Field Services Case Study

Field Services Nuclear

Faced with an emergent need to replace a reactor coolant system primary check valve at the Sequoyah Nuclear Plant, the Tennessee Valley Authority turns to Tri Tool to deliver quality on an expedited time frame.

During a routine outage at the Sequoyah Nuclear Plant a nuclear power plant owned by the Tennessee Valley Authority (TVA) that generates enough power for 1.3 million homes each day plant personnel unexpectedly found that a Reactor Coolant System (RCS) primary check valve needed to be replaced. However, the valve was located in a very congested area that required special considerations due to various radiological conditions.

Find out how Tri Tool mobilized a crew of pipefitters, machinists, and welders within 24 hours to execute a "like-for-like" replacement of the valve with zero safety or performance issues.
