Learning Outcome

The aim of the course is to introduce the students to nuclear fusion technology and its research fields. At the end of the course the students are able to understand how the fusion components are designed and manufactured. They are able to remember advanced engineering technologies, which can have application to several other engineering fields and can be useful in the case they will be working in top / innovative engineering fields. The students are also able to apprehend the potentials and the engineering problems of this technology as solution to the future energy demand.

Preconditions

The lecture is offered among others for:
Students in the 5th semester of mechanical engineering, physics, technical physics, technical mathematics and computer science, chemistry, chemistry Engineering.
Prerequisite is the Knowledge of the fundamentals of Physics (Mechanics, Thermodynamics Electromagnetics)

Learning and Teaching Methods

The module consists of lectures and some exercises. In the lectures, the fundamentals of Nuclear Fusion Technology are presented and discussed via a teaching presentation and Power Point slides. The lecture notes are available in moodle, so that the students can make their own notes. Thus they learn to apprehend the potentials and the engineering problems of this technology as solution to the future energy demand.
During the exercises some practical computational examples are shown. Hence students learn for example to understand how the fusion components are designed and manufactured.

Module Exam

Description of exams and course work

The course will introduce the fundamentals of nuclear fusion technology and nuclear fusion reactor engineering. After introducing the main nuclear fusion reactions and the physical backgrounds, it will describe the operating principles of existing fusion devices and those under construction with focus on the Tokamak machines. It will also introduce the concepts of future thermonuclear reactors.

An important part of the course is the description of advanced technologies that in several cases are also used in other high-tech engineering fields such as:
- Superconducting Magnets
- Cryotechnology
- Plasma Technologies
- High heat flux component technologies
- High power Radiofrequency and Microwave heating
- Neutral Beam Injectors
- Breeding balnkets

The exam is only in written form (written exam) and lasts 90 minutes. Auxiliary tool that is allowed is only a pocket computer. By answering comprehension questions and a couple of computational tasks, students demonstrate that they have learned the working principles of nuclear fusion devices and the related advanced technologies and are able to apprehend the potentials and the engineering problems of this technology as solution to the future energy demand.

Current exam dates

Currently TUMonline lists the following exam dates. In addition to the general information above please refer to the current information given during the course.
