Netherlands: PhD (or Post-doc) Gas-Cooled Fast Reactor

Font size: Decrease font Enlarge font

The Gas-cooled Fast Reactor is a promising reactor design within the Generation-IV initiative. It produces heat at a high temperature and is able to recycle all actinides, thereby reducing the lifetime of the nuclear waste considerably and enhancing the utilisation of uranium. This project focuses on the European GFR design with a high power output and on the demonstrator reactor named ALLEGRO. The project will be carried out in close cooperation with other partners within the European Union FP7 project GoFastR. This research aims at investigating the core physics and thermal hydraulic evaluation of the core and assessing the uncertainties in the design due to the input parameters and nuclear data. Besides standard methods available in codes like APOLLO and ERANOS, use will be made of a non-linear adjoint sensitivity methodology developed at TU Delft. Furthermore, a safety assessment of the GFR and of the ALLEGRO reactor designs will be made using CATHARE and other code systems.


The position can be filled with either a post-doc for a period of 30 months or a PhD student for 48 months. The candidate should have a background in (applied) physics, and should be fluent in English (written and spoken). The candidate will be based in Delft. Delft University of Technology is a bilingual organisation.

Conditions of employment

The successful candidate will be employed full-time by TU Delft for a fixed period of four years within which he or she is expected to write a dissertation leading to a doctoral degree (PhD thesis). The starting salary for a PhD is €2042 gross per month increasing to a maximum of €2612 gross per month in the fourth year. TU Delft offers an attractive benefits package, including a flexible work week, free high-speed Internet access from home, and the option of assembling a customised compensation and benefits package. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. Delft University of Technology strives to increase the number of women in higher academic positions; women are therefore especially encouraged to apply. For more information about this position, please contact Dr. Ir. J.L. Kloosterman, phone: +31 (0)15-2781191, e-mail: Please apply before 15 May 2010 by using our on-line application form, which can be found at Only applications submitted via the on-line application form will be evaluated. When applying for this position, make sure to mention vacancy number TNWRRR10-012. Foreign students are advised to mention their GRE (physics) and TOEFL scores in the application letter.

Delft University of Technology

Delft University of Technology (TU Delft) is a multifaceted institution offering education and carrying out research in the technical sciences at an internationally recognised level. Education, research and design are strongly oriented towards applicability. TU Delft develops technologies for future generations, focusing on sustainability, safety and economic vitality. At TU Delft you will work in an environment where technical sciences and society converge. TU Delft comprises eight faculties, unique laboratories, research institutes and schools.


Applied Sciences

The Department of Radiation, Radionuclides and Reactors ( is located in the Reactor Institute Delft (RID). The department’s common focus is nuclear radiation and reactions. Although its areas of interest are varied, ranging from materials, sensors and instrumentation to energy, sustainable production and health, all the department’s research is related to radiation in some way. In experimental research, extensive use is made of the research facilities of the Reactor Institute Delft as well as of large, international research facilities. The Physics of Nuclear Reactors (PNR) section focuses on the design and analysis of innovative nuclear reactor systems aimed at improved efficiency and a high degree of safety, flexibility and user-friendliness, combined with a reduction in radioactive waste production. The main emphasis of the research is on Generation-IV reactors with a view toward increasing the sustainability of nuclear energy.??
