SUMMARY

OF CONFERENCE CALL DISCUSSION FERMI 2 NUCLEAR POWER PLANT LICENSE RENEWAL APPLICATION September 16, 2014 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of DTE Electric Company held a telephone conference call on September 16, 2014, to discuss and clarify the following draft request for additional information (D-RAI) concerning the license renewal application (LRA).

D-RAI 2.1-1

Background:

10 CFR 54.4, Scope, states, in part:

(a) Plant systems, structures and components [SSCs] within the scope of this part are -

(1) Safety-related systems, structures, and components 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 following functions - (i) the integrity of the reactor coolant pressure boundary; (ii) the capability to shut down the reactor and maintain it in a safe shutdown condition; or (iii) the capability to prevent or mitigate the consequences of accidents which could result in potential offsite exposures comparable to those referred to in 10 CFR 50.34(a)(1), 10 CFR 50.67(b)(2), or 10 CFR 100.11, as applicable.

(2) All nonsafety-related systems, structures and components whose failure could prevent satisfactory accomplishment of any of the functions identified in (a)(1)(i), (ii), or (iii) of this section.

LRA Section 2.1.1.2.2(1), Nonsafety-Related SSCs Directly Connected to Safety-Related SSCs, states that nonsafety-related SSCs attached to safety-related SCs [structures and components] are in the scope of license renewal in accordance with 10 CFR 54.4(a)(2) up to the first seismic (or equivalent) anchor or alternative bounding criteria, past the safety-related/

nonsafety-related interface.

LRA Section 2.1.1.2.2(2)(c), Spray or Leakage, states that nonsafety-related SSCs with the potential for spray or leakage that could prevent safety-related SSCs from performing their required safety function are within the scope of license renewal in accordance with the requirements of 10 CFR 54.4(a)(2) and is that portion of the nonsafety-related SSC contained in the same space as the safety-related SSC.

Issue:

During the on-site scoping and screening methodology audit the staff reviewed the implementing document used by the applicants staff to identify nonsafety-related SSCs with the potential to affect safety-related SSCs, for inclusion within the scope of license renewal. The applicants implementing document stated that only nonsafety-related SSCs that had not been included within the scope of license renewal based on the potential for spray or leakage needed to be reviewed for nonsafety-related SSCs directly attached to safety-related SSCs to identify the portion of the nonsafety-related SSC up to the first anchor, equivalent anchor or bounding condition, past the safety-related/nonsafety-related interface.

During the audit the applicant stated that the implementing document had been followed and that fluid-filled, nonsafety-related SSCs located within the same space as safety-related SSCs, were included within the scope of license renewal. However, for fluid-filled nonsafety-related SSCs that were also attached to safety-related SSCs, the applicant had not identified the portion of the nonsafety-related SSC past the safety-related/nonsafety-related interface to be included within the scope of license renewal, up to and including an anchor, equivalent anchor or bounding condition.

Request:

The staff requests that the applicant provide a basis for not including the portion of nonsafety-related SSCs attached to safety-related SSCs up to and including an anchor, equivalent anchor or bounding condition, within the scope of license renewal in accordance with 10 CFR 54.4(a)(2).

Discussion:

The staff provided clarification related to its concern in draft RAI 2.1-1 and stated it will revise the draft RAI to more accurately explain the actions taken by the applicant when identifying the SSCs to be included within the scope of license renewal.
