[en] The annual report gives a summary overview of key research and development activities at the Belgian Nuclear Research Centre SCK-CEN in 2010. The report discusses progress and main achievements in the following areas: reactor safety, radioactive waste and clean-up, radiation protection, nuclear research and society, managing nuclear knowledge and fusion research.
[en] Ionising radiation is increasingly being used in medicine. Apart from protecting patients against excessive radiation doses, it is also extremely important to protect medical staff against radiation. In interventional radiology and nuclear medicine, the radiation doses received by physicians and co-workers have to be accurately followed-up. The European project ORAMED provided tools and procedures to monitor and limit the exposure of medical personnel during these applications.
[en] Radiotherapy, radiation protection, nuclear medicine, etc.: there is a growing interest in radio(bio)logy in the health care sector. The number of medical treatments with ionising radiation per year will increase even more. It is therefore increasingly important to closely monitor the possible harmful effects of low radiation doses.
[en] The 4th of March 2010 was not merely the day on which the Belgian government promised to provide official support to MYRRHA. It was also the date of the official inauguration of GUINEVERE. GUINEVERE is the first important experimental step towards realising MYRRHA. With the GUINEVERE project, a whole new class of nuclear systems driven by a particle accelerator is being demonstrated for the first time at SCK-CEN's technical site. This realisation was also a world premiere.
[en] The capital of SCK-CEN is the knowledge of its staff. There is an enormous amount of information circulating within the research centre. A centralised management for all documents is also critical to efficiently manage, share and unlock the expertise. Since 2009, SCK-CEN has been working on a document management system: Alexandria. A first test draft was completed in 2010.
[en] A major Research and Development programme, linked to MYRRHA, aims to further investigate the technological challenges in the design of the MYRRHA reactor between 2010 and 2014. Material qualification is therefore quite a big challenge. The materials specialists at SCK-CEN are looking for an answer to the question of how MYRRHA materials will behave under the demanding conditions inherent in the reactor.
[en] As of 2011, the Plasmatron will occupy a prominent place in the nuclear fusion research of SCK-CEN. With this test facility, a team of scientists will study the interactions between the hot fusion plasma and the plasma wall. These experiments, for which the Plasmatron was specially rebuilt, will offer a lot of scientific input for the materials technologies of ITER and DEMO.
[en] For several decades, scientists from Europe, the United States and Japan have been conducting technological research into nuclear fusion, possibly the energy source of the future. SCK-CEN directly contributes to this research domain. Thus for example, SCK-CEN designs and validates critical components for the irradiation installation IFMIF (International Fusion Material Irradiation Facility). This unit will be used from 2025 onwards to test materials under extreme conditions, similar to those in a fusion reactor.
[en] A number of research reactors in the world, including BR2, are still working on highly enriched proliferation sensitive nuclear fuel. Extremely high-density fuel is required to make possible the switch to low-enriched fuel without loss of effectiveness. In the past few years, SCK-CEN has developed into the global test station for new, low-enriched fuels.
[en] Certain nuclear activities may have an impact on man and the environment. To understand the precise magnitude of the effect, one must first understand the distribution and behaviour of radioactive substances in the environment. This knowledge is also necessary in order to take appropriate measures to reduce radiation exposure. analysing the environmental effects of MYRRHA and of waste disposal facilities are just some of the applications of SCK-CEN biosphere impact studies.
