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.

1. Key Persons Contacted

i

• E. Harrell, Station Manager

• J. Downs, Superintendent, Administrative Services I

• L. Hartz, Engineering Supervisor

• T. Johnson, Quality Supervisor

• R. Bengquist, Instrumentation Supervisor

• T. Wiseman, Stores Supervisor

• E. Hendrixson, Reactor Engineer i

• J. Leberstein, Engineer i

NRC Resident Inspector

• J. Caldwell, NRC Resident Inspector

The inspector also interviewed several other licensee employees.

• Denotes those present at the exit interview.

2. Exit Interview I

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 l

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.

a. 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).
