Dear Sir or Madam:
On June 6, 2013, the Nuclear Regulatory Commission issued an Order (Reference
- 1) to Nebraska Public Power District (NPPD). Reference I was immediately effective and directs NPPD to install a reliable hardened venting capability at Cooper Nuclear Station (CNS) for pre-core damage and under severe accident conditions, including those involving a breach of the reactor vessel by molten core debris. Specific requirements are outlined in Attachment 2 of Reference 1.Reference I required submission of a Phase 1 Overall Integrated Plan (OIP) pursuant to Section IV, Condition D. Reference 2 endorses industry guidance document NEI 13-02, Revision 0 (Reference
- 3) with clarifications and exceptions identified in Reference
- 2. Reference 4 provided NPPD's initial OIP and Reference 5 provided a revised OIP for CNS.Reference 1 requires submission of a status report at six-month intervals following submittal of the OIP. Reference 3 provides direction regarding the content of the status reports. The purpose of this letter is to provide the second six-month status report pursuant to Section IV, Condition D, of Reference 1, that delineates progress made in implementing the requirements of Reference 1.The attachment provides an update of milestone accomplishments including any changes to the compliance method, schedule, or need for relief and the basis, if any.This letter contains no new regulatory commitments.
If you have any questions regarding this report, please contact Jim Shaw, Licensing Manager, at (402) 825-2788.I declare under penalty of perjury that the foregoing is true and correct.Executed on: (P o50 ISincere c .L~impias Vice President

Introduction Nebraska Public Power District (NPPD) developed an Overall Integrated Plan (OIP) (Reference
- 1) in accordance with the guidance contained in References 3 and 4. This OIP documents the installation of a Hardened Containment Vent System (HCVS) at Cooper Nuclear Station (CNS)that provides a reliable hardened venting capability for pre-core damage and under severe accident conditions, including those involving a breach of the reactor vessel by molten core debris, in response to Reference 2.As part of the first six-month status report, NPPD reported a change in the method of compliance with regard to the design of the wetwell vent due to increasing complexity of the design needed to support using existing underground piping. NPPD submitted a revised OIP with that status report (Reference 5).This attachment provides an update of milestone accomplishments including changes to the compliance method, schedule, or need for relief/relaxation and the basis, if any.Milestone Accomplishments The following milestone(s) have been completed since last status update and are current as of June 15, 2015:* None.Milestone Schedule Status The following table provides an update to the milestones contained in the OIP. It provides the activity status of each item, and whether the expected completion date has changed. The dates are planning dates subject to change as design and implementation details are developed.

Changes to Compliance Method None to report since the December 2014 update.Need for Relief/Relaxation and Basis for the Relief/Relaxation NPPD expects to comply with the Order implementation date and no relief/relaxation is required at this time.Open Items from Interim Staff Evaluation In Reference 6, the Nuclear Regulatory Commission (NRC) issued an interim staff evaluation (ISE) for CNS. The following table provides a status of the open items documented in ISE.Open Item Action Status 1 Make available for NRC staff audit analyses demonstrating In progress that HCVS has the capacity to vent the steam/energy equivalent of one percent of licensed/rated thermal power (unless a lower value is justified), and that the suppression NLS2015079 Attachment Page 3 of 4 pool and the HCVS together are able to absorb and reject decay heat, such that following a reactor shutdown from full power containment pressure is restored and then maintained below the primary containment design pressure and the primary containment pressure limit.2 Make available for NRC staff audit the seismic and tornado In progress missile final design criteria for the HCVS stack.3 Make available for NRC staff audit descriptions of all In progress instrumentation and controls (existing and planned)necessary to implement this order including qualification methods.4 Make available for NRC staff audit a determination of the In progress number of required valve cycles during the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.5 Make available for NRC audit the control document for In progress HCVS out of service time criteria 6 Make available for NRC staff to audit, an evaluation In progress verifying the existing containment isolation valves, relied upon for the HCVS, will open under the maximum expected differential pressure during severe accident wetwell venting.8 Make available for NRC staff audit documentation that In progress demonstrates adequate communication between the remote HCVS operation locations and HCVS decision makers during ELAP and severe accident conditions.
8 Make available for NRC staff audit an evaluation of In progress temperature and radiological conditions to ensure that operating personnel can safely access and operate controls and support equipment.
9 Make available for NRC staff audit the final sizing In progress evaluation for HCVS batteries/battery charger and incorporate into FLEX DG loading calculation.
10 Make available for NRC staff audit documentation of the In progress HCVS nitrogen pneumatic system design including sizing and location.11 Make available for NRC staff audit the descriptions of local In progress conditions (temperature, radiation and humidity) anticipated during ELAP and severe accident for the components (valves, instrumentation, sensors, transmitters, indicators, electronics, control devices, and etc.) required for HCVS venting including confirmation that the components are capable of performing their functions during ELAP and severe accident conditions.
