SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3, LICENSE RENEWAL APPLICATION
Dear Mr. McCollum:
By letter dated July 6, 1998, Duke Energy Corporation (Duke) submitted for the Nuclear Regulatory Commission's (NRC's) review an application pursuant to 10 CFR Part 54, to renew the operating licenses for the Oconee Nuclear Station (Oconee), Units 1, 2, and 3. Exhibit A to the application is the Oconee Nuclear Station License Renewal Technical Information Report (OLRP-1001), which contains the technical information required by 10 CFR Part 54. The NRC staff is reviewing the information contained in OLRP-1001 and has identified, in the enclosure, areas where additional information is needed to complete its review. Specifically, the enclosed questions are from the Plant Systems Branch regarding OLRP-1001 Section 4.16.
Please provide a schedule by letter, electronic mail, or telephonically for the submittal of your responses within 30 days of the receipt of this letter. Additionally, the staff would be willing to meet with Duke prior to the submittal of the responses to provide clarifications of the staffs requests for additional information.

REQUEST FOR ADDITIONAL INFORMATION OCONEE NUCLEAR STATION. UNITS 1. 2. AND 3 LICENSE RENEWAL APPLICATION. EXHIBIT A OLRP-1001 Section No.
4.16 Fire Protection Program 4.16-1 Section 3.7.2.4 defined aging effects for fire walls, fire doors, and fire barrier penetration seals. Describe the scope of the fire barrier inspections included in Section 4.16.1 and explain how they will be used to manage the aging effects of the fire barriers (e.g.,
cracking and separation of penetration seals located beneath damming boards).
Describe which material properties of fire barrier and penetration seal materials will be reviewed and assessed during these inspections. Describe the methods that will be used to detect aging effects prior to an observed failure.
4.16-2 For materials such as silicone elastomer and silicone foam, provide an analysis or industry data that addresses whether or not these materials are subject to age-related degradation in their installed configurations and locations or exhibit appreciable degradation over time.
4.16-3 Provide a list of surveillance, maintenance, and inspection procedures that are credited with managing the effects of aging for the fire protection systems listed in Section 4.16.
Provide a demonstration of how the procedures manage aging effects for fire protection piping and fire barriers.
4.16-4 Provide a list of all materials used for fire protection including those used for fire protection barriers and describe the aging effects specifically associated with each of the material types.
4.16-5 The application states that raw water is used in the fire protection system. Please clarify the source for the raw water (i.e., well water vs river water). Also, discuss the general chemistry of the raw water and the potential aging degradation and associated effects that could occur based on the chemistry of the water.
Note: Question 4.16-6 was issued to Duke in a December 3, 1998 letter.
4.16-7 Describe any special treatment used to control corrosion of the fire protection piping.
Include in your discussion, the use of inhibitors, biocides, or other chemical additions, and describe when and how they are used. For instance, what actions are taken for layed-up lines or low flow lines? Summarize the procedures for testing these lines, and the actions taken after testing these lines.
