Abstract
A hollow metallic ring structure is secured to the periphery of the diagrid support and located within an internal annular space formed between the lateral neutron shield of the reactor core and an inner tank placed within a primary vessel. The ring structure is smaller in width than the annular space, has a maximum height equal to that of the reactor core, and is provided with partition-walls and holes for producing pressure drops and reducing convection currents.
