Method Of Closing A Pressure Vessel
US Patent:
6763570, Jul 20, 2004
Filed:
Nov 27, 2002
Appl. No.:
10/306809
Inventors:
Stephan L. Abbott - Monroeville PA
Louis J. Tylman - Acme PA
Louis J. Tylman - Acme PA
Assignee:
Westinghouse Electric Company LLC - Pittsburgh PA
International Classification:
B23P 1700
US Classification:
2952501, 29723, 2989003, 81 5738
Abstract:
A pressure vessel having a removable closure head in a high radiation environment is closed by placing the closure head having a flange over and spaced from the flange of a pressure vessel body containing fissile material. The closure studs are installed in closure stud holes of the pressure vessel body flange. Transition nut members of hydraulic nut assemblies are threaded onto the closure studs. Hydraulic hoses are connected between the hydraulic nut assemblies and a pressure source. The pressure source simultaneously pressurizes the hydraulic nut assemblies to simultaneously apply a uniform force to the closure studs sufficient to seat the spaced apart closure head flange on the pressure vessel body flange and to elongate the closure studs. The hydraulic nut assemblies are locked in place over the closure head flange while the force is applied to the closure studs and the closure studs are elongated. The hydraulic pressure on the hydraulic nut assemblies is released while the hydraulic nut assemblies are locked in place over the closure head flange and the closure studs are elongated.
Control Rod Drive Shaft Unlatching Tool
US Patent:
2011029, Dec 8, 2011
Filed:
Jun 2, 2011
Appl. No.:
13/151305
Inventors:
Louis J. Tylman - Acme PA, US
Assignee:
Westinghouse Electric Company LLC - Cranberry Township PA
International Classification:
G21C 19/00
US Classification:
376260
Abstract:
A CRDS unlatching tool includes a support assembly and a latching assembly, wherein the support assembly is received within the latching assembly in a manner wherein the latching assembly is moveable relative to the support assembly. The support assembly has a plurality of latch fingers and at least one pin, each of the latch fingers being movable between a latched position wherein the latch finger is structured to engage and hold the CRDS an unlatched position wherein the latch finger is structured to not engage the CRDS. The latching assembly includes a first sleeve member and a second sleeve member, the second sleeve member having at least one slot, wherein the at least one pin is moveably received within the at least one slot. The latching assembly is movable from a latched state to an unlatched state wherein the latch fingers are actuated by the first sleeve member.
