First and second core pressure vessel steel samples have been tested after irradiation. The shift in N.D.T. -30 ft-lb. for samples being irradiated for an integrated dose of 5.5 x 1018 , 1.2 x 1019, 9.5 x 1019, 2.2 x 1020 n.v.t. is resp. +30, +50, +140 and +200*C. Considering the sample positions, it can be concluded that the BR3 vessel is still safe. I f, in the future, a drastic change would be observed, annealing of the vessel could be considered.
