BEAVER VALLEY POWER STATION (BVPS), UNITS 1 AND 2 LICENSE RENEWAL APPLICATION (LRA)

REQUEST FOR ADDITIONAL INFORMATION (RAI)

SECTION 2.1 Section 2.1 RAI 2.1-1 10 CFR 54.4(a)(1)(iii) requires that plant systems, structure, and component (SSC) within the scope of license renewal (LR) include safety-related SSCs, which are those relied upon to remain functional during and following design-basis events (as defined in 10 CFR 50.49(b)(1))

to ensure the capability to prevent or mitigate the consequences of accidents that could result in potential offsite exposure comparable to the guidelines in 10 CFR 50.34(a)(1), 10 CFR 50.67(b)(2), or 10 CFR 100.11, as applicable.

During the scoping and screening methodology audit, performed at the facility December 3-6, 2007, the staff noted the definitions of safety-related used to identify SSCs within the scope of LR as contained in the License Renewal Application (LRA). The LR scoping procedures and the text of the plant classification document agree with the definition contained in 10 CFR Part 54.4(a)(1)(iii). However, the form/procedure used to initially populate the equipment data base, and subsequently relied upon to identify safety-related SSCs, refers only to 10 CFR Part 100.

Units 1 and 2 have been approved for use of the alternate source term and, therefore, 10 CFR 50.67(b)(2) is applicable. This issue applies to BVPS Units 1 and 2.

The staff requests that the applicant provide a written evaluation that addresses the impact, if any, of (1) the use of a differing definition of safety-related, and of (2) not having explicitly considered in its scoping methodology for BVPS those structures, systems, or components that are relied upon to ensure the capability to prevent or mitigate the consequences of accidents that could result in potential offsite exposures comparable to the guidelines in 10 CFR 50.34(a)(1),10 CFR 50.67(b)(2), or 10 CFR 100.11 of this chapter, as applicable, consistent with the CLB.

RAI 2.1-2 The LRA states that the application was developed in accordance with the guidance of NEI 95-10, Revision 6, which the NRC has endorsed via Regulatory Guide 1.188. NEI 95-10 contains a definition of equivalent anchor, which includes a combination of restraints or supports such that the nonsafety-related piping and associated structures and components attached to safety-related SSCs are included in scope up to a boundary point that encompasses of at least two supports in each of three orthogonal directions. Equivalent anchors are one method used to define the portion of nonsafety-related pipe, attached to safety-related SSCs, to be included within the scope of LR in accordance with 10 CFR 54.4(a)(2).

During the NRC scoping and screening methodology audit, performed at the facility December 3-6, 2007, the applicant indicated that equivalent anchors had been used to identify portions of nonsafety-related pipe to be included within the scope of LR. However, the applicant indicated that in certain cases, combinations of less than two restraints or supports in each of the three orthogonal directions had been used as equivalent anchors to determine the portions

of nonsafety-related pipe, attached to safety-related SSCs, to be included within the scope of LR. This issue applies to BVPS Units 1 and 2.

The staff requests that the applicant provide a written evaluation to address your review of this issue. Indicate if the review concludes that use of the scoping methodology precluded the identification of nonsafety-related SSCs that could interact with safety-related SSCs, and which were not specifically exempted by your current licensing basis (CLB), and therefore should have been considered within the scope of LR. Describe any additional scoping evaluations to be performed to address the 10 CFR 54.4(a)(2) criteria.

As part of your response, please address the extent of condition (the number and location of equivalent anchors which contained less than two supports in each of the three orthogonal directions). List any additional SSCs included within the scope as a result of your efforts, and list those structures and components for which aging management reviews were conducted. For each structure and component, describe the aging management programs, as applicable, to be credited for managing the identified aging effects.

RAI 2.1-3 The Beaver Valley Power Station (BVPS) LRA states that the limits of the NRC Office of Inspection and Enforcement Bulletin (IEB) 79-14, Seismic Analyses for As-built Safety-Related Piping Systems, evaluations as shown on isometric or other controlled engineering drawings,were used to identify the portions of nonsafety-related piping, attached to safety-related SSCs, to be included within the scope of LR in accordance with the requirements of 10 CFR 54.4(a)(2).

The staff requests that the applicant provide a discussion to specifically address how the information obtained in the walk-downs previously performed in support of IEB 79-14 was used to identify either a seismic anchor or an equivalent anchor, as defined in Appendix F of NEI 95-10, Revision 6, in order to determine the portion of the nonsafety-related pipe to be included within the scope of LR in accordance with 10 CFR 54.4(a)(2). This issue applies to BVPS, Units 1 and 2.

