Section 5 - Design and Operation Requirements
5-A Design and Operating Conditions
The heat exchanger is to be used for service in a
nuclear reactor experimental facility. Demineralized
water will be circulated through a system in which the
heat exchanger is used to adjust and control the
temperature of the water exiting from the experimental
section of the facility. The water is subject to
radioactive contamination and no leakage to ambient
can be tolerated. It is imperative that a high degree
of quality be incorporated in design materials and
workmanship.
The heat exchanger shall be designed to fulfill the
following service requirements and conditions:
1. Design Conditions
a. System Water Pressure 2500 psig
b. System Water Temp 650 F
c. System Water Flow 90 gpm
d. System Water DeltaP
Through the Heat Exchanger 10 psi (max)03 319
