8 TOPICS 1. TRITIUM In this topic the tritium fuel cycle development will be considered, not only the status of technology and systems but also aspects relating to power plant requirements such as (start-up) inventory and availability. The presentations will review the international status and identify gaps and requirements for further work. Subjects covered are: Overview of the tritium fuel cycle and conditions for self sufficiency Physics calculations of tritium burn fraction in plasma Tritium Extraction and Processing Technologies: Assessment of state-of-the art, particularly in ITER, and required extrapolation to DEMO Tritium Transport, Permeation and Control and requirements for DEMO Availability of tritium in the impact of ITER Topic Chair: M. Abdou, Co-chair : S. Willms 2. DEMO PHYSICS GAPS AND IMPACT ON ENGINEERING DESIGN Considerable uncertainty surrounds the definition of the operating plasma for DEMO machines, as a consequence engineering design must accommodate a range of requirements. In this topic there will be a review of present knowledge and its limitations with respect to DEMO scaling and prediction, together with the prospects for more benign plasma operation such as ELM-free. The impact of these uncertainties on engineering design margins will be analysed. The physics basis for a stellarator based DEMO will be presented. Subjects covered include: H mode core plasma confinement Steady state scenarios for a DEMO tokamak Power exhaust Operational margins and impact on design Physics basis and prospect for a stellarator DEMO Topic Chair: W. Biel, Co-chair: H. Zohm 3. DEMO HEATING AND CURRENT DRIVE PHYSICS AND TECHNOLOGY HCD systems fulfil multiple roles in a DEMO from pre-pulse wall conditioning, through plasma burn and ramp down to post-pulse detritiation in addition to acting as actuators for MHD and profile control and non-inductive current drive. Determining the optimum mix of HCD systems must also account for their impact on the tritium breeding ratio and the extension of the nuclear island. In this Topic the requirements arising from the various applications of HCD will be discussed. An international status review of each system will then be presented that will include existing plans for development, exhausting and required test facilities. One of the major issues for HCD on DEMO is reliability and the system reviews will address the present state of knowledge and consider methods for improving and demonstrating reliability. Subjects covered: Overview of plasma physics HCD requirements EC Systems International Status and Prospects NB Systems International Status and Prospects IC Systems International Status and Prospects LH International Systems Status and Prospects Topic Chair: E. Surrey, Co-chair: I. Jenkins 4. SPECIAL TOPICS A quantitative operating programme for FNSF and its impact on requirements, R&D needs, etc. Updates on national roadmap plans, i.e. focusing on significant progress or changes since the last workshop. KIT R&D in Support of EU DEMO
