Abstract

A liquid metal cooled molten salt reactor having a liquid metal vessel connected to a gas chamber that is connected to a molten salt chamber that is connected with a hot liquid metal vessel. A fuel salt that is withdrawn from the fuel salt tank through a feeding tube into the molten salt chamber from which the fuel salt is withdrawn into a salt separator. A purging gas is inserted into the gas chamber and withdrawn. A liquid metal coolant is dispensed from the liquid metal vessel through a plurality of dispensing nozzles into the molten salt chamber. The liquid metal coolant flows through the molten salt into a hot liquid metal vessel and then through a liquid metal filter into a liquid metal pump. The liquid metal coolant flows through a thermal exchanger subsequently returning to the liquid metal vessel.

First claim

The invention claimed is:

1. A liquid metal cooled molten salt reactor comprising:
a) a core containing a first liquid metal vessel fluidly connected with a gas chamber, the gas chamber fluidly connected with a molten salt chamber, and the molten salt chamber fluidly connected with a second liquid metal vessel;
b) a fuel salt tank containing a fuel salt NaCl—KCl—PuCl 3 , the fuel salt is withdrawn from the fuel salt tank through a fuel salt feeding tube into the molten salt chamber, the fuel salt is withdrawn from the molten salt chamber through a fuel salt effluent tube into a salt separator;
c) a purging gas inlet, the purging gas inlet inserting a purging gas into the gas chamber, the purging gas is withdrawn from the gas chamber through a purging gas outlet; and
d) a liquid metal coolant dispensed from the first liquid metal vessel through a plurality of dispensing nozzles positioned within the gas chamber, such that the liquid metal coolant is dispensed first into the gas chamber, and then flows into the molten salt chamber, the liquid metal coolant flows through the fuel salt in at least the molten salt chamber and receives heat from the molten salt chamber, the liquid metal coolant then flows into the second liquid metal vessel, the liquid metal coolant flows from the second liquid metal vessel through a liquid metal filter into a liquid metal pump, the liquid metal coolant flows from the liquid metal pump through a thermal exchanger in which the heat received from the molten salt chamber is removed from the liquid metal coolant, and the liquid metal coolant then returns to the first liquid metal vessel.

2. The liquid metal cooled molten salt reactor of claim 1 wherein the liquid metal coolant is lead, tin, lead-bismuth, or a combination thereof.

3. The liquid metal cooled molten salt reactor of claim 1 wherein the liquid metal coolant is dropped from the plurality of dispensing nozzles into at least the gas chamber.

4. The liquid metal cooled molten salt reactor of claim 1 wherein the fuel salt includes dissolved nuclear fuel 233 UF 4 .

5. A liquid metal cooled molten salt reactor comprising:
a) a core containing a first liquid metal vessel fluidly connected with a gas chamber, the gas chamber fluidly connected with a molten salt chamber, and the molten salt chamber fluidly connected with a second liquid metal vessel;
b) a fuel salt tank containing a fuel salt, the fuel salt is withdrawn from the fuel salt tank through a fuel salt feeding tube into the molten salt chamber, the fuel salt is withdrawn from the molten salt chamber through a fuel salt effluent tube into a salt separator;
c) a purging gas inlet, the purging gas inlet inserting a purging gas into the gas chamber, the purging gas is withdrawn from the gas chamber through a purging gas outlet;
d) a plurality of dispensing nozzles positioned within the gas chamber; and
e) a liquid metal coolant dispensed from the first liquid metal vessel through the plurality of dispensing nozzles such that the liquid metal coolant is dispensed first into the gas chamber and then flows into the molten salt chamber, the liquid metal coolant flows through the fuel salt receiving heat from the molten salt chamber and flows into the second liquid metal vessel, the liquid metal coolant flows from the second liquid metal vessel through a liquid metal filter into a liquid metal pump, the liquid metal coolant flows from the liquid metal pump through a thermal exchanger in which the heat received from the molten salt chamber is removed from the liquid metal coolant, and the liquid metal coolant then returns to the first liquid metal vessel.
