Dear Mr. Little:
Toledo Edison acknowledges receipt of your June 15, 1982 letter (log 1-637) and enclosures, Appendix, Notice of Violation and report 50-346/
82-15, referencing the violation of 10 CFR 50, Appendix B, Criterion XII.
This violation is listed as a Severity Level V (Supplement I).
Following an examination of the items of concern, Toledo Edison herein offers information regarding the item of violation.
Violation:
10 CFR 50, Appendix B, Criterion XII requires that measures shall be established to assure that tools, gauges, instru-ments, and other measuring and testing devices used in activities affecting quality are properly controlled, cali-brated, and adjusted at specified periods to maintain ac-curacy within necessary limits.
Contrary to the above:
Ilydrometers used to measure the specific gravity of electro-lyte in safety-related batteries, and rotameters used for containment local leak rate measurement were not calibrated (accuracy checked) at specified periods or prior-to-use to verify accuracy was within necessary limits.
Response
(1) Corrective action taken and the results achieved. The hydrometer manufacturer was consulted on the specified period for performing an accuracy check. The manu-facturer stated that the only check required was a receipt verification of accuracy using two separate, known solutions, and verifying the hydrometers accurate to ! 0.005.
Instrument records were checked and veri-fled that Toledo Edison has been doing this.
The rotameters were checked on April 30, 1982 and all found to be in agreement. The manufacturer was THE TOLEDO EDISON COMPANY EDISON PLAZA 300 MADISON AVENUE TOLEDO, OHIO 43652 8209130224 820907 kMl DR ADOCK 05000346 dl' Pna
Serial No. 1-277 July 19, 1982 Page 2 consulted on the specified period for performing an accuracy check.
It was determined that the rotameters should be check prior to each use, and once a month when in continuous use.
(2) Corrective action to be taken to avoid further non-compliance.
For the hydrometers no further action is required since consultation with the manufacturer verified our current program is in accordance with the manufacturer's recommendation.
For the rotameters a purchase order has been issued to purchase three rotameters traceable to the National Bureau of Standards for use as lab standards.
Each rotameter will then be checked prior to each use, and once a month when in continuous use.
(3) The date when full compliance is achieved. The Station is presently in full compliance of having the hydrometers and rotameters accuracy checked at specified periods or prior to use.
Very truly yours,
