this is 'just one' example ---------- take a ticket and visit a large scale nuke plant - have a look at the cooling systems

Cooling water pipes in nuclear power plants are welded by specialist welders with extensive training and qualifications. This is a critical task that requires a high degree of precision and expertise due to the extreme conditions and safety requirements in nuclear facilities.
The welding of cooling water pipes is essential for ensuring the integrity and proper functioning of the emergency cooling systems that prevent reactor meltdowns. Even minor defects in these welds could have catastrophic consequences. [1]
Specialist nuclear welders undergo rigorous training programs to master various welding processes like GTAW (gas tungsten arc welding) and orbital welding techniques. They must demonstrate proficiency in working with different metals, welding positions, and complex geometries involved in nuclear piping systems. [5]
The welding process for nuclear cooling pipes is meticulous and time-consuming. Each weld can take several days to complete, with welders often working in challenging positions and under protective gear due to radiation exposure limits. Strict quality control measures, including radiographic inspections, are employed to ensure the welds meet stringent nuclear codes and standards. [1][4]
The shortage of skilled nuclear welders has been a significant challenge for the industry, leading to delays in maintenance and repair work at nuclear plants. Countries like France have had to rely on international welders to address this shortage and ensure the safe operation of their nuclear facilities. [5] Initiatives are underway to train more specialized welders to meet the growing demand from the nuclear sector.

There's a hell of a lot more to building a power station than welding a few pipes.
Presumably they'll be 316 stainless pipes and all the welds will be rigorously radiographed.
Big deal.
