ITER Neutronic Challenges for Upper Port 14

Authors: J. P. Klabacha, B. C. Linn, R. E. Feder

Abstract: The future of magnetically confined nuclear fusion facilities is extremely promising, yet there are extensive challenges that still have to be addressed. These challenges range significantly, but one of the more difficult challenges is nuclear shielding and nuclear safety. The challenge of adequately shielding neutrons is especially prevalent at ITER. Throughout the lifetime of ITER there will be large quantities of high energy (14.1-MeV) neutrons generated, with the expected neutron lifetime fluence to be around
