'CONFIRMATORY MEASUREMENT RESULTS, SUPPLEMENT TO INSPECTION REPORT NOS. 50-335/87-24 AND 50-389/87-23 As part of the NRC Confirmatory Measurements Program, spiked liquid samples were sent on November 5, 1987, to your St.
Lucie facility for selected radiochemical analyses.
We are in receipt of your analytical results transmitted to us by your letter dated January ll, 1988, and subsequent to verification of your values as per our conversation by telephone on February 12, 1988, the following comparison of your results to the known values are presented in Enclosure 1 for your information,.
The acceptance criteria for the comparisons are listed in Enclosure 2.
In our review of these data all comparative results were in agreement.
These data should be reviewed in greater detail by your cognizant staff members for any significant trends in the data among successive years in which samples have been analyzed by your facility.
These results and any results from previous years pertaining to these analyses will be discussed at future NRC inspections.

Criteria for Comparing Analytical Measurements This enclosure provides criteria for comparing results of capability tests and verification measurements.
The criteria are based on an empirical relationship which combines prior experience and the accuracy needs of this program.
In this criteria, the judgement limits denoting agreement or disagreement between licensee and NRC results are variable.
This variability is a function of the NRC's value relative to its associated uncertainty.
As the ratio of the NRC value to its associated uncertainty, referred to in this program as
"Resolution"'ncreases, the range of acceptable differences between the NRC and licensee values should be more restrictive.
Conversely, poorer agreement between NRC and licensee values must be considered acceptable as 'the resolution decreases.
For comparison purposes, a ratio'f the licensee value to the NRC value for each individual nuclide is computed.
This ratio is then evaluated for agreement based on the calculated resolution.
The corresponding resolution and calculated ratios which denote agreement are l.isted in Table 1 below.
Values outside of the agreement ratios for a
selected nuclide are considered in disagreement.
