APAKAH MAKSUD CONTROL ROD dalam CORSICA?
Rod kawalan
Batang kawalan adalah rod yang digunakan dalam reaktor nuklear untuk mengawal kadar pembelahan uranium dan plutonium. Mereka diperbuat daripada unsur-unsur kimia yang mampu menyerap banyak neutron tanpa melepaskan diri, seperti boron, perak, indium dan kadmium. Oleh sebab unsur-unsur ini mempunyai bahagian silang yang berbeza untuk neutron-energi yang berbeza-beza, komposisi rod kawalan mestilah direka untuk spektrum neutron reaktor yang sepatutnya dikawal. Reaktor air ringan dan reaktor air berat beroperasi dengan neutron "panas", sedangkan reaktor pembiak beroperasi dengan neutron "cepat".
Definisi control rod dalam kamus Corsica
Takrif rod kawalan dalam kamus adalah salah satu daripada beberapa rod atau tiub yang mengandungi penyerap neutron, seperti boron, yang boleh dimasukkan ke dalam atau ditarik balik daripada inti reaktor nuklear untuk mengawal kadar tindak balasnya.
