- This storage device intended to be housed in a cavity of a package, is designed so as to be able to simultaneously fulfill three essential functions, which will be briefly explained below.
- the second function concerns neutron absorption, and the concern to maintain the sub-criticality of the storage device when the latter is loaded with the fuel assemblies. This is achieved by using neutron absorber materials known as neutron absorbing materials, such as boron.
- the third essential function relates to the mechanical strength of the device. It is noted that the overall mechanical strength of the device must be compatible with the regulatory safety requirements for the transport / storage of nuclear materials, in particular with regard to the so-called “free fall” tests.
- transverse structures such as pancakes, spaced apart others by spacers
- longitudinally oriented liners pass through the transverse structures, and each form a housing for receiving a nuclear fuel assembly.
