Abstract
An offset nonlinear scaling is developed for the ELMy H-mode by analys ing the ITER II-mode database 1TERH.DB2. The offset part of the stored energy is determined by the MHD stability of ELM, and the incremental confinement time of a nonlinear function of heating power is determin ed by the gyro-Bohm-like transport of the core plasma. This scaling pr edicts a lower confinement time for ITER than that predicted by genera l power-law scaling.
