16.	LINE NUMBER: Sequential number starting with 1 in each report, no gaps.
17.	ITEMS: Each physical inventory line must indicate the number of items involved. If a group of items belonging to the same batch are reported as several lines, the sum of the number of items reported must equal the total number of items in the group. If the lines involve more than one element category, the number of items should be declared in the line(s) for the element category of highest strategic value only (in descending order: P, H, L, N, D, T).
18.	ELEMENT WEIGHT: The weight of the element category referred to in field 12 must be reported. All weights must be reported in grams. The decimal digits appearing in the accounting lines can be reported up to a maximum of three decimal places.
19.	ISOTOPE: This code indicates the fissile isotopes involved and should be used when the weight of fissile isotopes is reported. Use the code G for U-235, K for U-233, and J for a mixture of U-235 and U-233.
20.	FISSILE WEIGHT: Unless otherwise stated in the particular safeguard provisions, the weight of fissile isotopes must only be reported for enriched uranium and category changes involving enriched uranium. All weights must be reported in grams. The decimal digits appearing in the accounting lines can be reported up to a maximum of three decimal places.
21.	OBLIGATION: Indication of any additional obligation assumed by the United Kingdom under a relevant international agreement, to which the qualifying nuclear material is subject (regulation 19). Regulation 19(4) governs the making available of appropriate codes by the ONR.
22.	DOCUMENT: Operator-defined reference to supporting document(s).
23.	CONTAINER ID: Operator-defined container number. Optional data element which can be used in those cases where the container number does not appear in the batch designation.
24.	CORRECTION: Corrections have to be made by deleting the wrong line(s) and adding the correct one(s), where appropriate. The following codes must be used:

	Code		Explanation
	D		Deletion. The line to be deleted must be identified by indicating in field 25 the report number (4), in field 26 the line number (16) and in field 29 the CRC (28) which were declared for the original line. Other fields need not be reported.
	A		Addition (forming part of a deletion/addition pair). The correct line must be reported with all data fields including the ‘previous report’ field (25) and the ‘previous line’ field (26). The ‘previous line’ field (26) must contain the line number (16) of the line being replaced by the deletion/addition pair.
	L		Late line (stand-alone addition). The late line to be added must be reported with all data fields, including the ‘previous report’ field (25). The ‘previous report’ field (25) must contain the report number (4) of the report in which the late line should have been included.

25.	PREVIOUS REPORT: Indicate the report number (4) of the line to be corrected.
26.	PREVIOUS LINE: For deletions, or additions forming part of a deletion/addition pair, indicate the line number (16) of the line to be corrected.
27.	COMMENT: Free-text comment field for short comments by operator.
28.	CRC: Hash code of line for quality control purposes. The ONR must inform the operator of the algorithm to be used.
29.	PREVIOUS CRC: Hash code of the line to be corrected.
GENERAL REMARKS CONCERNING THE COMPLETION OF THE REPORTS If, on the date the physical inventory was taken, there was no qualifying nuclear material in the material balance area, only labels from 1 to 7, 16, 17 and 28 above should be completed on the report.
General remarks 2, 3, 4, 5 and 6 at the end of Part 2 apply to this Part as appropriate.
This form, duly completed and signed, must be sent to the ONR in accordance with regulation 35.
