内容記述 |
We propose the models for the systems codes to calculate the bootstrap current fraction, neutral beam-driven current, and synchrotron radiation loss power, considering the plasma profiles with the H-mode pedestals. The scaling formulae of the bootstrap current fraction are developed for the parabolic and H-mode plasma profiles by fitting the data prepared using a magnetohydrodynamic equilibrium calculation code including a detailed model of the bootstrap current. The developed simple model of the neutral beam-driven current is applicable to arbitrary plasma profiles and shapes. We show the geometric approximation of the flux surface averaged magnetic field strength, plasma surface area, and plasma volume to calculate the synchrotron radiation loss power using the CYTRAN module with only the parameters used in the systems codes. The validity of these models is confirmed by comparing the results to those calculated by the detailed models. These models enable the systems codes to consistently consider the plasma profiles with the pedestals in the core plasma power and current balances because the other quantities in the balance equations can be evaluated by calculating the profiles of the quantities and integrating them numerically within computing time acceptable for the systems analysis. |
