Double ZipNut® Nozzle Dam Bolt
Unlike existing bolts, the ZipBolt® can be pushed on and tightened during the
start of the outage and quickly removed at the conclusion. This activity is always
undertaken in a high radiation area which calls for complete ALARA analysis.
The ZipNut® Nozzle Dam Bolt substantially decreases time and thus radiation
exposure to workers.
ZipBolts® have been used with great success at Carolina Power, Light's
Shearon Harris Nuclear Power Station and, the Tennessee Valley Authority.
