Following are my comments:

Maximum Power

This should be MW - not kW (a typo!)

a) The facility shall be designed for a maximum power of 350MW for 0.3s for the Initial Ohmic Phase of operation.
b) The capability to accommodate (as a future upgrade) heat loads associated with up to 12MW of power for 1.2s (including 6MW of neutral beam injection) shall be provided.

Pulse Repetition Rate

The facility shall be designed for pulses to be initiated at intervals not exceeding 15 minutes when constrained by coil cool-down and 5 minutes otherwise.
Why the 15 minutes constraint? The 5 minute repetition time seems to be an adequate constraint.

1.1.1.1 Experimental Power

All experimental power for NCSX will be provided through the C-site experimental power systems except for the TF, PF, and modular coil power supplies that are connected to the D-site experimental power systems.
I think the emphasis has to be D-Site power system. Hence can we reword the same as below?
" The bulk of the experimental power is derived form D-Site and is used for all the coil systems except for Trim Coils. The rest of the power is provided from the C-Site systems."
