Letter, James G.
Partlow to C.
E.
- Bowers, dated January 3, 1980 Gentlemen:
The referenced letter requested that UNC modify our Fundamental Nuclear Material Control Plan to clarify that " book record" includes both the total plant and subsidiary material control area records.
Accordingly, we have modified section 5.12 of the FNMC, and are submitting it with this letter.
Also attached are minor administrative changes to section 6.1 of the FNMC.
As none of the submitted changes decrease the effectiveness of the material control and accounting program, no license fee is being submitted, consistent with your letter of March 20, 1979.
Very truly yours, IIWh R.
J.

505-4 Change 8 5.10 Materials on Inventory Batchwise-operated equipment will be inventoried as empty and clean.
Material in the extraction system will be recycled to a constant level.
Extraction feed and product tanks and the evapor-ater product tank will be recirculated to provide homogeneity prior to sampling and measurement.
These tanks will vary in contents depending on prior production.
Their maximum capacity is given below:
1-D-41 Extraction Feed Tank 1690 gal.
1-D-9's Extraction Feed Tank 270 gal.
1-D-10's Evaporator Feed Tanks 180 gal.
1-D-16 Evaporator Product Tank 45 gal.
1-D-24B Filtrate Tank 520 gal.
Tanks used for volume measurement, containing Borosilicate Raschig Rings, will be calibrated at least once per year.
All tanks inventoried as other than empty will have undergone calibration within the previous twelve months.
For inventory purposes in-process material will be reduced to a minimum.
Chemical assays will be run on all in-process material where possible.
Material in storage, which is satisfactorily sealed, will be inventoried at its measured value.
5.11 Inventory Verification The identity and location of all items is verified independently by at least two members of the inventory team.
The Inventory Control Roster is also checked against the ICA and MBA records for an additional verification of the identity and location of all items.
5.12 Inventory Reconciliation Resolution of discrepancies between primary and and secondary accounts and the physical inventory are the responsibility of the Manager, Nuclear Material Control.
Discrepancies will be verified before reconciling primary records to the physical inventory.
All inventories will be reconciled and the results reported to the USNRC within 30 days from the start of the inventory.
Both primary (total plant) and secondary (MBA) records will be adjusted to the results of the physical inventory at the time of reconciliation, i

506-4 Change 8 6.1.2 Accounting Procedures An Accounting Procedure Manual shall be prepared and periodically updated by the Manager, QA.
6.1.3 Source Data Source data used as the basis for original entry to the accounting records are NRC/ DOE 741 trans-fer documents for the accounting system and Material Balance Area (MBA) Transfer Sheets for the MBA and ICA systems.
6.1.4 Adjustments to Records Adjustrents to prior recorded values to the SNM accounting records are made by means of the NRC/
DOE 741 Transfer Document supported by a memo-randum with the approval of the Manager, Nuclear Material Control or the Manager, QA.
Adjustments to prior recorded values to the MBA records are made by means of the MBA Adjustment Sheet prepared under the direction of, and the approval of, the Manager, QA or Manager, Nuclear Material Control.
6.1.5 Bias Adjustments Bias Adjustments for measurements are incorporated into the accounting system in the same manner as described in section 6.1.6 except the supporting memorandum must be approved by the Plant chemist or the QA Engineer as well as the Manager, QA.
6.1.6 Inventory Reconciliation The sum of the physical inventory values for ICA
- 1, MBA #2, and ICA #3 represent the physical inventory for the entire plant.
ICA #1, MBA #2, and ICA #3 accounts are adjusted to reflect the actual physical inventory for the respective area.
The Transfer Journal and associated Ledgers are also adjusted to the total plant physical inventory by booking the difference between the book balance and the physical inventory as MUF.
The inventory difference is booked by means of an NRC/ DOE 741 transfer document.
The ID booked is approved by the Manager, NMC.
