2012:50 Fatigue Margins for Austenitic Stainless Steels in ASME Boiler and Pressure Vessel Code – A Literature Study
as illustrated by Figure 1. The design fatigue curves have been obtained from laboratory tests, i. e. the mean curve, by reducing the fatigue life at each point on the curve by a specified factor ... discrepancies are especially pronounced in what is commonly referred to as the high cycle fatigue regime, i. e. 10.000-100.000 number of cycles to failure or more. This will have an impact on the computed design...

2007:17 Spent Fuel Dissolution and Source Term Modelling in Safety Assessment
type of nuclide is relatively inert in groundwater with a limited interaction with solid phases e.g. I-129, Cl- 35. These nuclides are few in number and are only affected by the slow release from the fuel ... recommended IRFs and supporting data for the nuclides C-14, Cl-36, Se-79, Sn-126, Tc-99, Pd-107, I-129 and Cs-135. In general there are limited data in support of IRFs, since experimental work with...
