neutron sources.
The authorization to receive, possess, and use these sources is contained in Paragraph 2.c of License Amendment No. 18 to License DPR-16. This amendment was issued by the NRC's Division of Operating Reactors, Office of Nuclear Reactor Regulation, (DOR-0NRR) on December 30, 1976.
A sufficient number of Item Control Areas (ICA's) have been estab-lished by the licensee for the physical and administrative control of SNM.
These areas are referred to as MBA's by the licensee in their procedures.
The licensee's activity for the four matarial status report periods covering July 1,1976 to October 31,19,3 is shown in Exhibits I, II, and III of this report.
The licensee requested a change in the ending date of the last of these four periods, fron September 30 to October 31, 1978.
The licensee received such approval in a letter dated October 29,1978, from D0R-0NRR.
No items of noncompliance were identified.
4.
Measurement and Controls The licensee utilizes a computer program (Xtra) to detennine ex-posure and exposure weighted void array on individual fuel assemblies.
This information is then used as the basis for determing isotopic values from another computer program (ISAG) furnished by the licensee's fuel suppliers, General Electric and Exxon.
Since the last inspec-tion, the licensee has made some changes to the latter program which resulted in changes to the uranium and uranium-235 depletion and plutonium production numbers criculated and reported since startup.
The licensee revised all Material Status Reports since January 1,1975 so as to accurately reflect the activity for those periods.
However, this created an imbalance aetween the report covering the January 1, 1975 to June 30, 1975 and the report for the preceding period.
This is discussed in detail in paragraph 8.
The inspector indcpendently detennined the uranium and urai. fem-235 depletion and plutonium production values for the four material status report periods beginning July 1,1976.
The independent determination is censidered in agreement with the licensee's re-ported values.
A comparison of the licensee's values and the NRC's values is presented in Exhibit I.
The inspector also verified that the licensee is accurately cal-culating and reporting Pu-241 decay.
No items of noncompliance were identified.
5.
Shipping and Receiving
-
The licensee has established and is mafhtaining a.-program to assure that all SNM received or shipped is accurately account for. The program is implemented through the use of shipping and receiving procedures which are contained in the General Plant Operating Pro-cedures, Section 200.
Since the last inspection, the licensee has received fuel assemblies from Exxon on four occasions, and also shipped two assemblies back to Exxon. Additionally, the licensee received the two PuBe sources.
The licensee confirmed all receipts of SNM and promptly reported the receipts to the Technical Engineer. Material Transaction P,e-ports (Fonn NRC-741) were receipted within 10 days and returned to the shipper.
No items of noncompliance were identified.
6.
Storage and Internal Control The licensee has established a system of storage and internal con-trol of SNM which provides for a current knowledge of the quantity, identity and location of all SNM within the facility.
Perpettal inventory records are maintained for the reactor and storage areas showing the identity, SNM content, and location of all items containing SNM. These records consist of the computer print-out, core and fuel pool schematics, SNM card file, SNM cove sheets and MBA Transfer Forms.
The inspector used the above mentioned records and traced the move-ment of approximately 40 assemblies during the last refueling.
No discrepancies were.noted.
No items of noncompliance were identifie.
7.
Inventory The licensee conducts a physical inventory semi-annually, in accord-ance with written inventory procedures.
During an inventory all identifiable items are accounted for. The inventories for CY 1978 were performed on May 5 and November 6,1978.
The licensee's inventory at the time of the inspection, consisted of 560 fuel assemblies in the reactor, 620 irradiated fuel assemblies in the spent fuel pool, 20 unirradiated fuel cssemblies in the spent fuel pool,13 fuel pins contained in 2 casks in the spent fuel pool, and two PuBe courses located on the fourth floor of the reactor building.
The inspector performed an inventory verification which consisted of a piece count of all assemblies in the pool, observation of the two casl:s in the pool which contained the 13 fuel pins, and visual observation of the two PuBe sources. Additionally, the in-spector performed serial number ' verification of 39 fuel assemblies in the pool and found their position to be as stated in the records.
No items of noncompliance were identified.
8.
Records and Reports The inspector reviewed the licensees perpetual inventory records as described in paragraph 6.
No discrepancies were discovered.
In addition, the Material Status Reports (Form NRC-742) and Material Transaction Reports (Form NRC-741) were reviewed.
Review of the Forms NRC-742 revealed that the licensee had revised and resubmitted Material Status Reports for all periods beginning January 1, 1975.
The revisions resulted from discovery of errors in the computer program for determining uranium and uranium-235 depletion, plutonium production and Pu-241 decay, and also from revisions to SNM values of fuel assemblies shipped to NFS in 1975.
The inspector's review, however, indicated that some discrepancies in these forms still existed for some previously submitted Material Status Reports, as described below. The licensee committed to correct and resubmit these forms by January 19, 197 Period Discrepancy July 1,1974 - December 31, 1974 The licensee's revision of the Form NRC-742 for the period January 1,1975 to July 31, 1975 resulted in a change to the Beginning Inventory for that period.
This revised value does not agree with the Ending Inventory value fc-the period ending December 31, 1974.
The difference is a result of the change in the computer code.
The licensee will revise the Form NRC-742 for the period er. ding December 31, 1974 and adjust the Ending Inventory by this difference.
The difference will also be reported as Depletion or Production (with an explanation) to maintain a balance for this period.
January 1,1975 - June 30,1975 The licensee's receipt total on the Form NRC-742 differs frcm the total of all Fonn NRC-741 receipts for the period by (1)
gram U and 3 grams U-235.
These differences are due to rounding.
Since the Form NRC-742. receipt value must be in agreement with the total of all Qnn NRC-741 receipts, the licensee will correct the Fonn NRC-742.
The differences will be entered on the line for MUF with an asterisk explaining that the differences result from rounding.
July 1, 1975 - December 31, 1975 Same as previous period.
Differ-ences were 1 gram U and 1 gram U-23 '
.
The licensee's Form NRC-742 reports for Pu-238 indicate 1 gram plu-tonium and 1 gram Pu-238.
Acutual values are 1.2 gram plutonium and 1.0 grams Pu-238. Since 'ae reporting instructions require reporting to the nearest tent! of a gram when the material is Pu-238, the licensee will reissue all affected NRC-742 Forms to reflect this change.
Since the last inspection, the licensee has had four receipts of fuel from Exxon Nuclear Corporation, and has made one shipment to Exxon.
The Forms NRC-741 for these transactions were reviewed for completeness, accuracy, signature, and timely submission.
No discrepancies were noted.
At the time of the inspection, the licensee was in the p ocess of revising Forms NRC-741 for the 'hipments in 1975 to NFS, West Valley, New York, to reflect changes in the SNM values for the fuel assemblies resulting from changes in the computer program.
Since these changes were already reflected in the revised Material Status Reports submitted November 30, 1978, these Forms NRC-741 should already have been submitted.
The licensee agreed to submit these by January 19, 1978.
Nr items of noncompliance were identified.
9.
p.nagement of Material Control System The licensee has established, maintains and follows a management systa which provides for the development, revision, implementation and enforcement of nuclear material control and accounting procedures.
No items of noncompliance were identified.
10.
Exit Interview The inspector met with licensee representatives (denoted in Para-
'
graph 1) at the conclusion of the inspection on January 11, 1979.
The inspector sumarized the scope and findings of the inspecton.
The licensee indicated that all revised Form NRC-742 and Form NRC-741 reports would be submitted by January 19, 197 Exhibit I Oyster Creek Material Balance Summary July 1, 1976 - November 30, 1978 Enriched Uranium RIS:YHA Grams U
