Docket No. 50-245 50-336 50-423 B16973, Attachment 1 Millstone Nuclear Power Station, Unit Nos.1,2, and 3 Summary of Balifield Survey Results

/

January 1998

G r

l January 13,1998 Mr. White:

Hopefully this ;nformacion is of use to you.

I have attached a numbering scheme (starting with 1.) as to the way you may want to read this. Number 1 starts with a macroscoole (summary type) overview, whereas the individual thicker reports are more detailed as they contain individual multi-channel analyzer printouts. I have over 1000 additional pages of multichannel analyzer printouts from the balifields in Waterford, CT. that I have not colleted in a booklet foremat or sent to you at this time. The results of each balifield is in a separate 4" thick- 3 ring binder that is -

available after a reproduction effort, if desired.

Our intention is to keep an active interface with the NRC, the State of CT, the Town of Waterford, and concemed citizens on this issue.

Please feel free to call me at work at (860) 440-0475 if you need additionalinformation.

Sedimerit LLD's Based upon the attached spreadsheet, the LLD's for landfill samples is approximately 3.5 E 8 uCilgm for Cs 137 and Co-60. This is based upon the actual counts and thorough review of the data by technical reviewers (Hank Siegrist and I). The review provides better assurancu that the count data is correct and actually identifies activity below the LLD's on the spreadsheet.

These LLD's are approximately 2.5 to 3 times than that orginally predicted (those based upon the 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> background counts). This is due to higher background from the uranium and thorium daughters and the use of the 2.71 factor recommended in NUREGICR 4007 (although not included in the NUREG's 1301 and 1302 formulas). Because we are counting wet welght, the above LLD's would assure that we met the LLD's referenced in NUREG's 1301 and 1302.

Millstone Station Soll Samples in the Town of Waterford, Connecticut For your information please find the enclosed reports of soll sample analysis per-formed during 1996 and 1997 by Millstone Station on recreational ball fields, State Park facilities, and Town Landfill areas located . Waterford, Connecticut.

BALL FIELDS:

During December 1996 and October 1997 Millstone Station perfonned a series of soil sample ant. lysis, and direct radiation measurenients, on six (6) recreational ball fields ,nd dirt mound area located in Waterford, CT. The six ball fields and dirt mour.1 area are identified as (figure 1):

cials written in 1996 and 1997 indicating that a potential existed for contamination of these ball fields from soil donations from Millstone Station to the Town of Waterford, CT.

0 These six ball fields and dirt mound area are located in a recreational park complex bounded by Rope Ferry Road and Gardiners Wood Road on the east portion of Millstone Station owner controlled property as shown on the attached aerial presenta-tion (figure 2). This recreational park complex is situated on Northeast Utilities owner controlled property, which is granted to the Town of Waterford for public use, under a revocable license agreement bermen Northeast Utilities and the Town of Waterford, CT.

Babe Ruth Field Spera Soccer Field Greco Football Field Dirt Mound The results of these surveys indicate that these recreational fields are free of radioac-tive materials frme Millstone Station related activities. These six recreational fields have radiation levels similar to other locations in Connecticut consistent with natur-al background levels found in New England.

1 1  ;

Copies of these surveys were delivered to Kevin McCarthy, State of Cont ecticut Department of Radiological Protection, in Hartford, CT on November 14,1997.

i Additionally the results of these surveys have been transmitted to Mr. Tony

, Sheridan, First Selectman Town of Waterford, CT, Additionally, on October 29,1997,

Millstone Station Health Physics personnel presented the results of these surveys to the general public in an NRC sponsored restart presentation chaired by Wayne Lanning, USNRC. At the completion of the October 29,1997 NRC sponsored town meeting, two - 4' by 3' laminated colored aerial presentations of the ball field sur-veyed area, and a Millstone Environmental Program map was left at Waterford j . Town Hall for information purposes for public use.

! HARKNESS STATE PARK EQUESTRIAN CENTER I In November 1997 Millstone Station performed a series of soll sample analysis, and direct radiation measuremen'.s, on the Harkness State Park Equestrian riding center located in Waterford, CT (figure 3). The Harkness State Park Equestrian Center is a 17,600 square fo$ t outdoor riding arena designed to provide riding experiences for handicap children from the State of CT. This facility received donated soil materials from Millstone Station in the early 1980's for landscape and grading improvements.

This area was surveyed upon the request of Town of Waterford officials in response to contamination results from areas surrounding the Connecticut Yankee facility in East Haddam, CT.

This facility has radiation levels similar to other locations in Connecticut consistent with natural background levels found in New England.

A report of the Harkness State Park radiation analysis was forwarded on December 24,1997 to the management staff of the Harkness facility. Additional copies are being prepared for distribution to the State of CT Department of Radiological Protection and the Town of Waterford First Sclectman office.

TOWN LANDFILL WATERFORD, CT.

In December 1997 Millstone Station performed a series of radiation measurements 3 and soll analysis of the Town Landfill in Waterford, CT (figure 4). The Waterford Town Landfill is a 15 acre site located at Miner Lane in Waterford, CT.

These surveys were taken as a confirmatory measure to ascertain the radiological status of he Waterford I.andfill facility after material was transported and dumped at the landfill from Millstone Unit 3 intake structure cleaning activities. This action was undertaken when it was discovered that silt / sludge and sea shell material removed from the Millstone 3 intake structure had potentially contained a trace amount of licensee 4adioactivity.

I Surveys were taken in the approximate 30' by 60 ' area of the landfill which was used as the deposit area for the Millstone 3 intake material. A total of 12 silt / sludge samples were taken at the Waterford 1.andfill at the location of the Unit 3 intake material deposit during December 4 and 5,1997. Millstone Station took 3 silt / sludge samples, the NRC took 3 samples, and the State of CT took 3 samples. The results of the Millstone and NRC sampling indicated the Town Landfill was free of contami-nation using an environmental lower level of detection (1.LD) counting methodolo-

! gy. Ihe State of CT counting of these samples was completed on December 12,1997.

The State of CT results indicated one sample as free of radioactivity, and two sam-ples were reported to contain 0.07 and 0.06 pCi/gm of licensee related activity (Co-60 only isotope detected). ,

On December 18,1997 Millstone Station management personnel notified Tony Sheridan, Tcwn of Waterford First Selectman, that Millstone Station had elected to remove the Millstone 3 I silt / sludge material (figure

5) from the town landfill. On December 19,1997, Millstone Station removed approximately 60 70 cubic yards of material from the Waterford landfill and N. ' returned the material back j  ? to the Millstone facility.

STATE OF CONNECTICUT SURVEY PROGRAM:

On December 23,1997 the State of CT performed independent backup soil surveys of the Town of Waterford landfill area and the Harkness State Park Equestrian Center. Surveys by tl e State of CT are under the direction of Kevin McCarthy, State of CT Department of Radiological Protection (860-424-3029).

The State of CT has indicated it may elect to perform backup soil surveys of the Waterford recreational complex (ball fields as described in above paragraphs)in the future. Millstone station is staying in co: et with the State of CT to obtain results of these surveys as they become known.
