NRC STAFF REBUTTAL TESTIMONY OF RICHARD A. PLASSE CONCERNING AGING MANAGEMENT PROGRAMS Q1. Please state your name, occupation, and by whom you are employed.

A1. My name is Richard A. Plasse (Plasse). I am employed as a project manager in the Nuclear Regulatory Commissions Office of Nuclear Reactor Regulation, Division of License Renewal. A statement of my professional qualifications is attached to my July 30, 2010 pre-filed testimony.

Q2. What is the purpose of your testimony?

A2. The purpose of my testimony is to respond to testimony and exhibits submitted by the Prairie Island Indian Community (PIIC) and Northern States Power Company (NSP or Applicant) on July 30, 2010.

Q3. In A18 and A31, Mr. Grimes testifies that the Applicants performance with respect to the leakage of borated water and the Applicants performance issues with respect to the White finding related to the design of the component cooling water system call into question the Applicants ability to implement aging management programs during the period of extended

operation. Why is Mr. Grimes reliance on these performance issues misplaced?

A3. Mr. Grimes reliance on these performance issues in the license renewal is misplaced. These issues are not addressed as part of the license renewal process. They are addressed by the Reactor Oversight Program. As I stated in my July 30, 2010 testimony at A17-18, the Staffs determination of the adequacy of AMPs presumes that if a license is issued, the licensee will implement the AMPs in accordance with its renewed licensing basis.

The Staff can presume this because Regional Staff will conduct a post-approval inspection in which it will sample aging management programs to check for implementation and Resident Inspectors and Regional Staff will routinely conduct inspections and assessments of compliance during the period of extended operation. Therefore, when it issues its Safety Evaluation Report, there is no need for the Staff to try to judge the Applicants ability to implement aging management programs.

Q4. In A22-23, Mr. Grimes testified that performance issues associated with NSPs mispositioning of a valve violate certain elements of an effective aging management program.

Do you agree?

A4. No. According to Mr. Grimes testimony and the document he referred to (Information Notice 2009-11, Configuration Control Errors,), the performance issues regarding the mispositioned valve included 1) the valve not being labeled, 2) the valve not being locked, and 3) procedures did not identify that the mispositioned valve should be locked. These performance issues are not relevant to whether or not NSPs AMPs effectively manage the effects of aging. Pursuant to NUREG-1800, Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants, Rev.1, dated September 2005 (NRC Staff Exhibit No. 4ANRC000006), the Staffs aging management review does not include a review of configuration control errors and these issues were not considered by the Staff in its evaluation

of NSPs aging management programs.
