Abstract. Significant reductions in CO2 greenhouse gas emissions must be realized to meet the US goal of a 50% overall decrease by 2030. To further meet the net-zero emission goal by 2050, substantial reductions across three primary sectors (electricity, transportation, and industrial/buildings) must also be realized. Within the electricity sector, these significant reductions can only be accomplished through the replacement of much of the existing power generation infrastructure with renewables, hydrogen, natural gas, storage and new nuclear. It is anticipated that by 2050, the US will have to replace nearly 800GW of fossil and nuclear power generation assets (Note: 1GW = ~750,000 homes or 2 coal-fired power plants). This paper highlights several planned nuclear units (40 units) that are slated for production by the 2030 timeframe. If the PM-HIP community wants to be a part of this transition and support new nuclear, it too must begin work immediately to both qualify new materials/components and further develop its infrastructure for new component manufacturing and fabrication. This paper provides an overview of the current materials that are accepted within the ASME Boiler and Pressure Vessel Code and highlights recent changes which will allow PM-HIP materials/components to be more easily integrated and accepted into the Code. Additionally, this paper identifies many of the key needs for PM-HIP to be considered part of the new build equation including two enabling technologies: PM-HIP modeling & design and large PM-HIP capabilities, along with three additional supporting needs: powder production, scaling of components, and engagement of the end-user community.
