Annual check on alleged 004 nuclear land-based demonstration reactor. Still far from finished in 2022.

Where is this supposed to be? They capped the nuclear reactor main building so I would say this project is like two years from completion.

Also, for what it's worth, here is a picture of the current status of Linglong One (ACP100) 125 MWe reactor in Hainan.

Some rumor circling around since the end of last year but only some screenshots without link to official sources. Take it with a grain of salt but very likely to be authentic though.

They are mainly about a commend letter for an employee from other company to develop Project AH for 703rd Research Institute CSIC, the turbine designing branch of CSIC.

The said employee was the project manager from a subsystem company to develop Project AH for 703 and the letter also said the company has experience in Project TS, A02 and A03.

Project TS probably stands for "testing" project in CV16.
A02 and A03, as everyone has already known, is the turbine development codename for CV17 and CV18.

Meanwhile, it should have been A04 consequently if the next CV was still a conventional one. However the codename has been changed to "Project AH" where H is very likely to stand for "Nuclear."

The full name for the subsystem is
2台主汽轮齿轮机组及全尺寸集成多级汽水分离装置试验调试项目
Rough translation: Test project for 2 main turbine gear units and full-size integrated multi-stage steam and water separation unit.
Honestly I have no idea what it means and the commend letter was sent on 08/31/2022.

General
The 701 Institute is allegedly building a new facility near Wuhan that will be used to verify the steam system of a certain marine nuclear reactor. Land based boilers will be installed at the facility to provide steam at pressures necessary to simulate and verify the design. I can't vouch for the veracity of the rumor, but the

has been fairly reliable in the past.

Apparently, the construction of this facility is in full swing. The article from 701 Institute mentions frenzied activities around the clock, partly due to the extensive use of X-ray weld inspection, which can't be carried out during daytime for fear of harming other workers.

That was necessary in the 1960s, but it is not necessary in the 2020s.
If you were an engineer and had to build a 280,000 hp (horsepower) nuclear powered aircraft carrier would you choose:
a) 4 reactors at 70,000 hp each
b) 2 reactors at 140,000 hp each
and why?

4 reactors for failsafety
But that also eats into lots of spaces onboard the ship, which would have been more useful if those spaces are used for more aviation fuel & weaponry storage and/or crew quarters. The work required for the maintenance of the reactors, coupled with the refueling and overhaul of the reactors during the ship's mid-life refit, would also multiply significantly.
