VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNITS 1 AND 2 NORTH ANNA POWER STATION UNITS 1 AND 2 NRC CONFIRMATORY MEASUREMENTS PROGRAM RESULTS OF SPIKED SAMPLES ANALYSES As indicated in your letter of June 13, 1989, liquid samples spiked with radionuclides were* received at our Surry Power Station on July 19, 1989, and at our North Anna Power Station on July 17, 1989. All analyses were completed by September 12, 1989, that is, no later than 60 days from receipt of the samples.

The liquid samples have been analyzed for tritium (H-3), iron-55 (Fe-55), strontium-89 (Sr-89), and strontium-90 (Sr-90) in accordance with your instructions. The tritium analyses were performed at each station with a liquid scintillation counter, and the Fe-55, Sr-89, and Sr-90 analyses were performed by our vendor, Teledyne Isotopes, Inc.,

as called for by station procedures. The results of our analy~~s are provided in the attachment. . .
