General

Description of the accountancy system used to record and report accountancy data, including method of recording accountancy data and establishing material balance;

Main inventory changes

Description of typical inventory changes e.g. receipts (including method of dealing with the shipper/receiver differences and subsequent accounting corrections), shipments and waste related inventory changes, including a description of how these changes are determined. Corresponding operational records and source data (e.g. receiving and shipping forms, the initial recording of measurements and measurement control sheets) shall be identified;

Physical inventory

Description of procedures, scheduled frequency, methods of operator’s inventory taking (both for the number of items as well as their nuclear material weights), including relevant assay methods and expected accuracy, access to nuclear material, possible methods for the physical verification of fresh and irradiated nuclear materials;

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;

anticipated types of inventory changes;

possibility to use this measurement point for physical inventory taking;

physical and chemical form of nuclear material;

nuclear material containers;

sampling procedures and equipment used;

measurement methods and equipment;

source and level of random and systematic errors (weight, volume, sampling, non-destructive assay);

technique and frequency of calibration of equipment used;

method of converting source data to batch data;

means of batch identification;

anticipated batch flow per year;

anticipated number of inventory batches with related storage capacity;

anticipated number of items per flow;

type, composition and quantity of nuclear material per batch, estimated weight of each element of nuclear material, the isotopic composition when appropriate and form of nuclear material.

key events of the decommissioning plan;

removal and recovery of nuclear material. Provide a plan containing estimates of how, where and when nuclear material will 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 will be accounted for;

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