May 2001 - September 2001
Provided consulting and radiological survey support to the Yankee Power Station in anticipation of the movement of spent fuel and greater then Class C waste to the Independent Spent Fuel Storage Installation (ISFSI). It was recognized by the utility that the storage of this material in the ISFSI would increase background radiation levels at the site and make future surveys for license termination in these areas more difficult. The team developed and submitted recommendations, developed investigation criteria and Survey Plan, performed a survey, and generated a final report.
The survey was performed utilizing two state of the art survey technologies: the Surface Contamination Monitor / Survey Information Management System (SCM/SIMS) and the Subsurface Multi-spectral Contamination Monitor (SMCM). The SCM/SIMS was used to perform surface beta contamination surveys of the pavement in the RCA yard, exteriors of buildings and a water storage tank, and the floor of a radioactive Material Storage Area. The SMCM was utilized to perform surface and sub-surface gamma measurements of the paved areas in the RCA yard and open land areas both inside and outside of the RCA yard.
Highlights of the survey include:
- Recorded approximately 1.2 million surface measurements for beta contamination utilizing the SCM
- Recorded approximately 4350 gamma spectra utilizing the SMCM
- Surveyed approximately 7400 m2 in 10 days
- Generated 47 individual survey reports
- Demonstrated that paved area and building surfaces do not contain contamination above the investigation criteria established for the survey
- Demonstrated that open land areas within and immediately adjacent to the RCA yard do not contain radioactive material above the investigation criteria established for the survey
