RESPONSE TO SECOND REQUEST FOR ADDITIONAL INFORMATION RELATED TO LICENSE AMENDMENT REQUEST FOR CHANGING TECHNICAL SPECIFICATION TABLE 3.3.1.1-1 FUNCTION 7, "SCRAM DISCHARGE VOLUME WATER LEVEL- HIGH" Attachment 1 Page 1 of 1 Response to Request for Additional Information NRC RAI: In its letter dated July 31, 2014 (ADAMS Accession No. ML14206A011), the NRC staff requested clarification of why the licensee used a frequency of 24 months to calculate instrument drift, since this is not the surveillance frequency defined in the CGS TSs. In the licensee's response dated August 28, 2014, the licensee discussed that it recognized that using 24 months becomes non-conservative for establishing the instrument drift. The licensee stated that it is recalculating the as-found tolerance (AFT)using the drift associated with 18 months; however, the recalculated value for AFT was not provided in the response.
WA Horin - Winston & Strawn (email)
The NRC staff has determined the recalculated value of the AFT is needed to complete its technical evaluation of the licensee's application.
RR Cowley - WDOH (email)
Please provide the recalculated value of the AFT for function 7b in TS Table 3.3.1.1-1 within 30 days of the date of this letter.Energy Northwest Response: The recalculated AFT for Function 7.b in Table 3.3.1.1-1 is plus or minus 0.73 inches (1.11% of Calibrated Span). The methodology applied in calculating the AFT is as described in Reference 2 however, some input parameters have been updated to reflect the revised system design.In addition to the changes to Function 7.b inputs, a change has been made to the design of the Function 7.a instrumentation as well. Specifically, level transmitters (CRD-LT-1 2A, B, C & D) which were to be replaced by Ametek transmitters will continue to be supplied by Gould. The change in approach for Function 7.a instrument design does not impact the changes to Function 7.a description and added surveillance for Function 7.a requested in Reference 1.Updates to the prior submittals (Reference 2 and Reference

As-Found Tolerance (AFT) and As-Left Tolerance (ALT)
This is the 100% range of the instrument.
For those instruments subject to the requirements of TSTF-493, Setting Tolerance has two parts. As-Found Tolerance (AFT) and As-Left Tolerance (ALT).
Any further increase above the centerline of the upper sensing diaphragm affects the accuracy of the measured value. Once the upper sensing diaphragm is fully submerged no further increase in level will result in a detected level change. Therefore, the upper allowable value is limited by design to the centerline of the upper sensing diaphragm.
AFT is defined as the bounds, within which the setpoint is expected to be found at the end of surveillance, and ALT is defined as the bounds within which the setpoint must be adjusted at the end of surveillance.
The upper sensing diaphragm centerline elevation for these transmitters is 529'-9". Therefore, an Upper Allowable Value of 529'-9" will be used; this is in agreement with the Tech. Spec.** NOTE: With the upper allowable value of 529'-9" per Tech Specs, the maximum setting is 529'-8.0.8 (529'-9" -0.92.).& NOTE: These AF/AL Tolerances are onlV for CRID-LIS-613GC CRD-L13D an.d...aCRD.LI..6.3F...S.U.M.MA.RY.TALE DE.$LETED.

* NOTE: The Instrument accuracy is specified from centerline of the diaphragm of the reference leg to centerline of the upper sensing diaphragm. This is the 100% range of the instrument. Any further increase above the centerline of the upper sensing diaphragm affects the accuracy of the measured value. Once the upper sensing diaphragm is fully submerged no further increase in level will result in a detected level change. Therefore, the upper allowable value is limited by design to the centerline of the upper sensing diaphragm. The upper sensing diaphragm centerline elevation for these transmitters is 529'-9". Therefore, an Upper Allowable Value of 529'-9" will be used; this is in agreement with the Tech. Spec.
** NOTE: With the upper allowable value of 529'-9" per Tech Specs, the maximum setting is 529'-8.0.8 (529'-9" - 0.92.).

RESPONSE TO SECOND REQUEST FOR ADDITIONAL INFORMATION RELATED TO LICENSE AMENDMENT REQUEST FOR CHANGING TECHNICAL SPECIFICATION TABLE 3.3.1.1-1 FUNCTION 7, "SCRAM DISCHARGE VOLUME WATER LEVEL- HIGH" Page 1 of 1 Response to Request for Additional Information NRC RAI:

In its letter dated July 31, 2014 (ADAMS Accession No. ML14206A011), the NRC staff requested clarification of why the licensee used a frequency of 24 months to calculate instrument drift, since this is not the surveillance frequency defined in the CGS TSs. In the licensee's response dated August 28, 2014, the licensee discussed that it recognized that using 24 months becomes non-conservative for establishing the instrument drift. The licensee stated that it is recalculating the as-found tolerance (AFT) using the drift associated with 18 months; however, the recalculated value for AFT was not provided in the response. The NRC staff has determined the recalculated value of the AFT is needed to complete its technical evaluation of the licensee's application.

Please provide the recalculated value of the AFT for function 7b in TS Table 3.3.1.1-1 within 30 days of the date of this letter.

Energy Northwest Response:

The recalculated AFT for Function 7.b in Table 3.3.1.1-1 is plus or minus 0.73 inches (1.11% of Calibrated Span). The methodology applied in calculating the AFT is as described in Reference 2 however, some input parameters have been updated to reflect the revised system design.

In addition to the changes to Function 7.b inputs, a change has been made to the design of the Function 7.a instrumentation as well. Specifically, level transmitters (CRD-LT-1 2A, B, C & D) which were to be replaced by Ametek transmitters will continue to be supplied by Gould. The change in approach for Function 7.a instrument design does not impact the changes to Function 7.a description and added surveillance for Function 7.a requested in Reference 1.

Updates to the prior submittals (Reference 2 and Reference 3) are provided in Attachments 2 & 3, with changed text depicted by dotted underline. Note that information which has not changed is not included except as needed to provide context to the information which did change.

None of the changes described above or included in Attachments 2 or 3 impact the Reference 1 conclusions for no significant hazards or environmental considerations.

For those instruments subject to the requirements of TSTF-493, Setting Tolerance has two parts. As-Found Tolerance (AFT) and As-Left Tolerance (ALT).

AFT is defined as the bounds, within which the setpoint is expected to be found at the end of surveillance, and ALT is defined as the bounds within which the setpoint must be adjusted at the end of surveillance.

  • NOTE: The Instrument accuracy is specified from centerline of the diaphragm of the reference leg to centerline of the upper sensing diaphragm. This is the 100% range of the instrument. Any further increase above the centerline of the upper sensing diaphragm affects the accuracy of the measured value. Once the upper sensing diaphragm is fully submerged no further increase in level will result in a detected level change. Therefore, the upper allowable value is limited by design to the centerline of the upper sensing diaphragm. The upper sensing diaphragm centerline elevation for these transmitters is 529'-9". Therefore, an Upper Allowable Value of 529'-9" will be used; this is in agreement with the Tech. Spec.
    • NOTE: With the upper allowable value of 529'-9" per Tech Specs, the maximum setting is 529'-8.0.8 (529'-9" - 0.92.).
