    A comprehensive review of the status of the reconstitution technique, as applied to reactor pressure vessel steel, is given. The reconstruction techniques in use at this moment on different small-size specimen geometries are highlighted, and the reconstitution methodology is evaluated. The advantages and limitations of reconstituted specimens are discussed, in relation to preparation and material conditions and in view of the test techniques to be used. For plant life management issues, the importance of finding an indexing parameter independent of the reconstitution process will be indicated.
