  1. CRAFT Meeting 28 September- 2 october 2015 Overview of the Mediterranean project INT/9/176"Strengthening Cradle-to-Grave Control of Radioactive Sources in the Mediterranean Region” Soumia ZEROUAL Abderrahim BOUIH

  2. CRAFT Meeting 28 September- 2 october 2015 Introduction (1/2) • The INT9176 project was set up for and within Mediterranean countries and it was expanded to other countries outside the Mediterranean region. • The objective of the project is a Cradle to grave control over the sources to ovoid any accidents or other occurrences involving radioactive sources.

  3. CRAFT Meeting 28 September- 2 october 2015 Introduction (2/2) • One of the principal task of this TC Project INT9176 is to establish and improve the capacity in the region for safety demonstration namely development of SCs and supporting SAs for predisposal management of DSRS in accordance with the IAEA safety standards.

  4. CRAFT Meeting 28 September- 2 october 2015 Model of safety case • Selected countries have adopted and followed a model in drafting their safety cases respecting the specificities of each country, with the assistance of the IAEA • Tunisia • Mauritius • Bosnia and Herzegovina (BOH) • Ghana • Morocco • The choice of the five countries is dictated by the representativeness of the various steps that can have a radioactive waste management facility: • Safety case for the planning phase and construction (Tunisia and Mauritius) • Safety case to authorize a plant already built to house the radioactive waste management (Ghana and BOH) • Safety case for a radioactive source management activity in an already permitted and licensed facility (Morocco)

  5. CRAFT Meeting 28 September- 2 october 2015 Model of Safety case • The assessment of safety is based on the evaluation in normal conditions and in accidental situations. • In an accidental situation all possible scenarios that have a possibility to occur are considered depending on weather, hydrological, seismic and demographic conditions. • The safety assessment was done using the SAFRAN software developed by the IAEA. • The draft of safety case was developed in accordance with GSG-3 and national regulation of each country.

  6. CRAFT Meeting 28 September- 2 october 2015 Model of safety case • The principle chapters of the model are: • Introduction • Context of the Safety Case • Strategy for Safety • General Description of the Facilities, Activities and the DSRS • Safety Assessment • Iteration and Optimization • Identification of Safety Measures • Limits, Controls and Conditions • Integration of Safety Arguments • Interacting Processes

  7. CRAFT Meeting 28 September- 2 october 2015 Safety assessment • The assessment endpoints for the radiological impact are radiation doses and risks to workers and public from normal operations and from accidents, both internally and externally initiated. • The endpoints for the site and engineering assessment include a demonstration of good engineering practice, suitability of the site, facility robustness and compatibility between all materials, engineered components and the site elements. • The endpoint for operations is an assurance that safe working conditions are in place in respect of operations including both radiological and non-radiological hazards.

  8. CRAFT Meeting 28 September- 2 october 2015 Safety case of Tunisia • The CNRP regulates the use of all activities involving ionizing radiation and the management of DSRS. • DSRS which constitute most of the radioactive wastes present in the country, are normally stored at the site of generation under CNRP supervision. • A storage facility of radioactive waste of low and medium level of activity in the CNSTN is under construction. The developed SC and SA will be as a support for the licensing process (storage facility at National level).

  9. CRAFT Meeting 28 September- 2 october 2015 Safety case of Tunisia • The SC for the CNSTN is basically a comprehensive radiation risk assessment that confirms the acceptability of the earmarked site for the project and specifies the safety requirements for the design, construction and operation of the centralized storage facility. • The Safety Case covers the following activities: • Receiving, identification, characterization and handling of DSRS; • Temporary storage of the DSRS at CNSTN; • Conditioning of the DSRS for long term storage; • Handling and placement into final storage.

  10. CRAFT Meeting 28 September- 2 october 2015 Safety case of Tunisia • The following specific aspects was addressed in this safety case: • Demonstration of the safety of the proposed Waste Management Facility. • Demonstration of the safety of various proposed RWM activities that will be performed by CNSTN. These activities include receiving and characterization of the DSRS, temporary storage, conditioning and longer term storage. • Optimization of the respective waste management activities. • Management systems implemented in support and to ensure the safety of the respective waste management activities. • Definition of Limits, Controls and Conditions that will be applicable to the respective activities. • Input to and further development of existing monitoring and programmes and activity procedures.

  11. CRAFT Meeting 28 September- 2 october 2015 Safety case of Mauritius • The Radiation Protection Authority (RPA) as the national regulatory body to regulate the use of all activities involving ionizing radiation • Due to lack of adequate infrastructures, many of these radioactive sources are not being stored in optimum safety and security conditions. To improve this situation, the Government of Mauritius is planning to have a Centralized Radiological Source Storage Facility (CRSSF) for the long term storage of all DSRS that cannot be returned abroad to their suppliers or manufacturers.

