2011:02 The Back-End of the Nuclear Fuel Cycle in Sweden, Considerations for safeguards and data handling
The report is a compilation report consisting of three papers. A safeguards approach for the planned encapsulation facility and the operating final repository is presented in paper 1. Special considerations concerning safeguards for the final disposal process have been discussed and incorporated into the approach. Paper 2 defines the spent fuel data that must be secured, for safeguards...

2008:33 Risk-informed assessment of defence in depth, LOCA example
The methods that are used today in PSA are applicable for evaluating defence-in-depth levels 1 and 2. Failure data can be determined through: human reliability analysis, riskinformed in-service-inspection methodology, system reliability analysis and directly from plant specific failure data for the components. Many DID activities against LOCA are not explicitly modelled in typical...

2007:16 Hantering av händelser, nära misstag
Resultaten från kartläggningen visar att det finns många som använder olika typer av rapporteringsverktyg men inget speciellt för just ”nära misstag”. En slutsats är just att man inte ska behöva rapportera olika saker i olika system. En annan slutsats är att rapporteringssystemet behöver vara lättillgängligt. Användarna ska kunna...

2008:04 Driftklarhetsbeslut i kärnkraftanläggningar - Vilka faktorer påverkar beslutsfattandet?
Med anledning av avregleringen av elmarknaden i slutet av 1990-talet och den ökade fokuseringen å ekonomi och effektiviseringar av verksamheterna vid de kärntekniska anläggningarna i Sverige lät SKI genomföra en studie av hur tillståndshavarna Ringhals AB, OKG Aktiebolag och Forsmarks Kraft AB integrerar ekonomi och säkerhet i sina ledningssystem (SKI Ra...

2007:18 Marvikenreaktorn - ett industripolitiskt utvecklingsprojekt i otakt med tiden
Den statliga Atomenergiutredningen tillsattes 1955 och publicerade sin rapport i början av 1956. Med utgångspunkt från diskussionerna inom utredningen offentliggjorde Vattenfall samtidigt planer på två reaktorprojekt Adam och Eva. Det statligt finansierade forsknings- och utvecklingsföretaget AB Atomenergi (föregångare till nuvarande Studsvik AB) presenterade...

2007:23 On Safety Management, A Frame of Reference for Studies of Safety Management with Examples From Non-Nuclear Contexts of Relevance for Nuclear Safety
The authors present the theoretical framework. There they also discuss the pros of using the system perspective to build a useful frame of reference of safety management using non- nuclear organizations; this as a way to create models useful for the nuclear power industry but based on general understanding of the concept of safety management. The chosen organizations are used extensively to...

2021:09 Mechanisms important for material modelling in weld residual stress analysis
SSM perspective Background The prediction of weld residual stresses (WRS) is very complex as many mechanisms and phenomena influence the development of WRS during welding. For accurate prediction, the constitutive material models used are essential and must be able to describe the material response of the weldment constituents. For example, selection of a material model should only depend on...

2021:10 Establishment and use of attention values in environmental fatigue assessments
SSM perspective Background As Swedish NPPs reach their original technical design life, re-assessment of the fatigue life of structural components is needed for safe long term operation (LTO). In these re-assessments one must consider that new knowledge has shown that environmental effects on fatigue life must be considered. One common method to verify the fatigue life of structural components...

2022:18 Data report – sampling of sea water and marine organisms outside Ringhals NPP
SSM perspective Background The Radiation Safety Authority (SSM) funded the collection of marine biota over an annual cycle at the Ringhals nuclear power plant (NPP) to enable development of analytical methods for C-14. Methods for the C-14 analysis and results in the form of levels of C-14 in various marine organisms have been reported by the Swedish Defense Research Institute (FOI) in FOI...
