As the brain of Nuclear Power Plant (NPP), Main Control Room (MCR) is an integrated system which comprises varieties of Human System Interfaces (HSIs), procedures, operators and environment. HSI is the medium that the operators monitor and control the Nuclear Power Plant. To improve the operating performance and avoid human errors, Human Factor Engineering (HFE) is required to be implemented in the new plant HSI design for plant safety. HPR1000 has followed the NUREG-0711 as the guidelines of HFE program, in which 12 elements are included. Task Analysis (TA) and Human Factor Verification & Validation (HF V&V) are two important elements for the HSI design. For task analysis, the design engineers could analyze the human actions (HAs) to identify the tasks that the operators must perform to accomplish the plant functions. Task analysis identifies not only the specific tasks needed to accomplish HAs but also the information, and controls required to complete those tasks which are considered as important input for the MCR HSI design. HF V&V is one of the final stages of the Human Factors Services as included in NUREG-0711. The HF V&V objective is to evaluate that the HSI design conforms to HFE design principles and that the adequacy of the interfaces enable plant personnel to successfully perform their tasks and other operational goals, assuring plant safety. The V&V element consists of four major activities: Sampling of Operational Conditions, Design Verification, Integrated System Validation, and HED Resolution. For different targets, Design Verification could be separated into two kinds of activities: HSI Task Support Verification (TSV) and HFE Design Verification (DV). TSV is an evaluation to verify that the HSI supports the requirements of personnel tasks, as defined by task analyses. The HAs, controls and information identified in task analysis could be used as the basic input for HSI TSV. To provide adequate input for the HSI design and TSV, the operational conditions of task analysis should be sampled as many as possible to cover all the typical conditions, which include normal conditions, transients, Design Based Accidents (DBA), Beyond Design Based accidents (BDBA), even severe accidents. The sampled conditions for task analysis would be available for the task support verification of the related HSIs. In conclusion, the task analysis could be used as the design input for HSI, while the task support verification could review the designed HSI with the output information from TA. This paper addresses the research and engineering implementation methodologies for task analysis and HSI task support verification. As the first reactor of HPR1000, HFE program have been carried out in Fuqing 5&6 MCR from preliminary design to final test. The Fuqing 5&6 TA and TSV achievements for MCR HSIs design are summarized in the paper.

Task analysis identifies the specific tasks needed to accomplish human actions, and the information, control and task support required to complete those tasks. In the control room design, the functions allocated to personnel shall be performed analysis, and it is identified that the specific task can be accomplished by the personnel. Task analysis can provide one of the bases for the human system interface design decisions; match human performance requirements with human capabilities; provide input to procedure development and provide input to staffing, training, and communications requirements of the plant. The method about task analysis and the screening methodology used to select the tasks for analysis are very important. Usually, the scope of task analysis is divided into two complementary activities: function-based task analysis and traditional task analysis, or operational sequence analysis. Function-based task analysis is the functional decomposition (goal-means analysis) for normal power operations. The traditional task analysis, or operational sequence analysis is developed for a representative set of operational and maintenance tasks. The operational sequence analysis include OSA-1 and OSA-2.The task analysis considers alerts, such as alarms and warnings, decision-making, response, teamwork and communication, workload task support, workplace factors, situational and performance shaping factors and hazard identification. The paper also describes the selected basis of selecting the operational sequence to be analyzed in the operational sequence analysis. The method about task analysis and the screening methodology used to select the tasks for analysis are very important. The objective of task analysis review is to verify that the applicant undertook analyses identifying the specific tasks needed to accomplish personnel functions, and also the alarms, information, control- and task-support required to complete those duties. The paper mainly describes not only the above content, but also the reviewing work about task analysis and questions found in reviewing. In this article, there are some examples about the function-based task analysis. At last, the verification for task analysis is addressed simply.

System Interfaces

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.

The study was conducted to know whether bulk inflow of Non Emergency Calls (NECs) acts as an independent predictor for depression in call handlers of Rescue 1122, Punjab, Pakistan. Forty five (45) call handlers were recruited from evening shift of 9 districts. Similarly, same-sized control group was made out of field rescuers. The groups were compared for rate and severity level of depression using Beck’s Depression Inventory-II (BDI-II; Beck, Steer, & Brown, 1996). Probable predictors (except workplace stress) for depression in call handlers were evaluated through risk estimates. For workplace stress, a purposefully developed close- ended Workplace Stress Questionnaire including two subscales i.e. Non Emergency call and Control Room Environment of 30 items each was administrated. Twenty nine (64.4%) subjects of study group reported depression on BDI. Consequently, the same group had significantly higher mean depression score than control (18.2 vs. 12.6; p = .00). The scores also showed insignificant association with any of the probable predictors (demographic variables) of the call attendees. The respondents perceived more occupational stress against NECs. The findings attract the attention of authorities towards the severity of the concern.
