HELC Advantages for ScCO2 Cycle Applications High pressure capability Bonded core assembly tested up to 5,000 psi High temperature capability Stainless steel core ; test coupons fabricated with Inconel 625 for higher temperature and corrosion resistance, Nickel coating enhances base stainless steel corrosion resistance Thermal stress capability Flexible insert structure to mitigate thermal shock transients Enhanced heat transfer Insert structures that enhance heat transfer with limited pressure drop impact Significantly lower cost Single core and manifold bonding step; LAB bonding process, where surface finish, furnace loading, process time are substantially reduced versus diffusion bonding; lower part count for same heat transfer; less material Configurational and capacity flexibility Modules of various widths and heights
