U.S. Nuclear Regulatory Commission Report of Full Compliance with Order EA-12-051 June 9, 2015 Page 5 INSTRUMENT DESIGN FEATURES -COMPLETE The design of the instruments installed at Braidwood Station complies with the requirements specified in the Order and described in NEI 12-02 "Industry Guidance for Compliance with NRC Order EA-12-051". The instruments have been installed in accordance with the station design control process. The instruments have been arranged to provide reasonable protection against missiles. The instruments have been mounted to retain design configuration during and following the maximum expected ground motion. The instruments will be reliable during expected environmental and radiological conditions when the SFP is at saturation for extended periods. The instruments are independent of each other and have separate and diverse power supplies. The instruments will maintain their design accuracy following a power interruption and are designed to allow for routine testing and calibration. The instrument display is readily accessible during postulated events and allows for SFP level information to be promptly available to decision makers. PROGRAM FEATURES -COMPLETE Training for Braidwood Station, Units 1 and 2 has been completed in accordance with an accepted training process as recommended in NEI 12-02, Section 4.1. Operating and maintenance procedures for Braidwood Station have been developed and integrated with existing procedures. Procedures have been verified and are available for use in accordance with the site procedure control program. Site processes have been established to ensure the instruments are maintained at their design accuracy. This letter contains no new regulatory commitments.

. These levels have been integrated into the site processes for monitoring level during events and responding to loss of SFP inventory.
U.S. Nuclear Regulatory Commission Report of Full Compliance with Order EA-12-051 June 9, 2015 Page 5 INSTRUMENT DESIGN FEATURES
-COMPLETE The design of the instruments installed at Braidwood Station complies with the requirements specified in the Order and described in NEI 12-02 "Industry Guidance for Compliance with NRC Order EA-12-051".
The instruments have been installed in accordance with the station design control process.
The instruments have been arranged to provide reasonable protection against missiles.
The instruments have been mounted to retain design configuration during and following the maximum expected ground motion. The instruments will be reliable during expected environmental and radiological conditions when the SFP is at saturation for extended periods.
The instruments are independent of each other and have separate and diverse power supplies.
The instruments will maintain their design accuracy following a power interruption and are designed to allow for routine testing and calibration.
The instrument display is readily accessible during postulated events and allows for SFP level information to be promptly available to decision makers. PROGRAM FEATURES
-COMPLETE Training for Braidwood
- Station, Units 1 and 2 has been completed in accordance with an accepted training process as recommended in NEI 12-02, Section 4.1. Operating and maintenance procedures for Braidwood Station have been developed and integrated with existing procedures.
Procedures have been verified and are available for use in accordance with the site procedure control program.
Site processes have been established to ensure the instruments are maintained at their design accuracy.
