Since 1984 government‐funded fast reactor R&D in France, Germany and the UK has been run as a collaborative activity, and since 1988 as a unified programme in support of the design and construction of the advanced European Fast Reactor. This paper describes the international management structure which has been set up, and the means used to control the work. It is written from the point of view of those engaged in the project, and makes no attempt at a formal analysis of the structure.
The main difficulty is that control of funding remains with the three governments. The R&D programme has to be managed so that it meets the needs of each government separately as well as the designers' requirements.
To start with the management structure was excessively bureaucratic, but it has become more flexible and efficient. This has happened as the initial nationalistic suspicions have broken down, and the staff engaged in the work have learnt more about each others' ways of working so that an atmosphere of trust and inter‐dependence has grown up.
(This paper was written before the changes in UK policy on fast reactor development were announced in November 1992.)
