Project: Characterization of On-Site Retention Pond and Spoils Pile at the Point Beach Nuclear Plant

Performance Period: 2000, 2002

Description:

An on-site retention pond was identified as contaminated with low levels of plant-related radioactive materials. ChesNuc applied MARSSIM techniques for resolving regulatory concerns at an operating facility. ChesNuc performed a characterization study to establish the depth and extent of the levels of radioactive material contamination both in the pond and surrounding environs. ChesNuc planned and executed the sampling of the pond for determining its radionuclide profile. A field survey was conducted of the surrounding environment. Gamma scans were used for identifying elevated areas; MCNP modeling was used for correlating a 2X2 inch NaI detector response to 137Cs levels; systematic sampling was used for model verification. An assessment of radiological hazards, remediation activities, and regulatory compliance was completed.
