2010 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

Challenges to the operating nuclear power plants and transport infrastructures are outlined. It is concluded that most aggravating factors are related to knowledge. Thus, of necessity, effective knowledge management is required.

Knowledge management theories are reviewed in their historical perspective as a natural extension and unification of information theories and theories about learning. The first line is identified with names as Wiener, Ashby, Shannon, Jaynes, Dretske, Harkevich. The second line – with Vygotsky, Engeström, Carayannis.

The recent developments of knowledge management theorists as Davenport, Prusak, Drew, Wiig, Zack are considered stressing learning, retaining of knowledge, approaching the state awareness of awareness, and alignment of knowledge management with the strategy of the concerned organizations.

Further, some of the details and results are presented of what is achieved so far. More specifically, knowledge management tools are applied to the practical work activities as event reporting, data collection, condition assessment, verification of safety functions and incident investigation. Obstacles are identified and improvements are proposed.

Finally, it is advised to continue to implement and further develop knowledge management tools in the organizations involved in various aspects of safety critical facilities.

Abstract [sv]

Utmaningar som kärnkraftverken och transportinfrastrukturer står inför har kartlagts. Kartläggningen pekar på att problemen är relaterade till brister i kunskap. Det är därför nödvändigt att fokusera på kunskap och implementera kunskapsmanagement med däri ingående teorier.

Sådana teorier beskrivs i ett historiskt perspektiv. Det framgår att kunskapsmanagement har flera rötter av vilka de viktigaste är informationsteorier och teorier om inlärning. Den första är associerad med namn som Wiener, Ashby, Jaynes, Dretske, Harkevich. Den andra med namn som Vygotsky, Engeström, Carayannis.

Även bidrag från moderna tänkare inom kunskapsmanagement som Davenport, Prusak, Drew, Wiig, Zack utvärderas för att förstå hur de involverade organisationerna kontinuerligt kan lära sig, bevara kunskap, nå medvetande gällande kunskap och integrera kunskapsmanagement med företagsstrategier.

Vidare så presenteras ett urval av resultat för att illustrera vad som har åstadkommits hittills. Kunskapsmanagement-teorier appliceras på verksamheter som erfarenhetsrapportering, databaser, provning, verifiering av säkerhetsfunktioner och utredning av incidenter. Kunskapsmanagement gör det möjligt att identifiera och beskriva brister i de etablerade verksamheterna och att föreslå förbättringar.

Rekommendationen för framtiden är att fortsätta arbetet med implementering och vidareutveckling av kunskapsmanagement för applikationer som är relevanta för kärkraftverk, transportinfrastrukturer och andra säkerhetskritiska anläggningar.

Abstract [en]

To this date, strategies aiming at a safe operation of nuclear power plants focused mainly on the prevention of technological breakdowns and, more recently, on the human attitudes and behaviors. New incidents and challenges to safety, however, motivated the nuclear community to look for a new safety approach. The solution became a strong focus on knowledge managemen tand associated theories and sciences as information theories, artificial intelligence, informatics ,etc. In all of these, the fundamental role is played by a category of information.

This work reviews a number of information interpretations and theories, among which of great relevance are those capturing the fundamental role information plays as a mean to exercise control on the state of a system, those analysing information communication between agent sinvolved in safety-related activities, and, finally, those which explore the link between information and the limits of our knowledge. Quantitative measures of information content and value are introduced. Completeness, accuracy, and clarity are presented as attributes of information acquired by the receiver. To conclude, suggestions are offered on how to use interpretations and mathematical tools developed within the information theories to maintain and improve safety of nuclear power plants.