  12. CRAFT Meeting 28 September- 2 october 2015 Safety case of Mauritius • The Government of Mauritius is planning the construction of a Centralised Radiological Source Storage Facility (CRSSF). • The storage facility will be operated and managed by the Services Unit of the Radiation Protection Authority (RPASU). There is currently no other competent national organization to assume this responsibility. • This Safety Case will be used as a basis for decision making for the siting and the preliminary design of the CRSSF. • This SC will be used as supporting document to request the required clearances from the relevant authorities for the development of CRSSF project.

  13. CRAFT Meeting 28 September- 2 october 2015 Safety case of Mauritius • This SC covers the following activities: • Receipt and inspection of DSRS; • Emplacement of the DSRS in the storage areas; • Periodic inspections of the DSRS; • Maintenance of the CRSSF. • The activities specifically excluded from this SC are: • Conditioning of the DSRS at the user’s facility for long term storage; • Transportation of the DSRS to the CRSSF; • Processing or manipulation of the DSRS or their housing, containers or packaging

  14. CRAFT Meeting 28 September- 2 october 2015 Safety case of Bosnia and Herzegovina (BOH) • The State Regulatory Agency for Radiation and Nuclear Safety (SRARNS) is the regulatory body for licensing and exercising regulatory control. • Rakovica Radioactive Waste Storage Facility (RF) is established, since 1998, and has been operated as the centralized radioactive waste storage facility of the Federation of BOH. • The RF is not formally licensed

  15. CRAFT Meeting 28 September- 2 october 2015 Safety case of Bosnia and Herzegovina (BOH) • The operator of the RFhas been theInstitute for Public Health of Federation of BOH (IPH). • The State Regulatory Agency for Radiation and Nuclear Safety (SRARNS) is the responsible authority for licensing and exercising regulatory control over the IPH. • The SRARNS is currently exploring options for a new site with robust buildings that could be used for centralized long term storage of radioactive waste/DSRS. • Awaiting for the construction of the new centralized radioactive waste storage facility, the RF needs safety assessment in order to continue operation.

  16. CRAFT Meeting 28 September- 2 october 2015 Safety case of Bosnia and Herzegovina (BOH) The following specific aspects are addressed in this SC: • Demonstration of the safety of RF. • Demonstration of the safety of various radioactive waste management activities performed by the IPH (receiving and characterization of the DSRS, segregation of waste, storage and limited processing of RLR and smoke detectors). • Optimization of the respective waste management activities. • Identification of measures to upgrade the facility for conditioning of the DSRS. • Management systems implemented to ensure the safety and quality of the respective waste management activities. • Definition of limits, controls and conditions that will be applicable to the facilities and the respective activities. • Input to the improvement of existing radiation protection programmes and activity procedures.

  17. CRAFT Meeting 28 September- 2 october 2015 Safety case of Ghana • The Radiation Protection Board (RPB) is the competent authority in Ghana for authorizing and inspection of radioactive material and practices. • The National Radioactive Waste Management center (NRWMC) is responsible for the management of radioactive waste at national level in Ghana. Centralized storage facility • NRWMC is responsible for the establishment of a Centralized Waste Processing Facility (CWPF) and a Centralized Storage Facility.

  18. CRAFT Meeting 28 September- 2 october 2015 Safety case of Ghana • The NRWMC was authorized to manage and store the radioactive waste by the RPB base on safety assessment and arguments which are not fully in compliance with international standard. • A decision has been taken to develop a SC in line with current international standards, and request an updated license on the basis of this SC. • The SC provides a description of how the safety aspects of the storage facility, the site, design, operation and the managerial controls satisfy safety requirements

  19. CRAFT Meeting 28 September- 2 october 2015 Safety case of Morocco • A licensing system for nuclear facilities is described by the decree number 2-94-666 of 1994. • After consultation with the National Commission of Nuclear Safety, the Ministry of Energy, Mines, Environment and Water gives authorizations for: • Construction of nuclear installation • Discharging of liquid and gas effluents to the environment • Commissioning • Operation • Decommissioning • All these authorizations are delivered base on safety analysis report.

  20. CRAFT Meeting 28 September- 2 october 2015 Safety case of Morocco • The assessment of safety for the management of DSRS was based on the calculation of the dose rate of the pre-cemented drum containing the source with its working shield, without taking in consideration all the steps involved in the management: loading, unloading, transport, transfer to the storage building and accidental scenario to assess the dose that an operator could receive. RWM facility Storage facility

  21. CRAFT Meeting 28 September- 2 october 2015 Safety case of Morocco • As the Moroccan facilities are already established and activities relating to the management of DSRS are already taking place, the purpose of the assessment was both retrospective (todetermine whether the existing situation, e.g., facility lifecycle stage, is acceptable from a safety and security point of view) and proactive (to determine whether corrective action to upgrade safety and/or security measures is necessary).

  22. CRAFT Meeting 28 September- 2 october 2015 Safety case of Morocco The safety cases including safety assessments has cover the following activities: • Collection and transport of DSRS to the centralized radioactive waste management facility; • Receiving, identification, characterization and handling of DSRS when it arrives at the centralized facility; • Temporary storage of the DSRS at the centralized facility; • Dismantling of DSRS • Conditioning of the DSRS • Handling and placement into final storage
