Information Notice No. 83-12: Incorrect Boron Standards
SSINS No.: 6835 IN 83-12 UNITED STATES NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT WASHINGTON, D.C. 20555 March 18, 1983 Information Notice No. 83-12: INCORRECT BORON STANDARDS Addressees: All nuclear power reactor facilities holding an operating license (OL) or construction permit (CP). Purpose: This information notice is provided as a notification of a potentially significant problem pertaining to incorrect boron standards supplied by the J. T. Baker Chemical Company of Phillipsburg, New Jersey. An incorrect and non-conservative determination of the actual boron concentration of a pressurized water reactor's primary coolant system could result from the use of these incorrect standards. Since boiling water reactor (BWR) licensees are required to periodically determine boron concentration in their emergency, backup chemical shutdown systems, BWR licensees may use similar standards. It is expected that recipients will review this information notice for applicability to their facilities. No specific action or response is required at this time. Description of Circumstances: Consumers Power Company, Palisades Plant, received an order consisting of twentythree 500-ml bottles of 1000-ppm boric acid solution in water, to be used in its chemistry laboratory as standards. The principal use of these standards is for the standardization of sodium hydroxide solutions which are in turn used to determine the concentration of boron in the primary coolant system. Before using any of these standards, a verification test was performed on one of the twenty-three bottles. This titration analysis of the 1000-ppm standard indicated the boron concentration was 896 ppm. Two additional bottles were then analyzed, with chemistry supervision present, and these were found to contain 898 ppm, and 896 ppm of boron, respectively. All twenty-three bottles were then placed in hold in the facility store room. The safety significance is that the boron standard is used for standarization of sodium hydroxide which is in turn used to determine the boron concentration in the primary coolant system. Use of sodium hydroxide standardized with a lower-than-expected boron concentration would overestimate the boron concentration in the primary coolant system. Overestimation of the primary system boron concentration could reduce the capability to shut down the reactor and maintain the plant in a safe condition. 8212060383 . IN 83-12 March 18, 1983 Page 2 of 2 The Palisades plant supplier, the J. T. Baker Chemical Company, has been contacted about the concentration deficiency of the boron standard of Lot No. 133107 by both Consumers Power Company and by the Nuclear Regulatory Commission. Consumers Power Company issued a 10 CFR 21 report on December 22, 1982. The NRC asked the J. T. Baker Chemical Company to identify how Lot No. 133107 was distributed. According to J. T. Baker Company personnel in the Phillipsburg, N.J. office, all distributions are made to individual supply houses and cannot be traced beyond that point. They have identified all individual supply houses receiving more than one bottle of the boron standard from Lot No. 133107. These are as follows: o J. T. Baker Chemical Company Sales Office, Glen Ellyn, Illinois, twenty-three 500-ml bottles (these are the bottles which were ultimately sent to the Palisades Plant). o V. W. R. Scientific, Bridgeport, New Jersey, twenty-four bottles. o V. W. R. Scientific, Batavia, Illinois, twelve bottles. o V. W. R. Scientific, Brisbane, California, twelve bottles. If you have any questions about this matter, please contact the Regional Administrator of the appropriate NRC Regional Office, or this office. Edward L.
