Nuclear power covers nuclear island (reactor, steam generator, main coolant pump) and conventional island (turbine, generator). Extreme demands: high temperature (350°C+), radiation hardening (10 MGy) and 60+ year life. Framatome, AREVA, Westinghouse, Siemens Energy (conventional), KSB (nuclear pumps). ASME III, RCC-M and KTA are compliance standards.

FAQ
Q Nuclear-grade vs commercial parts?
A
Nuclear class (K1/K2/K3) per ASME III or RCC-M with ASNT NDT, material traceability to melt heat, continuous witnessing — 5-20x cost. Conventional island can use industrial-grade.
Q Post-Fukushima upgrades?
A
PWRs add passive emergency cooling (IRWST), 0.3g seismic, 168-hour backup diesels and severe-accident management (SAMG). New builds (EPR, AP1000, HPR1000) include these by default.
Q Chinese nuclear export to Germany?
A
ASME N-stamp, KTA certification and RCC-M (for France export) mandatory; CCC does not apply to nuclear. HPR1000 has cleared UK GDA review.
