The present disclosure provides a method for manufacturing a unit cell including the steps of: preparing an electrode and a separator individually, wherein the separator includes a porous polymer substrate and a porous coating layer disposed on at least one surface of the porous polymer substrate and including a mixture of inorganic particles with a binder polymer; applying a lamination solvent to the surface of the separator to be bound with the electrode; and carrying out lamination of the electrode with the separator before the lamination solvent is dried. The method according to the present disclosure can solve the problem of shrinking of a separator occurring in the conventional lamination process.

Provided is a method of manufacturing a high strength ferritic/martensitic steel. The method includes melting a ferritic/martensitic steel, hot-working the melted ferritic/martensitic steel, normalizing the hot-worked ferritic/martensitic steel at a temperature of about 1050&#xb0; C. to about 1200&#xb0; C., tempering the ferritic/martensitic steel at a temperature of about 600&#xb0; C. or less, and leaving MX precipitates while preventing a MCprecipitate from being precipitated, and cold-working and thermal-treating the ferritic/martensitic steel in a multistage fashion, and precipitating MCprecipitates. Through the above described configuration, the high strength ferritic/martensitic steel that prevents a ductility from being deteriorated even in a high-temperature environment may be manufactured.

Disclosed herein are a nuclear fuel rod for fast reactors, which includes an oxide coating layer formed on the inner surface of a cladding, and a manufacturing method thereof. The nuclear fuel rod for fast reactors, which includes the oxide coating layer formed on the inner surface of the cladding, can increase the maximum permissible burnup and maximum permissible temperature of the metallic fuel slug for fast reactors so as to prolong the its lifecycle in the fast reactors, thus increasing economic efficiency. Also, the fuel rod is manufactured in a simpler manner compared to the existing method, in which a metal liner is formed, and the disclosed method enables the cladding of the fuel rod to be manufactured in an easy and cost-effective way.
