means waste in which nuclear material, measured or estimated on the basis of measurements, has been conditioned in such a way (for example, in glass, cement, concrete or bitumen) that it is not suitable for further nuclear use;
- decommissioned
means, when referring to an installation, that it has been verified that all nuclear material subject to Euratom safeguards has been removed and residual structures and equipment essential for using the installation for purposes other than disposal of nuclear material which is no longer subject to Euratom safeguards have been removed or rendered inoperable so that processing or utilization of nuclear material is no longer possible;
- discards to the environment
means nuclear material, measured or estimated on the basis of measurements, that has been irrevocably discarded into the environment as the result of a planned discharge and in such a way that it is not suitable for further use;
- disposal
means the emplacement of waste, spent fuel or any other nuclear material in an installation without the intention of retrieval;
- equivalence criteria
means specific criteria to be fulfilled with regard to the quantity, category, isotopic composition, physical form, chemical form and material state of nuclear material in order to apply the equivalence principle;
- equivalence principle
means that a particular safeguard obligation applying to a quantity of nuclear material may be transferred to another quantity of nuclear material, subject to equivalence criteria;
- hot cell
means a cell or interconnected cells totalling at least 6 m3 in volume with shielding equal to or greater than the equivalent of 0,5 m of concrete, with a density of 3,2 g/cm3 or greater, outfitted with equipment for remote operations;
- installation
means, from the planning stage until it is confirmed as decommissioned:
- item
means an identifiable unit such as a fuel assembly or a fuel pin;
- key measurement point
means a location where nuclear material appears in such a form that it may be measured to determine material flow or inventory, including but not limited to, the places where nuclear material enters, leaves or is stored in, material balance areas;
- Location Outside Facilities
(LOF) means a location not covered under the definition set out in point 27(a) where source material or special fissile material is held or customarily used in amounts of one effective kilogram or less;
- material balance area
(MBA) means an area such that, for the purpose of establishing the material balance:
- material unaccounted for
means the difference between the physical inventory and the book inventory;
- national Location Outside Facilities
means a particular LOF comprising holders of small amounts of nuclear material in line with criteria agreed between the Member States where the material is held and the Commission;
- non-nuclear-weapon Member States
means Belgium, Bulgaria, Czechia, Denmark, Germany, Estonia, Ireland, Greece, Spain, Croatia, Italy, Cyprus, Latvia, Lithuania, Luxembourg, Hungary, Malta, Netherlands, Austria, Poland, Portugal, Romania, Slovenia, Slovakia, Finland, and Sweden;
- nuclear material
means ores, source materials or special fissile materials as defined in Article 197 of the Treaty;
- nuclear-weapon Member State
means France;
- operator
means any person or undertaking, including any organisation, planning to set up or legally responsible for setting up or operating an installation;
- ores
means ores as defined in Article 197, point 4, of the Treaty and as specified in the EAEC Council Regulation No 9;
- physical inventory
means the sum of all the measured batch quantities or derived estimates of batch quantities of nuclear material on hand at a given time within a material balance area, obtained in accordance with specified procedures;
- pool accounting
means a specific accounting method whereby a unique obligation code (pool code) is used to declare book inventories and physical inventory listings to the Commission pursuant to Articles 14 and 15, although the nuclear material may be subject to various particular safeguard obligations;
- proportionality principle
means that, when nuclear material subject to a particular safeguard obligation is mixed or transformed in a given proportion with nuclear material not subject thereto, the product, by-product, waste or losses generated from processing is subject to the particular safeguard obligation in the same proportion;
- retained waste
means waste, generated from processing or from an operational accident, that is measured or estimated on the basis of measurements, that has been transferred to a specific location within the material balance area from which it can be retrieved, and that is deemed to be not recoverable for the time being;
- shipper/receiver difference
means the difference between the quantity of nuclear material in a batch as measured at the receiving material balance area and the quantity as stated by the shipping material balance area;
- site
means an area delimited by the Community and a non-nuclear-weapon Member State, comprising one or more installations, including closed-down installations, as defined in their relevant basic technical characteristics, whereby:
- site representative
means any person, undertaking or entity designated by a non-nuclear-weapon Member State as being responsible for the declaration referred to in Article 6(1);
- source data
means those data, recorded during measurement or calibration or used to derive empirical relationships, which identify nuclear material and provide batch data, including: weight of compounds;
- spent fuel
means nuclear fuel that has been irradiated in and permanently removed from a reactor core;
- third country
means any State which is not a member of the Community;
- under decommissioning
means, when referring to an installation, that activities on dismantling, or recovery and removal of nuclear material or the removing or rendering inoperable of essential equipment are ongoing with the aim of decommissioning the installation;
- waste
means nuclear material in concentrations or forms which make the nuclear material not recoverable for practical or economic reasons, for which no further use is foreseen and which may be disposed of;
