Status of the first SINQ irradiation experiment, STIP-I

The irradiation program at SINQ was initiated in 1996 in collaboration with Commissariat a l'Energie Atomique Centre d'Etudes de Saclay (CEA), Forschu ngszentrum Julich (FZJ), Japanese Atomic Energy Research Institute (JAERI), Los Alamos National Laboratory (LANL) and Oak Ridge National Laboratory (O RNL). The first irradiation experiment (STIP-I) was carried out from July 1 998 to December 1999 in SINQ target MARK-II, which received total charge of 6.8 A h of protons with a peak fluence of 3.2 x 10(25) p/m(2). In this exp eriment more than 1500 samples of different types of Fe-, Al-, Zr-, Ni-, Ti -, W-, Mo-based alloys and their weld materials were irradiated. At the sam e time, 101 dosimetry detectors of Al, An, Co, Cu, Fe, Ni, Nb and Ti were p laced close to the samples in order to analyse the spallation spectrum at d ifferent positions. In addition, there were 11 rods from austenitic and mar tensitic steels and Zircaloy-2, 3 tubes of Zircaloy-2 and 7 lead (Pb) fille d tubes of 9Cr-1Mo irradiated for different testing purposes, which would a lso be available for the post-irradiation examination (PIE). The irradiated samples have been retrieved and will be tested soon by different laborator ies. The main results of the PIE should be available in 2001. (C) 2001 Else vier Science B.V.
