NEWMDB - The IAEA Nuclear Waste Management Database IAEA - International Atomic Energy Agency

Glossary of Terms


radio button
a round button with associated text (a label), an icon, or an image that indicates a choice the user can make by selecting the button

A computer application typically uses radio buttons in a group box to permit the user to choose from a set of related, but mutually exclusive options. For example, the application might present a group of radio buttons from which the user can select a format preference for text selected. The user could select a left-aligned, right-aligned, or centred format by selecting the corresponding radio button. Typically, the user can select only one option at a time from a set of radio buttons.
radionuclide separation
a Department of Energy (United States of America) activity to separate wastes containing radionuclides from wastes containing only non-radiologically hazardous materials. (Federal Facility Compliance Act of 1992,
reactor operations
used in the NEWMDB to indicate waste arising from the operation and maintenance of nuclear reactors, both power and research reactors (includes waste from commissioning operations and generated from hot cell work with reactor components, excludes decommissioning waste)
Public (non-authorized) users of the NEWMDB must register by completing a registration form. As a minimum, the user's e-mail address must be provided. Some additional (optional) information is also requested at time of registration.
registered user
any non-authorized user (see authorization)

At the request of some Member States, the IAEA maintains a log of who accessed NEWMDB reports and when they were accessed. To track access, authorized Users (such as Country Co-ordinators) login to identify themselves. Other (Public) users must first register.
an all-encompassing public policy term that includes various political and economic issues and ideas; government regulations include two distinct categories -- economic regulations and social regulations.

Economic regulations generally cover sectors of an economy such as energy, communications, transportation, and financial institutions. These regulations usually take the form of overt barriers to entry or exit, licensing and tarif laws, and price and wage controls.

Social regulations include statues or rules that are intended to protect citizen or worker health and safety, accomplish environmental and other aesthetic goals, or promote civil rights objectives.

regulatory body
1. an authority or a system of authorities designated by the government of a State as having legal authority for conducting the regulatory process, including issuing authorizations, and thereby for regulating the siting, design, construction, commissioning, operation, closure, decommissioning and, if required, subsequent institutional control of the nuclear facilities (e.g. near surface repositories) or specific aspects thereof.

2. any body or bodies given the legal authority by the Contracting Party to regulate any aspect of the safety of spent fuel or radioactive waste management including the granting of licences. [Joint Convention definition - not recommended for IAEA publications]
regulatory control
any form of control applied to facilities or activities by a regulatory body for reasons related to protection or safety
1. see discharge

2. removal from regulatory control
see release
measures carried out to reduce the radiation exposure from existing contamination through actions applied to the contamination itself (the source) or to the exposure pathways to humans
Report Co-ordinator
a person designated by a Country Co-ordinator to assist with reporting to the NEWMDB

Country Co-ordinators define the number and structure of Reporting Groups for reporting to the NEWMDB. Each Reporting Group must be assigned a Report Co-ordinator, who has read and write access for all information for the Reporting Group. A Report Co-ordinator grants permission to Waste Experts
Reporting Group
used in the NEWMDB to indicate that a submission is divided into parts, where each part is a called a Reporting Group - see
a nuclear facility where waste is emplaced for disposal
a process or operation, the purpose of which is to extract radioactive isotopes from spent fuel for further use
a waste treatment method that typically uses water to wash off unbound radioactive contamination from tanks and other waste containers
a default set of permissions that define a user's access to a database (both registered users and Public Users)

There are two types of permissions: explicit and implicit. Explicit permissions are those permissions that are granted directly to a user account; no other users are affected. Implicit permissions are those permissions that are granted to a group account. Adding a user to that group grants the group's permissions to that user; removing a user from the group takes away the group's permissions from that user.
