  1. Source Control Phases I-II:Main findings Phase I - 2000-2002 Chemical Hazards • Facility: drinking water and sewage treatment utility in Apatity, Murmansk region, Russian Federation • Risk Assessment Methodology at Hazardous Industrial Facilities (chemical hazards - chlorine) was developed incorporating ISO 14001 approach • Analysis of risks was performed; recommendations made to reduce facility risks Phase II – 2003-2004 Radiation Hazards • Facility: Fuel Research Department (FRD) of State Scientific Centre of Russian Federation “Scientific and Research Institute of Atomic Reactors” (SSC RF NIIAR) • Risk Assessment Methodology at Hazardous Industrial Facilities developed in Phase I of the Project was applied to the radiation hazard facility incorporating ISO 14001 approach; • Priorities for corrective actions were identified; • Recommendations to enhance the safety of the facility were made based upon the analysis of risks

  2. Source Control Project, Phase III • Objectives: • Verify and finalize the developed Risk Assessment Methodology at radiation and chemical hazardous facilities of the Industrial North of Russia • Carry out the risk assessment and develop recommendations to reduce the risk at selected hazardous facilities • Sites: • FSUE “CS Zvezdochka" • The facility activities include nuclear submarine decommissioning, repair and upgrade of vessels and nuclear submarines • FSUE "Atomflot“ The facility maintains and repairs nuclear powered vessels • The project is implementing by: • IBRAE RAN, FSUE "Atomflot" andFSUE “CS Zvezdochka"supporting by US Department of Energy • Duration: • 2005 – 2008

  3. The Complex includes: • Part of special quay 40 m long where a portal crane is installed; • Building for loading of transport containers with SNF; • Temporary storage facility for transport containers, and; • Site for forming of special train Phase III : FSUE “CS Zvezdochka“ Onshore complex for unloading of the SNF from the decommissioned submarines The technological cycle includes operations on transportation and loading of spent nuclear fuel into transport containers, storage of containers loaded with SNF, loading/unloading works and transportation of containers loaded with SNF, and deactivation operations

  4. Phase III : FSUE “Atomflot“ The facility maintains and repairs nuclear powered vessels as well as repairs reactor equipment, manages solid and liquid radioactive waste. • Totallength of berthage is over 1 km • 3 portal cranes including KONE crane of 100 ton capacity for SNF container unloading • 2 branch lines of local railway over 1 km long • Storage facility for SRW containersof 400 cubic meters • Storage facility for high level SRW of 216 cells • Temporary storage facility for LRW of 200 cubic meters

  5. PMP FSUE «CS «Zvezdochka» PMP FSUE «Atomflot» Phase III: Project Management Plans • Forming a working team,distribute the functions and responsibilities • Studying of requirements of regulatory and legal documents • Planning and organization of works • Identification of hazards and preliminary risk assessment, selection of the most hazardous scenarios to carry out a detailed quantitative risk assessment • Preparing more detailed data on selected scenarios and quantitative risk assessment • Making conclusions and development of the recommendations on risk management and reduction of risks in the future

  6. The following initial events was studied: Phase III: Preliminary Risk Assessment Goal: selection of the most hazardous scenarios tocarry out a detailed quantitative risk assessment • Loss of offsite power; • Fire or eventual overheating; • Fall equipment component • Fall equipment component containing SFA • External impacts (earthquake forces, fall aircraft plane)

  7. Scenarios 1 3 2 Phase III: Quantitative Risk Assessment / Risk Matrix FSUE “CS Zvezdochka“

  8. Phase III: Quantitative Risk Assessment / Risk Matrix FSUE “Atomflot“

  9. Phase III: Risk Assessment Methodology at HIF and Facilities Handling Radioactive/Nuclear Materials • The work is implemented in accordance with the Risk Assessment Methodology developed in the framework of earlier Phase I and Phase II of the Source Control Project (2000-2004). • The Document includes detailed description of the main stages of risk assessment, the procedures of hazards identification and assessment and the method of corrective actions ranking in accordance with their priorities and terms of execution. Phases III • The changes was made in order to provide better understanding • List of federal and departmental legal documents regulating facility activities during SNF unloading is added to the Document

  10. Phase III: Main Findings • The risk assessment was performed atSNF unloading coastal facilities of FSUE “CS Zvezdochka" and FSUE “Atomflot" • The executed risk analysis shows that the facilities have acceptable level of safety. • The conclusions were made and the recommendations on risk management and reduction of risks in the futureweredeveloped • Work results demonstrateadaptability of developed methodology for radiation and chemically hazardous industrial facilities
