chemical thermodynamics of neptunium and plutonium - U.S. ...

ForewordThis is the fourth volume of a series of expert reviews of the chemical thermodynamicsof key chemical elements in nuclear technology and waste management. The recommendedthermodynamic data are the result of a critical assessment of publishedinformation.The data base system developed at the Data Bank of the OECD Nuclear EnergyAgency (NEA), cf. Section 2.6, ensures consistency not only within the recommendeddata sets on neptunium and plutonium, but also among all the data sets to be publishedin the series.The NEA Data Bank provides a number of services that may be useful to the readerof this book.• The recommended data can be obtained via Internet directly from the NEA DataBank.• The NEA Data Bank maintains a library of computer programs in variousareas. This includes geochemical codes such as PHREEQE, EQ3/6, MINEQL,MINTEQ, PHRQPITZ, etc., in which chemical thermodynamic data like thosepresented in this book are required as the basic input data. These computercodes can be obtained on request from the NEA Data Bank.We’dliketohearfromyou!If you have comments on the NEA TDB reviews, please contact us and tell us whatyou liked, what you didn’t like, and of course about any errors you find in the reviews.See below for information on where to find us.How to contact the NEA TDB projectInformation on the NEA and the TDB project, on-line access to selected data, computerprograms etc., as well as many documents in electronic format, is available athttp://www.nea.fr.For contact with the TDB project coordinator and the authors of the review reports,ix
