Hello, everybody here,
When do we need a nozzle repad on a vessel? How to calculate the repad size? Any comments are appreciated.
Thanks in advance.

There are three kinds of people in this world; those who can count and those who can't.

As an alternate, you could increase the thickness of the shell or nozzle neck in lieu of a separate reinforcing pad. Ways to do this would include an "insert plate" in the shell. Or use a forging for the nozzle, one that has a "heavy barrel" where it attaches to the shell.
If you are left using reinforcing pads: don't make it too big (it'll be uneconomical and won't be as flexible as the shell), don't make it too small (it'll be hard to handle and weld, and hard to get test fitting in), don't use it too hot (in creep range temperatures, you'll create a hard spot on the shell), don't make it too wide (it'll flex up under nozzle loads and won't be as strong to resist those loads), etc, etc,
