World Bank, IAEA partner to fund nuclear energy
The World Bank and the International Atomic Energy Agency signed an agreement last week to cooperate on the construction and financing of advanced nuclear projects in developing countries, marking the first partnership since the bank ended its ban on funding for nuclear energy projects.

The selection of the operating temperatures for a sodium-cooled fast reactor (SFR) always involves a trade-off between the plant performance and cost. In this work, the general trends with an increase of the core outlet temperature were calculated for the Advanced Burner Reactor (ABR). First, the benefits of higher temperatures in terms of the higher plant efficiency were calculated for several power conversion systems. To characterize the disadvantages of higher temperatures, the safety margins were investigated for the design conditions, normal operational transients, and beyond-design-basis accidents. The limiting criteria were identified for both oxide and metal fuel core designs. In addition, the effect of the higher temperatures on the structural thicknesses was estimated. A preliminary cost analysis incorporating both benefits and cost penalties of higher temperatures showed the economical benefit potential of higher temperatures, provided that the safety requirements are satisfied by the design and/or material selection.
