MILLSTONE LICENSEE MATERIAL IN WATERFORD LANDFILL BACKGROUND INFORMATION: During the week of Decernber 1,1997, Millstone Station sent sediment material from the Millstone Unit 3 Intake cleaning project to the Waterford Landfill on Miner Avenue in Watedord, CT. Evaluations of this sediment material performed by Millstone Station personnel after it's transfer to the landfillindicated the potential for trace amounts of licensee material to be dispos,ed of at the town landfill, On December 4,1997 Millstone personnel, accompanied by the vendor waste hauling contractor (Wayne Coleman, Tinnerallo Hauling Company), went to the area in the landfill where the Millstone Unit 3 sediment materialwas deposited. The town landfill personnel had segregated this sediment materialin an undisturbed manner such that further surveying of this material could be undertaken. Three (3) sediment samples were taken at the landfill on December 4 and returned to Millstone Station for analysis. The results of these three samples showed no licensee radioactivity was present (i.e. samples showed only natural background activity). On December 5,1997 Millstone Station health physics personnel and an NRC representative (Beth Korona) went to the Waterford landfill to take additional samples. Millstone Station and NRC personnel took three additional sediment samples. The rtmple volumes at each of the 3 sample locations were equally divided (split) between the NRC and Millstone such that the NRC and Millstone could count these materials in - their independent laboratories to compare results. Tr,e rasults of both the NRC independent analysis and the Millstone analysis again indicated that this material was free of licansee radioactivity (i.e. samples showed only natural background activity.) 1

h Also on December 5,1997, a few hours after the NRC sample acquisitien at the Waterford landfill, the State of Connecticut Department of Radiological Protection sent a State survey team to take additional samples for analysis by the State of CT. State representatives, accompanied by a Millstone Station representative, took three sediment samples and sent them to Teledyne Lab in New Jersey for analysis. On Decerr)ber 15,1997 the State of CT mada formal confirmatica to Millstone Station that the results of their vendor lab counting analysis indicated that two of the three samples of the landfillindicated trace amounts oflicensee material were present. The third sample indicated normal background activity. The two positive results from the State indicated trace amounts of cobait-60 to be: 6.17 E-02 (+- 3.01) pCilgm and 7.70 E-02 (+-2.95) pCi/gm oobalt 60. On December 18,1997 Millstone Station management notified the Town of Waterford that Millstone would remove the Unit 3 sediment material from the landfill and return it to Millstone Station. On December 19,1997 Millstone Station removed all Millstone 3 sediment material previously segregated by the Landfill authority. This material, measuring approximately 70 r ubic yards, was returned to Millstone Station on the same day. Concurrent with the removal of the Unit 3 sediment material, Millstone personnel took 8 sediment samples at the landfill to determine if any additional material still remained in place at the landfill. The results of these 8 sediment samples, also analyzed on December 19, indicated that the landfill was free of licensee related activity (all samples showed normal expected background). On December 24,1997 the State of CT took a series of confirmatory sediment samples at the Waterford landfill to verify and document that the landfill was properly remediated by the removal of the Millstone 3 sediment material. The results of the State of CT re-sampling at the Waterford Landfill will be released by State officials at a later date. l t l (

i Statistics: Using exoosure codes, the 0.06 pCl/gms cobalt -60 at the Waterford landfill equal: A. If you stood motionless over this dirt for 365 days 24 hours per day you would receive less than imillirem (in CT you receive approximately 1 millirem per day from terestrial radiation and radon). B. If you ate 1,600 pounds of this material you would receive 1 mrem. Standard man consumes 1200 pounds of food per year. Thus this is over 15 months of consumption of nothing but dirt. I C. If you ate 6,400 pounds of this dirt (3.2 tons, or the equivalent of 5.3 years of food consumption of nothing but dirt) you would equal the exposure of a round trip plane flight to California. e _ _ _ _ _ _ - _ _ - _ _ _ _.}}
