Cell K SMR (Small Modular Reactor) nuclear pressure vessel welding cell is the modular reactor component fabrication configuration extending Cell A pressure vessel baseline (per Batch 19 #1) to serve the emerging SMR reactor supply chain — supporting reactor pressure vessel (RPV) + steam generator + pressurizer + main coolant piping + core internal fabrication for factory-built modular reactors from NuScale (US) + Rolls-Royce SMR (UK) + GE-Hitachi BWRX-300 + X-energy Xe-100 + TerraPower Natrium + Westinghouse AP300 + Chinese ACP100 Linglong One + Korean SMART. SMR reactors (30-300 MWe) differ from traditional 1000+ MWe reactors: (1) factory serial production vs field-fabricated one-of-a-kind; (2) modular transportable vs site-built; (3) shorter build cycle 3-5 years vs 8-12 years; (4) enhanced passive safety. Nuclear-grade welding remains ASME Section III (per Batch 28 #4) + NRC 10 CFR 50 + RCC-M compliant. This guide is the SMR Cell K nuclear welding configuration reference.
