HVAC Flue Duct Expansion Joint on Reactor Building Refueling Cavity Ventilation System

Problem

Fabric Flue Duct Joints can fail prematurely due to the movement and stresses on HVAC Ventilation systems. They are also difficult to install / align. Tearing of old joints can lead to asbestos contamination.

Reactor Building Refueling Cavity Ventilation Systems are critical to the safe operation of nuclear plants – these systems assist in radiation control and local critical equipment cooling. Specifically these systems pull air off of the refueling cavity to help control radioactive contamination.

Solution

Garlock Style 8400 Expansion Joints installed in this system provide very long life and dependability. Style 8400 is a fabric reinforced elastomeric joint that offers superior durability, sealability, and longer service life compared to other fabric expansion joints. The expansion joints are custom made to fit and offer easy installation. Specific Garlock 8400 expansion joints have been installed in this application and leak free since 1977.
