Building Through-thickness expansion will be monitored every six months, consistent with the monitoring interval for CCI of Tier 3 locations This interval is appropriate because ASR is a relatively slow moving process and the concrete at Seabrook St<ition has been in existence for decades.
There is no reason to expect a sudden acceleration of ASR development. Hence, structural tmplications will not change significantly in a short time period of six months.

Enclosure 3 to SBK-L-17156 NextEra Energy Seabrook, Application for Withholding Proprietary Information from Public Disclosure and Affidavit
U.S. Nuclear Regulatory Commission SBK-L-17156 /Enclosure 3 I Page 2 NEXTera.
EN~~~~
NextEra Energy Seabrook, LLC AFFIDAVIT IN SUPPORT OF APPLICATION FOR WITHHOLDING PROPRIETARY INFORMATION FROM PUBLIC DISCLOSURE County of Rockingham )
)
State of New Hampshire )
I, Eric McCartney, being duly sworn according to law, depose and state the following:
(1) I am the Regional Vice President - Northern Region ofNextEra Energy Seabrook, LLC (NextEra Energy Seabrook), and have been delegated the function of reviewing the information described in paragraph (3) which is sought to be withheld, and have been authorized to apply for its withholding.
(2) I am making this Affidavit in conjunction with NextEra Energy Seabrook's "Application for Withholding Proprietary Information from Public Disclosure" accompanying this Affidavit and in conformance with the provisions of 10 CFR Section 2.390.
(3) The information sought to be withheld is contained in Enclosure 1 ofNextEra Energy Seabrook's letter SBK-L-17156, Eric McCartney (NextEra Energy Seabrook) to U.S. Nuclear Regulatory Commission, entitled "Response to Request for Additional Information Regarding License Amendment Request 16-03 Related to Alkali-Silica Reaction (CAC No. MF8260)."
(4) The information sought to be withheld is considered to be proprietary and confidential commercial information because alkali-silica reaction (ASR) is a newly-identified phenomenon at domestic nuclear plants. The information requested to be withheld is the result of several years of intensive NextEra Energy Seabrook effort and the expenditure of a considerable sum of money. This information may be marketable in the event nuclear facilities or other regulated facilities identify the presence of ASR. In order for potential customers to duplicate this information, similar technical programs would have to be performed and a significant manpower effort, having the requisite talent and experience, would have to be expended. The extent to which this information is available to potential customers diminishes NextEra Energy Seabrook's ability to sell products and services involving the use of the information. Thus, public disclosure of the information sought to be withheld is likely to cause substantial harm to NextEra Energy Seabrook's competitive position and NextEra Energy Seabrook has a rational basis for considering this information to be confidential commercial information.
U.S. Nuclear Regulatory Commission SBK-L-17156 I Enclosure 3 I Page 3 (5) The information sought to be withheld is being submitted to the NRC in confidence.
(6) The information sought to be withheld has, to the best of my knowledge and belief, consistently been held in confidence by NextEra Energy Seabrook, has not been disclosed publicly, and not been made available in public sources.
(7) The information is of a sort customarily held in confidence by NextEra Energy Seabrook, and is in fact so held.
(8) All disclosures to third parties, including any required transmittals to the NRC, have been or will be pursuant to regulatory provisions and/or confidentiality agreements that provide for maintaining the information in confidence.
I declare that the foregoing affidavit and the matters stated therein are true and correct to the best of my knowledge, information, and belief. Further, the affiant sayeth not.
