ENCLOSURE 2 COOPER NUCLEAR STATION POWER PLANT LICENSE RENEWAL APPLICATION (Brief description of the conference call)

The U.S. Nuclear Regulatory Commission staff and representatives of Nebraska Public Power District (NPPD), held a telephone conference call on May 20, 2009, to discuss clarifications for certain draft requests for additional information listed below.

Discussion

RAI B.1.15-9 (Draft)

Based on the conference call between the staff and the applicant on May 20, 2009, RAI B.1.15-3 (ML091240344) was updated as follows:

Background

Program Element 4 of NUREG-1801 Section X.M1 is concerning detection of aging effects. Under the Cooper Nuclear Station (CNS) Fatigue Monitoring Program, B.1.15 (CNS-RPT-LRD02, Revision 1), program element 4 subsection b states: "No actions are taken as part of this program to detect aging effects-If a design cycle assumption is approached, corrective action is taken which will include update of fatigue usage calculation, if necessary."

In addition, Program Element 5 of NUREG-1801 Section X.M1 is concerning monitoring and trending. Under the CNS Fatigue Monitoring Program, B.1.15 (CNS-RPT-LRD02, Revision 1),

Program Element 5, Subsection B, it states: "The Fatigue Monitoring Program monitors the number of pressure and temperature transient cycles and periodically compares this cycle count with the design cycle count to ensure that fatigue sensitive components remain within their allowable design-"

Issue Clarification is deemed necessary, as described below. Additionally, Element 5 indicates that

only the feedwater nozzle will be monitored.

Request (a) Please provide the basis for why taking "no action" will achieve the goal of detecting aging effects. (b) Please explain why "design cycle" can be used as a basis for detecting aging effects when the design transients do not include all thermal events actually experienced by the reactor coolant pressure boundary components, as discussed in RAI B.1.15-2. (c) The license renewal application (LRA) states that the environmental fatigue analyses were performed based on the 60-year projected cycles and LRA Table 4.3-1 shows that the 60-year projected cycles for most of the transients are less than the design cycles. With these conditions in mind, components could have failed before the design cycles are approached. Provide justification that the design cycles can be used as criteria to detect aging effects. (d) "Generic Aging Lessons Learned (GALL) report," requires all high fatigue locations are monitored, not just at the most limiting location within the applicable NUREG/CR-6260 locations, as minimum. Please provide justification that CNS will monitor the feedwater nozzle only. The applicant indicated understanding of this request for information.

RAI B.1.15-10 (Draft)

Based on the conference call between the staff and the applicant on May 20, 2009, RAI B.1.15-4 (ML091240344) was updated as follow:

Background

Program Element 6 of NUREG-1801 Section X.M1 is concerning acceptance criteria. Under the CNS Fatigue Monitoring Program, B.1.15 (CNS-RPT-LRD02, Revision 1), Program Element 6 Subsection B states: "The Fatigue Monitoring Program acceptance criteria are that none of the transients exceeded the allowable numbers in USAR Table III-3-1-"

Issue Clarification is deemed necessary, as described below:

Request (a) Questions (b) and (c) of RAI B.1.15-3 apply here. Please explain accordingly. (b) GALL Section X.M1 Element 6 requires maintaining fatigue usage below the design code limit considering environmental fatigue effects. CNS Fatigue Monitoring Program, Element 6 does not mention environmental fatigue effects. Please explain why. The applicant indicated understanding of this request for information.
