Mr. liarold Foster, Manager ltuclear Materials Safeguards Ocawer R Columbia, S. Carolina 29205 Gentlemen:
This will serve as a formalization of our discussion held at i;RC lieadquarters April 17, 1979 pertaining to your current LEID model.
The Westinghouse-Columbia LEID model needs to be modified to assure proper treatment of systematic errors.
Systematic error covariance is a function of measurement systems and standards, not just material ty pe.
Measurement data must be checked for outliers and absolute systematic errors must be multiplied times the number of items.
5hould you have questions or com.ents, please contact our Mr. James Blaylock.
Sincerely, Jates G. bartlow, Chief Maferial Control & Accountability Licensing Branch Division of Safeguards cc:
