SOLPS5 Simulations of Type I ELMing H-mode at JET

B. Gulejová, R.A. Pitts, D. Coster, X. Bonnin, M. Beurskens, S. Jachmich, A. Kallenbach and JET EFDA contributors 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 Ip, ~8MJ stored energy plasmas with ELMs approaching 1MJ, modelled 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, 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.
