Insert your fuel pellet to melt outside the core
INTO JAPANESE
燃料ペレットを挿入して炉心の外側に溶かす
BACK INTO ENGLISH
Insert the fuel pellets and melt them on the outside of the reactor core
INTO JAPANESE
燃料ペレットを挿入し、炉心の外側に溶かす
BACK INTO ENGLISH
Insert the fuel pellets and melt them on the outside of the reactor core
