Examination Of A Ferritic Martensitic Steel Following Irradiation And High Temperature Water Corrosion

Nuclear energy currently contributes approximately 10 % of the worldwide energy mix.1 Nuclear energy generation is a form of low-carbon electricity, typically run as base-load, which alongside renewables can help nations toward climate change goals. Nuclear fission thermal reactors make up the majority of the reactors operating today. Nuclear fusion on the other hand is a promising alternative which produces less radioactive waste and does not have a reliance on the finite source of uranium fuel. Eurofer-97, a reduced activation ferritic-martensitic (RAFM) steel, will be used as a structural material for fusion reactors. The earliest literature reference to RAFM steels originated from 1994 by Abe et al.2 One option for the European demonstration fusion reactor (DEMO) is to use a water-cooled lead-lithium (PbLi) breeder blanket (WCLL BB) design for heat extraction. Breeder blankets will be used to generate a source of tritium, for the fusion reaction with deuterium.

This paper focuses on the characterization of an advanced steel which has been developed for use as a structural material within future nuclear fusion reactors, including in irradiated water coolant-facing locations. In the paper an experimental plan is described which would allow both the corrosion and stress corrosion cracking susceptibility of irradiated Eurofer-97 to be studied. Also included are early results from characterization of self-ion irradiated (using Fe ions) Eurofer-97 following high temperature corrosion experiments using electron microscopy techniques. Field emission gun scanning electron microscopy (FEG SEM) images of the surfaces of unirradiated Eurofer-97 are compared to conventional unirradiated stainless steel types following a high temperature corrosion experiment. In a different, longer, high temperature corrosion experiment using ion-irradiated Eurofer-97, a focused ion beam scanning electron microscope (FIB SEM) was used to prepare lamella for observation by high magnification transmission electron microscopy (TEM) and elemental analysis.

Uncontrolled growth of microorganisms in the oil field production systems have a major negative impact on the productivity and asset integrity in oil and gas industry. Sulphate-reducing bacteria (SRB) have been found as the most troublesome group of microorganisms among all organisms involved in MIC of carbon steel and other metals used in the oil industry (Abdullah et al 2014). The formation of SRB biofilm on steel surface can affect the kinetics of anodic and cathodic reactions, leading to an acceleration of steel corrosion (Beech and Sunner, 2004: Zuo,2007). In addition to that, SRB contributes to hydrogen sulfide-driven reservoir souring, increased suspended solids, reservoir plugging, etc., in oil field sites.

Martensitic stainless steels for OCTG materials are widely used in sweet and mild sour conditions. Environmentally-assisted cracking (EAC) is a major corrosion-related issue when using stainless steels as OCTG materials. The EAC in specific oil/gas well conditions with sour environments is defined as sulfide stress cracking (SSC) and stress corrosion cracking (SCC). The SSC is a type of cracking caused by hydrogen embrittlement, which is attributed to a cathodic reaction under acidic conditions, while SCC is associated with an anodic reaction. SSC testing for martensitic stainless steels for OCTG material is often carried out at or near ambient temperature under conditions simulating condensed water, and SCC tests are conducted at higher temperatures under conditions simulating formation water and/or the brine availability test.

The power plant is a natural gas-fired, combined cycle plant with three combustion turbines and a single steam turbine. A large stainless steel surface condenser is used to condense steam off of the turbine, and provide high purity steam condensate return to the boiler system. The steam condenser was put into service approximately 15 years ago. This plant takes makeup water for its open recirculating cooling tower water system from a river location that is inland from an ocean coastal area.
