The most frequent cause of faults in safety-critical real-time computer systems is traced to fuzziness in representing requirements knowledge. Pitfalls using a natural language as a medium for representing the system requirements knowledge were analysed and explored. To ensure the specified safety, it is necessary to represent the system requirements of safety-critical real-time computer systems using formal mathematical methods. This removes the fuzziness in communicating knowledge on reactor system requirements. This paper contains the formal mathematical model for requirement specifications of FBTR systems using Z notation. Finally, the advantages of using formal representation for representing system requirements knowledge of FBTR using Z notations to minimise the ambiguity in knowledge communication and thus improve the safety are summarised.","PeriodicalId":188437,"journal":{"name":"International Journal of Nuclear Knowledge Management","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133101404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In parallel, there is a need to make nuclear knowledge easily accessible to future generations. In addition to the knowledge in each member state, the European Commission (EC)'s Institute for Energy (IE) produced a long-standing record of results from its own institutional activities and even more through participation in a large number of European Network partnership projects. The IE has developed a method for the consolidation of nuclear knowledge which relies on the mobilisation of all identified leading experts in the European Union (EU) in reevaluating old knowledge and consolidating what is valuable to create training materials for new generations. This method was applied for a pilot study for consolidating and preserving Russian reactor-type (WWER, i.e., the Russian version of a pressurised water reactor) RPV safety-related knowledge, which is scattered in many countries and in different languages, facing a serious issue in terms of getting lost. The initiative of the IE is a small part of a wider nuclear knowledge preservation and consolidation challenge (think big), which will be elaborated and discussed in this paper, as well as the experience gained from the first pilot study (act small).","PeriodicalId":188437,"journal":{"name":"International Journal of Nuclear Knowledge Management","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130075168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If faults occur in NPPs, it is very difficult for a human operator to perform routine tasks, such as distinguishing normal from abnormal conditions and predicting future states, etc. In this paper, a fuzzy inference system is adopted for the diagnosis of abrupt faults in a nonlinear model of a typical Pressurised Water Reactor (PWR). The fuzzy system is tested with different shapes of Membership Functions (MFs). The if-then rules, representing the underlying processes, are inferred from the available fault-symptom relations. The symptoms are generated using plant model measurements.","PeriodicalId":188437,"journal":{"name":"International Journal of Nuclear Knowledge Management","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131051606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As many nuclear experts around the world are approaching retirement, the potential exists for the loss of a substantial amount of critical nuclear knowledge and corporate memory. The loss of such employees, many of whom literally designed, constructed and now operate existing nuclear power plants, poses a clear internal threat to the continued operations of these facilities. In addition, the loss of this knowledge and expertise could impact future plans for the construction of new, advanced nuclear units. This paper provides practical guidance on knowledge loss risk management. The guidance is based upon the actual experiences of IAEA member states' operating organisations and is intended to increase awareness of the need to develop an integrated and strategic approach to capture critical knowledge before it is lost. The specific objectives of the paper are to enable nuclear organisations to: (1) conduct knowledge loss risk assessments to identify specific knowledge loss threats, (2) evaluate the consequences of the loss of critical knowledge and skills, (3) develop action plans to retain this knowledge and (4) use this knowledge to improve the skills and competencies of new and existing workers.","PeriodicalId":188437,"journal":{"name":"International Journal of Nuclear Knowledge Management","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128396471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although these organisations have been involved in KM-related activities for some time, they typically have not viewed and managed these activities from a KM perspective. Several NPPs have been early adopters of KM practices in the nuclear industry and have been proactive in implementing company-wide KM programmes. However, at most NPPs, the concepts and benefits of KM are only beginning to be understood and have yet to be applied. Effective KM enhances a firm's capability to assimilate, create and exploit knowledge. KM is widely recognised in both the management literature and in practice as an important enabler of long-term organisational performance. Its role is particularly important in technology-intensive industries such as the nuclear power industry. This paper summarises the preliminary findings of research being done at Atomic Energy Canada Ltd. (AECL) to explore the link between KM practices and NPP organisational performance. These initial findings are based on a review of the literature and meetings with NPP managers during several nuclear power station visits. The research is being conducted in collaboration with the International Atomic Energy Agency.","PeriodicalId":188437,"journal":{"name":"International Journal of Nuclear Knowledge Management","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123394192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
