General Comments
1. Country and type of organization (operator, regulator, service supplier,
government ministry, waste management organization, other)
2. Overview of the strategy for spent fuel management in your country
3. Considering the steps of the back-end (i.e. storage, transportation, reprocessing
& recycling, and/or disposal):
I. What are the main issues associated to the interfaces between these activities?
Please, provide examples of how these issues are being addressed or will be
addressed by your organization (or country) in the future
II. Identify potential impacts of changing strategy, political decisions, economic
decisions, etc
III. If spent fuel storage period is envisaged to be extended, have your country/facility
addressed the issue of license renewal and the potential impacts of changing
conditions and/or regulations?
IV. If so, what are the issues and concerns?
V. Impact of waste acceptance criteria
4. What mechanisms are used to facilitate communication between reactor
operators, associated vendors, regulators, waste management organization, …?
5. Mechanisms for information management (records retention)
6. Mechanisms for knowledge management 2Thank you! Anselmo F. Miranda Fuel and Safety Analysis Advisory TechnicalDirectorate miranda@eletronuclear.gov.br +55 21 2588-7780
