2020/21
A European nuclear and energy engineer looking for a job in his/her actual field of specialization will probably find it in the area of nuclear fuel cycle, waste and decommissioning. In the EU, these topics gather most of the nuclear-related planned activities in the short and medium term. The process of fabricating fuel (front end of the fuel cycle) includes different steps from uranium ore exploration and mining to fabrication of fuel assemblies. While uranium mining activities are limited in the EU, abundant uranium resources are available worldwide. European companies rank among the world's major producers of nuclear fuel. Major investments have been made in the past in conversion and enrichment capabilities and fuel fabrication, and the focus in the coming years will be on modernising them in order to maintain EU technological leadership. The back-end of the fuel cycle will need increasing levels of attention: it is estimated that more than 50 of the 129 reactors currently in operation in the EU are to be shut down by 2025/2030. Based on the latest information provided by Member States, the largest 20 European nuclear operators estimated that nuclear decommissioning, radioactive waste management and disposal will be “the main question” until 2050 in the EU. This course is tailored to enable the student to get knowledge and skills in all the above topics. Aspects dealing with peculiar Italian nuclear legislation and situation will be dealt with. Aspects dealing with nuclear non-proliferation and safeguards – essential activity of the IAEA – will be examined too

The aim of the Course is to meet the needs of students at graduate level, to acquire knowledge and training in nuclear fuel cycle, waste and decommissioning field. The course also aims to provide the necessary basic tools for those who will become professionals in the waste management field, and the safeguards implementation too. It is designed to provide both theoretical and practical training in the multidisciplinary scientific and/or technical bases of national and international recommendations and standards in such fields. At the end of the course the students should be able to address all the front-end and back-end technologies in the nuclear field: “outside the nuclear reactor, it is all my business”.

Lectures and practical part in times of COVID emergency The instructor guarantees, following the Politecnico's guidelines, that it will be possible to attend all theoretical lessons remotely, and they will be recorded and available on the course website. If the emergency situation will permit it, lessons could be given in mixed mode: in presence (for those students able to be in the classroom), with the possibility to attend remotely, and recorded. The same applies to the practical part, but here students will be divided into small groups in order to carry on the practical part in mixed mode anyway.

The theoretical lectures are completed by a practical part, dealing with the use of the environmental impact evaluation code GENII-FRAMES. After learning the use of the code, the students will be divided into groups of maximum three people, and will be guided during the elaboration of a Case Report (CR), concerning a practical case (disposal of radioactive waste, environmental remediation, etc.). The report will be evaluated and contributes to the final grade (see grading criteria). A visit to a radiation protection lab and learning of in-field use of instrumentation is part of the program.

Lecture notes on each topic will be provided online by the instructors. The following texts are recommended: Decommissioning of Nuclear Power Plants, Research Reactors and Other Nuclear Fuel Cycle Facilities, Specific Safety Guide, IAEA Safety Standards Series No. SSG-47 (available online). Cacuci, Dan Gabriel (Ed.), Handbook of Nuclear Engineering, Vol. 5: Fuel Cycles, Decommissioning, Waste Disposal and Safeguards, Wiley, 2010 (available online).

Modalità di esame: Prova orale obbligatoria; Prova scritta a risposta aperta o chiusa tramite PC con l'utilizzo della piattaforma di ateneo Exam integrata con strumenti di proctoring (Respondus);
Exam: written test, followed, after test grading by the instructors, by an oral discussion of the test results and of CR The exam is aimed at checking the student's knowledge about the topics listed in the official program of the course and his ability to apply the theory and the relative methods to answer questions dealing with Nuclear Fuel Cycle, Waste and Decommissioning. The exam consists of a written test with three open-ended questions on the topics contained in the course program. It aims to verify the level of knowledge and understanding of the covered topics. In particular, it aims to verify the skills specified in the "Expected learning outcomes" part. Time to answer: 90 minutes. Each question gets a grade going from 0 to 10. Each part is considered "pass" when the grade is equal or higher to 5. Summing up the three grades (if they are “pass”) the provisional final evaluation (a grade from 18 to 30) is obtained, which will be completed with the evaluation of the Report CR (see Course Structure), to get the final grade. The CR report may be evaluated as follows (in brackets the effect on the provisional final evaluation): Insufficient (must be edited until sufficient), sufficient (+0), good (+1). The exam is considered "pass" when the final grade is equal or higher to 18/30. During the written exam, it is not allowed to keep and consult books and notebooks. The results of the written test are communicated on the portal, loading in the Materials section appropriate files with the grades), together with a date in which the students can participate to the oral discussion. The oral discussion deals with a collective review of the test results, followed by the possibility for each student of viewing his personal written elaborates, and ask questions, followed by a brief discussion of the CR report.
Exam: Compulsory oral exam; Computer-based written test with open-ended questions or multiple-choice questions using the Exam platform and proctoring tools (Respondus);
