ABSTRACT:
A reflective type insulation is utilized to elevate the temperature in the loop seal of a pressurizer. Damage to safety valve components and downstream piping caused by water in the piping is substantially reduced by exposing the loop seal piping to a portion of the outer surface of the pressurizer. Safety valve allowable sustained operating temperature requirements are considered in the insulation system design.
