SUMMARY

OF FINDINGS Enforcement Action: None -

Licensee Action on Previously Identified Enforcement Items The item.of noncompliance identified in the previous inspection, December 3-7, 1973, pertaining.to the licensee's failure to comply with the 1.5 kg. LDfUF requirement of License Condition 3.2 was not within the scope of this inspection. The status of this item will'be inspected at a future date.

Licensee actions on items of non-compliance identified in the, inspection of February 21-23, 1973, and March 12-16, 1973 have been as follows:

1. License Condition 3.4 - A report, dated February 15, 1973 was issued by the licensee to comply with this license condition, but the report did

. not include a quantitative calculation of limits of error of the measurement system.

Status - A report dated February 1974 was prepared by the Manager, Administration and Accountability, to comply with License Condition 3.4.

The report contains quantitative calculations of' limits of error. This

. item of noncompliance is considered corrected.

2. License Condition 3.7 - A rep' ort of the results of the licensee measuremen,t evaluation was not sub=itted to AEC, Headquarters within six months after commencing operations on the FFIF project.

Status - This item was partially resolved in a series of verbal and written communciations between the licensee and Licensing which terminated in April 1973'. Revised license conditions dated May 5, 1973 ,were

, subsequently issued, and this item of non-compliance is no longer applicable.

3. License Condition 6.5 - The licensee was not closing a material balance around plutonium in process at intervals not to. exceed thirty days. (This requirement is now contained in License Condition 6.1 of Amendment No.

i HPP-1)'.

Status - The licensee has closed material balances around plutonium, based on physical inventories, at intervals not exceeding thirty days since May 1973. This item is considered corrected.

4. License Condition 7.1 - Material balance area and plant records were not being reconciled at the end of each accounting period. -

Status - Material balance area and plant records are being reconciled monthly. This item is considered corrected.

C. Cender, Safeguards Clerk Scope of Inspection The inspection covered those license conditions and appropriate regulations of 10 CFR Part 70 that were not covered in the inspection of December 5-7, 1973. Conditions inspected were 1.0, 2.0, 3.4 only of 3.0, 4.0, 5.0, 6.4 only of 6.0, 7.0, and 8.0. Measurements and statistical controls and inventory were in general omitted since they have been recently covered.

Facility Organization (License' Condition 1.0)

The Manager, Administration and Accountability, delegated by the Cimarron Facility manager, continues to enforce, develop, and revise the~special nuclear materials control system.

Nuclear material control procedures are formally approved by the Cimarron

  • Facility Manager, and the Manager of Administratira andthe Accountability Safeguards! at , .

procedures are reviewed and updated, if necessary, on an annual basis or as revisions are required. The nuclear material control procedures are not kept in a separate manual, but are an integral portion of a multivolume collection of all procedures for the Cimarron facility.

  • The organization of the nuclear materials control system'is considered to be satisfactory.

Facility Operation (License Condition 2.0)'

l The Plutonium Facility continues to maintain sever NBA's as described in the l

repcrt for the previous inspection, December 5-7, 1973.

To improve MBA control, the licensee has recently There added are six Safeguards such clerks, Clerks and to the staff of the Safeguards specialist.

one will be on duty in the plutonium facility durfing all operating shif ts.

Principle duty of the clerks is to be present during all transfers of material from one MBA .to another to verify the physical morement and correct completion of the transfer forms by the MBA custodians. Implementation of this system will begin on March 11, 1974.

4 6 . .

The licensee's facility operation is satisfcetary.

Hessurements and Statistical Controls (License Condition 3.4 only)

The Manager, Administration, and Accountability, performed and documented an annual review, intended to comply with the license condition. The review consists of ssmple sets of calculations illustrating the method of calculating the plutonium MUF for the overall plant. No conclusions are drawn concerning the data. The review, while it complys with the letter of-the license condition, circumvents the intent of the requirement.

- l 8 The review is similar in format and conten't to that made to comply with the identical' license condition for the uranium facility. The licensee is '

considered to be in noncompliance for an unsatisfactory uranium facility annual review. However, in the case 6f the plutonium plant, all limit of error data are updated and examined month 19 in connection with physical inventories, and the licensee must provide the AEC with probable causes and corrective actions for excessive limits of error. For this reason the '

licensee's annual review is considered to be in compliance.

Shipping and Receiving (License Condition 4.0)

The limits of error for all major shipments and receipts for the period March 1973 to February 1974 were examined. .

