EDF Chooz A NPP, France
Background
CHOOZ A STE building will be decommissioned and EDF DPD2 wants to simulate waste streams and check waste evacuation planning from decommissioning activities. This building is very specific and has a lot of constrains with waste sources spread on 5 levels.
Challenge
- Study the waste stream planed of the water treatment plant decommissioning in Chooz A
- Creation of a simulation model for four different logistic combinations on Complete or partial installation decommissioning and CENTRACO or ANDRA waste route strategy
- Ensure that the estimated waste stream meets the planning requirements as assessed by the nuclear operator
- Design of specific paths accounting for the constraints of the surroundings over 5 levels
Our proposal
- Identify and to analyze bottlenecks, improving paths considering the technical and logistics constraints
- Propose conclusions for planning recommendations
- Identification of bottlenecks due to:
- too slow measuring devices
- reduced storage capacity close to lifting tools
- a heavy trap door blocking access because it takes too long to be moved
Customer benefits and results
Avoidance of work closure risk Recommendations:
- The initial planning can be fulfilled but specific parameters and conditions need to be reviewed
- Storage capacity within intermediary locations
- Work organisation and human resources
- Adaptation of current trap doors
