Patent number: 11276502Abstract: Fuel bundles for a nuclear reactor are disclosed, and in some embodiments include a first fuel element including thorium dioxide; a second fuel element including uranium having a first fissile content; and a third fuel element including uranium having a second fissile content different from the first fissile content. Nuclear reactors using such fuel bundles are also disclosed, including pressurized heavy water nuclear reactors. The uranium having the different fissile contents can include combinations of natural uranium, depleted uranium, recycled uranium, slightly enriched uranium, and low enriched uranium.Type: GrantFiled: October 11, 2017Date of Patent: March 15, 2022Assignee: ATOMIC ENERGY OF CANADA LIMITEDInventors: Mustapha Boubcher, Sermet Kuran, Cathy Cottrell, Robert R.

Patent number: 10847270Abstract: A nuclear reactor can include a pressure vessel for containing a pressurized moderator at a first pressure. The nuclear reactor can also include a plurality of fuel channels for a coolant fluid at a second pressure. The plurality of fuel channels are fluidly connected at inlet ends thereof to a coolant supply conduit and are adapted to receive nuclear fuel bundles and to be mounted within the pressure vessel and surrounded by the moderator. The outlet ends of the fuel channels are fluidly connected to a coolant outlet conduit to enable the coolant fluid to circulate from the coolant supply conduit through the fuel channels to the coolant outlet conduit. The plurality of fuel channels maintain separation between the coolant fluid circulating within the fuel channels and the moderator.Type: GrantFiled: June 22, 2017Date of Patent: November 24, 2020Assignee: Atomic Energy of Canada Limited / Energie Atomique du Canada LimiteeInventors: Robert Bodner, Jonathan Tyo, Dan Popov, Sermet Kuran
