced (procedures, etc.) with reference to the safety analysis report requirements provided either directly or through documents written by a third party.
This third party must then guarantee the conformity of their documents to the Safety Analysis Report.
At the issue of each new approval certificat e (renewal or extension), the compliance of all documents must be certified once any changes have been taken into account.
6.1.2. Validation of manufacturing
Manufacturing quality surveillance must be fo rmally defined. A report must be produced for every inspection made. This repo rt must be identified and classified.
When the supplier has completed its services, the acceptance shall apply to the services and the associated documentation. The conformity of the results of the acceptance tests with the requirements specified in the safe ty analysis report must be checked by the manufacturer using the production spec ifications provided by the designer.
Inspections must be carried out by q ualified personnel for this activity.
6.2. Arrangements specific to operational activities
Conformity between all packaging operation documents (documents produced by the designer and/or the users) and the instructions for use of the package model given in the safety analysis report must be verified.
When using the package, the party responsible for the operations (plant operator, carrier, etc.)
is required to ensure the conformity of the documentation issued (operating procedures, etc.)
with the requirements of the safety analysis report received either directly or through documents written by a third party. This third par ty must then guarantee the conformity of their documents to the Safety Analysis Report.
