Care shall be taken to prevent molten salt from creeping past the pump shaft or other flange penetrations.

    The flange seal between the pump and the sump can be obtained using a flange gasket according to ASME B16.21 (not in scope). The gasket manufacturer and model is tentatively identified as Flexitallic style “CGI” spiral wound gasket with an Inconel and

    Thermiculite winding material and type 316L inner and outer locating and reinforcement rings.

    Details of pump / sump sealing are left to the supplier.
