This report is the first in a set of documenting version 7.0 (version 3245.1090 under the old num-
bering system) of the EQ3/6 software package. This set includes:
I. The EQ3/6 Package Overview and Installation Guide (this report).
II. The EQPT User's Guide (Daveler and Wolery, 1992).
III. The EQ3NR Theoretical Manual and User's Guide (Wolery, 1992).
IV. The EQ6 Theoretical Manual and User's Guide (Wolery and Daveler, 1992).
EQ3NR is the speciation-solubility code in the EQ316 package. EQ6 is a reaction path code and
hence deals with the evolution of a water/rock system as reaction progress or time advances.
EQPT is the EQ3/6 data file preprocessor.
The development of EQ3/6 has been supported by a number of programs concerned with geolog-
ic disposal of high level nuclear waste, including the Office of Nuclear Waste Isolation, the Salt
Repository Project Office, the Waste Isolation Pilot Plant (through Sandia National Laboratory),
the Nevada Nuclear Waste Storage Investigations, and the Yucca Mountain Site Characterization
Project. Documentation for the package is aimed at satisfying the requirements of the U.S. Nu-
clear Regulatory Commission for software used for this purpose (Silling, 1983).
The Lawrence Livermore National Laboratory has not certified that EQ3/6 constitutes approved
code for the conduct of quality affecting work for the Yucca Mountain Project.
No source codes or data files are reproduced in this report, nor are any computer media contain-
ing such items a part of this report or any of the other reports documenting this version of EQ3/6.
The software itself must be obtained as described below.
The examples presented in this series of reports correspond to version 7.0 of the software and the
R10 set of supporting thermodynamic data files. As of the date of publication of this report, the
most recent version of the software is version 7.1 (containing bug fixes, but no enhancements),
and the most recent set of data files is R16.
