ENTERGY OPERATIONS,INC RIVER BEND STATION, UNIT 1 DOCKET NUMBER 50 458 CML ENGINEERING AND GEOSCIENCES BRANCH DIVISION OF ENGINEERING Reouest for Additional Information (RAl) on the second 10-Year Interval inservice Reauests for BRhtf.

A. Scone / Status of Revjag Throughout the service life of a water-cooled nuclear power facility,10 CFR 50.55a(g)(4) requires that components (including supports) that are classified as American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Class 1, Class 2, and Class 3 meet the requirements, except design and access provisions and preservice examination requirements, set forth in the ASME Code,Section XI, " Rules for Inservice Inspection of Nuclear Power Plant Components," to the extent practical within the limitations of design, geometry, and materials of construction of the components. This section of the regulations also requires that inservice examinations of components and system pressure tests conducted during successive 120-month inspection intervals comply with the requirements in the latest edition and addenda of the Code incorporated i by reference in 10 CFR 50.55a(b) on the date 12 months prior to the start of the interval, f subject to the limitations and modifications listed therein. The components (including supports) may meet examination requirements set forth in subsequent editions and addenda of the Code that are incorporated by reference in 10 CFR 50.55a(b) subject to the limitations and modifications listed therein and subject to Nuclear Regulatory Commission (NRC) approval. The licensee, Entergy Operations, Inc, prepared the second ISI interval program plan to meet the requirements of the 1992 Edition of the ASME Code Section XI. The second 10-year interval began December 1,1997.

As required by 10 CFR 50.55a(g)(5), if the licensee determines that certain Code examination requirements are impractical and requests relief, the licensee shall submit information to the NRC to support that determination.

The staff has reviewed the available information in thesecond ISI interval Relief Requests RR2-0001 througn RR2-0003, submitted January 7,1998. Based on this l

ENCLOSURE l

a review, the staff has concluded that the information and/or clarification described in the next section is required to complete the review. ,

B. Additional Information Reauired Request for Relief RR2-0003 seeks relief from the surface examination requirements for specific Class 2 pump casing welds that are encased in concrete for the second ISI interval. The licensee is proposing to examine the subject welds only if the pump is disassembled for maintenance. However, during the first ISl interval, a relief request was submitted for the same pump casing welds. In the first interval request, an attemative was proposed to include examinations of the accessible portion of the pump casing welds (examination coverage was as high as 80% in some cases). Explain why accessible portions of the subject pump casing welds are not receiving a surface examination during the second interval. Describe the limitations in detail. In addition, explain how the weld numbering convention used during the first interval corresponds to the welds identified in the second interval relief request. How do the welds identified in RR2-0003 correspond with the weld numbers on the attached Figure 1, " Typical Pump Configuration"? Discuss why the total number of welds for which relief is requested is not the same in the first interval request as in the second interval for each of the subject pumps.

i The schedule for timely completion of this review requires that the licensee provides, by the requested date, the above requested information and/or clarifications regarding the second ISl interval relief requests RR2-0001 through RR2-0003.
