Abstract

The present invention relates to a method for manufacturing a tracer-encapsulated solid pellet for magnetic-confinement fusion, the method comprising a liquid droplet formation step of discharging an organic liquid containing an organic solvent into a stabilizing liquid to thereby form liquid droplets 12, and an organic solvent removal step of removing the organic solvent from the liquid droplets 12A. The organic liquid to be used is a liquid having a first organic polymer containing tracer atoms and a second organic polymer being an organic polymer different from the first organic polymer dissolved in the organic solvent, wherein the first organic polymer and the second organic polymer can be mutually phase-separated.

First claim

The invention claimed is:

1. A method for manufacturing a tracer-encapsulated solid pellet for magnetic-confinement fusion, the method comprising:
a liquid droplet formation step of discharging an organic liquid comprising an organic solvent into a stabilizing liquid to thereby form a liquid droplet; and

wherein the organic liquid is a liquid having a first organic polymer comprising a tracer atom and a second organic polymer being an organic polymer different from the first organic polymer dissolved in the organic solvent;
the first organic polymer and the second organic polymer can be mutually phase-separated;
the organic liquid has a first organic liquid and a second organic liquid prepared separately from each other;
the first organic liquid comprises the first organic polymer;
the second organic liquid comprises the second organic polymer; and
in the liquid droplet formation step, by using a combined nozzle equipped with a first nozzle and a second nozzle having a discharge port surrounding a discharge port of the first nozzle, the first organic liquid and the second organic liquid are discharged simultaneously from the first nozzle and the second nozzle, respectively.

2. A method for manufacturing a tracer-encapsulated solid pellet for magnetic-confinement fusion, the method comprising:
a liquid droplet formation step of discharging an organic liquid comprising an organic solvent into a stabilizing liquid to thereby form a liquid droplet; and
an organic solvent removal step of removing the organic solvent from the liquid droplet,
wherein the organic liquid is a liquid having a first organic polymer comprising a tracer atom and a second organic polymer being an organic polymer different from the first organic polymer dissolved in the organic solvent;
the first organic polymer and the second organic polymer can be mutually phase-separated; and
the first organic polymer comprising a tracer atom is a polymer selected from polymers belonging to the polymer group consisting of organic polymers having metal atoms or semimetal atoms bonded thereto, organic polymers having halogen atoms bonded thereto and organic polymers having a tracer substance dispersed therein.

3. The method for manufacturing a tracer-encapsulated solid pellet for magnetic-confinement fusion according to claim 1 , wherein at least one of the first organic polymer and the second organic polymer is a hydrocarbon-based polymer.

4. The method for manufacturing a tracer-encapsulated solid pellet for magnetic-confinement fusion according to claim 2 , wherein at least one of the first organic polymer and the second organic polymer is a hydrocarbon-based polymer.
