  • Sep 2014
Before their uses in industrial nuclear power plants (NPP), materials and fuel have to follow a long qualification process with different stages of screening, selection, qualification, optimization, processing, lifetime assessment and safety tests. These studies are most of the time associated with a complex multi-physical modelling of the material...

On figure 1, we can also see 6 water channels distributed around the reflector, where displacement systems will receive specific devices, a priori dedicated for fuel irradiations. Many calculations were performed to estimate neutron flux levels, by TRIPOLI 4.7 associated with JEFF-3.1 nuclear data library and considering a start-up fuel configuration (U 3 Si 2 fuel and 70MW of core thermal power).In this configuration, the highest fast flux in the core is 3. .s ...

This thesis deals with the real-time control of singing voice synthesis by a graphic tablet, based on the digital musical instrument Cantor Digitalis. The relevance of the graphic tablet for the intonation control is first considered, showing that the tablet provides a more precise pitch control than real voice in experimental conditions. To extend...

Poor performance of a control loop is usually caused by poor controller tuning, presence of disturbances, control loop interactions and/or loop nonlinearities. The presence of nonlinearities in control loops is one of the main reasons for poor performance of a linear controller designed based on linear control theory. In a control loop, nonlinearit...

It is hard to observe yoghurt making manually in long time period and in a large scale production. Thus, it is crucial to develop a controlling instrumentation that can give a continous yoghurt making process temperature and pH without any human existence as observer. The aim of this project was to build and develop a yoghurt making machine using d...

Conventional photolithography normally utilizes a photomask for patterning light onto a chemical resist film. Therefore, the accuracy of microfabrication is highly dependent on the accuracy of the photo-masks. Fabrication of hard masks involves the use of expensive laser pattern generators and other sophisticated machines using very high-precision...

All materials and equipment used in space systems and satellites need to undergo thermal tests to check their performance and anticipate possible failures or abnormalities. The CubeSats also undergo these thermal tests in order to qualify their operation, when they are exposed to a vacuum environment and temperature variation imposed by the space e...

Conceptual design of test devices for the JHR tailored to the needs of the nuclear fusion community
Article
  • Oct 2017
  • FUSION ENG DES
Since 2015, within the scope of the Jules Horowitz Reactor (JHR) project a collaborative effort between CCFE in the UK and CEA in France has been undertaken to investigate concepts of test devices for the JHR suitable for the needs of fusion researchers. It is hoped that in having optimized experimental devices designed will facilitate use of the JHR by the fusion community. The project chose to focus on more instrumented test devices as it was felt that post-irradiation examination (PIE) type experiments at conventional temperatures could be undertaken with limited modifications to existing test devices. After internal exploration of the options, three potential test devices were identified; i) testing of ceramic functional materials; ii) testing at cryogenic temperatures; and iii) testing of thermo-mechanical fatigue. Each of these devices has been conceptually designed, demonstrating feasibility. This paper describes each of the conceptual designs at their current level of maturity. Future collaborative work planned between the two parties will aim to develop these devices further.
