In section 3.0 of the LAR, the licensee states:

McGuire Updated Final Safety Analysis Report [UFSAR] Figure 9-143 provides a summary flow diagram of the VG [Starting Air] system. Note that this figure will be revised to show the cross-connection line between the VG sub-trains upstream of the VG receiver tanks.

Please provide the proposed revised figure referenced in section 3.0 of the LAR so that the proposed cross connection is clearly identified.

- 2 In Section 3.0 of the LAR, the licensee states:

Empirical test data from VG system testing was used to determine the mass of air required per start during multiple starts from a single air receiver.

Section 9.5.6.1, "Design Bases," of the UFSAR states:

Analysis based on results obtained during testing finds the McGuire diesels are capable of starting 5 times consecutively from the initial conditions of one of the two starting air receivers isolated, the other receiver at the lowest pressure allowed by Technical Specifications and diesel room temperature at the highest allowed by Selected License Commitments.
