Ambient temp of nuclear SG during wet layup 1

[miascab]

What exactly is the "ambient temperature" of nuclear steam generators during wet layup?
Some literature state ambient temp as 93 degrees Celsius.
I found another one that said wet layup ambient temp was at 150 degrees Celsius.
Is there an industry standard for ambient temp of nuclear steam generators in wet layup conditions?

Thank you in advance.

I normally use "below the boiling point of water" So, unless the steam generators are at nearly 5 bars pressure, 150 degrees is a bit much.
