As a "Nuclear Safety Analyst Severe Accident", you are jointly responsible for determining the strategy on how Severe Accidents can be detected in MYRRHA without giving rise to serious discharges to the environment. In order to determine this strategy and to demonstrate its effectiveness, models must be developed that are capable of realistically or conservatively predicting the behaviour of the installation in highly degraded Severe Accident conditions.
At present, the analysis of Severe Accidents is primarily carried out using models in SIMMER (a coupled thermohydraulic/neutronic code) and using simplified conservative analytical calculations.
The development of reliable models to study these severe accidents requires an extremely in-depth understanding of thermohydraulics and reactor physics.
In many cases, it concerns models and solutions that are innovative and scientific in nature and the results of which can be published in the relevant professional literature.
