Application phase - This contract is intended to carry out simulation studies of normal operating situations on the one hand and accidental on the other hand, of MAVL and HA storage packages. Among the normal operating conditions of these packages are handling or gripping storage containers (body and lid, separately or not) and storage packages, and stacking storage packages. Among the accident conditions, exposure to an internal or external fire, the rise in internal pressure until explosion, the fall of the disposal packages are concerned.

The numerical simulations will have to make it possible to demonstrate the good dimensioning of the objects with regard to the performances which they are asked for.

The services will be performed at the premises of the holder, except for the meetings and progress points that will take place on one of the ANDRA sites.

PLACE reference number: CGRPFADAC190024.

Over the period 2020-2024, ANDRA wishes to achieve:

- numerical simulations with a mechanical focus (48-month firm phase). This lot includes the following services: modelizations of storage packages MAVL and / or HA in an estimated quantity of 21,

- drop simulations of MAVL and / or HA storage packages and analysis of mechanical consequences in quantities estimated at 45,

- simulations of the stacking situation of multi-level MAVL disposal packages in an estimated quantity of 15,

- simulations of handling and handling of lid, body, storage container or storage packages MAVL and / or HA in an estimated quantity of 20,

Note: Package drop simulations require the use of LS DYNA software.

Over the 2020-2024 period, ANDRA wishes to carry out numerical simulations with thermal and thermodynamic dominance (48-month firm phase). This lot includes the following services:

- simulations of exposure to fire from LLAV and / or HA storage packages in quantities estimated at 54,

- Simulations of gradual or sudden increase in pressure in a MAVL and / or HA storage package in an estimated quantity of 18.
