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.

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.
