SSF External Flood Protection 16.9.21 SURVEILLANCE REQUIREMENTS SURVEILLANCE FREQUENCY SR 16.9.21.1 NA NA BASES This SLC provides monitoring of Maintenance Rule High Safety Significant Function 8094.3, Provide barrier to external flooding of the SSF. Based on information from the Oconee Probabilistic Risk Assessment (PRA), external flood walls were installed at the south and north entrances to the SSF Building to reduce the consequences of a Jocassee dam failure.

Following installation of the flood walls, the SSF is protected from flooding to an elevation of 801'. SSF flood barriers are adequate to protect the SSF from the most probable Jocassee dam failure flood scenarios.

Access through the south wall is provided through a water tight door. A stairway over the north flood wall provides access to the north entrance. Flood protection integrity of the SSF must be maintained except for normal ingress and egress through the south side water tight door. In addition to the flood wall located at the north entrance to the SSF and to the flood wall and water tight door located at the south entrance to the SSF, the following features prevent flood water from entering the SSF:

" SSF exterior concrete wall (not located within area protected by north and south flood walls).

SSF exterior concrete wall located below 801' is credited. Though the SSF exterior concrete wall was not originally designed for external flooding due to a Jocassee dam failure, the design of the SSF exterior concrete wall is considered to be inherently capable of providing adequate flood protection.

" Bolted plate and bolted access plate located at CO 2 fill lines that penetrate the South wall of the SSF.

An access hole through the bolted plate that surrounds the CO 2 fill lines at the South wall penetration was installed to provide a path for providing temporary power to the SSF. Since the access hole is located below 801', the bolted access cover shall be installed to provide external flood protection.

  • SSF sewer system piping including check valve ST-53 and downstream SSF sewer system piping located inside the SSF.

Check valve ST-53 prevents flood water from entering the SSF via the SSF sewer system.

SSF External Flood Protection 16.9.21 Piping and electrical exterior wall penetration seals located below 801' elevation.

When flood protection integrity of the SSF is degraded, a risk assessment shall be performed immediately by RA A.1. RA A.1 is required to be performed in conjunction with either, RA A.2.1 to implement compensatory measures in accordance with Table 16.9.21-1 or RA A.2.2 to restore SSF External Flood Protection Integrity within 7 days. A 7-day Completion Time is sufficient for either of these RA.

Table 16.9.21-1 Compensatory Actions Com# Protective Measure Compensatory Actions 1 Flood protection integrity of the 1. Place sandbags at breach.

SSF building shall be maintained 2. Place sealing materials at breach.

3. Take other appropriate measures to provide flood protection to SSF.

This SLC addresses SSF external flood protection which is considered in the Oconee PRA for floods up to elevation 801'. SSF External flood protection is not a licensed requirement of the SSF. Therefore, entry into Condition A of this SLC does not require entry into any TS.

However, there is a potential that the SSF's mitigation of a Turbine Building flood could be affected if a flood protection feature located at an elevation of < 796.5' is defeated. Condition B requires immediate entry into applicable TS (TS 3.10.1 Condition A, B, C, D, and E) if a flood protection feature located at an elevation of < 796.5' is defeated.

Condition C will also initiate a PIP within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> if required actions and associated completion times are not met.

The Actions are modified by a NOTE that states that the Conditions are not applicable if SSF External Flood protection integrity is breached due to planned maintenance activities which require contingency measures prior to breaching the barrier. Contingencies as specified by Table 16.9.21-1 or the Control of Passive Design Features Site Directive will be in place when SSF External Flood protection integrity is intentionally breached. SLC actions will not be required.