Abstract [en]

Challenges to the safety of operating nuclear power plants due to ageing, power uprates, modernizations and a generational exchange in the workforce put a strong focus on knowledge. Both the nuclear regulators and the nuclear plants need to learn more about knowledge management inorder to better manage knowledge. This article aims to promote implementation of knowledge management by taking an example of a regulatory activity for event reporting and examining it in the context of knowledge management. The purpose of the examination is to improve the event reporting activity by studying credibility and usability of produced knowledge, means for its dissemination, specific objectives of consumers of knowledge and other important aspects that are formally emphasized by knowledge management. The most apparent insight that emerges from the examination is that the established event reporting practice is very strong in collection and communication of data about unsafe events but is weaker in creation and sharing of knowledge.

Abstract [en]

The incident in Forsmark nuclear plant in 2006 can be seen not merely as a failure of technology or safety culture but as a failure of knowledge. A previous study of the chain of events that led to the incident revealed that the recent modernization activities in the plant had lead to striking gaps in knowledge and introduction of flaws. This article aims to analyze the exact mechanisms underlying breakdowns in knowledge and to suggest how to prevent re-occurence. The Shannon’s communication theory and the activity theory are used for the purposes.

Abstract [en]

Previous studies of the Forsmark incident from 25 July 2006 emphasised a need to improve integration and communication between the nuclear plants and the operating company of the power grid. This paper aims to better understand why communication issues occurred and what improvements are needed. For these purposes, communication issues were analysed in the context of knowledge management, more specifically communication theories and activity theory. In particular, the historical background and the role of adverse events are studied.

Abstract [en]

Although safety is and has always been the primary objective for the nuclear community, it happens that the established practices for verification of nuclear plants' safety systems fail to provide reliable knowledge. The traditional investigation techniques have proven to be insufficient in their attempts to solve the problems and to prevent new failures. In this paper, difficulties in performing reliable verifications of safety systems are viewed through a lens of knowledge management. The focus is on a transformational development of knowledge from the currently accepted knowledge through acquiring a new knowledge. It is suggested that knowledge activities should be established in the plants for all safety systems to ensure allocation of necessary resources for reliable knowledge.

Abstract [en]

Providing safety of reinforced concrete containments is one of the main challenges of the nuclear industry. This is because:

• Concrete degradation, decreasing compressive, tensile and yield strengths, macro- and micro- cracks, fatigue cracks, de-bonding reinforcement, spallation and porosity reduce the fracture toughness, change the magnitude and orientation of the main stresses, and decrease the load-carrying capabilities of structures.

• Dehydration of cement stone, due to temperature, radiation, leaching of calcium hydroxide from the concrete, sulfate attack, alkali-aggregate reaction and subsequent swelling, is evaluated currently by traditional local NDE methods with low accuracy.

• Revealing corrosion location and determination of its type and danger level in reinforced or pre-stressed concrete containments is not performed on a regular basis.

• Movement of soil under the containment base is evaluated only when there are visible indications of damage.

The situation is even worse because existing Non-Destructive Inspection (NDI) methods provide limited information and are not suitable for revealing, identifying and assessment of flaws in structural elements of nuclear power plant containments. To solve the above-mentioned problems, the authors have created and successfully used for different applications the Quantitative Acoustic Emission Non-Destructive Inspection technology (QAE NDI). The results of the investigations presented below demonstrate the capabilities, advantages and limitations of QAE NDI technology for revealing, typifying, and assessing flaws and age-related degradation in nuclear power plant containments.

Abstract [en]

There are clearly many issues of concern for engineers, researchers, managers, politicians and other actors, involved in the complex tasks of operating transport infrastructures. These issues lead, with necessity, to a need to focus on managing knowledge. The purpose of this article is to promote adoption and continuous development of knowledge management theories for the sector of transport infrastructures. To fulfil this goal, this article relates knowledge management theories to the challenges that complicate safe and economic operation of the transport infrastructure facilities. The results offer the practitioners the framework for understanding benefits that result from implementation of knowledge management while illustrating re-examination of the established Swedish Transport Administration’s (STA) computer database, top-level strategic policies and a list of guidelines for implementation of knowledge management.
