UNITED STATES NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT 20555 May 10, 1979 IE Information Notice No. 79-12 ATTEMPTED DAMAGE TO NEW FUEL ASSEMBLIES This Notice provides information concerning the surreptitous introduction of a possibly damaging liquid into the new fuel storage pool at the Virginia Electric and Power Company, Surry Power Station in Surry County, Virginia.
On Monday, May 7,1979, while conducting inspections of new fuel for Unit 2, the licensee found that plastic protective liners on 62 of 64 assemblies had been tampered with.
Further inspection revealed that a white crystalline substance had been poured onto the assemblies.
Preliminary analysis by VEPC0 indicates that the substance is sodium hydroxide.
The new fuel is stored in the Fuel Building, an area which is locked and alarmed, and to which access is controlled by the issuance of specially coded access cards. These cards are issued after the successful completion of a background screening program for both Virginia Electric and Power Company and contractor personnel.
The FBI is presently on-site conducting an extensive investigation.
Westinghouse, the fuel vendor, is assisting in the evaluation of possible fuel damage.
This event could possibly provoke similar behavior on the part of other persons. Consequently, you should be aware of such an eventuality. At this time the NRC is not placing additional requirements on you, but is advising that extra caution be exercised in your 9xisting security program.
This Information Notice is provided as an early notification of a possibly significant matter.
It is expected that recipients will review the information for possible applicability of their facilities.
No specific action or response is requested at this time.
If further NRC evaluations so indicate, an IE Circular or Bulletin will be issued to recommend or request specific licensee actions.
If you have questions regarding the matter, please contact the Director of the appropriate NRC Regional Office.
No written response to this Information Notice is required.
