2.6.3 Class 1E dc and Uninterruptible Power Supply System Design Description The Class 1E dc and uninterruptible power supply system (IDS) provides dc and uninterruptible ac electrical power for safety-related equipment during normal and off-normal conditions.

The IDS is as shown in Figure 2.6.3-1 and the component locations of the IDS are as shown in Table 2.6.3-4.

1. The functional arrangement of the IDS is as described in the Design Description of this Section 2.6.3.
2. The seismic Category I equipment identified in Table 2.6.3-1 can withstand seismic design basis loads without loss of safety function.
3. Separation is provided between Class 1E divisions, and between Class 1E divisions and non-Class 1E cables.
4. The IDS provides the following safety-related functions:

a) The IDS provides electrical independence between the Class 1E divisions.

b) The IDS provides electrical isolation between the non-Class 1E ac power system and the non-Class 1E lighting in the MCR.

c) Each IDS 24-hour battery bank supplies a dc switchboard bus load for a period of 24 hours1 days <br />0.143 weeks <br />0.0329 months <br /> without recharging.

d) Each IDS 72-hour battery bank supplies a dc switchboard bus load for a period of 72 hours3 days <br />0.429 weeks <br />0.0986 months <br /> without recharging.

e) The IDS spare battery bank supplies a dc load equal to or greater than the most severe switchboard bus load for the required period without recharging.

f) Each IDS 24-hour inverter supplies its ac load.

g) Each IDS 72-hour inverter supplies its ac load.

h) Each IDS 24-hour battery charger provides the protection and safety monitoring system (PMS) with two loss-of-ac input voltage signals.

i) The IDS supplies an operating voltage at the terminals of the Class 1E motor-operated valves identified in subsections 2.1.2, 2.2.1, 2.2.2, 2.2.3, 2.2.4, 2.3.2, 2.3.6, and 2.7.1 that is greater than or equal to the minimum design voltage.

j) The IDS provides electrical isolation between the non-Class 1E battery monitors and the Class 1E battery banks

5. The IDS provides the following nonsafety-related functions:

a) Each IDS 24-hour battery charger supplies a dc switchboard bus load while maintaining the corresponding battery charged.

b) Each IDS 72-hour battery charger supplies a dc switchboard bus load while maintaining the corresponding battery charged.

c) Each IDS regulating transformer supplies an ac load when powered from the 480 V motor control center (MCC).
