Abstract

ESTER is a system of codes developed in various laboratories and assembled in host framework for the purpose of calculating LWR severe accident phenomena both in reactors and in small-scale experiments such as Phebus-FP. Codes being incorporated as ESTER modules need to be changed only minimally into their internal working, but are constrained to receive their input data from and supply their output data to an in-core database managed by the framework. This arrangement practically eliminates unwanted crosstalk between modules, and allows all modules access to a set of common facilities. The paper describes the facilities of ESTER, the modules which are offered in the code, and then gives a brief survey of applications, illustrated by sample results. The applications range from reactor sequence calculations (comparison with MELCOR) to Phebus pre-and post-test analyses and calculations of separate effects experiments such as FALCON.
