  9. Present activities • Collect existing data, prepare TDR

  10. Present activities • Collect existing data, prepare TDR Severe cracking of the tungsten due to the thermal gradients. Nelson et al. IWSMT-10, JNM, in press.

  11. Present activities • Start experiments on reference tungsten and W-alloys Tungsten alloy: IT180 in helium with 5% oxygen for 2.5 hours. S. Iyengar, E. Malm, Lund Technical University

  12. Short term (2012-13) plan • Investigations on reference tungsten material Characterization of as-received materials Density, Metallurgy, Hardness Mechanical testing at ESS relevant temperatures Tensile, Fatigue, Bend Microstructural analyses TEM: as-received, after testing SEM: fracture behaviour Erosion experiments at KIT( tbd) Oxidation experiments at LTU (tbd)

  13. Short term (2012-13) plan • Investigations on irradiated tungsten material Mechanical testing and Microstructural analyses of STIP-II (@JAEA) and STIP-V (@PSI) samples Tensile, Hardness, Metallurgy, TEM, SEM, gamma-measurements etc.

  14. Overview of materials irradiated in STIP PIE has been partially done.

  15. Short term (2012-13) plan • Investigations on irradiated tungsten material Mechanical testing and Microstructural analyses of STIP-II (@JAEA) and STIP-V (@PSI) samples Tensile, Hardness, Metallurgy, TEM, SEM, gamma-measurements etc. • Investigations on irradiated structural materials Fatigue testing on irradiated SS 316LN samples

  16. Long term (2014-) plan • Irradiate W samples for ESS, CSNS, etc Irradiate W samples in the next SINQ target Irradiation: 2013-2014, PIE: 2016 - W samples considered: R1: 10 W bullets with Ta, Zy-2, SS cladding, HIP’ed R2: 10 W bullets with Ta, Zy-2, SS cladding, caned R3: 1 W rod with Zy-2 cladding, canned, with 2 TCs R4: Bend, Tensile, TEM samplesin 2 surface conditions, in He R5: Bend, Tensile, TEM samples in 2 surface conditions, in He-5%H
