Abstract
The objectives, the experimental research programme and the first
results of the FRAME project are described in the paper. Altogether 26
different materials were irradiated in a single irradiation capsule and
the Master Curve based T0 shifts were measured for
each material. In addition four materials were studied in the programme
extension. Altogether approximately 700 fracture toughness specimens
were tested in the project. The aim of FRAME was to start systematic
development of Master Curve based embrittlement monitoring. Fracture
toughness test is clearly superior to Charpy-V test but for historical
reasons large databases, on which embrittlement trend curves can be
based, exist only for the Charpy-V test. The test data validation
procedure used in the project is described with some detail. No bias was
noticed between the three main testing partners in the created data.
First estimate for a model, which describes the dependence of
embrittlement on the copper, phosphorus and nickel contents of the
material, is given.
