REQUEST FOR ADDITIONAL INFORMATION APPLICATION TO REVISE TECHNICAL SPECIFICATIONS TO ADOPT TSTF-542, REVISION 2 REACTOR PRESSURE VESSEL WATER INVENTORY CONTROL NEBRASKA PUBLIC POWER DISTRICT COOPER NUCLEAR STATION DOCKET NO. 50-298 By application dated August 7, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17228A042, Nebraska Public Power District (the licensee) requested to adopt Technical Specifications Task Force (TSTF) Traveler TSTF-542, "Reactor Pressure Vessel Water Inventory Control," Revision 2, which changes the Technical Specifications (TSs) for Cooper Nuclear Station (CNS). Traveler TSTF-542, Revision 2, was approved by the U.S. Nuclear Regulatory Commission (NRC) on December 20, 2016 (ADAMS Accession No. ML16343B008).

CNS TS Section 2.0, "Safety Limits," paragraph 2.1.1.3 states, "Reactor vessel water level shall be greater than the top of active irradiated fuel." Safety Limit 2.1.1.3 is maintained through the TS Limiting Condition for Operation (LCO) applicability, actions, and notes. The CNS TSs require certain safety systems to be OPERABLE during "operations with a potential for draining the reactor vessel" (OPDRVs). The proposed changes would replace existing TS requirements associated to OPDRVs with revised TSs providing an alternative requirement for Reactor Pressure Vessel (RPV) Water Inventory Control (WIC). These alternative requirements would protect Safety Limit 2.1.1.3. The NRC staff has reviewed the proposed amendment and has determined that additional information is needed to complete its review. CNS RAI-1 The licensee's TS mark-up, page 3.3-47 (proposed new LCO 3.3.5.3, Required Action B.1) states: Declare supported penetration flow path(s) incapable of automatic isolation. [underline added] TSTF-542, Revision 2, LCO 3.3.5.2, Required Action B.1 states:

Declare associated penetration flow path(s) incapable of automatic isolation. [underline added] Please justify the difference between the proposed LCO and the TSTF in a variation.

2 CNS RAI-2 The licensee's TS mark-up, page 3.5-10 (proposed new SR 3.5.2.5), is not labeled correctly, as existing SR 3.5.2.5 is crossed out, and no new SR 3.5.2.5 "identification box" appears near the new text for SR 3.5.2.5.

Please correct the SR 3.5.2.5 "identification box" or explain that the licensee's proposed markup of SR 3.5.2.5 is correct, as shown.
