Minimum Pressurization-Temperature Curves:

Plant operations are effected through the minimum pressurization-temperature curves. Personnel require to known the information which is related along with the curves to better operate the plant.

STATE the two bases used for establishing a minimum pressurization -temperature curve.

EXPLAIN   a   classical   minimum   pressure-temperature   curve involving:

a. Location of safe operating region

b. The way the curve will shift because of irradiation

LIST  the  normalactions taken , in  order,  if  the  minimum pressurization -temperature  curve  is  exceeded  in during  critical operations.

STATE the precaution for hydrostatic testing.
