Explanation
A measure of the radioactivity of a substance, measured in Becquerel (Bq).
A previously stated item.
The circumferential variation of neutron flux within the reactor core.
The fundamental status of the proposal and issues, which are explored in more
detail in this document.
This identifies activities that could impact on nuclear safety and demonstrates
that the licensee has adequate organisational structures, resources and
competences to manage safety effectively.
The areas within the nuclear island that are not the primary circuit.
Best Available Techniques (BAT) are required to be considered (under EC
Directive 96/61) in order to avoid or reduce emissions resulting from certain
installations and to reduce the impact on the environment as a whole. Use of
BAT is required by the Environment Agency when licensing the major potentially
polluting industries under the IPPC legislative regime. BAT takes into account the
balance between the costs and environmental benefits.
A decision-making procedure that takes into account the protection and
conservation of the environment. It justifies the option that provides the most
benefit or the least damage to the environment as a whole, at acceptable cost, in
the long term as well as the short term.
The testing of a process facility prior to routine or normal operation that ensures
that all equipment works as intended prior to full active operation.
The process by which waste is physically or chemically processed to make it
disposable.
Layers of defence intended to prevent radioactive materials reaching the
environment if the confinement is breached.
A way of continuing an operation or group of operations after an unwanted event
has occurred. A safety control measure that forms part of a series of safety
control measures designed to prevent the occurrence of an accident.
A defined area in which specific protection measures and safety provisions are
required for controlling exposures to or preventing the spread of contamination
during normal working conditions, and preventing or limiting the extent of
potential exposures.
Forms of waste from a nuclear facility that are not radioactive. The Controlled
Waste Regulations 1992 defines Controlled Waste as household, industrial and
commercial waste.
The transfer of heat and moisture by the movement of a fluid.
