• 2007:27 Kompetensöverföring på svenska kärnkraftverk i samband med pensionsavgångar

  Rapporten visar att ett av Sveriges tre kärnkraftverk har ett program för kompetensöverföring. På de två som saknar program efterfrågas mer struktur inom området, även om man redan nu arbetar med mentorer eller handledare. Genomgående är upplevelsen av bristen på resurser för överrekrytering och tiden till att överföra.

• 2007:39 Influence of Crack Morphology on Leak Before Break Margins

  The SKI regulation SKIFS 2004:2 allows for the use of Leak Before Break (LBB) as one way to provide assurance that adequate protection exists against the local dynamic consequences of a pipe break. The way to demonstrate that LBB prevails relies on a deterministic procedure for which a leakage crack is postulated in certain sections of the pipe based on the leak detection capability of the...

• 2007:37 Identification of Common Cause Initiating Events Using the NEA IRS Database

  The study carried out within the framework of this project is a continuation of work conducted for SKI in 1998 on the identification of Common Cause Initiators based on operational events documented in the NEA Incident Reporting System (IRS). This project covered the events reported in the IRS database with the incident date in the period of 1980- 01-01 – 2006-11-15. The events of highest...

• 2007:04 Link Between RI-ISI and Inspection Qualification: Relationship between Defect Detection Rate and Margin of Detection

  A relationship has been established between defect detection ratio and margin of detection based on blind trails. The results are based on a rather small amount of data produced by personnel from one inspection laboratory but give us indications of how signal to noise ratio is possible to relate to the probability of detection (POD) used in RI-ISI models. The relationship need to be developed...

• 2007:14 Review of experimental data for modelling LWR fuel cladding behaviour under loss of coolant accident conditions

  This project has contributed to the research goal of giving a basis for SKIs supervision by means of evaluating experimental data and modelling the nuclear fuel cladding during a design base accident. The project has also contributed to the research goal to develop the competence about licensing of fuel at high burnup, which is an important safety issue. The results are useful as such, but...

• 2008:49 En studie av olycksutredningsmetoders utveckling: En sammanställning över “State-of-the-Art”

  Projektets syfte var att kartlägga de huvudsakliga olycksutredningsmetoder som utvecklats sedan början av 1990-talet. Motivationen är den ökande frekvensen av olyckor som sätter sig upp mot förklaringar i enkla termer, så som orsak-verkanskedjor eller mänskliga fel. Medan komplexiteten hos sociotekniska system är stadigt ökande i alla industriella...

• 2008:34 Utformning av larmsystem i svenska kärnkraftverk

  Det pågår flera stora moderniseringsprojekt inom den svenska kärnkraftindustrin. En del i dessa projekt består av att man helt eller delvis byter ut analoga informations- och manöversystem i kontrollrummen till digitala vilket förändrar larmsystemen. Digitala larmsystem har en mängd fördelar men kan också medföra risker och negativ säkerhetspåverkan.

• 2008:50 Study on Developments in Accident Investigation Methods: A Survey of the “State-of-the-Art”

  The objective of this project was to survey the main accident investigation methods that have been developed since the early or mid-1990s. The motivation was the increasing frequency of accidents that defy explanations in simple terms, for instance cause-effect chains or “human error”. Whereas the complexity of socio-technical systems is steadily growing across all industrial domains,...

• 2019:03 Evaluation of the hydrodynamic model in PARET/ANL

  Background The fuel rod analysis program SCANAIR has been developed by IRSN (Institut de Radioprotection et de Sûreté Nucléaire) for analysis of reactivity initiated accidents (RIA) in light water reactors. The Swedish Radiation Safety Authority (SSM) has access to SCANAIR in exchange for annual contributions for its further development. This ensures a possibility for SSM to do...
