See Page 3 On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued an Order (Reference 1) to all power reactor licensees and holders of construction permits in active or deferred status. The Order was effective immediately and required the Omaha Public Power District (OPPD) to develop, implement, and maintain guidance and strategies to maintain or restore core cooling, containment, and spent fuel pool cooling capabilities in the event of a beyond-design-basis external event (BDBEE). Specific requirements are described in Attachment 2 of the Order.
Pursuant to Section IV, Condition C.2 of the Order, licensees are to provide a status report at six-month intervals following submittal of the Overall Integrated Plan (OIP),
which OPPD submitted on February 28, 2013 (Reference 4). In August 2014, OPPD provided the third six-month status report (Reference 7) describing progress made in implementing the requirements of the Order; this letter provides the fourth six-month status report.
The OIP (Reference 4) and subsequent six-month status reports were prepared utilizing NEI guidance (Reference 2) as endorsed with exceptions and clarifications by the NRC in Reference 3.
There are no regulatory commitments contained in this submittal.
If you should have any questions regarding this submittal, please contact Mr. Bill R.

LIC-15-0032 Enclosure Page 1 Fort Calhoun Station, Unit No.1 Fourth Six-Month Status Report for the Implementation of Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events 1
Introduction The Omaha Public Power District (OPPD) developed an Overall Integrated Plan (Reference 1) 1 documenting the diverse and flexible strategies (FLEX), in response to Reference 2.
This enclosure and its attachments provide an update of milestone accomplishments since submittal of the Overall Integrated Plan, including any changes to the compliance method, schedule, or need for relief/relaxation and the basis, if any.
2 Milestone Accomplishments Control Room Heatup Calculation and Water Quality Evaluations are complete.
FLEX Support Guideline Basis Documents and Executive volume have been issued.
Draft Lower Mode FLEX Support Guidelines have been issued.
Beyond-Design-Basis (BDB) Flooding Strategy has been established for all potential flooding elevations.
3 Milestone Schedule Status contains an update to the Milestone Schedule (Reference 1, Enclosure, ) provided with the Overall Integrated Plan.
The status of each milestone is shown, as are revised completion dates. The dates are planning dates subject to change as design and implementation details are developed. Attachment 1 is formatted to align with the table provided in the Nuclear Energy Institute's (NEI) Six-Month Status Report Template and supersedes the Milestone Schedule provided by Reference 1.
The evaluation of FLEX modifications is largely complete. However, the completion date was revised to April 2015 to accommodate incorporation of equipment pre-staging/storage to address BDB flooding.
This also impacted the FLEX strategy evaluation and procedures, development of a training plan and staffing evaluation causing their completion dates to be revised as well. The creation of FLEX Equipment maintenance procedures was adjusted to align with the expected arrival of all FLEX equipment on-site. The revised completion dates do not impact the implementation date of the Order.
4 Changes to Compliance Method There are no changes to the compliance method as documented in the Fort Calhoun Station Overall Integrated Plan (Reference 1). The results of the control room heatup calculation (see Overall Integrated Plan Open Item #2 in Section 6, below) show that control room cooling will not be required for a significantly longer period of time than was assumed in the Overall Integrated Plan timeline. OPPD is evaluating the method that will be used to establish cooling to the control room and will provide an update to the strategy in a future 6-month update.
1 Documents referenced in this enclosure are listed in Section 8.
LIC-15-0032 Enclosure Page2 As discussed in previous 6-month updates, OPPD has developed an interim strategy to address BDB flooding. This strategy is similar to that described in Reference 1, Enclosure, Appendix B, Action 24, but involves a slightly different portable equipment configuration to accommodate issues not yet addressed by FLEX modifications.
Results of the Near Term Task Force Recommendation 2.1 flooding hazard re-analysis (Reference 4) indicated that certain Missouri River dam failures might result in floods exceeding the elevation currently addressed by the interim BDB flooding strategy. OPPD has revised the interim BDB flooding strategy to address the potential higher flooding levels. The interim equipment and strategies will be incorporated into the FLEX Overall Integrated Plan. Certain modifications are being considered to improve protection and deployment of the flood mitigation equipment. Once those modifications are finalized, OPPD will describe the integration of the interim flood strategy into the Overall Integrated Plan in a future six-month update.
5 Need for Relief/Relaxation and Basis for the Relief/Relaxation OPPD expects to comply with the Order's implementation date and no relief/relaxation is required at this time.
6 Open Items from Overall Integrated Plan and Draft Safety Evaluation The following tables provide a summary of the open items documented in the Overall Integrated Plan (Reference 1) or the Draft Safety Evaluation (SE) and the status of each item.
