Spent fuel overview

In this chapter we have attempted to give an overview of current developments concerning waste/water interactions with special emphasis on U02 spent fuel disposal in saturated ground-water conditions and with a specific look at the...

The main methods used for reprocessing of SNF flowsheet were reviewed in a 120 pages report by the Nuclear Energy Agency (NEA 2012). The three main processes are the so-called hydrometallurgy processes (PUREX and UREX), pyromet-allurgy processes and its variations, and the fluoride volatility process (quite like the method used at the uranium conversion facilities discussed in Chapter 1). The report reviewed in detail several of these processes that are deployed in different facilities for various types of spent fuel (NEA 2012). In this section, we shall try to briefly present an overview of the main points and the analytical aspects.

What follows is a brief description of each reactor listed in Table V. Its purpose is to give the reader an overview of the history and the main characteristics of each reactor. It presents general information before discussing details related to the spent fuel management situation. In order to be complete, all reactors constructed are described, including those that have already been decommissioned. More details of the fuel consumption and spent fuel storage capacity of each installation will be presented in the next sections of this document.

This report is a summary and overview of the scientific investigations of this CRP as carried out in the nine participating countries. The results of corrosion surveillance activities in the individual fuel storage basins of these countries are discussed in detail. On the basis of the knowledge gained from the overall results of this project, a set of Guidelines for Corrosion Protection of Research Reactor Aluminium Clad Spent Nuclear Fuel in Interim Wet Storage were developed and are presented in Chapter 3. 

It must be noted, however, that efforts have been spent by several research groups with the aim of combining the favourable features of monolithic catalysts operated under autothermal conditions (thus favouring the onset in the gas-phase volumes of selective oxidation paths of the alkane fuel), with the development of intrinsically active and selective formulations able to contribute directly or indirectly to the selective production of olefins. A specific mention is deserved by rare earth oxides-based catalysts wherein contributions of the catalyst surface to the formation of ethyl species were reported. " Interestingly, through a detailed comparison of the observed performances of Pt-based and LaMnOs-based monoliths in ethane ODH experiments, Donsi et observed that the use of the perovskite-coated monolith yielded an improvement in ethylene yield. An overview of their results is reported in Fig. 28.6.
