installation and equipment decontamination and subsequent nuclear material recovery;

installation and equipment clean-out including means of ensuring vessels are empty.

General

Source data (e.g. shipping and receiving forms, internal transfer documents, physical inventory forms, the initial recording of measurements and measurement control sheets). Procedures for making adjustments and corrections (indicating how the adjustments are authorized and substantiated);

Receipts (including method of dealing with shipper/receiver differences and subsequent accounting corrections; checks and measurements used to confirm nuclear material content);

Shipments (products, waste);

Transfers to retained waste (method of establishing quantities, method and envisaged period of storage, possible subsequent uses of retained waste);

Discards to the environment (method of establishing quantities, method of discharge);

Other inventory changes, e.g. transfers to conditioned waste, unmeasured losses (method of establishing quantities);

Physical inventory

Description of procedures, scheduled frequency, estimated distribution of nuclear material, methods of operator’s inventory taking (both for the number of items as well as their nuclear material weights, including relevant assay method), accessibility and possible verification method for nuclear material, expected accuracy, and access to nuclear material. In particular the description of procedures shall also provide the basic inventory approach to be used, i.e. planning, organizing, and conducting the inventory taking, primary responsibility for the inventory, process clean-out, accountancy of process residual hold-up;

Operational and accounting records (including internal transfer forms, method of adjustment or correction, control measures and responsibility for records). Description of how these records are maintained, including when an adjustment or correction is needed, place where the records can be consulted, retention time and language;

Particular accounting provisions

Description of particular provisions, e.g. for the designation of batch IDs and methods for preventing, detecting and timely fixing of accounting discrepancies.

description of location, type, identification;

expected types of inventory change at this measurement point and possibility to use this measurement point for physical inventory taking;

chemical and physical form of material;

sampling procedure and equipment used;

measurement/analytical method and equipment used;

source and level of random and systematic errors (weighing, volume, sampling, analytical);

calculative and error propagation technique;

technique and frequency of calibration of equipment used;

programme for the continuing appraisal of the accuracy of weight, volume, sampling techniques and measurement methods;

programme for statistical evaluation of data from (h) and (i).

shipper/receiver differences;

book inventory;

physical inventory;

material unaccounted for (MUF).

key events of the decommissioning plan;

removal and recovery of nuclear material. Provide a plan containing estimates of how, where and when nuclear material shall be recovered and/or removed (e.g. loose material consolidated into items, removal of items, recovery/removal of material from decontamination activities, and recovery/removal of nuclear material in waste) and how it shall be accounted for;

removing or rendering inoperable of equipment essential for the functioning of the installation, for handling or storing nuclear material.
