This paper aims to contribute both to the ongoing process of scrape-off layer code-experiment and code-code benchmarking. Results are presented from SOLPS5 simulations of two high power JET H-modes with similar magnetic configuration, concentrating in the first case on the ELM-free phase of high 1p, similar to 8 MJ stored energy plasmas with ELMs approaching 1 MJ, modeled for the first time with this code package. A second pulse, with lower stored energy and smaller ELMs, originally considered in detail by Kallenbach with the EDGE2D-NIMBUS code package [Kallenbach et al., Plasma Phys. Control. Fus. 46 (2004) 431], has been modeled as a benchmarking exercise featuring a high level of complexity including carbon impurities and the full ELM cycle. Good agreement is found between the code results. The SOLPS5 results are used to analyse the energy balance during the ELM cycle. In both H-mode discharges, a strong inward particle pinch in the pedestal region is found to be necessary to match measured upstream profiles. (C) 2009 Elsevier B.V. All rights reserved.
