Analytical procedure-Evaluation During the. inspection, standard chemical solutio $ were submitted to the y licensee:for analysi The standard solutions were prepared by the-
  • Brookhaven National Laboratory for the NRC, and the standards 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 q-Specification requirements and other regulatory requirements. In addition, the analysis of standards is used to evaluate the licensee's analytical

. procedures with1 respect to accuracy and precisio The results of the standard measurements comparison indicated that two.out of thirty comparisons' were in disagreement under the criteria used for comparing results ('ees attachment 1). The results of the comparisons are listed in Table 1. ~

The hydrazine and silica'results reported in Table 1 are reruns. The NRC'

,? l standards identified that the 1 cm cell used in the spectrophotometric analysis for~hydrazine and silica was too small for good resolution and accuracy.at~ the lower concentrations. of the two analytes. - The licensee-re an the hydrazine analysis using a 5 cm cell in a new instrument. The results improved, but were still biased low. The silicas were rerun using a'2 cm cell. The results were good and the bias'was eliminate ';

inadequate temperature control. The NRC standards were made up and- !

analyzed in a temperature of about 25 C and the licensee's room i temperature was.about 21 When the temperature difference was j compensated for,-the boron result on the boron standard that was in I I

, 3 disagreement was. reduced by 2%. The inspector recommended better temperature control for both the hot and cold laboratorie The fluoride, chloride and sulfate standards were rerun. The licensee's control standards identified a problem with the ion chromatograph. The licensee replaced the columns in the instrument and the results were well within the acceptance criteri . Measurement Control Verification of the licensee's measurement capabilities on actual plant- ;

water samples is done by splitting samples with the licensee and BNL. The l condensate sample was taken for anion analysis, .the feedwater sample was I taken for iron and copper analyses, the hot well sample was taken for hydrazine analysis and the holding tank was taken for boron analysis. The condensate sample was spiked with a standard solution of fluoride,-

chloride and sulfate and the feedwater sample was spiked with a standard solution of iron and copper. The standard spike solutions were prepared by BNL for the NRC. On completion of the analyses by BNL and the licensee, an evaluation will be made (Inspection Follow-up Item 50-344/87-09-01).

Two independent standard. stock solutions for calibration and measurement l contral'were being used. The licensee was able to identify a degenerated standard solution and verify the quality of the standard The licensee has generated calibration curves that were statistically fit to the data points. The linear regression program was computerized. The i licensee generated control charts with acceptance criteria of 2 sigma and an unacceptable parameter of 3 sigma. In some charts, the licensee was using control standards with twice the concentration as the samples they I were analyzing. The error in the measurement system was not reflected for the concentration of the analyte being determined. The licensee will correct this by generating control charts with standards in approximate i concentrations of the analytes being analyze ~

4. Exit Interview q The inspector met with the licensee representatives (denoted in paragraph 1) at the conclusion of the inspection on May 22, 1987, and summarized the scope and findings of the inspection. At no time during this inspection (
