Subject:
Vermont Yankee Nuclear Power Station License No. DPR-28 (Docket No. 50-271)
Supplement to Fourth-Interval Inservice Testing (IST) Program Plan On January 22, 2003, Vermont Yankee Nuclear Power Station (VY) submitted to the NRC a revised Inservice Testing (IST) Program as required by I OCFR50.55a(f)(4)(ii).
Following this submittal, several administrative errors were identified in the Program Plan.
Specifically, pages 58, 66, 80 of the Program Plan should contain the phrase "Intentionally Blank Page" and page 1 of Form 3 (VYPPF 7013.03) was corrected to state "Page 1 of 2" rather than "Page 1 of 3." These pages are being submitted and it is requested that the attached pages be inserted into our submittal as appropriate. identifies the commitments made in this letter. Attachment 2 contains the revised pages to the Program Plan.
If you have any questions on this transmittal, please contact Mr. Thomas B. Silko at (802) 258-4146.
Sincerely, Michael A. Balduzzi Vice President, Operations Attachments cc:

- 2.
Date of previous calibration:
I
/
- 3.
Found out of calibration at last calibration (Y)
(N)
- 4.
Review of instrument usage since previous calibration.
% Total Error Acceptable?
% Cal Error
% Loop Cal Error
% Total Error (4.d)
(4.a)
(4.b)
(4.c)
YES NO 4.a Calculate % calibration error as follows:
- 1) Calculate maximum as-found instrument output deviation from required output value.
- 2) Calculate the range over which the calibration is performed (i.e., CALmax - CALmin).
- 3) Divide the maximum output deviation by the calibration range.
- 4) Multiply by 100%.
4.b If an instrument loop is involved, and a loop calibration was not performed, then calculate the instrument loop calibration error as follows:
- 1) Calculate instrument loop component % calibration per Step 4.a above.
- 2) Calculate loop % error by taking the square root of the sum of the individually squared component
% calibration errors.
4.c Calculate the instrument % total error by adding the % calibration error calculated in Step 4.a and 4.b.
4.d If the % total error for the instrument of concern is less than or equal to the % required accuracy shown in the applicable Operations surveillance procedure that used the instrument, then note this in the Comment section below, and state that no adjustment of the test value is necessary.
4.e If the % total error for instrument of concern exceeded the required accuracy identified in the applicable Operations surveillance procedure, then complete Part 2.
