Development of Human Factors Awareness for Criticality Safety Specialists at Westinghouse Nuclear Fuels - 14223
- Westinghouse - Springfields Fuels Limited, Springfields, Salwick, Preston, Lancashire, PR4 0XJ (United Kingdom)
Although human factors assessment typically involves specialist expertise, it is considered that enhanced local knowledge of this area for criticality safety specialists supports the incorporation of human factors consideration into tasks such as safety assessment, design and hazard reviews, development of operational and engineered criticality controls, training, incident investigation and emergency response. At the Westinghouse Springfields Fuel Manufacturing Site in the United Kingdom, specialist human factor support has been engaged to identify key competencies and training plans for criticality safety specialists. In addition, discussions have been held with the UK's Office for Nuclear Regulation (ONR) to outline the proposal and to discuss the approach. Following completion of an internationally recognised human factors training course the learning is now being applied by criticality safety specialists. Recent examples of learning applied include: 1) Review of past events and incidents to support the consideration of operator/equipment interfaces, leading to improved designs and processes. 2) Identification of critical tasks and the level of human factor assessment that is likely to be required. To support this, guidance has been produced by the criticality section for staff and contractors performing criticality safety assessments. 3) Assessment of the 'aims and operability' of engineered and procedural controls derived as part of the criticality safety assessment process. This involves participation of plant management and operators. 4) Consideration of human factors in emergency response activities such as infrequent tasks and tasks being undertaken under time pressures etc. This has been examined in recent emergency exercises and in the development of a recent criticality exercise scenario. 5) Criticality training has been reviewed with Plant Management, focussing on the methods utilised to deliver training (e.g. classroom based, computer training, on plant walk-downs); the aims and scope of training and how understanding is validated. 6) The link between criticality safety assessment and how the operations are / will be conducted has been reviewed as part of formal and informal criticality meetings and inspections. A key aspect of this is the criticality specialist's interaction with both plant management and operational staff. The development of human factors awareness into the criticality safety specialist's competency framework continues to be developed at Westinghouse but real benefits to criticality safety are already being demonstrated by this approach.
