  • 2017:16 Stress intensity factor solutions for circumferential cracks in cylindrical bars under axisymmetric loading and global bending

    Background The case of a circumferential crack in a cylindrical bar has not been available in the ProSACC code. The need for such a geometry, especially considering nonlinear axisymmetric loading and global bending, has motivated the development of new stress intensity factor solutions, also known as K-solutions. These new K-solutions will be available in ISAAC, the successor to ProSACC.

  • 2017:12 Computational assessment of LOCA simulation tests on high burnup fuel rods in Halden and Studsvik

    Background Loss of Coolant Accidents (LOCA) are among the most demanding accidents that can happen in a Light Water Reactor (LWR). The lack of cooling and the drop in pressure impose large stresses on the nuclear fuel which would increase the risk of fuel rod damage and the subsequent release of active material. But LOCA is also an accident that the nuclear power plant is designed to...

  • 2017:29 Evaluation of the simulation software CIVA for qualification purpose

    Background Modeling is an important tool within NDT, partly to develop and optimize testing technologies, but also within the Qualification Body’s activities to assess technical verifications and perform parameter studies. SSM has supported university research in the area for many years and, among other things, in the development of a software for ultrasound modeling. In addition, the...

  • 2017:32 COMRAD – Comprehensive investigation of the performance of computed and digital radiography

    Background Within the industry, there has long been a need to replace the traditional X-ray film and its handling. These both for economic and environmental considerations. Both computed radiography and digital radiography offer many advantages over the traditional use of x-ray with film. However, the transition from film-based radiography requires in-depth knowledge of the relationship...

  • 2017:36 Topical Peer Review 2017 Ageing Management Swedish National Assessment Report

    Executive summary The European Union’s Nuclear Safety Directive 2014/87/EURATOM (NSD) requires the member states to undertake topical peer reviews (TPR) every 6 years with the first starting in 2017. The member states, acting through the European Nuclear Safety Regulators Group (ENSREG), have decided that the topic for the first topical peer review is ageing management. The Swedish Radiation...

  • 2016:37 PARTRIDGE project: Review and evaluation of the probabilistic fracture mechanics code PRO-LOCA

    Background The Swedish Radiation Safety Authority (SSM) and the Swedish nuclear power plant owners have financed Inspecta Technology in Sweden to evaluate the PRO-LOCA code. It is a computer code, developed by Battelle in the USA, in which the leak- and rupture probabilities of piping in nuclear power plants are analysed. The pipe systems may contain the damage mechanisms fatigue and/or...

  • 2016:40 Analys av signalsvar från simulerade bindfel

    Bakgrund Kvalificering av oförstörande provningssystem förutsätter att testblock som används vid praktiska demonstrationer innehåller tillverkade kvalificeringsdefek er med egenskaper som motsvarar de defekter som kan förekomma i aktuella anordningar. Bland annat behövs att dessa kvalificeringsdefek er ger relevanta signalsvar. De senaste åren har det...

  • Havsvatten

    Havsvatten provtas sedan 2006 inom det nationella miljö­över­vaknings­programmet. Många ämnen som släpps ut i miljön hamnar i haven på sikt. Haven fungerar både som transport­medium och utgör livs­miljön för många organismer som kan ta upp olika ämnen från vattnet. Mätningarna ingår också...

  • Laboratoriearbete med öppna strålkällor

    På många laboratorier inom forskning, veterinärmedicin och industrier används radioaktiva ämnen. Dessa ämnen hanteras ofta öppet i laboratorier på olika sätt. I Strålsäkerhetsmyndighetens föreskrifter kallas detta för arbete med öppna strålkällor.
