This paper proposes a "Precision-Uncertainty-Reliability" (PUR) collaborative assurance system, which achieves systematic improvement in detection performance through a multi-physics field coupling model, an improved uncertainty quantification method, and a Bayesian dynamic Probability of Detection (PoD) model. In the application of the HuaLong Pressurized Reactor 1000(HPR1000) reactor pressure vessel, the ultrasonic testing error was reduced from 7.2–1.8% (a 75% improvement in precision), and the defect detection capability ( \(\:{\text{a}}_{\text{90/95}}\) ) was improved from 1.85 mm to 0.92 mm (meeting the Level 1 nuclear safety standard). The PUR system provides technical support for the safe operation of nuclear facilities and lays a theoretical foundation for the development of NDT technology for Generation IV nuclear power plants.
