Overview of the SNS target system testing and initial beam operation experience

Helium behavior in ferritic/martensitic steels irradiated in spallation target

“…In both cases, the structural materials suffer from a high level of displacement damage and a high helium production rate. In order to investigate the behavior of these materials in such severe irradiation conditions, various irradiation experiments in spallation conditions have been conducted in the past [1][2][3]. Spallation environment enables one to induce a high displacement damage in a relatively short time, comparable to high flux research reactors [4,5].…”

SNS October 2008 status

“…Commissioning and initial operating experience up to 300 kW have been previously reported [1,2]. For the first run cycle in FY2008 of approximately 2000 h 100% availability was achieved.…”

Neutron performance analysis for ESS target proposal

“…Liquid metal targets have been one of the most accepted options in high power neutron sources (JSNS [14] and SNS [15]) and this concept was the main design option for the European neutron source in 2003 [16]. The MCNPX model is based on ESS-2003 design and it includes three layers of steel (3 mm thick each), a helium gap (2 mm) and a light water channel (3 mm).…”
