Fuel element disposal management
Our service helps nuclear power plant operators to carry out the placement of spent fuel elements in transport and storage casks in a technically and economically optimal way. This ensures that the capacity of the wet storage pool is always sufficient for the safe operation of the nuclear power plant.
Functions
Determination of the quantities of fuel elements to be disposed of (short-, medium-, long-term)
Optimization of the disposal of high burn-up U and MOX fuel assemblies
Performance of necessary source term calculations
Determination of the earliest possible time for loading fuel assemblies into the transport and storage casks
compilation of fuel assembly inventories for the cask loadings
Preparation of fuel assembly and cask loading documentation
Assessment of transport and storage casks for high burn-up U and MOX fuel assemblies
Optimization of medium- and long-term disposal planning
Solutions
Concept development (fuel assembly quantities, container requirements, loading dates, ...)
Creation of a fuel element disposal database (power histories, source terms, minimum decay time, ...)
Calculation of the fuel source terms (radiation source strengths, decay power, activity inventory)
Cask loading planning (fuel assembly selection, positioning in the cask according to the ALARA principle, ...)
Execution of the safety-related fuel element verification (fulfilment of the technical acceptance conditions, etc.)
Coordination and compilation of the cask loading documentation (before and after loading)
Recommendations for the further development of the safety-related fuel element verification (calculation of the cask surface areas dose rate)
Utility
Avoidance of capacity bottlenecks in the wet storage basin
Reduction of radiation exposure of personnel
Better utilization of containers with further developed safety-related verification
Cost advantages through customized solutions from a single source
