A proper evaluation of the perturbations of the host rock induced by the excavation and the emplacement of exothermic wastes is essential for the assessment of the long-term safety of high-level radioactive waste disposals in clay formations. The impact of ...
The interactions of trivalent lanthanides and actinides with secondary mineral phases such as calcite is of high importance for the safety assessment of deep geological repositories for high level nuclear waste (HLW). Due to similar ionic radii, calcium-be ...
The LWR-PROTEUS Phase II experimental program was conducted at the Proteus research reactor at the Paul Scherrer Institute (PSI) in the early 2000s. One of its purposes was to gain more insight into the reactivity changes caused by fuel burnup and to devel ...
The architect behind Stockholm Town Hall, Ragnar Östberg (1866-1945), would have turned 150 years the 14th of July this year. Due to the focus of author's PhD research, she spent long time in Stockholm, especially at the Arkitektur –och designcentrum archi ...
At the Paul Scherrer Institut (PSI), a methodology for nuclear data uncertainty propagation in CASMO-5M (C5M) assembly calculations is under development. This paper presents a preliminary application of this methodology to C5M decay heat calculations. Appl ...
This paper studies the possibility of adding an experimental channel into the core of the CROCUS nuclear reactor. Thinking about all the implications of the installation of a channel, different configurations for the insertion of a channel are discussed. T ...
Decomposition into higher species: Intramolecular UIII-mediated homolytic C-O bond cleavage in UIII (alkoxy)siloxy complexes at low temperature and subsequent reduction with KC8 led to unprecedented polymetallic complexes containing siloxy, silanediolate, ...
A room temperature ionic liquid (IL) composed of a quaternary alkylphosphonium (trihexyltetradecylphosphonium, P66614(+)) and tetrakis(pentafluorophenyl) borate anion (TB) was employed within a water| P66614TB (w|P66614TB or w|IL) biphasic system to evalua ...
In this study, we report the results of in situ U(VI) bioreduction experiments at the Integrated Field Research Challenge site in Rifle, Colorado, USA. Columns filled with sediments were deployed into a groundwater well at the site and, after a period of c ...
This chapter summarizes different innovative fuel production techniques using the product streams from an aqueous reprocessing route with a focus on the well-known sol-gel conversion method. There is also reference to additional steps, post sol-gel convers ...
