' P*Citiq NOTICE OF VIOLATION General Electric Company Docket No. 70-1113 Wilmington Manufacturing Department License No. SNM-1097 As a result of the inspection conducted on June 13 - 17, 1983, and in accordance with the NRC Enforcement Policy, 47 FR 9987 (March 9, 1982), the following violations were identified.
A. Licerise Condition 2.1 requires the licensee to follow the Fundamental Nuclear Material Control Plan dated June 24, 1977, as amended according to the schedule of pages dated December 23, 1982, transmitted by his letter from Charles M. Vaughan to L. J. Evans dated December 23, 1982; an_d_as may be revised in accordance with the provisions of 10 CFR 70.32(c).1 Contrary to the above, the licensee failed to investigate and reconcile shipper-receiver differences on individual containers that were statisti-cally si,gnificant for one cylinder from a shipment of uranium hexafluoride received March 18, 1983, two cylinders from a shipment of uranium hexa-fluoride received April 7,1983, and one cylinder from a shipment of uranium hexafluoride received April 11, 1983.
This is a Severity' Level V Violation (Supplement III).
- 8. 10 CFR 70.51(c) requires the licensee to "... establish, maintain, and follow written material control and accounting procedures..."
Contrary to the above, the licensee failed '.o follow procedure 109, " Nuclear l
Material Receipts", (revision 7 - issued March 23, 1983). The procedure state 3: "UF6 cylinders which have assigned gross weight differences _ greater than _
l(as compared to the shipper's tally out sheet or other I official material transfer document and the WMD assigned, weight)_must be l reweighed. If after reweighing, the difference exceedsi the l cylinder must be placed on hold until a detailed shipper i receiver difference l analysis is performed." On April 11, 1983, and May 3, 1983, the licensee l received uranium hexafluoride cylinders that,had gross _ weight differences 1 (when compared to the shipper) in excess oft,, ,
The licensee j l failed to reweigh the cylinders in accordance with the written procedure.
This is a Severity Level V Violation (Supplement III).

- 2. Records and Reports A review was made to determine the accuracy of the licensse's accountability records. A sampling of entries posted to the records during the period March 1 through May 31, 1983, was selected for review. Entries representing ;
each type of transaction (i.e., receipts, shipments, and losses) were l included in the test. Each transaction was traced to the Nuclear Material Transaction Report (Form DOE /NRC-741) and to the applicable supporting j documentation such as transfer forms, measurement worksheets, and shipper l invoices. The transactions reviewed were found to be properly supported and I accurately posted to the accountability records.
- 3. Shipping and Receiving )
The licensee's program of accounting for special nuclear material (SNM) shipped and received during the period June 1982 through May 1983 was inspected. The inspection consisted of a review of the nuclear material accounting procedures for shipping and receiving, a selected examination of the licensee's records pertaining to specific transactions and the source of the data used to generate those records, a review of the licensee's system for evaluating shipper - re'ceiver differences, and an examination of the l methods used for calculating limits of error associated with shipments and receipts. The records selected for review pertained to transactions in- l volving receipts of uranium hexafluoride. 1

s As uranium;hexafluoride is received, supporting documentation is generated by Fuel Support Operation and by the Measurement.s and Statistics Section.
These organizations are responsible for checking receiving documentation, seal identification and condition, item piece count and identification, and for assuring that quantitative measurement data are obtained. The uranium factor, isotopic (U-235) factor, and metallic impurities correction are reported by Ledoux, an off-site laboratory. The Records and. Reports Section uses these data to , complete the Nuclear Materia'l . Transaction Reports (Form NRC-741). The NRC-741 forms were receipted and returned within the specified time requirements.
The licensee calculates limits of error for each receipt of uranium hexafluoride on an item basis and on a shipment basis. A review of the licensee's methods for calculating limits of error showed that appropriate statistical techniques were being employed. Shipper - receiver differences (SRDs) for uranium hexafluoride receipts are evaluated on an item basis and on a shipment basis utilizing the computed limits of error. During this inspection, four instances were found where statistically significant SRDs occured for individual cylinders of uranium hexafluoride receipts and .the licensee did not take appropriate investigative action or attempt to-reconcile the difference. 'More specifically, the four instances were:
- a. A statistically significant SRD was detected in container GEW329 of receipt BWA-YLJ 554 (received March 18, 1983) for both grams uranium and grams U-235. The difference was attributed to a gross weight discrepancy in the heel.
- b. A statistically significant SRD was detected in container GEW117 of receipt BWA-YLJ 565 (received April 7,1983) for grams U-235. The difference was attributed to a significant difference in enrichment between the 1,1censee and the shipper.
- c. A statistically significant SRD was detected in container GEW364, also of receipt BWA-YLJ 565, for grams U-235. The difference was attributed to a significant difference in enrichment between the licensee and the shipper.
- d. A statistically significant SRD was detected in container GEW213 of receipt BWA-YLJ 567 (received April 11, 1983) for grams U-235. The difference was attributed to a gross weight discrepancy and a significant difference in enrichment between the licensee and the shipper.
In each of the four instances, the licensee either did not take any in-vestigative action or the investigative action as described in the licensee's " Shipper / Receiver Differences Report" did not address the significant differences in the ino. idual cylinders. In all four instances, no attempt was made by the licensee to esolve the significant SRO i t exw n _ . : ~ m!

