摘要	Transport modeling of a proposed ITER steady-state scenario based on DIII-D high poloidalbeta (beta(p)) discharges finds that ITB formation can occur with either sufficient rotation or a negative central shear q-profile. The high beta(p) scenario is characterized by a large bootstrap current fraction (80%) which reduces the demands on the external current drive, and a large radius internal transport barrier which is associated with excellent normalized confinement. Modeling predictions of the electron transport in the high beta(p) scenario improve as q(95) approaches levels similar to typical existing models of ITER steady-state and the ion transport is turbulence dominated. Typical temperature and density profiles from the non-inductive high beta(p) scenario on DIII-D are scaled according to 0D modeling predictions of the requirements for achieving a Q = 5 steady-state fusion gain in ITER with 'day one' heating and current drive capabilities. Then, TGLF turbulence modeling is carried out under systematic variations of the toroidal rotation and the core q-profile. A high bootstrap fraction, high beta(p) scenario is found to be near an ITB formation threshold, and either strong negative central magnetic shear or rotation in a high bootstrap fraction are found to successfully provide the turbulence suppression required to achieve Q = 5.
