2012:50 Fatigue Margins for Austenitic Stainless Steels in ASME Boiler and Pressure Vessel Code – A Literature Study
Knowledge about the margins against fatigue failure in nuclear piping systems is essential. Therefore, the margins in the ASME Boiler and Pressure Vessel Code (section III) fatigue design procedure for austenitic steels, type 304/316, as applied to real components have been investigated in this literature study. It is concluded that the current knowledge about the margins in ASME for...

2012:01 Kontrollrumskonstruktion – Samverkan mellan olika aktörer under konstruktion av nya och moderniserade kontrollrum
SSM har under senare år ställt högre krav på konstruktion och utformning av kärnkrafts-anläggningarna. Detta tillsammans med kärnkraftsindustrins uppgraderingar av effekten har medfört ett stort antal anläggningsändringar. En del av dessa anläggningsändringar har påverkan på kontrollrum och manöverutrustning samt på...

2013:09 An Application of the Functional Resonance Analysis Method (FRAM) to Risk Assessment of Organisational Change
The objective of this study was to demonstrate an alternative approach to risk assessment of organisational changes, based on the principles of resilience engineering. The approach in question was the Functional Resonance Analysis Method (FRAM). Whereas established approaches focus on risks coming from failure or malfunctioning of components, alone or in combination, resilience engineering...

2012:16 El och kontrollutrustning i kärnkraftverk. Problematik vid utbyte av åldrad utrustning
Studien visar på ett flertal områden som bör beaktas både hos tillståndshavarna och för framtida tillsynsstrategier för SSM. Flera av områdena har betydelse för säkerheten. Till exempel så framgår att konstruktionsprocessens efterlevnad och genomförande är mycket viktig för säkerheten. Genom att el- och kontrollutrustningen...

2012:70 Process Parameters Affecting Inhomogeneity of Material Microstructure
There’s been a tremendous change in the number, product types, locations, equipment, and manufacturing capabilities of stainless steel producers from the late 1960’s to present. This reconfiguration of the global steel industry occurred between the early 1970’s to the mid 1980’s and continues today. These changes have produced a loss in manufacturing flexibility, due to the inherent...

2012:07 Implementation of the Master Curve method in ProSACC
Cleavage fracture toughness data display normally large amount of statistical scatter in the transition region. The cleavage toughness data in this region is specimen size-dependent, and should be treated statistically rather than deterministically. The Master Curve (MC) methodology is a procedure for mechanical testing and statistical analysis of fracture toughness of ferritic steels in the...

2012:03 The IAEA Integrated Regulatory Review Service Mission to Sweden in February 2012
The Swedish Government decided on January 22, 2009 to mandate the Swedish Radiation Safety Authority, SSM, to apply for an international review of the Author-ity and its areas of supervision, an ‘IRRS’ (Integrated Regulatory Review Service) carried out by the International Atomic Energy Agency (IAEA). On February 25, 2009, SSM made a formal request to the IAEA for an IRRS in Sweden. The time...

2015:20 Guide for thyroid monitoring in the event of release of radioactive iodine in a nuclear emergency
This report aims to serve as a guide in the execution of a thyroid monitoring program during the intermediate phase of response to a nuclear emergency. Calibration factors for some instruments verified in the framework of the Nordic project THY- ROID (Nyander P. 2014) are listed here as an example. For different times after the intake, we present in this guide the measured values in net count...

95:63 Säkerhets- och strålskyddsläget vid de svenska kärnkraftverken 1994-95
Enligt proposition 1990/91:88 om energipolitiken skall regeringen varje år i budgetpropositionen redovisa drifts- och säkerhetsförhållanden vid de svenska kärnkraftreaktorerna. Regeringen har i regleringsbrevet uppdragit åt SK! att, i samarbete med Statens strålskyddsinstitut (SS!) årligen senast den 15 november till regeringen redovisa säkerhetsoch...

1995:60 Reliability of Piping System Components -Volume 3: A Bibliography of Technical Papers and Reports Related to Piping Reliability
Reflecting on older analysis practices, passive components failures seldom receive explicit treatment in PSA. to expand the usefulness of PSA and to raise the realism in plant and system models the Swedish Nuclear power Inspectorate has undertaken a multi-year research project to establish a comprehensive passive components database, validate failure rate parameter estimates and model...
