Nuclear Energy Engineering at KTH

The master’s programme in Nuclear Energy Engineering serves the nuclear engineering-related industry worldwide in its growing need for competent nuclear engineers and researchers. Nuclear engineering is an increasing sector in Europe, as there is a need to maintain and upgrade the existing nuclear power plants. At the same time, there is renewed interest and support from the public and policymakers for nuclear power. Also, new nuclear power technologies and innovations currently being developed promise to deliver clean, reliable and affordable energy that can help reduce greenhouse gas emissions and meet the growing energy demand. The high number of courses and students make this programme one of the largest nuclear engineering programmes in the world with students from all corners of the earth.

The programme consists of several mandatory courses to provide a strong foundation in physics and technology of nuclear reactors and power plants, nuclear power safety, sustainable energy transformation technologies, and radiation protection and dosimetry. You can choose from a great variety of unique courses focusing on different aspects of nuclear power engineering. These include generation IV reactors, small modular reactors, the nuclear fuel cycle, Monte Carlo methods and simulations in nuclear technology, reactor and power plant simulations, thermal-hydraulics, radiation damage in materials, leadership for a safe nuclear power industry, chemistry and physics of nuclear fuels, and numerical methods in nuclear engineering.

Many courses are based on modern teaching methods, such as the flipped classroom approach, and utilise computer-supported interactive assignments and examinations, lecture video recording, and dedicated e-books. Our courses also utilise the APROS simulator – an advanced simulation tool for nuclear reactors and power plants.

All lecturing staff are actively involved in research projects in broad international cooperation. For example, we conduct experiments in severe accident management, heavy metal coolant technology, nuclear fuel materials and thermal hydraulics. Our programme cooperates with several industrial partners in Sweden and abroad. You can carry out your master’s degree projects in companies such as Westinghouse, Studsvik, Vattenfall, OKG, Forsmark, and Vysus Group.

This is a two year programme (120 ECTS credits) given in English. Graduates are awarded the degree of Master of Science. The programme is given mainly at KTH Campus in Stockholm by the School of Engineering Sciences (at KTH).

Courses in the programme

The courses in the programme cover topics such as physics and technology of nuclear reactors and power plants, radiation protection, safety of nuclear power plants, generation IV reactors, small reactors, energy transformations, materials in nuclear engineering, nuclear fuel cycle, simulations of nuclear reactors and power plants.

Future and career

Nuclear power undergoes continuous development as an essential part of carbon-free electricity production. Many reactors are currently under construction worldwide. A new generation of nuclear reactors is being developed and envisioned to answer the growing need for safe, economic and sustainable electricity production.

Students of our master’s programme are highly regarded by industry, authorities and research establishments in Sweden, Europe and worldwide. In Sweden, graduates work at companies such as ABB, Vattenfall Nuclear AB, EON, Westinghouse, Forsmark Kraftgrupp, Ringhals, OKG, Radiation Safety Authority (SSM), Swedish Nuclear Fuel and Waste Management (SKB), Vysus Group, AFRY, Studsvik, Kiwa Inspecta Nuclear AB and other.

Our programme also prepares you for a career in research or continued studies towards a doctoral degree. New positions for doctoral students open in the nuclear engineering field at KTH every year. Our students have also gone to PhD studies at other prominent universities in Europe and USA.

Sustainable development

Graduates from KTH have the knowledge and tools for moving society in a more sustainable direction, as sustainable development is an integral part of all programmes. The three key sustainable development goals addressed by the master's programme in Nuclear Energy Engineering are:

4. Quality Education
Sustainable development goal 7: Affordable and Clean Energy
Sustainable development goal 9. Industry, Innovation and Infrastructure

Quality Education: Education in our programme is subject to continuous transformation and the adoption of effective learning tools. Our courses are taught by active researchers who regularly publish in international journals. Our teachers are highly trained educators.

Affordable and Clean Energy: Our programme directly contributes to developing technology and infrastructure for providing affordable and clean energy. Nuclear power is CO2 free and does not cause climate change associated with the CO2 production of many other means of energy transformation.

Industry, Innovation and Infrastructure: Our programme maintains a strong connection with industry and with innovation within the industry. Some of our courses, such as the SH2610 course (Leadership for Safe Nuclear Power Industry), are taught by invited experts from the industrial sector. Moreover, you can carry out your master’s degree projects in industry.

Faculty and research

The majority of courses are given by the division of Nuclear Engineering. The research conducted at the division aims to improve the performance and safety of existing and future nuclear power plants. Our research focuses on water- and lead-cooled reactors with conventional and advanced fuels.

We apply various computational techniques, including Monte Carlo methods, computational fluid dynamics, density functional theory and system codes for the simulation of transients. The division also operates a high-pressure, 1 MW heated water loop for two-phase flow studies and dry-out testing, and a nuclear fuel manufacturing laboratory, with equipment for manufacturing and characterisation of uranium nitride, silicide and composite fuels.

The following topical areas are currently being pursued:

  • Thermo-mechanic and thermal-hydraulic modelling of LWRs
  • Heat transfer in supercritical water
  • Development and optimisation of advanced Monte Carlo methods
  • Nuclear fuel cycle modelling
  • Design and safety analysis of lead-cooled reactors
  • Science of radiation damage in nuclear steel
  • Advanced nuclear fuel development (mixed oxides, nitrides and silicides)
  • Quantitative validation of computational tools for reactor design and safety analyses
  • Development and application of Risk Oriented Accident Analysis Framework (ROAAM+)
