Mr. H. B. Tucker, Vice President Nuclear Production Department 422 South Church Street Charlotte, NC 28242 Gentlemen:

SUBJECT:

CONFIRMATORY MEASUREMENT RESULTS DOCKET NOS. 50-369, AND 50-370 As part of the NRC Confirmatory Measurements Program, spiked liquid samples were sent on July 22, 1985, to your facility for selected radiochemical analyses. We are in receipt of your analytical results transmitted to us by your letters dated October 1, and November 22, 1985, and subsequent to verification of your values as per our conversation by telephone on December 2, 1985.

The following comparison of your results to the known values are presented in Enclosure 2 for your information. The acceptance criteria for the comparisons are listed in.

In our review of the data, comparative results were in agreement for H-3, Sr-89 and Sr-90 analyses and disagreement for Fe-55.

This disagreement may be indicetive of a programmatic weakness and therefore, your attention is directed to determining the underlying cause for this disagreement. Furthermore, all data should be reviewed in greater detail by cognizant staff members for significant trends in the data among successive years in which samples have been analyzed by your facility.

These results an'd any results from previous years pertaining to these analyses will be discussed at future NRC inspections.

Sincerely, Roger D. Walker, Director Division of Reactor Projects
