KTH: Royal Institute of Technology, Sweden


Kungliga Tekniska Högskolan (KTH) is the largest technical university in Sweden and has about 12000 undergraduate students, 1440 graduate students, and 2800 employees. KTH is organised into six schools, which together contain about 40 different departments. The Division of Reactor Physics has 14 employees and belongs to the Department of Physics which is a part of the School of Engineering Science.

KTH has been conducting research on transmutation of nuclear waste since 1991. The division of reactor physics is or has been coordinating European P&T projects in the 4th framework programme (IABAT), the 5th (CONFIRM) and the 6th (RedImpact). To our competence belongs design and safety calculation for accelerator driven systems and Genration IV reactors dedicated to minor actinide burning, reactivity monitoring methods in sub-critical systems, thermo-chemical simulations of transmutation fuel fabrication processes, and simulation of radiation damage in transition metal alloys using multi-scale methods. Since 2003, six Ph. D. theses directly focused on transmutation of nuclear waste has been successfully defended by students from our division. Within the international master’s programme in Nuclear Energy Engineering of KTH, the division is giving courses in Reactor physics, Transmutation of nuclear waste, Generation IV reactors, Chemistry and physics of nuclear fuels and Radiation damage.

In the framework of "FREYA", KTH will participate in measurements of reactivity in sub-critical configurations of the VENUS-F facility. KTH will also be responsible for training & education activities within work package 5, relying on experience in teaching reactor physics laboratory exercises in thermal spectrum reactors.

Key persons in the project:

Professor Janne Wallenius, obtained his Ph. D. degree in quantum chemistry from Uppsala University in 1996. Since 1997 he has been performing research on transmutation of nuclear waste at the reactor physics division at KTH. His activities include design and safety simulations of accelerator driven systems, Generation IV reactors and multi-scale modelling of radiation damage in Fe-Cr alloys. He coordinated the fifth framework programmne CONFIRM, concerning development of uranium free nitride fuels for transmutation. He has authored or co-authored 40 publications in peer reviewed journals and five Ph. D. students have completed their thesis under his supervision. He has developed courses in Transmutation of nuclear waste and Generation IV reactors. Since 2007, Janne Wallenius is the head of the reactor physics division and the centre for nuclear energy technology (CEKERT) at KTH.

Mr. Carl Berglöf, is Ph. D. student at the division of reactor physics. In 2007 he presented his licentiate thesis on reactivity monitoring methods in the sub-critical facility YALINA in Sosny, Belarus. He has extensive experience from experimental campaigns in YALINA and YALINA-BOOSTER, as well as from developing methods for analyzing reactivity measurements. Mr Berglöf will defend his Ph. D. thesis on the topic in May 2010.
