Patents by Inventor Ajay Bhattacharyya

Ajay Bhattacharyya has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Nuclear core and a reflector assembly therefor
    Patent number: 4166003
    Abstract: A nuclear core including a reflector assembly cooling arrangement utilizing a combination of forced and natural convection cooling. Forced convection cooling is achieved by using a low pressure gradient to drive coolant through the reflector assembly. Natural convection cooling of the reflector assembly is accomplished by using heat from the reflector assembly and cooling provided by core bypass coolant flow to circulate coolant by natural means through the reflector assembly.
    Type: Grant

  • Variable flow control for a nuclear reactor control rod
    Patent number: 4118275
    Abstract: A variable flow control for a control rod assembly of a nuclear reactor that depends on turbulent friction though an annulus. The annulus is formed by a piston attached to the control rod drive shaft and a housing or sleeve fitted to the enclosure housing the control rod. As the nuclear fuel is burned up and the need exists for increased reactivity, the control rods are withdrawn, which increases the length of the annulus and decreases the rate of coolant flow through the control rod assembly.
