2014:09 Further Development of the Core Simulator CORE SIM: Extension to coupled capabilities for BWRs
to coupled capabilities for BWRs 2014:09 Authors: V. Dykin A. Hernández-Solis C. Demazière SSM perspective Background Noise analysis and diagnostics is of prime importance for an early detec- ... fluctuations in neutron flux in PWRs/BWRs. This first model was based on solving two-group diffusion equations in 2 dimen- sions. Later on, in 2011, CORE SIM was modified in order to be able to handle three...

99:10 Verification and Validation of HumanFactors Issues in Control RoomDesign and Upgrades
Human factors work may therefore be required. There is an extensive literature on human factors itself, but not so much on how it is verified and validated. Therefore, HRP and the Swedish Nuclear Power ... (SKI) commissioned a study. The objective was to review the literature and establish a knowledge base on verification and validation (V &V) of human factors issues. The report first discusses verification...

2017:25 Evaluation of weld fatigue reduction in austenitic stainless steel pipe components
Anderson SSM 2017:25 SSM 2017:25 SSM perspective Background The performed investigation is a continuation of the work performed in SSM 2015:38 where fatigue tests were performed on pressurized ... with mainly reversed bend- ing deformation and particular focus on high cycle fatigue. The previous fatigue results were quite dependent on the estimation of the stress con- centration factor of the weld...

00:57 Application of the Pin-Loading Tension Test to Measurements of Delayed Hydride Cracking Velocity in Zircaloy Cladding
specimens made from pressure tubes of Zr2.5Nb alloy, an alloy in which DHC failures have occurred in the field. This round robin was a great success since all participants got very similar values of the crack ... fuel failure mechanism SKI has already supported a doctoral student project on DHC at KTH and an extensive theoretical review on DHC by the consultancy ANT. It is clear that this aspect of DHC also has to...
