Air and water in-leakage have been major problems in Power Generating Plants.  A study at one large Midwestern facility concluded that process water contamination caused 1,360 unplanned outage hours, costing the Utility over 10.9 million dollars in lost revenue.  The study also determined that more than 34% of those hours were caused by failure of hammer-in,or non metallic and rubber plugs.

Results of Condenser Plug Change-Out at Bruce Power will also be documented.

Another major issue for nuclear generating stations is loss of off-site power (LOOP). Loopcan cause the loss of the circulating water pumps that cool the reactor.  The resulting heat and pressure build up can cause ejections of rubber style plugs in the condenser. The POP-A-PLUG design as a pressure rating of 1000 psi, making them the ideal product to help reduce problems associated withLOOP.

EST re-visit the development and capabilities of the Perma Condenser Plug , review the details of the service water overhaul that resulted in over a million dollars of increased operating profit for the Utility, review LOOP Protection and reveal recent developments in plugging tubes in coated tubesheets
