In this paper, the method fabricating the lower density UO_2 fuelpellet is investigated.
本文介绍了在UO_2粉末中加入造孔剂制备低密度uo_2燃枓芯块的方法。

The solid fuelpellet (a ceramic oxide matrix) is the first barrier that retains many of the radioactive fission products produced by the fission process.
固体的燃料弹（陶式氧化物母体）是第一道防护，隔开裂变过程中产生的裂变放射。

The intense beams produce a powerful shockwave that crunches the fuelpellet at a million miles an hour, generating temperatures of around 100, 000, 000C.
