Analysis of the Technological Evolution of Materials Requirements Included in Reactor Pressure Vessel Manufacturing Codes

The growth of green energy technologies within the frame 7th Sustainable Development Goal (SDG) along with concern about climatic changes make nuclear an attractive choice for many countries to ensure security and sustainable development as well actively address environmental issues. Unlike equipment (immovable goods), which are often well-catalogued analyzed, design manufacturing codes their standardized materials specifications can be considered movable intangible goods that have not been thoroughly studied based on a detailed evaluation scientific technical literature reactor pressure vessel (RPV) behavior. aim this work is analysis historical advances in properties research associated requirements. analysis, consolidated U.S. Nuclear Regulatory Commission (NRC) Guide (RG) 1.99 Rev.2 model, enables determination best options, corresponding some most widely used material such WWER 15Kh2MFAA (used from 1970s 1980s; already operation), ASME SA-533 Grade B Cl.1 pressurized water reactor-PWR 2nd–4th; DIN 20MnMoNi55 22NiMoCr37 PWR 2nd–4th) ASTM A-336 F22V (current designs). Consequently, view results obtained, it concluded options correspond recently developed or well-established reactors. These assessments endorse fact technology continually improving, safety being its fundamental pillar. In future, further related heritage evolution requirements other clean power generation will performed.
