Tuesday, December 06, 2011 8:51 AM Goshen, John Calvert Cliffs ISFSI License Renewal During our recent ( 11/30/11) conference call in regards to Calvert Cliffs ISFSI License Renewal a couple of questions were raised by the NRC. Below are the questions and their associated responses:
- 1.
Where do we have our air particulate filter samples analyzed? - The air filters to be sampled are sent to Constellation Energy's lab located at Constellation's Fort Smallwood facility in Anne Arundel county, Maryland.
- 2.
What is the instrument we use to measure the weekly beta activity collected from the air particulate filters? -
Samples are analyzed by an LB5100 Tennelec.
- 3.
What is the uncertainty associated with measuring the beta activity? - The uncertainty of the beta analysis is whichever is greater; 2 sigma of the calculated result or 3 sigma of the MDA. The LlMS (the software used to calculate the results) calculates both values automatically and returns the greater of the two in the reports.
If you have further questions please contact me.
