Inspection on January 31-February 2,1979 (Combined Recort Nos. 50-289/79-02; 50-320/79-03)
Areas Insoected:
Routine, unannounced material control and accounting inspection including review of facility organization and operation; measurement and controls; shipping and receiving; storage and internal control; physical inventory; records and reports; and management of material control system.
In these areas, the in-spection involved a total of 44 man-hours onsite by three NRC regional based in-spectors.
In addition, a total of 4 man-hours onsite was spent reviewing an em-ployee concern in the area of contamination control in personal dosimetry.
Results:
Of the eight areas inspected, no apparent items of noncompliance were found.

2.
Facility Organization and Operation The licensee has established an organizational structure responsive to nuclear material control and accounting requirements.
The overall custody of special nuclear material (SNM) and management of the nuclear material control and accountability program is the responsibility of the Unit Superintendent. A sufficient number of Item Control Areas (ICAs) have been established for the physical and administrative con-trol of special nuclear material.
A walk-through inspection of the facility was conducted.
As a result of this inspection it was determined that the possession and use of SNM have been confined to the locations and purposes authorized in the license. All operations involving SNM within an ICA are the responsibility of a single individual, a nuclear engineer.
The nuclear material activity for the period covered by this inspection is shown in Exhibits I, II, III and IV of this report.
No items of noncompliance were identified.
3.
Measurement and Controls The inspector verified that the licensee has a method of computing thermal output, uraniam and uranium-235 depletion, and plutonium pro-duction.
Isotopic burnup and production data are calculated using an onsite computer and the Babcock and Wilcox program designated " ATOMS".
The computer monitors plant parameters such as flow, temperatures and pressures.
These data are used in the ATOMS program tc develop core exposures which are then translated into depletion and production re-sults.
13 W3
An NRC independent determination of the uranium-235 depletion and plutonium production agrees with the licensee's reported figures as shown on their Material Status Report submitted for the period June 30,1976 to September 30, 1978.
No items of noncompliance were identified.
4.
Shipoing and Receivino The licensee has established and maintains procedures to assure that all special nuclear material shipped or received is accurately ac-counted for.
A review was perfomed of all Forms NRC-741 generated during the period covered by the inspection to determine proper signature, timely dis-patch and accuracy of data (See Paragraph 7).
No items of noncompliance were identified.
5.
Storage and Internal Control The licensee has established a system of storage and internal control of SNM which provides current knowledge of the quantity, identity and location of all SNM within the facility.
Inventory records are maintained at the site.
Identity and location records include tag boards and grid maps of the reactor cores, spent fuel pools and new fuel storage areas.
In addition to the above records, fuel element history cards are used to maintain item control and provide SNM content of each assembly.
The inspectors selected 100 fuel assemblies at random and tracked their movement within the facility by the history cards and compared the lo-cations listed on the cards with the physical inventory records and tag boards.
No discrepancies were noted.
No items of noncompliance were identified.
6.
Inventory The licensee has conducted physical inventories as required by 10 CFR 70. 51 (d ).
The licensee's last physical inventory for Unit I was April 10, 1978 and for Unit 2 was February 15, 1978.
The licensee's inven-tory consists of a piece count by ICA of all items containing SNM. Core 13'974
.
loading charts are used to inventory the cores.
The new and spent fuel area charts are used as an inventory list which is verified to actual storage locations.
The inventory consisted of:
1.
Unit 1 Assemblies Core -
177 New Fuel Storage -
Spent Fuel Pool -
207 Total Unit 1 -
408 2.
Unit 2 Core -
177 Total Unit 2 -
177 Because of maintenance activity in the Unit I spent fuel /new fuel area,a verification of the inventory was not performed.
No items of noncompliance were identified.
7.
Records and Reports A 100% audit of the Material Transaction Reports (Form NRC-741) genera-ted during the period June 30, 1976 to September 30, 1978 was performed.
The documents were reviewed for completeness, accuracy, signature and timely dispatch.
Material Status Reports (Form NRC-742) submitted during this period were also reviewed for proper signature, timely submissica and accuracy of data.
No items of noncompliance were identified.
8.
Management of Material Control System The licensee has established, naintained and follows a management system which provides for the development, revision and implementation of nuclear material control and accounting procedures.
The licensee's QA section performs an annual audit of the material control and accountability system.
The results of these audits were reviewed by the inspector.
No items of noncompliance were identified.

9.
Contamination Control During the course of the inspection, an employee of the licensee reported to the inspectors that he had received personal dosimeters that were contaminated.
The inspectors contacted the Radiation Protection Supervisor and reviewed the licensee's procedures for contamination control.
The licensee stated that each employee is routinely instructed on how and what to monitor upon exiting the contamination zone, and that personal dosimetry is included as one of the items an employee is supposed to check.
However, there exists the possibility that contaminated thermoluminescent dosimeters (TLDs)
may leave the contamination zone undetected.
This could occur if the employee does not monitor his TLD, places it in the storage area and health / safety personnel collect the TLDs for routine processing.
The badges are collected and placed into a bag, then the whole bag is monitored for contamination.
In this process it is possible for a contaminated badge (s) to go undetected.
The TLDs are routinely processed in the health physics trailer outside the contamination zone.
It was noted that this trailer is not routinely surveyed for surface contamination, but because of the possibility of uncontrolled spread of contamination, the licensee committed to per-form a monthly survey of the area.
No items of noncompliance were identified.
10.
Exit Interview The inspectors met with the licensee representatives (denoted in para-graph 1) at the completion of the inspection on February 2, 1979.
The scope and findings of the inspection were summarized by the inspectors.
