CEA to sponsor NACE corrosion courses in London. Three corrosion education and training courses developed by the National Association of Corrosion Engineers (NACE) are being offered by the Corrosion Engineering Association (CEA) during the Winter 1989/1990 in the London, Heathrow area. The Basic Corrosion Couse will be offered twice, 26 November‐1 December 1989 and 18–23 February 1990. The Protective Coatings and Linings Course also is scheduled for 26 November to 1 December 1989, and the NACE course covering Corrosion Control in Oil and Gas Production will be held 18–23 February 1990. The week‐long courses will be conducted at the Holiday Inn Sough/Windsor and fees are UK £525 for CEA, NACE, and Institution of Corrosion Science and Technology (ICorrST) members, or UK £575 for nonmembers.

The chemical reprocessing of irradiated nuclear fuel involves the handling of highly radioactive and often hot or highly corrosive solutions, usually containing nitric acid. This demands plant constructed to a high standard of integrity from suitably resistant materials. The difficulty of carrying out maintenance or repair of active plant which fails due to corrosion means that an adequate corrosion allowance, based on reliable data, must be included at the design stage. The data on which to base the allowance are gathered from small‐and rig‐scale laboratory experiments where coupons or vessels, tubing, etc fabricated from the candidate material(s) are exposed to a simulated process environment. This is backed up whenever possible by corrosion data accruing from the operation of existing plants and by exposure of specimens to the actual plant environment followed by metallographic examination. The constructional materials most commonly used in reprocessing plants are austenitic grades of stainless steel along with smaller quantities of refractory metals like titanium. This, unsurprisingly, is in line with current practices in the nitric acid manufacturing industry.

The largest event in Europe devoted exclusively to anti‐corrosion technology is to be staged at the Cunard International Hotel, London, on November 16–18.

ACEL — Tay Bridge cathodic protection. Aberdeen Corrosion Engineers Ltd in conjunction with R B R (Scotland) Limited, have been awarded a major contract for structural repairs and installation of cathodic protection to supporting columns of the River Tay A92 Road Bridge at Dundee. Work commenced during July 1989, and comprises installation of expanded titanium mesh using both sprayed and poured mortar overlays.

The parameters for Quality Control of both the anti‐corrosion coating and, where required, concrete weight coaling, are reviewed for six major pipelines in which the authors have been directly involved. The importance of field joint anti‐corrosion coatings are discussed, particularly for concrete weight coated pipelines. The differing environment of each project is identified and includes “in‐service” temperature, water depth, mode of pipe lay, together with cathodic protection considerations. The importance of quality control is traced from initial design study to coating and includes practical aspects of on‐site quality assurance. Material selection, application, inspection, safety aspects and economics are discussed.
