SUMMARY
Scope: This routine, announced inspection was conducted by one NRC inspector
in the areas of nuclear material control and accounting procedures, records and
reports, and physical inventory.
Results:
One violation was identified for failure to establish and maintain
an adequate material control and accounting procedure which resulted in a
failure to conduct an annual physical inventory of all special nuclear
material.

Exit Interview
The inspection scope and findings were summarized on May 21, 1987, with
those persons indicated in paragraph 1 above.
The violation relating to
failure to establish and maintain an adequate material control and
accounting procedure which resulted in a failure to conduct an annual
physical inventory of all special nuclear material (SNM) (paragraph 3) was
I
discussed in detail.
The licensee acknowledged the inspection findings
and stated that all incore detectors were onsite'.
3.
Material Control and Accounting - Power Reactors (85102)
The inspection was conducted to determine the adequacy of Virginia
Electric and Power Company's program to account for and control the SNM in
its possession and to limit the use of possessed SNM to the locations and
purposes authorized by licensee at the North Anna Nuclear Power Station.
The licensee's material controls were examined by review of procedures,
audit of records and reports, review of the conduct of physical inventory
and interviews with appropriate licensee personnel.

Procedures Review
The inspector reviewed the procedures and documents listed below:
(1) DOE /NRC - 741 - Nuclear Material Transaction Report
(2) 00E/NRC - 742 - Material Balance. Report
'
(3) DOE /NRC - 742C - Physical Inventory Listing-
(4) Fuel Assembly History Sheets
(5) Incore Device History Sheets
(6) Fuel Assembly'and Insert Component Accountability and Control
Audit Procedure No.
FQAI 18.10, Rev. 0, dated January 27,/1986.
.(7) Nuclear Material Control Procedure No. ADM - 19.24, dated May 29,_
1986'
~
(8) Virginia Nuclear Fuel Handling Report
VNF-7
(9) Fuel Assembly Inventory Records
(10) Replacement of Incore Flux. Mapping Detector,. Procedure
No. IMP-C-IC-01,-Rev. 5, dated of 26-82
(11) Core Mapping Following Core Loading Procedure No.1-0P-4.16,
Rev.5, dated March 13, 1987
.
The licensee's Nuclear Material Control Procedure No. ADM-39.24 was-
determined to be inadequate in that it did not address. the.-
fundamental elements of material control in _the < ~ area of storage,
inventory, and internal transfers of SNM incore and excore detectors.
In addition, no written statements of responsibility and authority
for the positions responsible for SNM incore and excore: detectors
receiving, shipping, i r.ventory , sto' rage and ' internal transfers were
addressed in the procedure.
Therefore, failure of, licensee to
establish and maintain a material control and' accounting procedur_e to
sufficient account for all SNM is in L violation of 10 CFR 70.51(c)
(50-338,339/87-09-01) which resulted in an additional violation of
NRC regulatory requirements (see paragraph 3c),
b.
Records and Reports Audit
Receipts and shipments of SNM for the . perio'd' September 30, 1984
through March 31, 1987, were verified by examination ofl DOE /NRC- Form
741s, " Nuclear Material Transaction Report." The transaction reports
had been completed in accordance_with NUREG/BR-0006 instructions. To-
determine the adequacy of the licensee's fuel accountability records,-
a sampling- of several fuel assemblies stored in the; spent fuel'
storage area and reactor cores were traced through internal transfer-
records to Nuclear Material Transaction; Report - 00E/NRC-741, and
compared to a schematic diagram. located in the refueling officeL for
verification of the fuel assembly-identification and location._ The
licensee's_ Material Balance. Reports (Form _ DOE /NRC-742S) werefreviewed
for the period September 30, 1984 through March-21, 1987, to determine
whether . the reports accurate?y reflected quantities of SNM in the -
,
material balance for these periods.
The reports were completed 'in
- 1
accordance .with- NUREG/BR-0007 and recorded data including nuclear
material depletion and production were found to be in_ agreement with
the accountability records for fuel assemblies and inventory L for-
Unit 1 and 2, spent fuel storage _ area, and new-fuel storage: area.

It was determined from the discussion held with the licensee during
the inspection that to date the North Anna Nuclear Power Station has
received 40 incore detectors and four excore detectors. Two incore
detectors were shipped to Surry ' Nuclear Power Station, seven incore
detectors are in stock on QC hold, ten incore detectors are currently
i
in use. Since licensing, twenty-one incore detectors were apparently
transferred to storage tubes.
The inspector determined that the
)
licensee had control documentation and working knowledge of the -
!
movements of incore detectors once they had been removed from the
reactor and stored in tubes.
No vColations or deviations were identified
c.
Physical Inventory
The inspection determined that the licensee has conducted a physical
inventory of the new and spent fuel storage after aach refueling or
at least annually in accordance with the licensee's procedure. The
physical inventory consisted of a 100% piece count in the spent fuel
storage area (SFSA) with a random selection of fuel assemblies in the
SFSA for serial number verification at 95% confidence level.
A
100% serial number verification was also conducted in the new fuel
storage area. A video tape of the reactor cores is being saved as a
record of physical inventory of the reactor cores.
1
The inspector determined that discrcte irradiated incore detectors,
i
containing SNM, had been excluded from the annual physical inventory
listing since the licensee was not aware of such requirements.
Failure of the licensee to conduct an annual physical . inventory of
all SNM incore and excore detectors is in violation of 10 CFR 70.51
(d) (50-338,339/87-09-01).
