Ceramic Mineral Waste-Forms for Nuclear Waste Immobilization

Nuclear waste forms for actinides.

The disposition of actinides, most recently 239Pu from dismantled nuclear weapons, requires effective containment of waste generated by the nuclear fuel cycle. Because actinides (e.g., 239Pu and 237Np) are long-lived, they have a major impact on risk assessments of geologic repositories. Thus, demonstrable, long-term chemical and mechanical durability are essential properties of waste forms for...

Ceramic Package Fabrication for YMP Nuclear Waste Disposal

Nuclear waste disposal.

-Experiments are described in which dose-response data have been obtained for EMT6 mouse tumour cells growing in vivo and exposed to various cytotoxic agents. A comparison has been made of the response of solid tumours in the flank and of rapidly growing lung nodules. The results are discussed with regard to their cell kinetic implications and compared with our results for the chemosensitivity ...

Nuclear waste risk perceptions

1. Introduction The siting of spent nuclear fuel (SNF) is a highly controversial issue in most countries. So far, Finland [6; 9] and Sweden have been exceptions; for reviews see Sjöberg [13; 15]. The corporation responsible for finding a site and building a repository for SNF in Sweden, SKB, managed to find two promising host communities in 2001: Östhammar and Oskarshamn, two small communities ...

incineration of nuclear waste

Since the end of 1989, ECN renewed its interest in incineration of transuranium elements and fission products. With respect to the transmutation of minor actinides ECN was requested by the clutch government to start a study of a scenario based upon thermal reactors and to work on incineration by means of new fast reactor designs. There are also plans for a study on the possible use of accelerat...
