Subject:
Dresden Station Units 1, 2, and 3 Response to IE Inspection Report Nos. 50-10/79-15, 50-237/79-19 and 50-249/79-17 NRC Docket Nos. 30-10/237/249 Reference (a):
A. Davis letter to B. Lee, Jr. dated September 24, 1979
Dear Mr. Keppler:
The following is in response to an inspection conducted by Mr. J. Hiatt on August 28-31, 1979 of activities at Dresden Nuclear Power Station Units 1, 2
and 3.
Reference (a) indicated that one item appeared to be in noncompliance with NRC requirements.
Attachment A to this letter contains Commonwealth Edison Company's response to the identified item of noncompliance.
Please address any additional questions you may have concerning this matter to this office.
Very truly yours, D.

AITACHMENT A COMMONWEALTH EDISOF NRC Docket No. 50-10 AITACHMENT 50-237 RESPONSE TO NOTICE OF V' LATION 50-249 The item of non-compliance identified in Appendix A with the h"AC letter dated September 24, 1979, is responded to in the following para-graphs.
s 1.
Technical Specification 6.2.A.7 requires the preparation, approval,
~
and adherence to detailed written procedures for surveillance and testing requirements.
Technical Specification surveillance requirement 4.8.C re-quires the quarterly calibration of the Units 2/3 liquid effluent radiation monitor.
Contrary to the above, an unapproved procedure was used to cali-brate the Units 2/3 liquid effluent radiation monitor in the first and second quarters of 1979.
Corrective Action Taken and the Results Achieved On September 20, 1979, a Special Operating Procelure, SOP 415, received On-Site-Review and Approval and was utilized to calibrate the Units 2/3 off-line liquid effluent monitor. The procedure requires a linearity check of the monitor, correlates a gamma analysis (GeLi) of a predischarge tank sample to the monitor's response during the release of the tank, and uses the curve generated by the linearity check to graph
~
release concentration (uCi/ml) versus monitor response (cps). The monitor was successfully calibrated using this Special Operating Pro-cedure.
Corrective Action To Be Taken To Avoid Further Non-Compliance On October 1,1979, Dresden Chemistry Procedure DCP 2700-13 received On-Site Review and Approval. The procedure is similar to the Special Operating Procedure described above and will be used for subsequent calibration of the liquid effluent monitor for Units 2/3.
Date When Full Compliance Will Be Achieved Since the approved Chemistry Procedure DCP 2700-13 has been distributed, full compliance has been achieved.
