to the end fitting on each end of the fuel channel assembly. The feeder couplings form a
pressure-tight connection, between the end fittings and the feeder pipes, which form a part of the
Primary Heat Transport System.
The screws are to comply with the pertinent sections of the ASME Code as defined herein.
a) ASME Boiler and Pressure Vessel Code, Section II,
b) ASME Boiler and Pressure Vessel Code, Section III,
c) ASME Boiler and Pressure Vessel Code, Section V.
Areas of control will likely include, but not be limited to:
