A modern nuclear cruiser as an energy-weapon platform

Would a modern nuclear-powered cruiser represent a major change from earlier CGNs?

Its major advantage could be a hybrid electric plant that pairs nuclear base load with gas-turbine surge power for energy-intensive weapons.

One proposed advantage of a modern nuclear-powered cruiser is the electricity available for lasers and railguns. A combined nuclear and gas plant could use integrated electric power to serve those loads. The reactor would provide steady base load, with gas turbines brought on to supply additional demand during sustained firing. The proposal aims to avoid repeatedly increasing and decreasing reactor output.
