Inspector Observations The following are observations the NRC inspectors discussed with the licensee during the exit interview on May 8, 1987.
These observations are not violations, deviations, unresolved items, or open items.
These observations were identified for licensee consideration for pragram improvement, but the observations have no specific regulatory requirements.
The licensee stated that the observations would be reviewed.
a.
Calibration Standards Verification - The licensee was not using two independent standard solutions for calibration and measurement quality control.
The licensee was unable to verify the integrity of the standard solutions.
The licensee had not initiated a two standards program which includes one standard stock solution L
.
..
-4-
,
dedicated for instrument calibration and another independent standard stock solution dedicated for quality: control, b.
Quality Control Charts - The licensee was not'using quality control charts to trend and evaluate biases experienced in daily or periodic quality control analyses. The licensee had not initiated the use of quality control charts so as to recognize biases in calibration standard data and changes and trends in instrument performance.
3.
Program Areas Inspected l
The following program areas were inspected.
Unless otherwise noted, the inspection;was completed and revealed no violations, deviations, unresolved ittms, or open items.
Notations after a specific. inspection item are_used to identify the following:
I = item not inspected or only partially inspected; V = violation, D = deviation; U = unresolved item; and 0 = open item.

Nonradiological Water Chemistry Confirmatory Measurements
]
During the inspection, standard chemical solutions were provided to the
!
licensee for. analysis. - The standard solutions were prepared by the l
Brookhaven National Laboratory (BNL), Safety and Environmental Protection l
c Division, for the NRC.
The standards were analyzed by the licensee using
~
^
routine methods and equipment.
The analysis of chemical standards is used
to verify the licensee s capability to monitor chemical parameters in i
various ~ plant systems with respect to Technical Specification requirements
.
,
and' other industry standards.
In addition, the analysis of standards is i
used to evaluate the licensee's analytical ;nredures with respect to j
accuracy and precision.
j The results of the measurements comparison are listed in. Attachment 2.
Attachment 3 contains the criteria used to compare results.
All standards were' analyzed in-triplicate.
The licensee's original analytical results indicated that 26 of,the 29 results were in agreement.
Those analytical l
results which were found in disagreement after the first ion chromatograph
,
analysis were rerun by the licensee in an attempt to resolve any problems
!
associated with-sample preparation or analysis..The licensee was able to j
resolve the analytical problems associated with the_ ion chromatograph and l
the rerun analysis results were all in agreement.
!
!
As part of the inspection, actual inplant water samples were split between
!
-the licensee and the NRC in order to verify the licensee's measurement I
capabilities on actual plant water samples.
The analyses will be performed by licensee using their. normal methods and instrumentation and by BNL for the NRC Region IV. -The analyses to be performed are baron, fluoride, and chloride on a reactor. coolant sample; and iron, copper',
nickel, chromium, fluoride, chloride, and sulfate on a condensate water
' sample.
On completion of the analyses by both laboratories, the results j
will be compared by the NRC Region IV office and the intercomparison results will be documented in a subsequent NRC inspection report.
2.
Radiological Confirmatory Measurements Confirmatory measurements were performed by the licensee on liquid
radiochemistry samples prepared by the Radiological Environmental Sciences i
Laboratory (RESL) in Idaho Falls, Idaho.
The samples were provided to the licensee for analysis in April 1986.
The licensee's analytical results j
were compared to the known sample activities and the results of the l
'
comparisons are presented in Attachment 4 for official documentation.
Attachment 5 contains the criteria used to compare results.
The
licensee's results for the 1986 RESL sample were in 71 percent agreement.

Criteria For Comparing Analytical Measurements This attachment provides criteria for comparing results of capability tests.
In these criteria the judgement limits are based on the uncertainty of the ratio of the licensee's value to the NRC value.
The following steps are performed:
(1) the ratio of the licensee's value to the NRC value is computed Licensee Value (ratio =
NRC Value
);
(2) the uncertainty of the ratio is propagated.1 If the absolute value of one minus the ratio is less than or equal to twice the ratio uncertainty, the results are in agreement.

tests and verification measurements. The criteria are based on an empirical
'
relationship established through prior experience and this program's analytical

requirements.
In these criteria, the judgement' limits vary in relation to the comparison of the resolution.
