As part of the joint Dragon/THTR graphite irradiation programme, experimental techniques have been evolved for measuring the irradiation creep of graphite at high temperatures. The principle of the method is to retrain the irradiation induced dimensional changes to produce a stressed assembly which gives rise to irradiation creep phenomena in the different components. Its main advantage is that little irradiation space is required compared to techniques involving the use of direct loads. It is shown that in the parts of a restrained assembly under irradiation, a stress is built up which after a certain neutron dose reaches an equilibrium value. Measurement of this equilibrium stress enables one to calculate the radiation creep constant of the graphite investigated. Some general results are shown for speciments strained in tension. (auth)
