You asked of our description of long term boration strategy. As stated as the answer to question 3.2.1.1.D in Byrons Fourth Six-Month Status Report in Response to March 12, 2012 Commission Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events (Order Number EA-12-049), dated February 27,2015, Calculation BYR 14-129 / BRW-14-0212-M, RWST Usage During FLEX Scenarios has been completed to determine the need and timing of additional Phase 3 boration equipment. This calculation states that with all the scenarios run the RWSTs will provide borated water for a minimum of 33.6 hours (enough time to get equipment from the SAFER location). Additionally, Byron has BFSG-50, FLEX Support Equipment Operation Unit - 0. Attachment G of 0BFSG-50 provides steps to refill the RWST from 1) Cross-tie from the other unit, 2) Portable boration / makeup skid, and 3) Boric Acid Storage Tank.
