Yes. This is something we do frequently. We match the fit, form and function of the original equipment.

Yes. Oftentimes, coils and heat exchangers connected to open service water systems are subject to accelerated corrosion phenomena, the effects of which can be reduced or mitigated by using material alloys that offer more resistance to those conditions. However, a change in alloy (from copper to stainless, for example) may fall short in reaching original thermal capacity design requirements. 

Coils equipped with removable water box heads or cover plates at one end or both ends permit access to the tube internals for regular inspection and maintenance.  In some cases, SRC has upgraded legacy, pipe-header coils to new coils with water box heads having the same fit, form, and function as the original equipment.  This accessibility feature impacts component weight and must be considered when modifying the original design.

Yes. We manufacture both safety and non-safety related components to meet specific plant requirements.

Yes. If thermal performance testing is required to validate coil performance under normal operating conditions, SRC can conduct testing using a prototype model in our test laboratory. There we can test a prototype that models the exact coil heat transfer configuration and geometry and adjust the test conditions to simulate actual design conditions to validate thermal capacity.

Yes. Super Radiator has tested prototype coils under simulated accident conditions that correspond to typical containment accident conditions predicted for pressurized water reactors (PWRs). 

Yes.

Often the replication process involves some combination of reviewing drawings and manuals for the original equipment, gathering pertinent details from installed equipment during walk-downs on site, inspecting spare components in warehouse stores, and dismantling an existing component for reverse engineering in a hot shop location or at our own facility if it can be free released.  The degree of difficulty is directly related to what documentation is available, which varies greatly from plant to plant.

No. A component may be designed, fabricated, and tested in accordance with the requirements of ASME Section III and not stamped. Whether an N-stamp is required depends on the plant licensing basis or site-specific requirements. When no N-stamp is applied, no independent third-party inspection services (AIA / ANI) are included, and no N-1 data report is provided.

Yes. This is a common and normal request for replacement components at plants tied to a particular Code edition/addenda date in their licensing basis.
