                The purpose of this specialinspection on July 16,1997, was to accompany
                Connecticut Yankee (CYAPCo) staff and to observe a radiation and soil
                contamination survey at a private residence on Injun Hollow Road in Haddum Neck,
                Ct.- A representative from the State of Connecticut Department of Environmental
                Protection was also in attendance to observe the licensee's survey and to conduct
                independent measurements. The NRC and the State of Connecticut obtained split            t
                soil samples for independent analysis.

1              A Haddam Neck property owner received from the plant general land fill during a
                plant construction project in the 1980s and more recently, top soil in the Fall of
                1996. The fill was excavated from the site when CYAPCo renovated a parking lot
                on the north side of the plant site. The parking lot was outside the protected and
                radiological controlled area. Accordag to CYAPCo personnel, when the parking lot
                was expanded, several islands were removed and a machine was used to break
                down the asphalt and mix it with the excavated gravel and other parking lot
      l
                construction materisis. Most of the excavated materials were taken by truck to a
                plant landfill area on the south side of the site. A plant engineer estimated that
                about 2 truck loads were delivered to the property owner 6t his request. Following
                recent media reports of site contamination at the Haddam Site, the property owner
                contacted the licensee to request assistance in a radiological assessment of the fill    r
                at his property.                                                                          '
                Survey Plan
                The licensee planned a survey of the property using three techniques. Very
                sensitive gamma survey instruments were used to provide a radiation scan over a
                wide area of the property. The gamma surveys were taken over areas where the
                property was known to contain fill from the plant, as well as in areas known to
                contain only original material from the property. The gamma surveys were
                supplemented with scans by a gamma spectroscopy instrurrent that could
                differentiate between naturally occurring radioisotopes and those resulting from
                power plant operations, notably Cs-134, Cs-137 and Co-60. The gamma
                spectroscopy measurements were taken at an area known to not contain plant
                related material; this measurement was used to obtain a " background
                measurement". Additional gamma spectroscopy measurements were obtained on
                areas of interest as indicated by the gamma survey measurements. The licensee
                took soil samples using a similar approach: a background soil sample was taken