The staff requests that the applicant provide a written evaluation to address the review of this issue. Indicate if the review concludes that use of the scoping methodology precluded the identification of nonsafety-related SSCs that could interact with safety-related SSCs, and which were not specifically exempted by your CLB, and therefore should have been considered within the scope of LR. Describe any additional scoping evaluations to be performed to address the 0 CFR 54.4(a)(2) criteria.

As part of your response, list any additional SSCs included within the scope as a result of your efforts, and list those structures and components for which aging management reviews were conducted. For each structure and component, describe the aging management programs, as applicable, to be credited for managing the identified aging effects.

RAI 2.1-4 The applicant identified certain components classified as Q (a BVPS term used to identify safety-related components) which are located within the nonsafety-related turbine building.

However, the identified Q components were not included within the scope of LR in accordance with 10 CFR 54.4(a)(1). In addition, neither the turbine building nor the nonsafety-related SSCs in the vicinity of the Q components were included within the scope of LR in accordance with 10 CFR 54.4 (a)(1) or (a)(2) as applicable. This issue applies to BVPS, Units 1 and 2.

The staff requests that the applicant provide a written evaluation to address your review of this issue. Indicate if the review concludes that use of the scoping methodology precluded: (1) the identification of safety-related SSCs which should have included within the scope of LR in accordance with 10 CFR 54.4(a)(1), and (2) the identification of nonsafety-related SSCs that could interact with safety-related SSCs, and which were not specifically exempted by your CLB, and therefore should have been considered within the scope of LR in accordance with 10 CFR 54.4(a)(2). Describe any additional scoping evaluations to be performed to address the 10 CFR 54.4(a)(1) and (a)(2) criteria.

As part of your response, list any additional SSCs included within the scope as a result of your efforts, and list those structures and components for which aging management reviews were conducted. For each structure and component, describe the aging management programs, as applicable, to be credited for managing the identified aging effects.

RAI 2.1-5 (A) A safety-related portion of the Unit 1 river water pipe, which consists of pipe and an elastic expansion joint, was included within the scope of LR in accordance with 10 CFR 54.4(a)(1).

This portion of the river water pipe exits from the safety-related main steam cable vault pipe tunnel (included within the scope of LR in accordance with 10 CFR 54.4(a)(1)) and enters the nonsafety-related turbine building. However, neither the turbine building, nor the nonsafety-related SSCs located in the turbine building and in the vicinity of the river water pipe, have been included within the scope of LR in accordance with 10 CFR 54.4(a)(1) or (a)(2) as applicable. In addition, the river water pipe supports located the turbine building, which provide structural support to the safety-related river water pipe, were not included within the scope of LR.

(B) The turbine building is contiguous with the main steam cable vault pipe tunnel with no wall or door providing separation between the interiors of the two structures. The main steam cable vault pipe tunnel is safety-related and contains safety-related SSCs, all of which are included within the scope of LR in accordance with 10 CFR 54.4(a)(1). However, neither the turbine building, nor the nonsafety-related SSCs located in the turbine building and in the vicinity of the opening to the main steam cable vault pipe tunnel, have been included within the scope of LR in accordance with 10 CFR 54.4(a)(2).

(C) The turbine building is adjacent to the safety-related service building which was included within the scope of LR in accordance with 10 CFR 54.4(a)(1). However, the turbine building, although directly adjacent to a safety-related structure, has not been included within the scope of LR in accordance with 10 CFR 54.4(a)(2). These issues apply to BVPS Units 1. The staff requests that the applicant provide a written evaluation to address your review of these issues.

Indicate if the review concludes that use of the scoping methodology precluded: (1) the identification of safety-related SSCs which should have included within the scope of LR in accordance with 10 CFR 54.4(a)(1), and (2) the identification of nonsafety-related SSCs that could interact with safety-related SSCs, and which were not specifically exempted by your CLB, and therefore should have been considered within the scope of LR in accordance with 10 CFR 54.4(a)(2). Describe any additional scoping evaluations to be performed to address the 10 CFR 54.4(a)(1) and (a)(2) criteria.

As part of your response, list any additional SSCs included within the scope as a result of your efforts, and list those structures and components for which aging management reviews were conducted. For each structure and component, describe the aging management programs, as applicable, to be credited for managing the identified aging effects.
