SUMMARY:Proposal of International Mega-science Project on Fusion Volum
 etric Neutron Source (FVNS)\, SPECIAL SEMINAR\, Zhibin CHEN\, Frontier
  Development of Science
DESCRIPTION:Main challenges for fusion energy development are the stea
 dy-state operation and tritium self-sufficiency (tritium breeding). Ho
 wever\, in current fusion development strategy in the world\, main pro
 grams were proposed aiming to solve the steady-state operation and tri
 tium self-sufficiency challenges simultaneously in one reactor\, such 
 as EU-DEMO\, CFETR and so on. It will be in a predicament due to that 
 the tritium self-sufficiency requires steady state operation of fusion
  reactor for high availability\, but which in turn relies on high reli
 ability of breeding blanket for tritium self-sufficiency. Thus\, we be
 lieve that the reliability of breeding blanket\, including the related
  materials\, should be developed and tested in advance without conside
 ring the tritium self-sufficiency.
\n 
\nGas dynamic trap is expected 
 to be the most promising compact volumetric fusion neutron source conc
 ept\, mainly because of its own features and meanwhile benefited from 
 the magnificent advancement of fusion technologies\, such as supercond
 ucting magnet\, plasma auxiliary heating\, neutral beam injection\, pl
 asma diagnostics and control\, etc. It can reach steady-state operatio
 n and high neutron flux with relative low fusion power (~3 MW) and low
  tritium consumption (<200g per year)\, so that it is not necessary to
  have tritium breeding but provide a real multiple-effect coupling fus
 ion nuclear environment\, with relatively large test volume for fusion
  material test and components test.
\n 
\nBased on these\, an internat
 ional mega-science project on fusion volumetric neutron source (FVNS) 
 based on GDT was jointly initiated by Institute of Nuclear Energy Safe
 ty Technology (INEST)\, Chinese Academy of Sciences and Budker Institu
 te of Nuclear Physics (BINP)\, Russia Academy of Sciences. FVNS will b
 e used for fusion nuclear technology and fusion-fission hybrid reactor
  development\, and also for other early fusion applications such as ne
 utron radiography\, medical isotope production\, neutron therapy\, etc
 . It is planned to be designed in 5 years\, constructed in 5 years and
  operated in 20 years in both DD and DT operation modes.
\n 
\nAn inte
 rnational preparatory committee of FVNS has been established together 
 with world distinguished scientists from University of Wisconsin-Madis
 on\, National Science Center Kharkiv Institute of Physics and Technolo
 gy\, and Uppsala University\, etc. The 1st preparatory committee meeti
 ng was held on 21 November 2018 at INEST to form the development strat
 egy and collaboration plans in different development stage of FVNS. A 
 wider international collaboration is also being built under the framew
 ork of the international preparatory committee.
