The MHI boilers have a main steam pressure of 27.5MPa, the main steam temperature of 605°C and a reheat steam temperature of 603°C.
That Chinese boiler commissioned in 2006
Yuhuan 1,000MW Ultra-Supercritical Pressure Boilers
The Huaneng Yuhuan power plant located on the coast of East China’s Zhejiang Province has China’s first 1,000MW ultra-supercritical pressure boilers.www.power-technology.com

The Kitty Hawk used a boiler with 8,300 kPa, while Chinese Ultra-Supercritical Pressure Boilers is 27.5MPa, the main steam temperature of 605°C.
I bet China is capable to build a much more efficient/compact boiler as well as steam turbines than Kitty Hawk.

I think space, weight and efficiency are some constrains. Please see my another post for more details.
The better way is increasing the pressure, and temperature of boiler, as well as improving the steam turbines
Ultra-supercritical pressure boilers
Yet the A1B twin reactors are 13-14 times more efficient for generating the electric power than the boilers of the Kitty Hawk.
And are you sure that the new boilers could be 13-14 times more powerful than the boilers of the Kitty Hawk? It is only 3 times at best.
That's why they have ditched the original Type 002 with steam catapults.
