How to access the restricted TDB web pages

Access to the TDB select data files

Anyone from an NEA member country can obtain a password and a user name to access the TDB selected datasets. If you do not have a user name and a password already, you can obtain it by filling out the online registration form and sending an e-mail to . You will then be sent a user name and password by e-mail. Please allow for a minimum of 24 hours (one working day) after you receive the e-mail for the registration to be effective.

All other publicly available information can be found in the published review reports.

Access for members of organisational units and review groups

Access to the TDB review group and organisational unit web pages is restricted to the members of the respective groups. Currently, the web pages for the Np/Pu review, the Ni review, the Se review, the U/Am/Tc/Np/Pu review, the Zr review, the Simple Organic Ligands review and the TDB Management Board and the TDB Executive Group for phase II are restricted in this way. Hence, although the final reviews are published in the open literature, access to the intermediate results and reports is restricted to the members of the TDB Executive Group, Management Board and the members of the respective review teams. This is due to the problems encountered during the work on earlier review reports, when preliminary results found their way into the open literature and were incorrectly quoted as being the final values. In any case, being unfinished, the material on the pages of the active review teams is not really of any public interest.

To access the restricted TDB web pages for the review groups or organisational units you must:

be a member of the review group or organisational unit which the restricted web pages address, or belong to the Management Board or Executive Group. These registrations are made at the NEA for the people concerned; and
have a valid user name and password for accessing the TDB database services. This can be obtained by sending an e-mail to .

If you already have a user name and password for the TDB database access services, there is no need to obtain new login details. Use what your existing user name and password to access the restricted web pages. If you experience problems, please send an e-mail to .
