Mechanical Spectral Shift Reactor

US Patent:
4692296, Sep 8, 1987
Filed:
Dec 24, 1986
Appl. No.:
6/946111
Inventors:
Donald G. Sherwood - Monroeville PA
John F. Wilson - Murrysville PA
Robert B. Salton - Plum PA
Howard F. Fensterer - Plum PA
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
G21C 726
US Classification:
376209
Abstract:
The mechanical spectral shift reactor comprises apparatus for inserting and withdrawing water displacer elements from the reactor core for selectively changing the water-moderator volume in the core thereby changing the reactivity of the core. The apparatus may include drive mechanisms for moving the displacer elements relative to the core and guide mechanisms for guiding the displacer rods through the reactor vessel. An array of tubes may be disposed between the guide mechanisms and the fuel assemblies for guidance and minimization of flow induced vibrations of the displacer elements.
