00:26 Operator Performance in Non-Destructive Testing: A Study of Operator Performance in a Performance Test
typically performed with non-destructive testing (NDT). In NDT the task of the operator is to (based on diagnostic information) decide if the component can remain in service or not. The present study looks ... Murgatroyd, 1994 (see Enkvist, Edland, & Svenson, 1999, for a richer description)). Most research in this field concern equipment aspects. The aim of the research has been to increase the capability of the system...

2016:04 Uncertainty assessment of the SCANAIR V_7_5 computer program in analyses of BWR reactivity initiated accidents
V_7_5 computer program. The work is intended to supplement a similar uncertainty assessment, focussed on pressurized water reactor accidents, which is currently being organized as an international benchmark ... In case cladding dry-out occurs, the models for clad-to-coolant heat transfer have a large impact on the calculated results, not only for cladding temperature, but also for cladding deformations and fuel...

2012:50 Fatigue Margins for Austenitic Stainless Steels in ASME Boiler and Pressure Vessel Code – A Literature Study
are scarce in the literature. It is concluded that data for fully reversed constant amplitude load on small smooth specimens are unable to provide reliable information about the fatigue margins in a real ... and displacement control become important even in high cycle fatigue, thus having significant impact on margins. There is a clear need to investigate the transferability of the ASME data to fatigue in real...

00:06 Accident Analysis and Barrier Function (AEB) Method. Manual for Incident Analysis
HPES, but differs from that method in different ways. To exemplify, the AEB method has more emphasis on technical errors than HPES. In contrast to HPES that describes a series of events, the AEB method models ... analyses. However, the AEB method is a generic and stand-alone method that has been applied in other fields than nuclear power, such as, in traffic accident analyses. Sammanfattning [[Summary in Swedish]]...

02:22 An Analysis of the Authorities' Expected Costs Related to the Decommissioning Programme (pdf 271 kb)
pro-active work by applied studies on some major cost items. One central criterion for these studies is that the studied cost item, or cost items, shall have a significant impact on the funding and/or guarantees ... cost has up to now been based on deterministic data from joint work within SKI and SSI. The deterministic origin has been a major drawback, since SKB calculates costs based on probabilistic figures. A new...

2006:10 Models for MOX fuel behaviour - A selective review
SKI Perspective Nuclear fuel containing mixed oxide (MOX) pellets have been used since the 1960´s. MOX fuel pellets are made from a mixture of uranium and plutonium oxide. MOX allows the large quantities ... natural uranium are the Pu-producing U-238. In fact, programs for using MOX were developed in the 1970´s to meet the feared or anticipated scarce supply of uranium at moderate prices. Although uranium prices...
