Independent Inspection Effort The inspectors reviewed and observed implementation of the licensee's access control procedures for visitors to the facility and determined that the licensee complied with the NRC-approved physical security plan.
3.
Facility Organization and Management Controls The inspectors determined through a review of the licensee's material control and accounting (MC&A) procedures, that the licensee is maintaining and following a management system that provides for the development, revision, implementation and enforcement of MC&A procedures. The system provides for written approval of MC&A procedures and any revisions to those procedures by the individual with overall MC&A responsibility and by plant management.
Records of training were reviewed that indicated implementation of the licensee's Fundainental Nuclear Material Control Plan (FNMCP) commitments to have staff members and SNM custodians, assigned to material concrol and accounting functions, receive training that is commensurate with job responsibilities.
4.
Measurement Systems Nine standa.rds with varying matrices and concentrations of uranium were provided to the licensee for analyses by the NRC inspector. The liquid standards were prepared with normal uranium and certified by New Brunswick Laboratory (NBL). The uranium concentrations and matrices were within the i
normal range of the material the licensee routinely analyses.

The inspector observed a technician analyze three of the standards using l
the spectrophotometric TOP 0 extraction procedure.
This procedure is used l
to analyze low level uranium concentrations found in laboratory waste solutions.
Except for the lowest concentration, the analyses of the NRC uranium standard solutions compared well, with good precision. The source of error for the lowest concentration standard was the large dilution that was made (2ml diluted to 1000ml).
The results are indicat^d in the l
following table:
NRC Standard Relative % Bias Uncertainty

+2.9 2.4
.0000057g U/g
+2.6 7.0
.0000011g U/g
+54.6 26.5 l
The inspector observed another technician analyze three NRC standards representing unfinished fuel, using the gravimetric Davies and Gray titration methd. The analyses of the NRC standard solutions compared well, with good precision.
The results are indicated in the following l
table:
NRC Standard Relative % Bias Uncertainty
- 0.0146819 U/g
-0.05 t0.07 l
0.020029g U/g
+0.04 0.13 0.025461g U/g
-0.03 0.02 The inspector also observed two technicians analyze the remaining three NRC standards, representing finished fuel, using the gravimetric Davies l
and Gray titration method.
During NRC Inspection No. 86-13, the analyses l
of these NRC standards identified a positive bias which was attributed to a low room temperature (20 C).
Since then, the licensee has recorded the i
room temperature which showed a fluctuation f rom 20 C to 27 C.
The plant l
was recently air conditioned and this improved the temperature and humidity I
control in the laboratory. Management will now concentrate on limiting l
temperature fluctuations in specific areas of the laboratory to 2 C.
l When the technicians analyzed these standards during this inspection, the temperature in the laboratory was more stable.
However, significant bias still resulted because of the temperature fluctuations.
The results, for each techinician, are indicated in the following table:

Records and Reports The inspectors audited the nuclear material control records and reports for the material balance periods ending March 13, 1987, May 15, 1987, and July 17, 1987. All line items on the SNM inventory reports for the three material balance periods were traced to source documents and compared to the records maintained by the licensee and to the DOE-NMMSS computer j
tabulations. The licensee's general ledger was also checked for accuracy.
Nuclear Material Transaction Reports (DOE /NRC Form-741), which documented receipts, shipments, measured discards, and inventory changes, were reviewed for timelir.ess, format, and accuracy of content.
No discrepancies were found.
Material Status Reports (DOE /NRC Form-742), submitted for the material balance period ending March 31, 1987, were also reviewed for the same attributes.
No discrepancies were identified.
The inspectors determined that the licensee's control and subsidiary records for the periods under review were adjusted to the results of the physical inventories, as required by NRC regulations.
6.
Exit Interview The inspectors met with the licensee representatives indicated in para-raph I at the conclusion of the inspection on September 25, 1987, and summarized the scope and findings of the inspection.
At no time during this inspection was written material provided to the licensee by the inspectors.