.I _ J In one of the instances (BWA-YLJ 554), the i Manager, L&NMM was not notified in that he did not sign the
" Shipper / Receiver Differences Report" to acknesledge notification when the l statistically significant SRD was observed. The licensee's failure to investigate and reconcile statistically significant SR0s is a violation (83-17-01).
The licensee's program to monitor cumulative SR0s for receipts of uranium hexafluoride was also reviewed. The licensee employes cumulative sum (CUSUM) charts to evaluate the cumulative SRD. This area will be examined in more detail in a future inspection.
A second problem was detected in the licensee's program for receiving uranium hexafluoride. According to procedure 109, the licensee is to reweigh uranium hexafluoride cylinders when the difference in gross weight (as compared to the shipper) exceedsI The procedure also states that "if after reweighing, the difference still exceeds L. . the cylinder must be placed on hold until a detailed shipper-receiver analysis is performed". On two-different occasions, container GEW213 of receipt BWA-YLJ 567 (received April 11, 1983) and container GEW140 of receipt BWA-YLJ 577 (received May 3,1983), the licensee received uranium hexa-fluoride cylinders that had gross weight differences (when compared to the shipper) in excess ofI and failed to reweigh them. The original gross weight was used in completing the NRC-741 Form. Thus if the cylinders were reweighed, and the reweigh check sheets were lost or misplaced by the licensee, the revised gross weight would have had to have been the same as the original gross weight from the first weighing. The cylinders would have had to have been placed on hold until a detailed shipper-receiver difference analysis could be performed in accordance with the written procedure.
The licensee could, not furnish documentation of a detailed shipper-receiver analysis nor could the licensee furnish documentation showing that the cylinders were reweighed. In addition, the gross weight discrepancy of container GEW213 was a major cause of the statistically significant SRO for this cylinder. Furthermore, this stat'istically significant SRD was not investigated or reconciled by the licensee, as referenced in violation 83-17-01 above. The licensee's failure to reweigh cylinders of uranium hexafluoride in accordance with the written procedure is a violation (83-17-02).
Another area of concern uncovered during this inspection involved statistically significant SRDs caused by discrepancies in the gross heel weight. Upon receipt of uranium hexafluoride cylinders by the licensee, they are completely emptied except for some residual material in the bottom of the cylinder referred to as a heel. The licensee ships the heel back to the gaseous diffusion plant with a measured gross heel weight, determined prior to shipment. The gaseous diffusion plant, after receipt of the heels, gross weighs each heel. The gross heel weight, as determined by the gaseous diffusion plant, was found in a number of cases to be .significantly l dif ferent from the licensee's gross heel weight. The gaseous diffusion plant, however, does not reconcile'significant SRDs. Thus, when the gaseous diffusion plant refills the cylinders with uranium hexafluoride to ship back i

to the licensee, this gross heel weight discrepancy can cause significant SRDs for the licensee wnich at the present time they-are unable to resolve.
This item is deemed an inspector follow-up item, pending further discussicns between the licensee and the NRC (83-17-03). It should be noted that this problem was discussed in Region II Inspection Report 70-1113/79-09 and assistance from the NRC Office of NMSS was requested to resolve this problem with the DOE facilities. Discussions were held between NMSS and 00E con-cerning this matter and means of re^ solution were to be further explored. It is evident from the current . inspection findings that resolution of this matter has not been achieved. Therefore, NMSS will be requested to contact DOE again in regards to this matter.
- 4. Internal Control ,
The licensee's system of storage and internal control established to provide current knowledge of the identity, quantity, and location of the SNM D contained in discrete items y Ld containers within the plant was inspected.
