Part 4 PHYSICAL INVENTORY LISTING (PIL)I1

MBA:

Code of the reporting material balance area. This code is notified to the qualifying nuclear facility concerned by the ONR.

REPORT TYPE:

P for physical inventory listings.

REPORT DATE:

Date on which the report was completed.

REPORT NUMBER:

Sequential number, no gaps.

PIT DATE:

Day, month and year when the physical inventory was taken, reflecting the situation at 24.00.

LINE COUNT:

Total number of lines reported.

REPORTING PERSON:

Name of person responsible for report.

PIL_ITEM_ID:

Sequential number, common to all PIL lines related to the same physical object.

BATCH:

If batch follow-up is required in the particular safeguard provisions, the batch designation previously used for the batch in an inventory change report or in a previous physical inventory listing must be used.

KMP:

Key measurement point. The codes are notified to the qualifying nuclear facility concerned in the particular safeguard provisions or otherwise in writing. If no code has been specified, ‘&’ should be used.

MEASUREMENT:

The basis on which the quantity of qualifying nuclear material reported was established has to be indicated. One of the following codes must be used:

ELEMENT CATEGORY:

The following codes must be used:

High enriched uranium

(20% enrichment and above)

Low enriched uranium

(higher than natural and less than 20% enrichment)

MATERIAL FORM:

The following codes must be used:

MATERIAL CONTAINER:

The following codes must be used:

MATERIAL STATE:

The following codes must be used:

LINE NUMBER:

Sequential number starting with 1 in each report, no gaps.

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).

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.

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.

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.

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.

DOCUMENT:

Operator-defined reference to supporting document(s).

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.

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:

PREVIOUS REPORT:

Indicate the report number (4) of the line to be corrected.

PREVIOUS LINE:

For deletions, or additions forming part of a deletion/addition pair, indicate the line number (16) of the line to be corrected.

COMMENT:

Free-text comment field for short comments by operator.

CRC:

Hash code of line for quality control purposes. The ONR must inform the operator of the algorithm to be used.

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.
