[en] The presentation elaborates on the NE 2012 priorities; the NE Action Plan Activities with NS; on the support for advanced newcomers; on the stable fuel cycle services; on the starting points for INPRO planning; and on the GIF Interactions.
[en] Objectives of PR&PP Working Group: • Facilitate introduction of safeguards and security features into the design process at the earliest possible stage of concept development; • Assure that conclusions of PR&PP assessments are an aid to informing decisions by policy makers in areas involving safety, economics, sustainability, and related institutional and legal issues.
[en] Twelve action points for Member States and IAEA: • Safety assessments; • Peer reviews; • Emergency Preparedness and Response; • National Regulatory Bodies; • Operating Organisations; • Safety Standards; • International Legal Framework; • Embarking countries; • Capacity building; • Protecting people and the environment from ionising radiation • Communications and information dissemination; • Research and Development.
[en] Overview of the VHTR fuels and fuel cycle project; the VHTR materials project; the VHTR Hydrogen Production Project; the VHTR Computational Methods, Validation and Benchmarking Project; and of the VHTR System Arrangement Outlook.
[en] Summary: • Two promising SCWR concepts have been worked out and published; pressure tube concept still under development. • Technology development ongoing. • A fuel qualification test is being designed and licensed. • Successful collaboration between GIF and INPRO is demonstrated in joint meetings and conferences.
[en] Purposes of Integrated Safety Assessment Methodology (ISAM) and its purpose: • Commensurate with design maturity, yields a complete and detailed understanding of relevant risk and safety issues. • Within a given concept or design: – guides the design process based on a detailed understanding of risk and safety; – helps identify areas for additional research and data collection. • Promotes understanding of differences between concepts and designs based on risk and safety issues; • Allow evaluation of a concept or design relative to various safety metrics or “figures of merit”; • Support licensing and regulatory processes.
[en] PROSA - Ultimate Goal: • Make the assessment of Proliferation Resistance simpler, less time consuming. • Make findings of the assessment more understandable (by identifying strengths and weaknesses). • Use only the depth of analysis necessary to address the user’s needs, e.g. for the simplest, preliminary assessment: – At the Facility level - safeguardability analysis; – At the State level - legal obligations including full implementation of the additional protocol; – At the NES level - acquisition path analysis. • Improve volume 5 of the INPRO manual on Assessment of Proliferation Resistance.
[en] Conclusion: • GIF Cost Estimating Methodology is available for use by all GIF projects. • Training for users is available at varying levels of detail. • The EMWG continues to monitor Methodology applications. • Small scale activities on additional GEN IV related case studies.
[en] Design Extension Condition (DEC): • Severe Accident: [SA] – Important due to the characteristics of SFR. – Prevention of the occurrences & Mitigation of the consequences shall be required. – Consequences of severe reactivity insertion, which might occur in the course of the CDA, shall be accommodated. • Built-in measures against the CDA: – On the designs of fuel and assemblies, reactor core, core support structure, shutdown system, coolant system and/or containment system, – By effectively utilization of passive mechanisms.
