Is welding to the reactor needed in order to retrofit a FLEX-R®?

No, the FLEX-R® was developed to easily retrofit to existing reactors. The technology can be retrofitted, using proper supports, with attachment to non-pressure retaining elements of the reactor internals.

Does the FLEX-R® (model TC96-R) include a secondary seal?

Yes, FLEX-R® assemblies can have a primary seal weld and a secondary seal weld from the thermocouple to the flange assembly at the face of the flange, not on a single disk, and again after the secondary containment chamber.
