Connecticut Yankee: Turbine Building
Turbine Floor and Paved Area Characterization Survey
December 1997
A survey for beta contamination was performed on 110,000 square feet of paved exterior areas and various floors of the turbine building at Connecticut Yankee Power Plant. The survey consisted of more than 4,000,000 measurements. Satisfactory performance was achieved despite the fact that the exterior surveys were performed under sub-freezing winter conditions. Detection limits of 1000 dpm/100cm2 were achieved at production rates of up to 500 square meters per hour by operation of the SCM at higher survey speeds. Seven previously unidentified discrete radioactive particles were found that exceeded the customer's survey reporting limits.
