ENCLOSURE 2 COOPER NUCLEAR STATION POWER PLANT LICENSE RENEWAL APPLICATION (Brief description of the conference call)
The U.S. Nuclear Regulatory Commission (NRC) staff and representatives of Nebraska Public Power District, held a telephone conference call on July 9, 2009, to discuss clarifications for certain draft requests for additional information (RAI) listed below.
A. Clarification on draft RAI RAI B.1.40-4 (Draft)
=
Background===
License Renewal Application (LRA) Section B.1.40 states the chemistry activities for this program are based on Electric Power Research Institute (EPRI) TR-1007820, Closed Cycle Cooling Water Chemistry, Revision 1, dated April 2004, which supersedes EPRI TR-107396, Closed Cycle Cooling Water Chemistry Guideline, Revision 0, issued November 1997.
Generic Aging Lessons Learned (GALL) Aging Management Program (AMP) XI.M21, Closed-Cycle Cooling Water System, states that it relies on maintenance of system corrosion inhibitor concentrations within the specified limits of EPRI TR-107396 to minimize corrosion and stress-corrosion cracking.
Issue The GALL Report does not recommend the use of late revisions of EPRI TR-107396. The applicants program is implemented using the later revision, EPRI TR-1007820, rather than the edition referenced in the GALL Report, EPRI TR-107396. The staff noted the use of EPRI TR-1007820 may potentially impact the program elements, Preventative Actions and Acceptance Criteria of the applicants program, since the corresponding program elements in the GALL Report reference the limits on corrosion inhibitor concentrations specified in EPRI TR-107396.
Request Justify this deviation from the GALL Report and discuss its impact on the program elements, Preventative Actions and Acceptance Criteria, with reference to limits on specific corrosion inhibitor levels, monitoring frequencies, and operating parameters.
The applicant indicated understanding of this RAI.
B. Clarification on response to RAI RAI 3.3.1-1 Regarding RAI 3.3.1-1, which was issued to the applicant on May 1, 2009 (ML091240344) and responded by the applicant on June 15, 2009 (ML091690050), the staff asked for further clarification on the implementation of the criteria for discontinuation of the reactor water cleanup system outboard piping inspections. The staff requested the following clarifications and associated available documentation:
(1) For the inboard piping and piping welds, please clarify on the inter-granular stress corrosion cracking (IGSCC) resistant materials used.
(2) Has IGSCC been detected after the foregoing inboard piping replacement?
(3) For the outboard piping (reference: letter from G.A. Trevors to the NRC, Generic Letter 88-01, Cooper Nuclear Station, October 9, 1990), what examination method was used to detect the flaw? What is the technical basis that justifies that the flaw is not IGSCC?
The applicant provided the following clarifications:
(1) The piping material was SS 316NG, which is an IGSCC-resistant material. The weld material was SS 308L with a minimum of 5 FN and max of 10FN to control delta ferrite, and the heat input was controlled. In addition, the welds received induction heating stress improvement to reduce the residual stress. The combination of the weld material and IHSI meets the requirements of NUREG 0313 Rev 1 and GL 88-01 to be qualified for providing resistance to IGSCC in new or replacement boiling water reactor piping welds.
(2) No, IGSCC was not detected from the inboard piping after the replacement. The determinations were provided by qualified examiner(s).
(3) The applicant agreed to take action to recover detailed examination information to confirm the nature of the flaw-defection from 1990 inspection to support closing of the third question. This will be provided in a subsequent response to RAI letter as supplemental information to RAI 3.3.1-1.
