“…The concept of Accelerator Driven Sub-critical (ADS) system [1][2][3] was proposed in 1990s to transmute the nuclear waste. The strategic objective of ADS is to transmute (burn up) long-lived minor actinide in order to reduce the amount and the radiotoxicity of high radio-toxicity level nuclear waste, and to close the fuel cycle including minor actinides [3].…”

“…In recent years the interest of the nuclear research sector towards liquid lead and lead bismuth eutectic arose due to their selection as working fluids for advanced nuclear applications such as GEN IV, ADS and fusion [1,2]. One example is the development of the accelerator driven system (ADS) MYR-RHA at the Belgian Nuclear Research Centre, SCK•CEN.…”

The effects of temperature and strain rate on the susceptibility of one of the most promising candidate materials for cladding and high temperature components for ADS, Ferritic/Martensitic steel (T91), to liquid metal embrittlement have been investigated in the temperature interval 150-450°C, at strain rates between 1 · 10 À3 s À1 and 1 · 10 À6 s À1 . The effect of the liquid lead bismuth eutectic has been evaluated by comparison between tests in the liquid metal and in Ar with 5% H 2 . Although the untreated T91 material did not undergo liquid metal embrittlement and there was no apparent change in trends of the tensile properties as function of temperature or strain rate due to the liquid metal, the pre-exposed T91, which was exposed to oxygen poor LBE at 450°C for 4000 h and tested at 450°C did show a decrease in total elongation. The total elongation of the untreated T91 specimens in liquid lead bismuth and in H 2 /Ar-gas mixture followed the same dependence on the temperature up to 245°C. At temperatures above 375°C no results are available from testing in controlled gas environment however reference data measured on the same batch of steel in air are used for comparison. Varying the strain rate did not cause any deterioration in the tensile properties of the material in liquid metal compared to those in gas atmosphere. The results are discussed in terms of self-healing mechanism and crack initiation processes.

“…Two types of steel at the highest temperature are considered. For steel 10CD 9-10, the experimental corrosion rate is between 75AE20-110AE20 mm after 3,000 h and for steel Z 10 CD Nb V92 is between 25AE20-40AE20 mm after 2,800 h. With the model of Balbaud-Celerier and Barbier, 6) the predicted corrosion rate is about 239 mm after 3,000 h, which is 2.1 times higher than the maximal experimental results. Figure 7 shows the comparison between the experiment data and our results from the present model for of the pure lead loop.…”

“…[6][7][8] Based on previous experiments, it is found that the corrosion rate in LBE systems depends on many factors such as exposure time, operation temperature, thermal gradient, solid and liquid compositions, flow velocity, etc., and corrosion occurs through several mechanisms such as mass transport, phase transport, erosion-corrosion and cavitation-corrosion. 9) Experimental simulations on all above thermal hydraulic conditions in the laboratory are difficult and expensive, if not impossible.…”

A previous kinetic model on corrosion and precipitation for a non-isothermal LBE pipe/loop system is improved by considering a turbulent core region and a laminar sub-layer, respectively. Exact solutions of the mass transfer equations in both core and boundary regions are obtained. Based on the present model, both of the local corrosion/precipitation rate and bulk concentration can be calculated. The present study shows that the effects of the axial temperature profile on the corrosion/precipitation rate and bulk concentration by applying this model to DELTA loop at the Los Alamos National Laboratory. Correlations for average Sherwood number at the highest isothermal temperature section for both open pipes and close loops are presented. In addition, the present solution can be extended to the more general cases of high Schmidt number mass transfer in the developed turbulent wall-bounded shear flows.
