In the frame of the French law for the researches about waste management, different dynamic scenarios have been studied [1]. These scenarios are considering the French case and start from the present situation, which consists in a single stage of Plutonium recycling in PWRs. The scenarios described in this paper take into account two main options: Continuation of nuclear energy or phase out option.

ABSTRACTThe final disposal of nuclear waste is at the interface between the technologies of the nuclear fuel cycle that produce the waste and the natural hydrologic and geochemical cycles of geologic repositories. Despite this broad interdisciplinary scope, nuclear waste management, as practiced, remains “balkanized” among the relevant disciplines. The individual subdisciplines continue to work in relative isolation from one another: materials science dealing with the immobilization of nuclear waste; engineering science dealing with the design, construction and operation of the repository; geoscience dealing with the long-term behavior of host rocks and the hydrology; health science dealing with the effects of radiation; social sciences dealing with the issues of trust, risk and ethics. Understanding how these very different disciplines interact is fundamental to creating and managing a nuclear waste organization. Based on a comprehensive review of the scholarly and scientific literature of waste management, we have analyzed the evolution and structure of research in nuclear waste management between 1979 and 2017. Focusing on materials science, we show that some research themes have been isolated from the most central themes of nuclear waste management. Moreover, we observed a relative decline of the fundamental research in materials science. This decline was evidenced by a drop in the number of articles published in the proceedings of the MRS symposia “Scientific Basis for Nuclear Waste Management” since 2000. We argue for the need to more precisely and inclusively define the field of nuclear waste management.

It is a great pleasure for me to deliver the keynote address this morning, opening the 18th International Symposium on the Scientific Basis for Nuclear Waste Management. On behalf of the Atomic Energy Commission of Japan, I would like to welcome all of you, particularly those who have travelled across the ocean to attend this symposium.

Radioactive waste arises in large quantities only as a consequence of the civil and military applications of nuclear energy. The problems connected with its management and eventual disposal are not, therefore, problems that would have suggested themselves as topics for research but for the existence of large-scale reactor operations. Interest in nuclear waste management has therefore both a social and a scientific origin. This is not to say, however, that the researches that are necessary in order safely and responsibly to handle nuclear radioactive waste arisings do not entrain questions of considerable scientific interest in their own right. In particular, the need to find secure disposal routes and sites lead us into geological and marine researches that have a high interest in their own academic right. There is, similarly, very considerable scientific interest in establishing and understanding the interlinked pathways through which nuclear waste, buried or otherwise disposed of, might work its way back into the food chain.

In 2011, the Swedish Nuclear Fuel and Waste Management Company (SKB) applied for a permit to construct a disposal facility. The Swedish government is expected to make a decision in 2020. Three surveys have been conducted to investigate how informed the Swedish Members of Parliament (MP) and the citizens are in these issues. The first study with the MPs was done in 2013, the second in 2016 and the one with the citizens was conducted in the winter of 2018/2019. The results show that most MPs and half of the citizens were aware of the ongoing permission process. Rather surprisingly, there were more politicians and citizens who knew about the suggestions to use copper canisters, than knew the suggested location. In general, nuclear waste was seen as an important issue by all respondents. A majority of the MPs and the citizens believed that Sweden can dispose the waste in a safe manner. Among the citizens, the trust in politicians’ decisions on where and how to build a final repository were low and more trust was put into scientists and experts. Half of the citizens wanted to see a phase out of nuclear power, over half of the MPs meant that the repository should be designed so that the withdrawal of nuclear waste can be done.

Producing nuclear energy inherently produces high active nuclear waste (HAW), which has to be disposed of properly and safely. Disposal of HAW represents an eternal burden of nuclear power – even after the German nuclear phase-out in 2022. This intergenerational challenge is a challenge for many more countries than just Germany. Up to date, in the whole world, there is not one operational disposal facility for HAW. The author deals with the constitutional requirements for the German Site Selection Process and the evaluation criteria derived from the constitution. Based on an international legal comparison, he finally develops recommendations concerning a further legal development of this process. The legal comparison particularly emphasizes Canada, Switzerland and Finland.

System Project

As one of the candidates in the Generation IV reactors program., the molten salt reactor (MSR) has the properties of online refueling and fuel salt reprocessing, MSR is especially attractive for the Thorium fuel cycle, which is very ideal for nuclear non-proliferation, radiotoxicity and nuclear energy sustainability. Therefore, the “Thorium-based Molten Salt Reactor (TMSR) nuclear system” project has been proposed as one of the “Strategic Priority Research Program” of Chinese Academy of Science (CAS). In this paper, we mainly investigated the influence on the breeding ratio and waste radiotoxicity with different reprocessing schemes. By considering the key parameters mentioned above, the aim is to choose an efficient reprocessing scheme for TMSR to reach self-breeding with Th/U fuel cycle and minimize the radioactive waste production of the molten salt.

I can honestly say that I am very proud to get this opportunity to open this symposium and provide a few opening remarks on nuclear energy and nuclear waste management. I was once a nuclear chemist myself. Moreover, the Royal Swedish Academy of Engineering Sciences, IVA, has since her start in 1919 been concerned with all aspects of energy questions and energy politics but particularly in recent decades with the nuclear energy issues.

The Impact

ABSTRACTThe potential value of Partitioning/Transmutation (P/T) strategies for high-level nuclear waste management has been investigated (one would be tempted so say “periodically”) since 1970. The basic physics phenomena are well understood, and scenarios for the fuel cycle can be imagined. However, the criteria to judge the impact of P/T are matter for discussion (and controversy). Moreover the relation to disciplines other than reactor physics can be significant (e.g. innovative fuels and Actinide chemistry).A number of key issues are revisited here and will be discussed in some detail.
