2005:11 Svensk kärnenergi – En exposé över lagstiftningen på kärnenergiområdet från andra världskriget till millennieskiftet
legislation regarding the production of nuclear energy in Sweden. When the atomic bomb was dropped on Hiroshima, it became apparent that enormous amounts of energy could be harnessed from uranium nuclei ... were and remain difficult to interpret. Nevertheless, certain political decisions were made based on these results leading to legislation prohibiting the Government from licensing new reactors, and...

2006:26 A Novel Experimental Set-Up for Improving the Sensitivity of SV Waves to Shallow Surface-Breaking Cracks
To this end, three cracks of depth approximately equal to 0.3 mm, 0.5 mm and 0.7 were introduced on the surface of steel samples with a thickness of 47 mm. These cracks were insonified with transducers ... or other defects on the component’s surface opposite to that on which the probe is placed. Nearly always, such waves are generated upon refraction of a longitudinal wave incident on the wedge-axle interface...

2005:16 Assessment of Core Failure Limits for Light Water Reactor Fuel under Reactivity Initiated Accidents
previously estimated. At the beginning of 1995 SKI issued fuel and cladding failure limits based on available test data. It was envisaged at that time that the failure limits should be re-evaluated ... joined the OECD-IRSN CABRI water loop project at the end of 2000. The purpose was to gain information on the failure threshold for nuclear fuel cladding as a function of burnup, especially for modern cladding...

02:29 Evaluation of the FRAPCON-3 Computer Code
(LWR) fuel rod under normal, steady-state reactor operating conditions and mild transients. Based on prescribed time histories of fuel rod power and coolant inlet conditions, the code calculates the ... one-dimensional formulation brings execution times to a minimum. They are typical in the order of ten seconds on office-class personal computers, which makes the code feasible for probabilistic analyses. The organization...
