2.
Licensee Action on Previous Insoection Findinas There were no items of noncompliance noted on the previous Material Control and Accounting inspection (Report 50-20/78-04 et al).
3.
Exit Interview The inspector met with licensee representatives (denoted in Paragraph 1) at the conclusion of the inspection on flovember 15, 1979.
The inspector summarized the scope and findings of the inspection.
4.
Unresolved Items There were no unresolved items noted on the inspection.
5.
MC 92706B - Independent Insoection Effort fio items of noncompliance were noted.
The inspection results were attained by direct observations, discussions with licensee personnel and review of records.
The inspectors, as part of the walk-through inspection, requested radiation readings be taken in several areas to insure posted radiological signs were in compliance with applicable regulations.
fio exceptions were noted.
Leak test records for sealed sources were reviewed for completeness and timeliness.
flo exceptions were note.
MC 85102J - Material Control and Accounting a.
Facility Organization and Ooeration No items of noncompliance noted.
The inspection results were attained through review of various procedures and discussions with licensee personnel.
The inspectors review of the licensee's written procedures included
" Manual of Procedures and Instructions Related to Accountability for Source, Special Nuclear and Certain Other Materials," Revision 9-78.
During the previous material control and accounting inspection the licensee agreed to revise these procedures.
The most current revision at that time was Revision 6-71.
Specific changes that were to be included in these procedures were:
(1) Revision of the organization chart to reflect organization changes made on July 1,1976.
(2) Removal of references to the " Atomic Energy Commission."
(3)
Separations of functions to provide a system of checks and balances.
The inspector's review of the procedure disclosed the above changes ware included in Revision 9-78.
The licensee is authorized to possess and use special nuclear material (SNM) in the operation of the reactor and in teaching and research in campus laboratories, at the Lincoln Laboratory in Lexington, Massachu-setts, and at the William H. Bates Linear Accelerator Laboratory at Middleten, Massachusetts.
b.
Shipping and Receivino No items of noncompliance were noted.
Inspection results were attained through review of each of the prepared Forms NRC-741, Nuclear Material Transaction Reports, against criteria for completing the form, timeliness in issuance and completion, correctness of the coding information, and evidence of significant shipper-receiver differences.
During the period April 1,1978 through September 30, 1979, there were three receipts from Oak Ridge, Tennessee.
No discrepancies were identifie.
c.
Physical Inventory No items of noncompliance were noted.
The inspection results were attained through review of procedures, discussions with licensee personnel and verification of physical inventory items not in the reactor.
The presence of Stim ir the form of unirradiated fuel elements, loose plates, fuel rods, pir,, foils, buttons, and scrap was verified by the inspectors.
The PuBe neutron sources on campus and not in the core were also verified.
Ti presence of neutron sources at laboratories in Middleton and Lexing tun, Massachusetts, were not verified.
Review of the licensee's last physical inventory, dated October 31, 1978, disclosed that some icems on the inventory were not actually physically inventoried until flovember and December,1978.
Discussions disclosed that the licensee was uncertain about the required time frame for inventories and reconciliation, and these times were not addressed in internal procedures.
The situation was clarified by the inspectors and the licensee committed to revise internal inventory procedures by January 15, 1980, to include beginning and ending times for the inven-tories and the 30-day completion time for the reconciliation. This item will be reviewed in a subsequent inspection (79-03-01).
d.
Records and Reports No items of noncompliance were noted.
The inspection results were attained through a complete audit of the Material Status Reports (Form NRC-742), covering the period April 1, 1978 through September 30, 1979.
The review covered proper signature, time of submission, and accuracy of data.
During the period covered, the licensee had a normal operational loss of 21 grams U-235 which was incurred in decladding and recladding U02 pellets for reactor physics experiments.
An inven-tory difference gain of 4 grams U-235 was attributed to remeasurement of material in process and to rounding.
The attached Exhibits I-IV present the audited material balance statements for enriched uranium and plutoniu.
