program is segmented with no clear mechanism to provide an integrated look at all the elements in the program. The intercomparison studies are handled by one individual, the daily check trends are handled by the gamina spectroscopy computer and only provides warning flags if a parametec is out of bounds, and different aspects of calibrations are handled by different peopl Divisions between QA elements such as these reduce the possibilities of detecting and correcting adverse ~ measurement performance before serious deficiencies aris The inspector noted that calibration records can be difficult to recover from the licensee document / records control system. The data for the current calibrations were recovered but not for the previous calibrations. The inspector found that for some geometries, records showed that confirmations were made of the new detector efficiencie Though not required by the written calibration procedures, such confirmations are considered good laboratory practice and, if done, they should be performed consistently for all possible geometries. The inspector was informed that the QA program is being reviewed by the corporate office to develop a uniform laboratory QA program for Hatch and Vogtle. The licensee agreed to evaluate the current QA program for improvements in regard to the inspector's comments. The results of this evaluation will be- reviewed in a subsequent inspection (IFI 50-321/86-21-01).

Confirmatory Measurements (84725)
During the inspection, reactor coolant and selected plant effluent / process streams were sampled and analyzed for radionuclide concentrations using the licensee and NRC Region II Mobile Laboratory gamma ray spectroscopy system ,
The purpose of these comparative measurements was to verify the licensee's ability to measure radionuclides accurately in various plant systems and effluent streams. Licensee's counting geometries studied included the following: 1000 cc liquid marinelli, 1000 cc gas marinelli, 14 cc gas vial,  -
50 mi bottle, 47 ml millipore particulate filter and charcoal cartridg Comparisons of licensee and NRC results are listed in Table 1 with the acceptance criteria given in Attachment The results showed agreement for the 50 m1 bottle, particulate filter, 14 cc gas vial, and 1000 cc liquid marinelli geometry. Three of five isotopes showed agreement for the 50 m1 bottle geometry, but a review of the calibration data and other validation checks indicate that the calibration was adequate. The inspector noted that there was some difficulty with the sample split s For the charcoal cartridge geometry, the inspector noted a high bias (>20%)
in the analysis for both detectors with one detector system in disagreemen This discrepancy could not be accounted for during the inspector's revie The results for the 1000 cc gas marinelli was in disagreement, biased high compared to the NRC results. Upon investigation, the inspector questioned the volume used for this geometry and requested the licensee to verify the volume for this geometry and the 14 cc gas vial. The licensee informed the inspector that 1000 cc had been used for approximately one year. The licensee's volume verification indicated an actual volume of approximately 1250 cc. This accounts for some of the problems noted in the disagreement between the licensee's measuremetits using this geometry, versus the NRC's measurement The inspector informed the licensee that this would be considered a violation; failure to make adequate surveys (50-321/86-02, 50-366/86-02). The inspector also noted that though agreement was obtained with the 14 cc gas vial geometry, the licensee used a 14 cc volume when the verified volume was approximately 14.5 c One violation was identified - failure to make adequate survey .

ATTACHMENT 1 CRITERIA FOR COMPARING ANALYTICAL MEASUREMENTS This attachment 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 progra In these criteria, the judgement limits are variable in relation to the comparison of the NRC's value to its associated uncertainty. As that ratio, referred to in this program as " Resolution," increases, the acceptability of a licensee's measurements should be more selective. Conversely, poorer agreement must be considered acceptable as the resolution decrease RATIO = LICENSEE VALUE NRC REFERENCE VALUE Resolution   Agreement

The criteria are based on an empirical relationship which combines prior experience and the accuracy needs of this progra In these 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, referred to in this program as " Resolution"2 increases, 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 decrease For comparison purposes, a ratio      r of 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 listed in Table .1 below. Values outside of the agreement ratios for a selected nuclide are considered in disagreemen " Resolution = NRC Reference Value for a Particular Nuclide      '

,y ENCLOSURE Criteria for Comparing Analytical Measurements This enclosure provides criteria for comparing results of capability tests and verif' cation measurements. The criteria are based on an empirical relationship which combines prior experience and the accuracy needs of this progra In these 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, referred to in this program as " Resolution"2 increases, 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 decrease For comparison purposes, a ratio r of 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 listed in Table .1 below. Values outside of the agreement ratios for a selected nuclide are considered in disagreemen " Resolution = NRC Reference Value for a Particular Nuclide '
