Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
165 words
A reactor pressure vessel penetration apparatus for feedwater delivery comprising an inlet feedwater line external to the pressure vessel, a flange formed on the end of the feedwater line that is adjacent to the pressure vessel, a nipple protruding from the pressure vessel surface, means for joining the feedwater line and the nipple, said nipple having a flange formed on the end thereof oppositely disposed to and in axial alignment with the feedwater line flange, a plate having an orifice formed in the center thereof interposed between the flanges, a thermal shield secured to the orifice plate and having an axis that is in general alignment with the orifice, said thermal shield protruding through the pressure vessel, a tube formed on the nipple flange and in axial alignment therewith extending through the pressure vessel in axial alignment about the thermal shield, and a sleeve of several laminations of reflective thermal insulation interposed in an annulus that is formed between the pressure vessel and the tube.
