VERCORS Benchmark III
EDF Lab Paris/Saclay, 7 boulevard Gaspard Monge
Paris    France
Sponsor(s): EDF

Description:
EDF operates a large fleet of nuclear reactors and is responsible for demonstrating the safety of its installations, particularly the Concrete Containment Buildings (CCB). In France, the leak-tightness of a CCB is achieved with 2 technologies the first one with a metallic liner like in most CCB in the world and the second one with a double-wall containment without a metallic liner. The leak-tightness of the second type is linked to a series of complex and various parameters such as, the degree of cracking in the concrete and the opening of those cracks, the remaining pre-stress force, the delayed strains of concrete, the water saturation degree. To face this great challenge, EDF decided in 2014 to build a mock-up of a reactor containment building at 1/3 scale on EDF lab site. EDF thinks the best way to treat this challenge was to perform a series of benchmarks where each participant had the same data and the same given objectives to answer. There have been already 2 benchmarks organized, the first one in 2015 (early-age behavior and leak-tightness), the second one in 2018 (Creep modeling - Micromechanics and/or Multiphysics approaches; Mechanical behavior of the containment during pressurization test; Air leakage).
