FEB 21 BBS Georgia Power Company ATTN: Mr. W. G. Hairston, III Senior Vice President -
Nuclear Operations P. O. Box 1295 Birmingham, AL 35201 Gentlemen:
SUBJECT:
NON-RADIOLOGICAL CONFIRMATORY MEASUREMENT RESULTS SUPPLEMENT TO INSPECTION REPORT N05. 50-424/88-46 AND 50-425/88-61 As part of a special NRC non-radiological chemistry confirmatory measurements study, in conjunction with Brookhaven National Laboratory (BNL), spiked liquid samples were brought to your Vogtle facility on October 17, 1988, for your analysis.
We are in receipt of your analytical results and the comparisons of your results to the NRC/BNL results are presented in Enclosure 1.
The acceptance criteria for these comparisons are discussed in Enclosure 2.
These results should be reviewed in greater detail by cognizant plant staff members.
These results will also be discussed during future NRC inspections.
Sincerely, Thomas R. Decker, Acting Chief Emergency Preparedness and Radiological Protection Branch Division of Radiation Safety and Safeguards Enclosures:

Criteria for Comparing Analytical Measurements This attachment provides ' criteria forcomparim results of the capability tests.
The acceptance limits are based on the uncerta'nty (standard deviation) of the ratio of the licensee's mean value (X) to the NRC sean value (Y), where
,
(1) Z = X/Y is the ratio, and (2) fopagation of the uncertainties of licensee's mea S is the uncertainty of the ratio determined from the x, and of the NRC's mean value, S.:
Thus, y

The results are considered to be in agreement when the bias in the ratio
-
(absolute value of difference between unity and the ratio) is less than or equal to twice the uncertainty in the ratio, i.e.
