Subject:
LaSalle County Station Unit 2 10CFR50.55(e) Notification 83-01 Correction to Final Report, Riley Temperature Indicating Switches NRC Docket No. 50-374 Reference (a):
C.W.
Schroeder letter to J.G. Keppler dated March 16, 1983.
(b):
C.W. Schroeder letter to J.G. Keppler dated May 3, 1983.
(c):
C.W. Schroeder letter to J.G. Keppler dated June 3, 1983.
Dear Mr. Keppler:
The purpose of this letter is to correct a statement made in 4
Reference (c).
The Unit 2 Riley temperature switches have not yet been recalibrated to the modified calibration procedure suggested by Riley, i
~ 0nly the Unit 1 temperature switches have been recalibrated at this time.
We will complete the calibration on Unit 2, using the same calibration procedure as Unit 1, prior to fuel load.
If there are any questions in this matter, please contact this office.
Very truly yours, k
