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]

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.
