SPENT FUEL MANAGEMENT

Waste management issues are discussed in more detail in the next chapter. Some countries have already put in place schemes for the disposal of high level waste in geological repositories; others have not yet committed to this approach.

There are additional safety issues associated with the storage of spent MOX fuel since MOX fuel generates more heat than UO2. It may, therefore, be necessary to down-rate dry waste storage. A further point is that storage pools may require additional neutron poison to ensure adequate sub-criticality.
