Doctoral Student in Nuclear Engineering – Severe Accident Management in Nordic BWRs KTH Royal Institute of Technology in Sweden

This doctoral position at KTH Royal Institute of Technology offers an exciting opportunity to contribute to the advancement of severe accident management strategies in Nordic boiling water reactor (BWR) plants. The project focuses on understanding and mitigating the risks associated with corium melt release from the reactor vessel, particularly the fragmentation of melt in deep water pools and the formation of coolable corium debris beds. A key concern is the potential for energetic interactions between hot corium and water coolant, which could compromise containment integrity. The research aims to develop innovative methods for addressing the most influential sources of uncertainty in severe accident progression, utilizing the ROAAM+ framework for comprehensive risk assessment.

As a doctoral student, you will be part of international collaborative projects and work under the supervision of Professor Pavel Kudinov, with additional contact from Professor Pär Olsson. The position is based in Stockholm, Sweden, at KTH, a leading technical university renowned for its commitment to sustainability, equality, and innovation. The research environment is dynamic and creative, offering excellent working conditions and a range of employee benefits.

Eligibility requirements include a completed second cycle degree (such as a master's) or at least 240 higher education credits, with a minimum of 60 credits at the second-cycle level, or equivalent qualifications. Proficiency in English (equivalent to English B/6) is mandatory. The selection process emphasizes personal qualities such as goal orientation, perseverance, independence, collaboration skills, and the ability to analyze complex issues. Candidates should have knowledge in nuclear power, fluid dynamics, thermohydraulics, severe accident phenomena, and numerical simulations. Security clearance may be required for certain roles.

The position offers full-time employment for up to four years, with a monthly salary according to KTH’s doctoral student salary agreement. Doctoral students may also engage in training and administrative tasks up to 20% of their role. The application process requires submission through KTH's recruitment system, including a CV, application letter, certified copies of diplomas and grades, proof of language proficiency, and representative publications or technical reports. The deadline for applications is January 9, 2026.

Join KTH and contribute to shaping the future of nuclear safety and risk management in a supportive and forward-thinking academic environment.
