"denotes those present at the exit interview.
The inspector also interviewed other licensee employees including members of the chemistry staff.
Measurement Control Evaluation This program verifies the licensee's measurement capabilities on actual plant water samples.
The radwaste tank, standby liquid control tank, and filters from the condensate and reactor water are sampled and duplicate samples are obtained and sent to the Brookhaven National Laboratory,(BNL)
for independent verification of analysis.
Chloride and silica analyses will be performed on the radwaste tanks, boron analysis on the standby liquid control tanks, and iron, copper, nickel, and chromium analyses on the acid digested filters.
On completion of the analyses by both labora-tories, a statistical evaluation will be made (Inspector Follow-up Item 50-387/85-27-01 and 50-388/85-22-01).
Anal tical Procedures Evaluation During the inspection, standard chemical solutions were submitted to the licensee for analysis.
The standard solutions were prepared by the,,'rookhaven National Laboratory for the NRC Region I, and the standards were analyzed by the licensee using normal methods and equipment.
The analysis of standards is used to verify the licensee'
capability to monitor chemical parameters in various plant systems with respect to Technic'al Specification requirements and other regulatory requirements.
In addi-tion, the analysis of standards is used to evaluate the licensee's analytical procedures with respect to accuracy and precision.
The results of the standard measurements comparison indicated that, with the exception of three measurements, all of the results were in agreement under the criteria used for comparing results (see Attachment 1).
The results of the comparisons are listed in Table No violations were identified 4.
Exit Interview
While observing the licensee analyzing nickel, copper, chronium, and iron using the atomic absorption procedure, a one point calibration was'made.
The inspector advised the licensee that a one point calibration was poor laboratory practice because a change in the slope of the calibration curve would be very difficult to identify.
A minimum of two points is necessary to generate a reliable calibration curve.
The licensee stated that they would investigate this problem.
While reviewing the licensee's procedures, the inspector identified that some of the analytical procedures were not complete as they did not~ have the reagent preparations included.
There was a separate procedure ',for required reagents.
In the case of the boron mannitol titration procedure, five separate reagent preparation procedures are needed for a technician to perform the analysis.
The inspector identified that this could ~lead to problems.
The licensee stated that they would consider rewriting some of the procedures to incorporate the reagent preparation procedures.
The inspector reviewed the measurement control charts for chloride,,
silica, and iron.
The inspector suggested that control. charts be gener-ated for boron, nickel, copper, and chromium, and that any measurement required in the Technical Specifications and fuel warranty should have a control chart.
The licensee said that they will generate the charts.
The inspector met with the licensee representatives (denoted in paragraph 1) at the conclusion of the inspection on September 20, 1985, and summarized the scope and findings of the inspection.
At no time during this inspection was written material provided to the licensee by the inspecto a

ATTACHMENT Criteria For Com grin Anal tical 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 (ratio Licensee Value NRC value the uncertainty of the ratio is propagated.
If the absolute value of one minus the ratio i.s less than or equal to twice the ratio uncertainty, the results are in agreement.
