"DEMO Double Null architectural study"
31st Symposium on Fusion Technology (SOFT), Dubrovnik, Croatia, 20 - 25 September 2020

DEMO is a key part of the EU fusion roadmap, and the programme reaches the end of the pre-conceptual phase with a gate review in 2020. As part of the work to complete this phase, eight Key Design Integration Issues (KDII’s) have been identified as critical to the programme. Two of these KDII’s identified a requirement for a more detailed archit…

A thorough physics and engineering analysis of alternative divertor configurations is carried out by examining benefits and problems by comparing the baseline single null solution with a Snowflake, an X- and a Super-X divertor. It is observed that alternative configurations can provide margin and resilience against large power fluctuations, but the…

"Integration of service pipes into the lower port for the DEMO Double Null Concept Design Study"
31st Symposium on Fusion Technology (SOFT)

E. Organ S. Ha J. Holt G. Keech J. Keep C. Shaw A. Wilde

A study into the viability of a double null concept for DEMO has been undertaken as part of the work to address Key Design Integration Issues (KDIIs) within the DEMO powerplant.  The objective of this study was to evaluate the feasibility of a double null architecture, featuring split blanket segments to enable a wider range of maintenance options…

"European DEMO first wall shaping and limiters design and analysis status"
14th International Symposium on Fusion Nuclear Technology (ISFNT-14) Budapest,Hungary, 22-27 September 2019

Z. Vizvary W. Arter C. Bachmann T. R. Barrett B. Chuilon P. Cooper M. Firdaouss T. Franke J. Gerardin R. Gowland M. Kovari F. Maviglia L. M. Richiusa E. V. Rosa Adame C. Vorpahl A. Wilde Y. Xue

The anticipated heat flux limit of the European DEMO first wall is ~1MW/m2. During transient and off normal events, the heat load deposited on the wall would be much larger than that the steady state heat load and exceed the first wall limit, therefore the breeding blanket first wall needs to be protected in such events. This involves de…
