NRC Resident Inspector G. Maxwell
- Attended exit interview Confirmatory Measurements (84725)
During the inspection, reactor coolant and selected liquid and gaseous samples were sampled by the licensee and analyzed for radionuclide concentrations using the licensee's gamma spectroscopy system and the NRC Region II mobile laboratory.
The purpose of these comparative measurements was to verify the licensee's capability to accurately measure gamma emitting radionuclide concentrations in various plant systems and effluent streams.
Comparisons were made against the four detectors located in the chemistry counting room facility.
Sample types compared included the following:
(1) reactor coolant; (2) waste gas decay tank, (3) liquid waste monitor tank; and (4)
spiked charcoal and spiked particulate filters (provided to the licensee by the inspector).
A more detailed description of the sample types and geometries along with a comparison of the NRC and licensee results is listed in Attachment 1.
The methodology for determining agreement or disagreement is discussed in Attachment 2.
The results showed agreement for all compared radionuclides except for !odine-134 on Detector 3 (no.
12841137)
in the liquid reactor coolant sample, which was biased high.
Although the licensee was in agreement for Iodine-134 on the other three detectors, their results were significantly higher than the NRC result The inspector observed the sampling of the reactor coolant system and a
waste gas decay tank.
Proper sampling techniques and Health Physics practices were observed.

equality Assurance Survei llances The inspector reviewed the following equality Assurance Surveillance reports:
~R Surveillance Area (a)86-139 June 10, 1986 Radiochemistry (b)87-082 April 12, 1987 Chemistry Laboratory Practices (c)97-194 November 30, 1987 Radioactive Effluents Technical Specifications All findings noted in the surveillance reports were adequately and promptly addressed.
4.
Collocated TLDs (2500/22)
Temporary Instruction 2500/22 specifies data to be collected for collocated NRC and licensee environmental thermoluminescent dosimeters (TLDs).
The inspectors discussed the program with cognizant licensee representatives, and determined that all but four of the NRC TLDs were collocated with licensee TLDs.
The inspectors inspected four of the collocated sites and stated that the program would be completed during a
subsequent inspection.
5.
Summary The inspectors concluded that there was good agreement between the licensee and the NRC mobile laboratory gamma spectroscopy measurements.
The quality control program for the licensee's counting facility will be addressed during subsequent inspections.
6.
Exit Interview The inspection scope and results were summarized on June 9, 1988, with those persons indicated in Paragraph 1.
The inspectors described the areas inspected and discussed in detail the inspection results.

ATTACHMENT 2 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 program.
t 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~ of the licensee value to the NRC value 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 are considered in disagreement.
