-Buried Piping and Tanks Inspection Program)LRA Section B.2.1.24 describes the existing Buried Piping Inspection Program as consistent, with an enhancement, with GALL AMP XI.M34, "Buried Piping and Tanks Inspection." The applicant stated that the program provides aging management of carbon steel, galvanized steel, ductile cast iron, and gray cast iron buried piping susceptible to general corrosion, pitting, crevice corrosion, and microbiologically-influenced corrosion.
The applicant also stated that the program relies on the visual inspection of excavated piping, including the associated coatings and wrappings.
The applicant further stated that there are no buried tanks within the scope of license renewal. LRA Section B.2.2.4 describes the existing Buried Non-Steel Piping Inspection Program as a plant-specific program. The applicant stated that the Buried Non-Steel Piping Inspection Program is a condition monitoring program used to manage buried reinforced concrete piping and components in its service water system for cracking, loss of bond, increase in porosity and permeability, and loss of material.
The Buried Non-Steel Piping Inspection Program also manages buried stainless steel piping and components in the condensate storage and transfer system and fire protection systems for loss of material.Given the recent industry events involving leakage from buried or underground piping, the staff needs further information to evaluate the applicant's account for the industry and any plant-specific operating experience in its Buried Piping Inspection Program. This issue remains an open item as 01 3.0.3.1.2-1.
PSEG Response: On August 6, 2010, the NRC staff issued RAI B.2.1.24 requesting additional information about the Hope Creek Generating Station Buried Piping Program, including relevant information to evaluate the applicant's account for the industry and any plant-specific operating experience.
PSEG Nuclear responded to that request in its letter LR-N10-0323, dated September 1, 2010.After reviewing that response, the staff determined that additional information was required, and issued RAI B.2.1.24-02 on October 12, 2010. PSEG Nuclear provided that additional information in its letter LR-N10-0371, dated October 29, 2010.PSEG believes that the information provided in its License Renewal Application and the two letters described above constitute sufficient information for the NRC staff to close Open Item 01 3.0.3.1.2-1.

-Inaccessible Medium Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements)
LRA Section B.2.1.37 describes the new Inaccessible Medium Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program as consistent with GALL AMP XI.E3, "Inaccessible Medium Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements." The applicant stated that its program manages inaccessible medium voltage cables that are exposed to significant moisture simultaneously with significant voltage. The applicant stated that significant moisture is defined as periodic exposure to moisture that lasts more than a few days (e.g., cable in standing water). The applicant also stated that significant voltage exposure is defined as being subject to system voltage for more than 25 percent of the time.During its review, the staff noted that recently identified industry operating experience has shown that the presence of water or moisture can be a contributing factor in inaccessible power cable failures at lower service voltages (480 volts (V) to 2 kilovolts (kV)). The applicant has provided a commitment to expand the scope of the Inaccessible Medium Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program to include cables at lower service voltages (480 V to 2 kV) and to eliminate the exclusion of cables not subject to system voltage for more than 25 percent of the time. The staff and the applicant have reached an agreement regarding the applicant's proposed frequency for manhole inspections and cable testing. However, the staff has not received the applicant's commitment at this time. This issue remains a confirmatory item CI 3.0.3.1.20-1.
PSEG Response: PSEG Nuclear provided its commitment to shorten the maximum frequencies for manhole inspections and cable testing under its Inaccessible Medium Voltage Cables Not Subject to 10 CFR 50.49 Environmental Qualification Requirements Program in PSEG letter LR-N10-0360, dated September 30, 2010. PSEG believes that the information provided in that letter constitutes sufficient information for the NRC staff to close Confirmatory Item Cl 3.0.3.1.20-1.

Paragraph should be revised as follows: "As a result of its review of the LRA, including additional information submitted through September 21, 2010, the staff identified oe two confirmatory items (Cls). An item is considered confirmatory if the staff and the applicant have reached a satisfactory resolution but the applicant has not yet formally submitted the resolution.
The staff has assigned a unique identifying number to the each Cl." 5 2.1.4.1 2-9 Page 2-9, first paragraph, Exposure Limits section, sixth line revise as follows so statement agrees with UFSAR. "The exposure limit requirements in 10 CFR 50.34(a)(1) and 10 GFR 50.67(b)(2) is not applicable to HCGS license renewal." The very next sentence states"The UFSAR refers to both 10 CFR 50.67 and 10 CFR 100 for accident exposure limits."

SER states"The applicant stated that it has performed flaw evaluations for previously identified indications which are discussed in LRA Section 4.3." HC LRA Page C-9 states "Hope Creek has not performed flaw evaluations for found indications in accordance with subsection IWB-3600 of ASME Section Xl for the 40-year life of the plant.Therefore there are no indications that require re-evaluation for the period of extended operation." 14 3.0.3.1.10 3-36 Page 3-36, third line suggest revising as follows to better align with the program description in the LRA: "The applicant also stated that this program includes 4eque~t periodic leak testing of valves, piping, and other system components, espeGially those construc-ted Of carbon and stainless steel;and preventive monitoring that checks air quality at multiple locations in the system to ensure that oil, water, rust, dirt, and other contaminants are kept within accepted limits." 15 3.0.3.1.20 3-54 Page 3-54, concerning Section 3.0.3.1.20, based on responses to RAI's B.2.1.37-1, B.2.1.37-2, and information provided in the LRA supplement dated September 7, 2010, and pending resolution of confirmatory item Cl 3.0.3.1.20-1, the E3 Program has been enhanced to include 480 volt power cables and reduced the maximum testing and inspection frequencies.
This enhanced program should be in SER section 3.0.3.2, AMPs That Are Consistent with the GALL Report with Exceptions or Enhancements.

The aging effect/aging mechanism for the AMR line items in the mechanical systems (except for fuel handling and storage and cranes & hoists) associated with 3.3.1-45 is loss of preload due to thermal effects, gasket creep and self loosening.
34 3.3.2.1.4 3-301 Page 3-301, fourth paragraph needs clarification based upon LRA Table 3.3.2-10 in that the paragraph states that the LRA credits the Fire Protection program to manage aging of carbon steel doors and halon gas bottles and that a generic E note and plant-specific note 1 are cited. Plant-specific note 1 states that the Fire Protection AMP is substituted for the External Surfaces Monitoring AMP recommended by GALL for the "Doors" component type, however, the "Gas Bottles (Halon)" component type cites plant-specific note 15. Plant-specific note 15 states that the Fire Protection AMP will be used in addition to the External Surfaces Monitoring AMP recommended by GALL.35 3.3.2.2.5.1 3-316 & 3-317 Page 3-316, last paragraph and Page 3-317, fourth paragraph discuss and evaluate how the Structures Monitoring program will be used to manage Hardening and Loss of Strength Due to Elastomer Degradation for the inflatable pool seals in the Reactor Building.
Response to RAI 3.5.2.2.5.2 provided information that these pool seals are not subject to AMR and revised the LRA as such. Based on the RAI response the Structures Monitoring AMP does not manage aging of the inflatable pool seals in the Reactor Building.