The completed AEC-741 forms for plutonium nitrate receipt numbers 4-9 were inspected. The receiver's limits of error for plutonium and the fissile I topes were recorded on all the forms. Thew 1-Pits of error averaged 1 of an individual receipt, normally abou ,~000. grams of plutonium.

ipper-receiver differences were all well it a the receiver limits of error. ,F the six receipts examined, the net shipper-receiver difference was on1 79- grams of plutonium which is 0.08% of the 240,000 grams of

. plutoni eceived.

l The licensee has modified his method of measuring plutonium nitrate receipts

'

  • since the inspection of March 12, 1974. The receipt measurement is again being based on the analyses of samples taken from individual bottles, rather

- than on the analyses of samples taken from the combined contents of all the bottles in the shipment in the plutonium nitrate weigh tank. A single sample is taken from each of the ten or twelve bottles in the shipment, and duplicate samples are taken from two of the bottles. All samples are analyzed by

- amperometric titration. The assay for the shipment is determined from the

- two sets of duplicates. The single analyses from the remaining bottles serve to detect any significant assay differences among bottles from the same lot.

The limit of error for the shipment is calculated by statistically combining the LE of the assay method and the LE of the weigh scale. This combined LE for the shipment is calculated by the safeguards analyst and transmitted to '

. the accountability clerk for entry on the AEC-741.

i Records and Reports (License Condition 7.0)

The licensee's records' system provides sufficient information to maintain a material balance around cach MBA and ~the total plant as required by 7.1. AEC was abic to reconcile MBA balances to plant records for the months of September, October, November, and December 1973 without difficulty.

Measured plutonium discards and M'JF quantities have been reported monthly by the Manascr, Administration and Accountability, as required by 7.2. AEC-742, Material Status Report forms, have been sent monthly to RO:111 as' required.

~

Ma'agement n of Materials *Contro1* System YLicense Condition 8.0)

A management review, independent of the Manager, Administratio'n and Accountability, was made during the inspection period to comply with License Condition 8.1. The review was dated November 10, 1973 and addressed to the Cimarron Plutonium Plant Manager. The review was examined and found to be critical of the licensee's nuclear materials control system in many of the same afeas in which the system has been criticized by AEC. Some of'the shortcomings noted were the lack of sampling limits of error, the inadequate frequency with bhich reference standards are analyzed in the laboratory, and the obvious impossibility of meeting the 1.5 kg. LDIUF reiguirement. The review is considered satisfactory. . ,,

Compliance with the requirement for estimating anticipated losses for periods between inventories was not investigated during the inspection.

There were no apparent losses of discrete items during the inspection period.

Problem:

I SIGNIFICANT MATERIAL UNACCOUNTED FOR (HUF) QUANTITY This is to supplement the notification of March 6, 1974, regarding the February plutonium materihl unaccounted for loss quantity o 1.5 ograms of plutonium at Kerr-McGee. -

During the period from March 1 through 11, 1974, the licens'ee conducted

, a new inventory. This inventory, which involved an extensive cleanout i-of process equipment and a reevaluation of previous measurements, accounted for 0.1 kilograms of plutonium reducing the February material unaccounted for t . 4, ilograms.

Since the start of , reporting of material unaccounted for quantit es in August 1973, the cumulative material unaccounted for kilograms of plutonium out of. a total system throughput 400 kilograms.

' This unaccounted for plutonium in not considered significant for the operation involved and is believed to be in the process piping systems. There is no indication of theft or diversion.

ERR-McGEE NUC EAR CORPORATION N \ LICENSE SNM-1174 h e%9 N, -

/ 0' In reply to he apparent violation cited in the inspection report enclosed with the February 19 letter from Mr. James M. Keppler, the following written statement and explanation answer the require-ment of 10 CFR 2.201. . '!

The citation quotes erroneously that the LE (MUFH) which according to our license was to be determined and reported as of June 30, for exceeding the limit of 1.5 kgs. specified in the license for LE (MUF). Th E (MUF) e,xpe

  • need by the Plutonium Plant has varied from.O grams to' 0 rams during the same period. While we point out this as an a aly in your citation, we nevertheless recognize this as a
  • serious situation.

The determination of holdup and the related LE was extensively discussed with the Directorate of L1 censing in 1973 prior to the establishment of MPP-1. Our experience in the interin has con-t'inued to demonstrate the difficulty cf close control of these values in the continuous inventory-dominated process in use in the Cimarron Facility.

In recognition of this situation, the following steps are in progress to better . control the holdup quantity in. its variability.

1. Safeguards clerks have been added to the staff to achieve positive control and recording of material m,ovements as of March,11, 1974.
2. The primary source of this difficulty as noted by your inspector has been the assay and the quantities of dilute e

pk ge ca., le. <elease. -

scrap solutions awaiting recovery in the s.olvent extraction cy cl e .

I We aree currently investigating alternate assay procedures employed by other laboratories to improve our analytical precision.

The incorporation of improved methods will not occur before May 1,1974.

I Demonstration of full compliance with this license may require up to six months to determine the effec'tiveness of the changes described above.

In our proposed material control plan submitted March 5 to the Directorate of Licensing, copy to your Mr. Jack Hynd, describes alternate license provisions and the justification more complete'ly.
