N2 - The SNS accelerator has been operating for over one year at the mega-Watt power level with beam availability of 90%. This paper reviews the operational experience and discusses how the experience has compared to design stage expectations. The super-conducting RF linac has encountered some operational surprises, yet proved to be remarkably flexible. The spread of SRF cavity gradients is higher than expected, but operation is robust to different cavity gradient setups. The storage ring used to provide short pulse (ms) beam delivery on target is operated close to design expectations. Importantly, beam loss has not been a power limitation to date.
