Box 1700 Jackson, MS 39215-1700 NRC Senior Resident Inspector Grand Gulf Nuclear Station Port Gibson, MS 39150 Attachment 1 GNR0-2017/00059 Reply to Notice of Violation Attachment to GNR0-2017/00059 Page 2 of 2 REPL V TO NOTICE OF VIOLATION I. Cited Violation During a Nuclear Regulatory Commission (NRC) inspection conducted on June 10-14, 2017, a violation of NRC requirements was identified.

In accordance with the NRC Enforcement Policy, the violation is listed below: 1 O CFR 20.1501 (c) requires, in part, that the licensee shall ensure that instruments and equipment used for quantitative radiation measurements are calibrated periodically for the radiation measured.

Contrary to the above, since January 1, 2012, the licensee failed to ensure that instruments and equipment used for quantitative radiation measurements were calibrated periodically for the radiation measured.

Specifically, the licensee failed to properly calibrate the containment/drywell high range. radiation monitors and the main steam line radiation monitors us.ing industry accepted calibration methods and tolerances.

This violation is associated with a Green Significance Determination Process finding. II. The Reason for the Violation Entergy concurs with the violation.

The reason for the violation is that Entergy failed to have a procedure that sufficiently implemented industry standards to calibrate the subject radiation monitors.

After the issue was identified in 2012, Entergy failed to take timely actions to correct the condition, due to lapses in the implementation of the issue action plan. Ill. Corrective Steps Which Have Been Taken and Results Achieved Entergy has reviewed the previous calibrations performed and determined that, although the calibrations were not compliant with industry accepted calibration methods and tolerances, the monitors were operable/functional.

The Drywell and Containment Radiation Monitors have been successfully tested in accordance with NUREG-0737, per plant operating procedure 06-IC-1D21-R-1002.

This testing was performed using traceable and calibrated source material, a repeatable process, geometry, control of test fixtures, and was performed through all decades of response.

The Main Steam Line Radiation Monitors have been successfully tested in accordance with American National Standards Institute (ANSI) N13.1-1969, per plant operating procedure 06-IC-1D17-R-1002.

This testing was performed using traceable and calibrated source material, a repeatable process, geometry, control of test fixtures, and was performed through all decades of response.

Attachment to GNR0-2017/00059 Page 2 of 2 IV. Corrective Steps That Will be Taken There are no additional steps necessary to ensure continued compliance.

V. Date When Full Compliance Will be Achieved GGN achieved full compliance on September 21, 2017.
