SUMMARY

OF TELEPHONE CONFERENCE CALL ENTERGY OPERATIONS, INC.

LICENSE RENEWAL APPLICATION NOVEMBER 30, 2016 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of Entergy Operations, Inc. (Entergy or the applicant) held a telephone conference call on November 30, 2016, to discuss and clarify the staffs draft requests for additional information draft (RAIs) concerning the Waterford Steam Electric Station, Unit 3, license renewal application (LRA). Draft RAI Set 9 contained draft RAIs 3.3.1-1a, 3.3.1-2a, B.1.17-02, B.1.21-1, and 1.13 -3d(a). Draft RAIs 3.3.1-2a, B.1.21-1, and 1.13-3d(a) were not discussed and draft RAI B.1.17-02 was previously issued and therefore was deleted from this RAI set. Draft RAI 3.3.1 1a was discussed and revised to clarify the staffs questions. The staff determined that requests 2 through 4 in the draft RAI were not needed and deleted these requests. Draft RAI 3.3.1-2a with the deleted request is given below. The deleted portion of the RAI has been crossed out. Final versions of these RAIs will be formally issued as final RAIs to the applicant.

RAI 3.3.1-2a

Background:

The response to RAI 3.3.1-1 (FWS AMR-1), dated November 10, 2016 (Agencywide Document Access and Management System Accession No. ML16315A235), states that the makeup source for the fire water system is the potable water system. The response also states that consistent with Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants Table 3.3-1, item 3.3.1-93, copper alloy piping exposed to raw water (potable) is not susceptible to general corrosion.

LRA Section 2.3.3.8, Treated Water, states, [t]he treated water system is no longer used for processing raw water from the Mississippi River. The treated water system has been inactivated except for the clearwell tank, clearwell transfer pumps, bearing lubrication water pumps for the circulating water pumps, and associated piping, valves, instrumentation, and controls.

LRA Section 2.3.3.15, Auxiliary Systems in Scope for 10 CFR [Code of Federal Regulations] 54.4(a)(2) - Potable Water, states, [t]he purpose of the potable water system is to distribute water from the St. Charles Parish Water System throughout the plant site. The system provides potable water, both hot and cold, for drinking water, sanitary services, and emergency showers and eyewash stations. The distribution system also supplies makeup water to the fire water storage tanks and to the primary water treatment plant clearwell tank.

Updated final safety analysis report (UFSAR) Section 9.5.1.2.2 (b) states, [t]he makeup water supply to the water storage [fire water] tanks is capable of filling either tank within an 8-hour period. The tanks are filled directly from the potable water system or by pumps drawing suction ENCLOSURE 2

from the Primary Water Treatment System clear well, which is supplied with either filtered Mississippi River water or Parish water.

Issue:

The staff has concluded that copper alloy components exposed to raw water (potable) are not susceptible to general corrosion. However, it appears that there is a conflict between statements in the LRA and the UFSAR. Based on the UFSAR references cited above, it is not clear whether the fire water system components will be exposed to raw water or raw water (potable). Filtered Mississippi River water would be considered raw water because it is assumed that the filtering process would not remove adverse chemical species (i.e., the water purity is not enhanced beyond removing sediment).

Based on the text in the LRA and UFSAR, it is not clear to the staff whether the LRA is correct and the UFSAR is out of date or there is some other interpretation of the wording, which is supplied with either filtered Mississippi River water or Parish water. The staff is concerned that with the wording in the current licensing basis (i.e., UFSAR Section 9.5.1.2.2 (b)), filtered Mississippi River water could become a normal source of makeup for the fire water system. If the LRA is correct and the UFSAR is out of date, it is not apparent that either the modification or UFSAR change process would direct the engineering staff to address loss of material due to general corrosion if the source of makeup for the fire water system were to become filtered Mississippi River water.

Request:

1. Clarify whether UFSAR Section 9.5.1.2.2 (b) is stating that filtered Mississippi River water could be a normal source of makeup for the fire water system. If UFSAR Section 9.5.1.2.2 (b) is in error or out of date, state whether the condition has been documented in the corrective action program.

2. If filtered Mississippi River water could be a normal source of makeup for the fire water system, state the basis for why it would be considered raw water (potable) in lieu of raw water or revise the associated Table 2 line items to state that loss of material due to general corrosion will be managed.

3. If loss of material due to general corrosion will be managed, respond to the original RAI request, [s]tate and justify the method that will be used in the Fire Water System program to detect loss of material due to general corrosion in copper alloy tubes exposed to raw water.

4. If it is not the intent of the current licensing basis (i.e., UFSAR Section 9.5.1.2.2 (b)) that filtered Mississippi River water could be a normal source of makeup for the fire water system, state what specific processes are in place that would result in loss of material due to general corrosion being addressed if filtered Mississippi River water would become a normal source of makeup for the fire water system.
