2.
30703 - Exit Interview I
The inspectors met with the licensee representatives (denoted in paragraph
- 1) at the conclusion of the inspection on September 10, 1982. The inspectors summarized the scope and findings of the inspection.
3.
92713 - Independent inspection Effort No violations were identified.
The inspection results were attained through a tour of the facility and observation of the licensee's adherence to the Fundamental Nuclear Material Centrol Plan, material control procedures, and their health and safety procedures within the material access area and the reactor area.
j The inspectors noted that personnel contamination monitors were operating and being used by employees upon exiting from the processing. area.
1 The licensee has been investigating a new process in the plating of l
uranium on the target tubes. Presently, the electroplating is from a l
uranyl nitrate solution.
The new procedure is to electroplate from a 002
- slurry, t
l A demonstration of this new process was shown to the inspectors.
I Sampling and measurement points were established to ensure accountability of the uranium.
l 4.
85206 - Measurement and Statistical Controls l
l No violations were identified.
The licensee analyzed the uranium content of standards that were prepared with normal uranium and certified by the New Brunswick Laboratory. One analyst, using the Gravimetric Davies and Gray titration procedure, performed the analyses.
The concentrations of the standards were within a
the licensee's normal operational range.
9006050199 900330 P
3 The three uranyl nitrate standard solutions were as follows:
- M = 0.004983g U/ml
- N = 0.007111g U/ml
- P = 0.0089899 U/ml l
The relative bias for the three standards was significant at the two-sigma confidence level, -0.23% 10.15%.
The control charts, for August and September reflected this negative bias.
To correct the bias, the licensee was to control the laboratory temperature.
Presently, the temperature at which the licensee's standard solutions were made and certified was 8 degrees warmer than the laboratory temp-erature where the analyses of the solutions were used for the control charts.
5.
85208 - Shipper-Receiver Verifications No violations were identified.
The licensee had e.itablished and maintained. procedures to assure that all Special Nuclear Material (SNM) received was accurately accounted for.
The Site Accountability Officer (SA0) coordinated efforts to ensure that license possession limits were not exceeded.
All receipts of SNM were confirmed within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, through examination of source documentation and weight verification. Usually within 5 working days, measurement of the uranium content was confirmed. The licensee had seven receipts and two shipments of SNM since April 27, 1982, and had not experienced any significant shipper / receiver differences (S/Rs) on this material.
Receipts involve only small quantities of uranium (average of 680 grams per receipt).
The NRC Form 741 forms completed for these transactions were reviewed against criteria for preparing and completing the form, timeliness of issuance and completion, correctness of data, and authorized signature.
No discrepancies were noted.
6.
85210 - Internal Control No violations were noted.
The licensee had established and was maintaining a system of written material control and accounting procedures that provided for knowledge of the quantity, identity, and location of SNM within the facility, in accordance with the licensee's Fundamental Nuclear Material Control Plan (FNMCP) and applicable license conditions.
The controls included the master log, subsidiary logs for each material balance area (MBA), and supporting internal transfer documents for transfers between MBAs. The
Q.'.'
4 licensee was in the process of revising certain sections of the FNMCP to reflect current practices.
7.
85216 - Records and Reports No violations were identified.
The inspection results were attained through an audit of the licensee's records and reports for the high enriched uranium physical inventory material balance period of April 27 - June 23,1982. All line items on the SNM inventory report were traced to source documents and cross-checked to the records maintained by the licensee and to the DOE-NMMSS computer tabulations. No discrepancies were noted.
