1. Purpose

The purpose of this Chapter is to describe the re quirements applicable to the use of FCC4 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 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 the periodic inspections referred to in § 2.2 and 2.3 of Chapter 1.8 of this Report.

Check allowable faults of the shock absorber s (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 in the uninterrupted sections of the packaging.

Check gasket condition between the half-shells : replace it if needed.

For loads beyond the 5-year period after the last maintenance programme, the following additional checks must be completed:

Visual inspection of the visible surfaces of the shock absorbers, and:

Verification for absence of cracks.

In the event that traces of impacts are noted, a more in-depth analysis must be carried out on the absorber in order to chec k for the absence of cracks by a surface test (type - dye penetrant).

A verification of the general condition of the bolted connections fastening the shock absorbers to the upper shell and the fitting pads (no missing or corroded fastenings, verification of torque without disassembly) and the general condition of the bolts closing the two half-shells (no corrosion, functional condition free of seizure, no bearing stress of hexagon drives and good visual appearance). If t hese criteria are not respected, the bolts must be changed.

3.3. Checks during loading

During and after the loading of the assemblies or rod channels:

Check placement and locking of all ball-lock pins.

Check wedging of rods in the channel.

Check maximum number of rod rows loaded into the channels.

Check wedging of fuel assemblies and/or rod channels.

Check for internal contamination, whic h 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 applicable when averaged 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, tie-down strap attachment areas 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.

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).
