  • 2013:27 Numerical simulations of headed anchors break in reinforced and non-reinforced concrete structures

    The design codes for anchorage of equipment in concrete structures have been developed since the time the Swedish power plants were designed. Furthermore, the design basis has been updated and in some cases new mechanical loads have been added. As a consequence, it can be difficult for some anchorages to meet the requirements of today. In the design of anchorage equipment the beneficial effect...

  • 2014:18 Evaluation of the Halden IFA-650 loss-of-coolant accident experiments 2, 3 and 4

    The analytical tools, which are fuel rod computer codes, that Quantum Technologies AB use and develop, contain models of several of the phenomena that are acting on the nuclear fuel (cladding temperature, fission gas driven pressure, strain and stress in the cladding, rod rupture, etc.) and how the separate effects interact in the complex integrated manner. The codes are under constant...

  • 2014:09 Further Development of the Core Simulator CORE SIM: Extension to coupled capabilities for BWRs

    The developed tool is fully MatLab based and requires a set of input data from a commercial static core simulator. The driving perturbation can be specified both as a perturbation in thermo-hydraulic parameters or directly as a perturbation in macroscopic cross-sections. As output, the 3-dimensional spatial distribution of the noise in coolant density, pressure, enthalpy, inlet velocity, fuel...

  • 2019:13 Organisatoriska risker avseende strålsäkerhet i ekonomiskt pressade lägen

    SSM perspektiv Bakgrund Kärnkraftsbranschen befinner sig i en ekonomiskt pressad situation. Höjda säkerhetskrav, åldrade anläggningar som kräver mer underhåll och låga elpriser leder till att resursanvändningen måste maximeras. Stora projekt pågår hos tillståndshavarna i syfte att effektivisera organisationerna. Nedskärningar...

  • 2019:23 Participation in the European Committee for Standardization's workshop regarding civil structures

    SSM perspective Background During the period 2014-2018, a CEN1 workshop (Phase 2 Prospective Group 3 civil works) have been carried out. The aim of the workshop is to provide a base founded on the French standard in order to be able to establish a possible future European standard for the design of civil structures at nuclear power plants. The workshop has identied which additional...

  • 2019:20 Assessment of structures subject to concrete pathologies (ASCET), phase 3

    SSM perspective Background ASCET is an international research project initiated by WGIAGE1 OECD2 / NEA3. WGIAGE Concrete subgroup is a working group within the OECD / NEA whose task is to address issues concerning the maintenance of the integrity of concrete structures, proposals for general principles to optimally handle the challenges of integrity, especially with regard to ageing of...

  • 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...

  • 2010:41 Rock-block configuration in Uppland and the Ålands-hav basin, the regional surroundings of the SKB site in Forsmark, Sea and land areas, eastern Sweden

    This report concerns a study which was initially conducted for the Swedish Nuclear Power Inspectorate (SKI), which is now merged into the Swedish Radiation Safety Authority (SSM). The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the SSM. The topography in Uppland is more broken in the sea area east and northeast of...

  • 2001:36 Kartläggning av strategiskakompetensbehov för kärntekniskverksamhet i nuläget och för framtiden

    SKI skall, på uppdrag av regeringen, före utgången av år 2001 redovisa en uppdaterad strategi för sin framtida inriktning på forskningen och som ett led i detta arbete bedöma det framtida nationella kompetensbehovet och hur detta skall tillgodoses. ES-konsult har i detta sammanhang av SKI fått uppdraget att - genom en till industrin och säkerhetsmyndigheten...

  • 2013:12 Multivariatanalys av radioaktivitetsdata dels från utsläpp till luft och vatten från OKG och Clab dels i omgivningen av Oskarshamn

    De svenska kärntekniska anläggningarna genomför regelbundet mätningar av utsläppt radioaktivitet till luft och vatten samt mätningar av radioaktivitet i olika provslag i omgivningen. Omgivningskontrollen genomförs enligt ett program framtaget av dåvarande Statens strålskyddsinstitut, nuvarande Strålsäkerhetsmyndigheten (SSM). Det nuvarande...
