  • Publication number: 20240302737
    Abstract: A method for sizing a greyscale lithography mask is disclosed. The mask includes first opaque zones, being opaque to light-exposing radiation, located in first pixels forming a first mask grating. A first target density of a first surface density of first opaque zones is first established. This first target density makes it possible to expose a resin to light over a first given target thickness when it is exposed to the radiation through the first grating. The dimensions of the first pixels and the dimensions of the first opaque zones are then established, such that the value of an error over the first target thickness is less than a first given threshold. The dimensions obtained for the sizing of the first mask grating are used.

  • Publication number: 20240304344
    Abstract: A nuclear reactor with forced-convection liquid coolant and solid fuel assemblies incorporates a heat removal system using a liquid metal bath for removing the nominal heat and phase-change material(s) (PCM) for removing the decay heat in an accident situation. The solid-fuel nuclear reactor with liquid metal or molten salt primary coolant simultaneously ensures heat removal by forced convection in the primary circuit, in normal and accident operating modes, during shutdown through the primary vessel of the reactor, that is, beyond the second containment barrier. In the event of an incident or accident, a compact passive decay heat removal system is capable of performing the safety function for a predetermined period, typically three days, without any intervention by an operator, due to the presence of one or more PCM(s) that store(s) the decay heat produced in the core and removed by the primary vessel.
