fuel rod造句
(31) Japan's nuclear agency said there was a strong possibility that radioactive cesium detected at the plant after the blast was from the melting of a fuel rod. (32) This residual heat decreases over time after the reactor is shutdown, and must be removed by cooling systems to prevent the fuel rod from overheating and failing as a barrier to radioactive release. (33) It is true that part of [the] fuel rod may have been deformed or melting. (34) In this paper the flame spreading rate (Vf), pyrolysis length (lp)and flame structure of PMMA fuel rod in an opposed air flow and quiescent environment were investigated. (35) So the first "type" of radioactive material is the uranium in the fuel rods, plus the intermediate radioactive elements that the uranium splits into, also inside the fuel rod (Cesium and Iodine). (36) "Fuel failure" is a better term to describe the failure of the fuel rod barrier (Zircaloy). (37) The failed fuel assembly identification system is an important safety system which ensures safe operations of reactor and immediate treatment of failed fuel rod cladding.
