Objective
THE OVERALL AIM OF THE PROPOSED WORK IS TO ADVANCE THE DEVELOPMENT AND VALIDATION OF MATHEMATICAL MODELS DESIGNED TO PREDICT THE LONG TERM CORROSION OF CARBON STEEL WASTE CONTAINERS IN GEOLOGICAL DISPOSAL ENVIRONMENTS THROUGH:
(A) TESTING THE VALIDITY OF MATHEMATICAL MODELS DEVELOPED AT HARWELL, TO PREDICT THE FORM OF CORROSION AND ITS RATE OF PROPAGATION, BY COMPARING THE PREDICTIONS WITH THE RESULTS AND OBSERVATION FROM THE MOL 'IN SITU' EXPERIMENTS.
(B) APPLICATION OF THE HARWELL MODELS TO AID IN THE INTERPRETATION OF THE RESULTS OBTAINED FROM THE MOL 'IN SITU' TESTS.
1. SCOPE OF THE PROGRAMME
THE OVERALL STRATEGY FOR THE PROGRAMME IS TO APPLY A METHODOLOGY, WHICH WAS BEEN DEVELOPED IN THE UK, TO PREDICT THE FORM OF CORROSION EXPECTED IN THE MOL 'IN SITU' TEST PROGRAMME. SUBSEQUENT TO THIS, THE MATHEMATICAL MODELS OF UNIFORM AND LOCALISED CORROSION WILL BE APPLIED TO PREDICT THE MAGNITUDE OF THE ATTACK. COMPARISON OF THESE PREDICTIONS WITH ACTUAL RESULTS FOR THE MOL 'IN SITU' TESTS WILL FORM A BASIS FOR TESTING THE VALIDITY OF THE METHODOLOGY AND ITS ASSOCIATED MODELS. THIS MECHANISTIC APPROACH WILL ALSO BE USED TO AID IN THE INTERPRETATION OF THE RESULTS FROM THE MOL 'IN SITU' TESTS.
2. PREDICTING THE FORM OF CORROSION
CORROSION ATTACK MAY EITHER BE UNIFORM OR LOCALISED (NB NEGLECTING MECHANO-CHEMICAL PROCESSES SUCH AS STRESS CORROSION CRACKING. THE LATTER MAY BE SUB-DIVIDED INTO PITTING, CREVICE CORROSION, INTERGRANULAR CORROSION, WELD ATTACK, ETC. OF THESE PITTING AND CREVICE CORROSION ARE OF MOST CONCERN WITH CARBON STEEL WASTE CONTAINERS. HOWEVER, A MECHANISTICALLY BASED CASE HAS BEEN DEVELOPED TO SHOW THAT SUCH ATTACK IS ONLY FEASIBLE UNDER AEROBIC CONDITIONS. CONSEQUENTLY, IT IS POSSIBLE TO PREDICT THE MAXIMUM PERIOD DURING WHICH LOCALISED ATTACK MAY OCCUR BY EVALUATING THE RATE OF TRANSPORT OF OXYGEN AND OTHER OXIDISING SPECIMENS TO THE MATHEMATICAL MODEL FOR DOING THIS HAS BEEN DEVELOPED AND WILL BE MODIFIED AND APPLIED TO THE MOL TEST CONDITIONS.
3. PREDICTING THE LEVEL OF CORROSION
ONCE THE TIME PERIOD FOR LOCALISED ATTACK HAS BEEN ESTABLISHED, THE DEPTHS OF BOTH LOCALISED AND UNIFORM CORROSION CAN BE PREDICTED BY THE MODELS OF THESE PROCESSES, WHICH HAVE BEEN DEVELOPED AT HARWELL.
4. COMPARISON OF THEORETICAL PREDICTIONS WITH EXPERIMENTAL RESULTS
COMPARISON BETWEEN THE EXPERIMENTAL RESULTS AND THE THEORETICAL PREDICTIONS WILL FORM A BASIS FOR ASSESSING THE VALIDITY OF THE MATHEMATICAL MODELS. IT IS ALSO PROBABLE THAT THIS COMPARISON WILL BE USEFUL IN INTERPRETING THE PROCESSES OCCURRING IN THE "IN SITU" EXPERIMENTS.
