2. -Licensee Action on Previous Inspection Findings (0 pen) Unrasolved Item (80-02-03): Calibration range for point calibration needs to be defined. Pending evaluation in conjunction with NRC correspondence.

i (0 pen) Unresolved Item (80-07-02): Need to define what constitutes inside the range for point calibration. Pending evaluation in conjunction with NRC correspondence.

(0 pen) Unresolved Item (82-07-01) Need to revise FNMC Plan to reflect the current practice to responding to out-of-control limits. Pending evaluation ia conjunction with NRC correspondence.

(Closed) Violation (53-05-02): Failure to verify each assigned value for the reference standards used for ICPAES for determining Uranium P3h in liquids. The licensee has revised Calibration and Operation Inst.uction No.17 to include the verification for each assigned value. The current values for ICAPES standards have been verified in this manner.

l I (Closed) Inspector Follow-up Item (83-11-01): Samples taken to verify the acceptability of the licensee's measurements. A review of the data did not reveal a discernable difference between New Brunswick Laboratory and the licensee's values for the samples.

(Closed) Inspector Follow-up Item (81-15-01): Samples taken to verify the acceptability of the licensee's measurements for an overseas shipment. A review of the data did not reveal a discernable difference between New Brunswick Laboratory and the licensee's values for the samples.

(Closed) Inspector Follow-up Item (83-20-01): Samples 'taken to verify the acceptability of the licensee's measurements for an overseas shipment. A review of the data did not reveal a discernable difference between New Brunswick Laboratory and the licensee's values for the samples.

3. MC 85200C - Measurement and Statistical Control The program for monitoring and controlling the performance of standard measurements used for accountability purpose was examined. The analytical methods for uranium have limits determined by statistical techniques and are based upon the historical performance of the method. Each measurement system ha:: a warning limit and an out-of-control limit that are reevaluated at least once each material balance period. The measurement method, the frequency of out-of-control situations, the periods examined, and the number of standard measurements performed are presented in Table I. In following-up on the control chart data for total metallic impuritics (TMI) it was found that the licensee had experienced some temporary difficulties when perfonning this measurement as a result of having had to change the brand of graphite electrode normally used. A suitable alternate c.upplier was found correcting this situation.

The licensee has begun the production of U02 pellets for the Babcock and Wilcox (B&W) loledo Edison contract. /

They will then be shipped to Babcock and Wilcox Comercial !

NuclearTJEl Division in Lynchburg, Virginia.

Holdup data were examined for the August 1983 physical inventory. It was determined that the only holdup on inventory was that contained in the HEPA filters. The uranium content assigned to the HEPA filters are detennined by one of three methods: (a) actual filter weighings, (b) calculations based on actual weight gain over a time basis, and (c) a sampling program.

The sampling program was added to the 1983 inventory activities to assign holdup values to the secondary HEPA filters in FM0 an ! FM0X. The program consisted of removing and elephant gun scanning two filters from each of eight representative secondary filter banks. The average value of the l results was.then assigned to all secondary HEPA filters.

The licensee's housekeeping in this area was found to be satisfactory. The ,

stack sampling program as delineated in Procedure EPI No. 0-6.0, Revision 4 was reviewed in detail with respect to sample analysis and handling of data. The results of this review were also found to be satisfactory.
