Optimization Design Based on Human Factors V&V of Human System Interfaces in Nuclear Power Plant

Abstract

The main control room, the monitor and control center of nuclear plant, integrates quantities of Human System Interfaces (HSIs), with which, the operators maintain the plant running safely and effectively under different working conditions[1]. Human Factors Verification and Validation (HF V&V) is one of the twelve elements of a Human Factor Engineering (HFE) program according to NUREG-0711. Research on V&V methods has been carried out for years, however, the V&V implementation in domestic nuclear power plants looks forward to being consummated. For HPR1000, the third generation of nuclear power technology with China’s self-owned independent intellectual property right[2], HF V&V activities include HSI HFE Design Verification (DV), HSI Task Support Verification (TSV), Partial Validation (PV), Integrated System Validation (ISV) and Human Engineering Discrepancy (HED) management. The V&V methods introduced in this paper gives an executable and effective way to evaluate whether the design conforms to HFE design principles and that the adequacy of the HSIs enable plant personnel to successfully perform their tasks and other operational goals, assuring plant safety. With these methods, plenty of suggestions based on the HEDs generated from different V&V activities are applied into the design of HSIs, and afterwards, an optimization for the main control room of HPR1000 will be achieved.
