The CEC sponsors considerable model development and validation in the area of LWR source term, and naturally wishes to see the results used as widely as possible. It also has a role in fostering collaboration between European teams involved in source term analysis, for which purpose Phebus-FP is acting as a focal point. To further both aims the JRC decided in 1989 to sponsor the development of the best-estimate code ESTER, which is both a software environment and a set of coupled source term modules which, when completed, should offer potentialities not currently available within Europe. This paper describes first the overall architecture of ESTER, then the component parts: the tools and services, the user interface, and the modules which perform the physics and chemistry calculations, emphasising the design choices which have been made. The quality assurance system for the whole system is also reviewed. Contributions from the model developers both underway and expected are then surveyed in the context of the overall development of ESTER, and the planning of the creation and extension of ESTER is given. The paper closes with some plans for sharing ESTER within Europe and for ensuring its maintenance and continued rational development.
