Thank you for your letter of December 21, 2017, (ML17362A041) which provided clarifying information to supplement your September 21, 2017, reply (ML17269A031) to the Notice of Violation concerning calibration of the main steam line and containment/drywell high range radiation monitors. The Notice of Violation was issued on August 22, 2017, in NRC Inspection Report 05000416/2017012 (ML17235B265).

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.
The NRC identified several discrepancies in your initial response that required clarification. We have reviewed these clarifications in conjunction with your initial response to the Notice of Violation and find that they address the violation and the corrective actions taken. Following review of your responses to the Notice of Violation, we concluded that the surveillances performed on the main steam line and containment/drywell high range radiation monitors in response to the Notice of Violation demonstrate reasonably accurate instrument responses. However, the changes to the calibration procedures themselves warrant additional review. In particular, we noted that the procedures continue to allow tolerances significantly wider than industry norm. We will review the implementation of your corrective actions during a future inspection to determine that full compliance has been achieved and will be maintained.

SUBJECT: GRAND GULF NUCLEAR STATION, UNIT 1, RESPONSE TO CLARIFICATION OF INITIAL RESPONSE TO A NOTICE OF VIOLATION AND NUCLEAR REGULATORY COMMISSION INSPECTION REPORT 05000416/2017012

Dear Mr. Larson:

Thank you for your letter of December 21, 2017, (ML17362A041) which provided clarifying information to supplement your September 21, 2017, reply (ML17269A031) to the Notice of Violation concerning calibration of the main steam line and containment/drywell high range radiation monitors. The Notice of Violation was issued on August 22, 2017, in NRC Inspection Report 05000416/2017012 (ML17235B265).

The NRC identified several discrepancies in your initial response that required clarification. We have reviewed these clarifications in conjunction with your initial response to the Notice of Violation and find that they address the violation and the corrective actions taken. Following review of your responses to the Notice of Violation, we concluded that the surveillances performed on the main steam line and containment/drywell high range radiation monitors in response to the Notice of Violation demonstrate reasonably accurate instrument responses. However, the changes to the calibration procedures themselves warrant additional review. In particular, we noted that the procedures continue to allow tolerances significantly wider than industry norm. We will review the implementation of your corrective actions during a future inspection to determine that full compliance has been achieved and will be maintained.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice and Procedure," a copy of this letter will be made available electronically for public inspection in the NRC Public Document Room or from the NRC's Agencywide Documents Access Management System (ADAMS), accessible from the NRC's Web site at http://www.nrc.gov/reading-rm/adams.html.
