Design of a complete characterization of bentonite behaviour under high pressure and high temperature

Lyesse Laloui, Simon Salager, Marta Rizzi

Repositories in deep clay geological formations are considered one of the most promising solutions for a sustainable management of High Level radioactive Waste (HLW). The Swiss HLW disposal concept consists in horizontal tunnels excavated at high depth in ...

Thermo-hydro-mechanical simulation of ATLAS in-situ large scale test in Boom Clay

Lyesse Laloui, Bertrand François

Following the need for understanding and quantifying the effect of temperature on the response of a candidate host formation for radioactive waste disposal, finite element modelling of an in-situ thermal experiment has been carried out. Based on a thermo-h ...

An Average-Case Analysis for Rate-Monotonic Multiprocessor Real-time Scheduling

Thomas Rothvoss

We introduce the "First Fit Matching Periods" algorithm for static-priority multiprocessor scheduling of periodic tasks with implicit deadlines and show that it yields asymptotically optimal processor assignments if utilization values are chosen uniformly ...

Analysis of the swelling pressure development in opalinus clay – experimental and modelling aspects

Lyesse Laloui, Hervé Péron, Mathieu Nuth, Simon Salager

In the context of nuclear waste geological storage, deep argillaceous formations are likely to be subjected to complex mechanical, hydraulic, and thermal loads. In particular, the argillaceous material can be firstly dried, and then re-wetted. During the l ...

Radiation protection studies for CERN Linac4/SPL accelerator complex

Egidio Mauro

CERN is presently designing a new chain of accelerators to replace the present Proton Synchrotron (PS) complex: a 160 MeV room-temperature H- linac (Linac4) to replace the present 50 MeV proton linac injector, a 3.5 GeV Superconducting Proton Linac (SPL) t ...

Development of the control assembly pattern and dynamic analysis of the generation IV large gas-cooled fast reactor (GFR)

Gaëtan Girardin

During the past ten years, different independent factors, such as the rapidly increasing worldwide demand in energy, societal concerns about greenhouse gas emissions, and the high and volatile prices for fossil fuels, have contributed to the renewed intere ...

Finite element modeling and experimental study of brittle fracture in tempered martensitic steels for thermonuclear fusion applications

Pablo Federico Mueller

In this work we have studied brittle fracture in high-chromium reduced activation tempered martensitic steels foreseen as structural materials for thermonuclear fusion reactors. Developing the adequate materials that can withstand the severe irradiation co ...

Radiation shielding of a beta-beam rapid cycling synchrotron

Stefania Trovati

In a future beta-beam facility, radioactive ions (namely, 6He and 18Ne) are produced, accelerated, and then stored in a large decay ring, where they eventually produce neutrino beams through beta decay. Radiation protection is of great concern for this fac ...

Management of actinide waste inventories in nuclear phase-out scenarios

Rakesh Chawla, Marco Cometto

The improvement of the "radiological cleanliness" of nuclear energy is a primary goal in the development of advanced reactors and fuel cycles. The multiple recycling of actinides in advanced nuclear systems with fast neutron spectra represents a key option ...

A thermo-hydro-mechanical stress-strain framework for modeling the performance of clay barriers in deep geological repositories for radioactive waste

Lyesse Laloui, Azad Koliji, Bertrand François, Hervé Péron, Mathieu Nuth

Assessing the performance of deep geological repositories for heat-generating radioactive waste requires reliable predictions of the thermo-hydro-mechanical (THM) behaviour of the clay barriers (the buffer material as well as the host rock/clay). This repr ...
