• 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

• 2017:35 Review of paleo-, historical and current seismicity in Sweden and surrounding areas with implications for the seismic analysis underlying SKI report 92:3

  Abstract The report contains a review of the current state of knowledge on Swedish paleoseismic events, as well as information on the Swedish earthquake catalogue updated to early autumn 2016 and the revised Nordic earthquake catalogue (Fencat). It includes a section on the possibilities to

• 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.

• 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,

• 2017:25 Evaluation of weld fatigue reduction in austenitic stainless steel pipe components

  Background The performed investigation is a continuation of the work performed in SSM 2015:38 where fatigue tests were performed on pressurized welded austenitic stainless steel piping components. The specimens were subjected to a realistic variable amplitude loading with mainly reversed

• 2017:23 Kalibrering för bestämning av optimal beräkningsmodell

  Bakgrund SSM bedömer i tillsynen avancerade datorberäkningar relaterade till drift av kärnkraftverk, utförda av extern part. Inom kärnkraft kan experimentella undersökningar vara olämpliga. Beräkningar blir därför ofta det enda alternativet att undersöka

• 2017:22 Effect of weld repairs on residual stresses in nickel base dissimilar metal welds

  Background The driving force for crack growth near welds in nuclear application piping may arise from weld residual stresses. Experience from nondestructive examination show that cracks in dissimilar metal welds are often found near weld repairs. The repair welding may affect the residual

• 2017:21 Neutronfluensberäkningar för surveillance provning

  Sammanfattning Bestrålning av reaktortankens material med snabba neutroner leder till förändringar i materialets egenskaper så att det försprödas. De förändrade materialegenskaperna utgör en av de viktigaste orsakerna till att reaktortankens livslängd

• 2017:20 Assessment of inertia effects on transient clad-to-coolant heat transfer and coolant flow under reactivity initiated accidents

  In this report, simple hydrodynamic models are used for studying the effects of coolant inertia on fuel-to-coolant heat transfer and coolant flow under reactivity initiated accidents in light water reactors. The objective is to assess if the inertia effects are important enough to warrant
