Environmental
Geochemistry and Radioactive Waste Disposal
|
| Overview |
| The
lectures in this final week of the course tie together many of the
concepts (e.g., solubility, sorption, pe-pH diagrams, clay minerals) we have learned and
apply them to an important societal problem
- the safe disposal of radioactive waste. We start with a brief review of
the problem, and then discuss some of the ways that aqueous geochemistry
can help in finding a solution. |
| Objectives |
 | Define types of nuclear waste and their
characteristics. |
| Consider the pros and cons of
geological burial of nuclear waste. |
| Understand the geochemistry of uranium. |
| Understand the geochemistry of
fission and neutron capture products (Pu,Np, Am). |
| Learn about analog studies, in
particular the Oklo, Gabon reactor. |

The following is
suggested reading in support of this lecture, but is not
required.
| Chapter 24 in Faure, G.
(1998) Principles and Applications of Geochemistry,
2nd. ed., Prentice-Hall, Upper Saddle River, New
Jersey, 461-484. |
| Chapter 13 in Langmuir,
D. (1997) Aqueous Environmental Geochemistry,
Prentice-Hall, Upper Saddle River, New Jersey,
