The 2D neutron emissivity is calculated using the minimum Fisher regularization method. 1D profiles suitable for transport analysis are then obtained by subsequent poloidal integration. Tritium transport in the plasma core approaches the neoclassical level in some cases. For the set of plasmas analysed and within the uncertainty, tritium particle confinement follows the ITER IPB98(y,2) particle scaling confinement.
