Letter from J.G.
Keppler to C. Reed dated December 1, 1986
Dear Mr. Keppler:
This letter is in response to the inspection conducted by your office during the period October 27-30, 1986, of certain activities at Quad Cities Station.
The referenced letter indicated that certain activities appeared to be in violation of NRC requirements.
The Commonwealth Edison Company's response to the Notico ci Violation is provided in Attachment A.
If you have any further questions regarding this matter, please contact this office.
Very truly yours, 4/,

ATTACHMENT A COMMONWEALTH EDISON COMPANY RESPONSE TO NOTICE OF VIOLATION Response to Notice of Violation:
As a result of the inspection conducted on October 27-30, 1986, and in accordance with " General Policy and Procedures for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, (1985), the following violation was identified:
Item of Violation:
Unit 1 and Unit 2 Technical Specification 6.2.A.1 states that detailed written procedures covering items for normal startup, operation, and shutdown of the reactor, and other systems and components involving nuclear safety of the facility shall be prepared, approved and adhered to.
This requirement for the determination of boron concentration in the standby liquid control system in Unit 1 and Unit 2 Technical Specification 4.4.C.1 is implemented in Procedure QCP 600-9, " Determination of Sodium Pentaborate", (Revision 5, May 28, 1986).
This procedure, in Step Sa, requires the use of a 0.1000 N hydrochloric acid standard for standardizing the sodium hydroxide solution used in the analysis.
Contrary to the above, during the period of May to October 1986, the licensee failed to use a hydrochloric acid solution certified as a standard material to standardize the sodium hydroxide solution.
Discussion:
Until May 1986, the O.1 hydrochloric acid used for standardizing the sodium hydroxide solution was traceable by certificate to a National Bureau of Standards (NBS) primary reference of Potassium Acid Phthalate.
When a shipment of hydrochloric acid arrived at the station without a certificate, the hydrochloric acid used was switched to an ultrapure reagent which exceeds the requirement of the American Chemical Society's " Reagent Chemicals".
The station had certificates of purity for the ultrapure hydrochloric acid reagent that had been considered acceptable by the station as assure of quality.
The Station has since received certificates for the 0.1 N hydrochloric acid traceable to a NBS primary reference of Potassium Acid Phthalate and is currently using it to satisfy the requirements of the procedure.
I c
, Corrective Action Taken and the Results Achieved:
When the supply of hydrochloric acid arrived without certificates, the certificates were requested from the supplier.
The request was followed up and the certificates were received in October 1986.
The hydrochloric acid traceable to Fotassium Acid Phthalate was then utilized again.
Corrective Action to be Taken to Avoid Further Violations:
QCP 600-9, " Determination of Sodium Pentaborate", will be revised to require the station to prepare a solution from the primary standard Potassium Acid Phthalate to standardize the sodium hydroxide when a solution traceable to a primary standard is not available.
The primary standard of Potassium Acid Phthalate in crystal form will be kept as a backup at the station.
Date When Full Compliance Will be Achieved:
The Station is currently in full compliance.
The Station is using a hydrochloric acid solution certified as a standard material to standardize the sodium hydroxide solution.
The procedure change required to ensure proper standard preparation when traceable hydrochloric acid is not available will be implemented by March 1, 1987.
