FDRP 29-004 - EC 626215 provides a new deluge system for the Unit 1 Unit Auxiliary Transformers (UATs) 141-1 and 141-2. The new deluge systems have a different physical configuration as compared to the original system; however, this does not change the function of the fire suppression system. The UATs are replaces as parts of a separate change package (EC 525040 and FDRP 29-003). The fire protection report is being revised to update table 3-1 and appendix 5.4 figures (BYR).
, FDRP 29-005 - EC 626661 permanent removes the charcoal from the Unit 1 containment charcoal filter units and permanently isolates the fire protection deluge system for that system.
Per Byron SER Amendment 76 allows the Containment Mini-flow and Post LOCA Purge System to be used to reduce containment airborne radioactivity prior to personnel access. This allows the charcoal adsorbers (1VP05FA/B) to be abandoned and removed along with Its associated trays, hardware-and test canisters from the CCFUS (1VP01SA/B) while maintaining the ability to reduce containment airborne radioactivity prior to personnel access. Further permitting the abandonment in place and isolation of the deluge system. Isolation will be achieved by removing the ability to open 1 FP244A/B from the control room and taking 1 FP2245A/B from locked open to closed. The alarm associated with 1 FP2245A/B being closed will also be eliminated. The fire protection report is being revised to update figure 2.3-10, table 2.2-3, section 2.3.1.5, section 3. 7 and table A5.4-1 (BYR).
FDRP 29-006 - EC 627474 (DRP 11-039) as described in Byron/Braidwood UFSAR subsection 6.2.5, the hydrogen recombiners and backup hydrogen vent and purge subsystems are no longer required for the Byron and Braidwood combustible gas control system. The fire protection report is being revised to reflect abandonments in table 2.2 and section 2.3 (BYR/BRW).
FDRP 29-007 - EC 6284881 adds instrument cables associated with Steam Generator (SIG) power operated relief valves (PORVs) analyzed through multiple spurious operation (MSO) scenario 22. The fire protection report is being revised to update table 2.4-4 of the Safe Shutdown Analysis (SSA) to include the instrument cables (BYR).
FDRP 29-008 - EC 397450 installs permanent robust operation banier covers on to 480-volt motor control centers in the auxiliary building. The fire protection report is being revised to update table 2.2 and section 2.3 for added combustible materials (BRW).

Incorporated into Braidwood/Byron Stations Fire Protection Report - Amendment 29*
FDRP 2M09 - EC 626345 abandons select UV detectors. Referring to Byron and Braidwood SE R's and supplements thereto, select UV detectors are not required in select fire zones. The UV detectors were Installed prior to NRC inspection and approval and are unnecessary or incorrect for the application. Since appropriate detection and/or suppression is already Installed at the required locations in addition to the UV detector, the UV detectors are abandons in place and still comply with the applicable codes and licensing basis. The fire protection report is being revised to update section 2.2, table 2.2, section 2.3, section 3, and section 5.4 (BYR).
FDRP 29-010 - EC 627885 Installs a fourth Statton Air Compressor (SAC) in the Unit 2 Turbine building. The fire protection report Is being revised to update Section 2.3.8.5, Figures 2.3-12 (sheet 4 of 4) and 2.3-23 (sheet 2 of 2) (BRW).

The fire protection report is being revised to update table 3-1 (BYR).
FDRP 29-012- NFPA code date of issue in table 3-1 lists NFPA code 72E as code year 1984.
This is incorrect as Byron was reviewed for compliance to the 1982 code. The fire protection report is being revised to update table 3-1 (BYR).
FDRP 29-013- Section 3.5(g), Lighting and communication, of the fire protection report only references the power supply for the Unit 1 plant pager system. The referenced circuit, "F3" is not the only circuit providing power, circuit aF2* also supplies power. Unit 2 is supplied from 2 circuits, aF2" and *F3". The select NRC position for section 3.5(g)(3) states "Fixed emergency communications Independent of the normal plant communication system should be installed at preselect stations." Under the implementation for noncompliance sections it states that Byron complies and references plant pager system drawings for location and power for Unit 1 only.
The additional information regarding drawings and power supplies is not required to prove compliance, the justification will be updated to include unit 2 MCC (231X2) but will remove reference to individual circuits. The fire protection report is being revised to update section 3.5 (BYR).
FDRP 29-016-Changed affected page listing to list pages affected by update and not all pages. Updated formatting and corrected spelling errors. Aligned fire zone naming conventions between table 2.2-2 and 2.2-3. Removed listing of combustible loads in table 2.2-3 due to redundancy in section 2.3. Added fire zone floor area to section 22 and removed from section 2.3. Clarified Byron or Braidwood specific items in section 2.3. The fire protection report is being revised to update section 1.~. 2.0, 2.1, 2.2, and 2.3 (BYR/BRW).
