Dear Sir or Madam:
On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued Reference 1 to all power reactor licensees and holders of construction permits in active or deferred status. Enclosure 1 of Reference 1 requested each addressee in the Central and Eastern United States (CEUS) to Entergy Nuclear Northeast Entergy Nuclear Operations, Inc.
James A. FitzPatrick NPP P.O. Box 110 Lycoming, NY 13093 Tel 315-342-3840 Lawrence M. Coyle Site Vice President - JAF
JAFP-13-0 122 Page 2 of 2 submit a written response consistent with the requested seismic hazard evaluation information (items 1 through 7) by September 1 2013. On February 15, 2013, NRC issued Reference 2, endorsing the Reference 3 industry guidance for responding to Reference 1. Section 4 of Reference 3 identifies the detailed information to be included in the seismic hazard evaluation submittals.
On April 9, 2013, NEI submitted Reference 4 to NRC, requesting NRC agreement to delay submittal of some of the CEUS seismic hazard evaluation information so that an update to the EPRI (2004, 2006) ground motion attenuation model could be completed and used to develop that information. NEI proposed that descriptions of subsurface materials and properties and base case velocity profiles (items 3a and 3b in Section 4 of Reference 3) be submitted to NRC by September 12, 2013, with the remaining seismic hazard and screening information submitted to NRC by March 31, 2014. In Reference 5, NRC agreed with this recommendation. Reference 6 contained Entergy's commitment to follow the approach described in Reference 4.
The attachment to this letter contains the requested descriptions of subsurface materials and properties and base case velocity profiles for JAF. The information provided in the attachment to this letter is considered an interim product of seismic hazard development efforts being performed for the industry by EPRI. The complete and final seismic hazard report(s) for JAF will be provided to the NRC in our seismic hazard submittal by March 31, 2014, in accordance with Reference 5.
This letter contains no new regulatory commitments. If you have any questions regarding this report, please contact ChrisM. Adner, Licensing Manager, at 315-349-6766.
I declare under penalty of perjury that the foregoing is true and correct. Executed on 121h day of September, 2013.
Sincerely, LMC/CMA/mh

JAFP-13-0122 Attachment JAF Descriptions of Subsurface Materials and Properties and Base Case Velocity Profiles Page 1 of 5 JAF Plant Description The basic information used to create the site geologic profile at the Fitzpatrick Nuclear Power Plant (JAF) is shown in Table 1. This profile was developed using information documented in Ref. 1. As indicated in FSAR documents, the safe-shutdown earthquake (SSE) Control Point is defined at the top of Ordovician Oswego sandstone, elevation 260, and the profile was modeled up to the surface. For dynamic properties of soft rock layers, modulus and damping curves were represented with 2 models. The first model used rock curves taken from Ref. 2, the second model assumed linear behavior. These dynamic property models were weighted equally. For dynamic properties of the basal till layer, modulus and damping curves were also represented with 2 models. The first model used soil curves taken from Ref. 2, the second model used soil curves taken from Ref. 3 and Ref. 4. These dynamic property models were weighted equally. To model the profile, rock modulus and damping curves from Ref. 2 were paired with soil modulus and damping curves from Ref. 2, and linear rock modulus and damping curves were paired with soil modulus and damping curves from Ref. 3 and Ref. 4.
The 3 base-case shear-wave velocity profiles used to model amplification at the site are shown in Figure 1. Profiles 1, 2, and 3 are weighted 0.4, 0.3, and 0.3, respectively. Thicknesses, depths, and shear-wave velocities (Vs) corresponding to each profile are shown in Table 2.
