This is a re-opening of the vacancy. Candidates who already applied do not need to re-submit an application.

Organizational Setting

The objective of the Department of Nuclear Energy (NE) is to foster the efficient and safe use of nuclear power by supporting interested Member States in: improving the performance of nuclear power plants, the nuclear fuel cycle, and the management of nuclear wastes; catalysing innovation in nuclear power and fuel cycle technologies; developing indigenous capabilities around the world for national energy planning; deploying new nuclear power plants; preserving and disseminating nuclear information and knowledge; and advancing science and industry through improved operation of research reactors.

The department has a dynamic, participative and interactive operating environment with inputs received from the Board of Governors, the General Conference, policy and decision-makers, and technical counterparts in Member States and the international development community.

The Division of Nuclear Power comprises the Nuclear Power Engineering Section, the Nuclear Power Technology Development Section, the Nuclear Infrastructure Development Section and the INPRO (International Project on Innovative Nuclear Reactors and Fuel Cycles) Section. The Division provides core engineering, technological, human resource development and management support to interested Member States in the field of nuclear power.

The Nuclear Power Technology Development Section assists Member States in developing safe, environmentally benign, economically viable, proliferation resistant and sustainable innovative solutions for all civil reactor technologies, including water-cooled reactors, gas-cooled reactors, fast neutron systems (both critical and sub-critical) as well as small and medium-sized reactors. The section fosters international collaboration on technology development for reactor plants and for non-electric uses of nuclear power by facilitating coordinated research projects, technical meetings, and training courses. The section also maintains the Advanced Reactor Information System (ARIS) and Thermophysical Properties of Nuclear Materials (THERPRO) databases.

Main Purpose

Within the Nuclear Power Technology Development Section led by the Section Head, and as a member of the project Technology Development for Advanced Water Cooled Reactor, the Nuclear Engineer (HWR) formulates, develops, organizes and implements IAEA’s activities on: technology development,, simulation and modelling methods, and design aspects for advanced water cooled reactors with the focus on heavy water reactors (HWRs), as well as cross-cutting technical issues for all large advanced water cooled reactor designs.


The Nuclear Engineer (HWR) is an expert in water cooled reactor technologies with the extensive knowledge of HWRs. He/she is a facilitator, encouraging cooperative design and development through communication with members of the Technical Working Group on Advanced Technologies for HWRs and other similar groups and international organizations working on cross-cutting technical issues for all large advanced water-cooled reactors.

Functions / Key Results Expected

As scientific secretary, plans, coordinates and reports on the activities of the Department of Nuclear Energy’s Technical Working Group on Advanced Technologies for HWRs.

Maintain current knowledge of the status of advanced large water cooled reactor technology programmes focused on HWR technology and related development programmes.

Coordinate and encourage cooperative research in advanced large water cooled reactor technologies focused on HWR technologies and cross-cutting issues.

Contribute to the planning and implementation of joint activities between the HWR and LWR (light water reactor) Technical Working Groups.
