On March 12, 2012, the Nuclear Regulatory Commission ("NRC" or "Commission") issued an order (Reference 1) to Exelon Generation Company, LLC (EGC). Reference 1 was immediately effective and directs EGC to install reliable spent fuel pool level instrumentation. Specific requirements are outlined in Attachment 2 of Reference 1.
Reference 1 required submission of an initial status report 60 days following issuance of the final interim staff guidance (Reference 2) and an overall integrated plan pursuant to Section IV, Condition C. Reference 2 endorses industry guidance document NEI 12-02, Revision 1
u.s. Nuclear Regulatory Commission Integrated Plan Report to EA-12-051 August 28, 2013 Page 2 (Reference 3) with clarifications and exceptions identified in Reference 2. Reference 4 provided the EGC initial status report regarding reliable spent fuel pool instrumentation. Reference 5 provided the Braidwood Station, Units 1 and 2 overall integrated plan.
Reference 1 requires submission of a status report at six-month intervals following submittal of the overall integrated plan. Reference 3 provides direction regarding the content of the status reports. The purpose of this letter is to provide the first six-month status report pursuant to Section IV, Condition C.2, of Reference 1, that delineates progress made in implementing the requirements of Reference 1.

Braidwood Station, Units 1 and 2 First Six-Month Status Report for the Implementation of SFPLI August28,2013 Ref.4) The detailed design will include a calculation to determine adequate water level to maintain normal fuel pool cooling system operation. This information will be available following acceptance of the 100% design, scheduled for April, 2014. The result will be provided in the August 2014, 6-month Integrated Plan update report to the NRC.

sensing technology that will be The instrument is a guided wave radar determined during the detailed system. It provides the capability to engineering phase of the project. reliably monitor the spent fuel pool water level under normal and anticipated adverse environmental conditions.
The sensor input to the system is a guided wave radar probe. Using the principle of time domain reflectometry (TDR) to detect the SFP water level, microwave signals are pulsed down the cable probe and reflected back from the water surface. This is used to determine the level of the water in the pool.
Each water level measurement channel includes a flexible stainless-steel sensor cable probe suspended in the spent fuel pool from a seismic Category 1 bracket attached to the operating deck or to a raised curb at the side of the pool. The cable probe extends to just above the top of the spent fuel racks. The sensor electronics are mounted in seismic and missile protected areas outside of the building housing the SFP to minimize exposure to elevated radiation and environmental conditions which could result from a postulated loss of water inventory in the pool. There is an interconnecting cable between the Page 3 of9

The sensor electronics provide an instrument standard analog signal to a remote enclosure that will be installed in an accessible location. This enclosure contains the Uninterruptable Power Supply (UPS), backup battery, and water level display. The enclosure also includes the capability to connect an emergency or temporary external power source as part of the FLEX mitigating strategies.
