egulatory body. 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.
release. See discharge.
remedial action. Action taken when a specified action level is exceeded, to reduce a radiation
dose that might otherwise be received, in an intervention situation involving chronic exposure.
Examples are: (a) actions which include decontamination, waste removal and environmental
restoration of a site during decommissioning and/or closure efforts; (b) actions taken beyond
stabilization of tailings impoundments to allow for other uses of the area or to restore the area to
near pristine conditions.
remediation. See cleanup.
repository. A nuclear facility where waste is emplaced for disposal.
repository, near surface. A facility for disposal of radioactive waste located at or within a few
tens of metres from the earth’s surface.
restoration. See cleanup.
retardation. A reduction in the rate of radionuclide movement through the soil due to the
interaction (e.g. by sorption) with an immobile matrix.
retardation coefficient, Rd. A measure of capability of porous media to impede the movement of
a particular radionuclide being carried by fluid.
retrievability. The ability to remove waste from where it has been emplaced.
risk. A multiattribute quantity expressing hazard, danger or chance of harmful or injurious
consequences associated with actual or potential exposures. It relates to quantities such as the
probability that specific deleterious consequences may arise and the magnitude and character of
such consequences. (2) The combination of the frequency, or probability, of occurrence and the
consequence of a specified hazardous event. The concept of risk always has two elements: the
frequency or probability with which a hazardous event occurs and the consequences of the
hazardous event. Risk = Probability x Consequence.
risk assessment. See assessment, risk.
rock. In geology, any mass of mineral matter, whether consolidated or not, which forms part of
the earth’s crust. Rocks may consist of only one mineral species, in which case they are called
monomineralic but they usually consist of several mineral species.
RWMAC The Radioactive Waste Management Advisory Committee (RWMAC) was established
in 1978 to offer independent advice to Ministers on radioactive waste management issues.
Members of the Committee were drawn from a wide range of backgrounds and specialisms
including radioactive waste management, radiological protection, earth sciences, environmental
law & planning, medical physics and social sciences. Each year until 2004, RWMAC undertook
a programme of work commissioned by Government Ministers.
safety case. An integrated collection of arguments and evidence to demonstrate the safety of a
facility. This will normally include a safety assessment, but could also typically include information
(including supporting evidence and reasoning) on the robustness and reliability of the safety
assessment and the assumptions made therein.
Application for disposal of LLW including HV-VLLW under RSA 1993,
