• S. Matthess, Chemist G. Goncarovs, Plant Chemist T. Lantry, Assistant Chemistry Supervisor

• Denotes those present at the exit intervie The inspector also interviewed other licensee employees including members of the chemistry staf . Action on Previous Licensee Findings (Closed) 84-04-01 IFI - Control standaros, independent of calibration standards, were not plotted on control charts. The licensee now has a measurement control program where results are plotted on control chart Standards are plotted with warning parameters of 12 sigma and acceptance parameters of 2.5 sigm (0 pen) 25-00-13 TI - The inspection covered part of this item. Of the two modules included in the TI, Module 79501 was complete . Measurement Control Evaluation The licensee's measurement control program was verified through analysis of actual plant water samples. Service water, steam generator, blowdown, and reactor coolant were sampled and duplicate samples were sent to Brookhaven National Laboratory (BNL) for independent verificatio Chloride, fluoride, silica, iron, and copper analyses will be performed on the service water sample, hydrazine and ammonia analyses on the steam generator blowdown sample and boron analysis on the reactor coolant sample. On completion of the analyses by both laboratories, a statisti-cal evaluation will be made (Inspector Follow-up Item 85-24-01). Analytical Procedures Evaluation During the inspection, standard chemical solutions were submitted by the inspector to the licensee for analysis. The standard solutions were pre-pared by BNL for NRC Region 1, and were analyzed by the licensee using normal methods and equipment. The analysis of standards is used to verify the licensee's capability to monitor chemical parameters in various plant systems with respect to Technical Specification and other regulatory re-quirements. In addition, the analysis of standards is used to evaluate the licensee's analytical procedures with respect to accuracy and precisio f a

The results of the standard measurements comparison indicated that seven out of twenty six comparisons were in disagreement under the criteria used for comparing results (see attachment).

The inspector reviewed the calibration procedures and control charts associated with the analytical methods that were to be used to analyze the NRC standard chemical solutions. -The control standards results re-vealed that the specific ion electrode instrument was not working properly. Part of the electronics were bypassed and the chloride and fluoride control standards then came within the acceptable parameter. The licensee stated that this matter would be reviewed furthe Regarding ammonia calibration, the ammonia calibration was made with only one point. The inspector told the licensee that all calibrations should be made with a minimum of three points. The licensee generated an ammonia calibration curve with a freshly prepared standard and analyzed the olo standard solution against i The old standard was 10% high at the 300 ppm concentration 18% high at the 1000 ppm concentratio The licensee will develop calibration curves for all the spectrophotometric procedure This was the cause for the ammonia disagreements. The results of all of the comparisons are listed in Table . Exit Interview The inspector met with the licensee representatives (der.oted in paragraph 1) at the conclusion of the inspection on December 20,1>'85, and summa-rized the scope and findings of the inspection. At no time during this inspection was written material provided to the licensee by the inspecto .
