DETAILS 1. Individuals Contacted

• J. Pelletier, Plant Manager

• M. Prystupa, Plant Chemist S. Jefferson, Assistant Plant Manager R. Leach, Chemistry and Health Physics 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 (0 pen) 85-03-01 IFI (84725) - The licensee did not have a measurement control program with independent standards for calibration and contro The licensee initiated a measurement control program, but control charts for boron, chloride (electrode), iron, nickel, copper, and chromium are needed. This item will remain ope (0 pen) 25-00-13 TI - The Temporary Instruction includes Modules 79501 and 79502. The inspection completed Module 7950 . Measurement Control Evaluation The licensee's measurement control program was verified through analysis of actual plant water samples. The standby liquid control tank and well water were sampled and duplicate samples were sent to Brookhaven National Laboratory (BNL) for independent verification. Boron analysis will be performed on the standby liquid control tank sample and chloride, silica, iron, nickel, copper, and chromium analyses on the well water sample. On completion of the analyses by both laboratories, a statistical evaluation will be made (Inspector Follow-up Item 85-38-01).

4. Analytica1' Procedures Evaluation During the inspection, standard chemical solutions were submitted by the inspector to the licensee for analysis. The standard solutions were prepared by BNL for NRC Region I, 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 requirements. In addition, 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 three out of twenty-one analyses were not in agreement under the criteria used for comparing results (see Attachment 1). The disagreements are not considered significant. The differences are less than 6% of the accepted value. The results of the comparisons are listed in Table . Exit Interview The inspector met with the licensee representatives (denoted in paragraph 1) at the conclusion of the inspection on December 5, 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 l

Al fACilMI:NI Criteria For Comparing Analytical Measurements This attachment provides criteria for comparing results of capability test 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 propagate If the absolute value of one minus the ratio is less than or equal to twice the ratio uncertainty, the results are in agreemen (ll-ratio l 2 2 uncertainty)
