La communauté du LLFP Meydan. Les parents sont au coeur de la communauté scolaire et s’associent aux divers acteurs de l’établissement, personnels enseignants, vie scolaire, administration et direction pour promouvoir l’excellence, le développement académique, l’esprit d’appartenance et le bien- être des élèves.

Only seven fission products have long half-lives, and these are much longer than 30 years, in the range of 200,000 to 16 million years. These are known as long-lived fission products (LLFP). Three have relatively high yields of about 6%, while the rest appear at much lower yields.

2017年10月24日 · This study comprises the results of “Research and development of an innovative transmutation system of LLFP by fast reactors”, entrusted to the Tokyo Institute of Technology by the Ministry of ...

2023年1月30日 · The LLFPs assembly is comprised of 91 pins, each of which contains one LLFP element; the number of pins containing each LLFP element is balanced to optimize their transmutation.

The spallation process burns the LLFP target while producing many secondary neutrons that can be further used for transmuting the LLFPs. A preliminary analysis suggests that a 1000 MeV beam with a 10 mA current can transmute around 1kg/year of technetium-99 due to nuclear reactions without accounting for spallation reactions.

2019年12月16日 · The feasibility of the LLFP transmutation target was clarified through experiments on material properties and fabrication of the LLFP target, YH2 and YD2 moderators.

在这项研究中，我们提出了一种先进核能系统 (anes) 的新概念，用于在不分离同位素的情况下有效地嬗变 llfp。 ANES 包括强光中子源 (PNS) 和亚临界反应堆，由铅铋 (Pb-Bi) 层、铍 (Be) 层、燃料、LLFP 和屏蔽组件组成。

2020年7月1日 · The purpose of this research was to improve the transmutation efficiency and to construct a fast reactor LLFP transmutation system that combines not only one fast reactor, but also multiple fast reactors to secure SR of one or more in the entire system. In this study, the elements of LLFP were used without isotopic separation of the six nuclides.

llfp的嬗变依赖于热中子俘获反应，在快堆包裹层中建立热中子区即可实现llfp(如99-tc和129-i}的嬗变。 由此可见，通过闭式快堆核燃料循环(包括分离一嬗变)，不仅可以充分利用铀资源，实现铀资源利用的最优化，还能大大减少高放废物的体积及其放射性毒性 ...
