SUMMARY

OF TELEPHONE CONFERENCE CALL FERMI 2 LICENSE RENEWAL APPLICATION February 9, 2015 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of DTE Electric Company (DTE or the applicant) held a telephone conference call on February 9, 2015, to discuss and clarify the following draft request for additional information (DRAI) concerning the Fermi 2 license renewal application (LRA).

DRAI B.1.19-8a

Background:

One of the plant-specific operating experience examples cited in the license renewal application (LRA) describes fire suppression flow testing that demonstrated degrading conditions in the underground piping system. The LRA states that the frequency of testing and evaluation of this piping has been increased from 3 years, as required in the current licensing basis, to annual testing.

The response to RAI B.1.19-8, dated January 15, 2015, states an enhancement to the LRA Section B.1.19 corrective action program element. The enhancement states, [r]evise Fire Water System Program procedures to consider in accordance with the Corrective Action Program increasing test frequency if there is a decreasing trend in flow in the fire water system flow test.

Issue:

The staff recognizes that if an adverse trend in system performance is detected during the period of extended operation, the condition adverse to quality will be evaluated in accordance with the Corrective Action Program. However, given the existing degraded condition, the staff lacks sufficient information to:

• Find the enhancement acceptable because the use of the term consider leaves it indeterminate whether the frequency of fire water system flow testing will be increased during the period of extended operation if the current decreasing trend in system performance reveals that the system may not be capable of performing its intended function throughout the period of extended operation.

• Conclude that existing corrective actions will be sufficient to correct the adverse trend prior to the period of extended operation.

Therefore, the staff cannot conclude that plant-specific operating experience associated with flow testing of the underground fire water system has been adequately evaluated.

ENCLOSURE 2

Request:

State and justify the basis for why the current trend in fire water system performance will be corrected prior to the period of extended operation, or state a commitment to continue the increased frequency of fire water system flow tests until such time as trend data demonstrates that the system will be capable of performing its intended function throughout the period of extended operation.

Discussion:

The staff provided clarification related to its request in draft RAI B.1.19-8a and stated it will revise the request as follows:

State and justify the basis for why the current trend in fire water system performance will be corrected prior to the period of extended operation, or state a commitment to continue the increased frequency of fire water system flow tests until such time as the current trend data demonstrates that the system will be capable of performing its intended function throughout the period of extended operation.

The applicant understands the staffs concerns and will provide a response to the draft RAI.

The RAI will be issued as revised.
