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 Clinton Power Station, Unit 1 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. The enclosed report provides an update of milestone accomplishments since the last status report, including any changes to the compliance method, schedule, or need for relief and the basis, if any.

Clinton Power Station, Unit 1 First Six-Month Status Report for the Implementation of Order EA-12-0S1, Order Modifying Licenses with Regard to Reliable Spent Fuel Pool Instrumentation 1 Introduction Clinton Power Station, Unit 1, developed an Overall Integrated Plan (Reference 1 in Section 8),
documenting the requirements to install reliable Spent Fuel Pool Level Instrumentation (SFPLI),
in response to Reference 2. This enclosure provides 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 The following milestones have been completed since the development of the Overall Integrated Plan (Reference 1), and are current as of August 19, 2013.
- Submitted responses to USNRC RAls (Ref. 3 and 4) on July 3,2013 3 Milestone Schedule Status The following provides an update to the milestone schedule to support the Overall Integrated Plan. This section provides the activity status of each item, and the expected completion date noting any change. The dates are planning dates subject to change as design and implementation details are developed.
The revised milestone target completion dates do not impact the order implementation date.

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 (TOR) 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 sensor cable probe and sensor electronics.
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 Page 3 of9
