Question

(i) Why is the core of a nuclear reactor one of its

most important part?

(ii) Why should nuclear fission precede a nuclear fusion?​

Answer 1

Answer:

1.The fuel will be low-enriched uranium contained in thousands of individual fuel pins. The core also contains structural components, the means to both moderate the neutrons and control the reaction, and the means to transfer the heat from the fuel to where it is required, outside the core

2.While fusion occurs two or more smaller atoms fuse together, creating larger, heavier atom. Once the fusion reaction begins, energy liberated can maintain the minimum required temperature and the fusion reaction continues. That's why nuclear fission precede nuclear fusion and is more sustainable.

Answer 2

Explanation:

Ans.1) Typically, the fuel will be low-enriched uranium contained in thousands of individual fuel pins. The core also contains structural components, the means to both moderate the neutrons and control the reaction, and the means to transfer the heat from the fuel to where it is required, outside the core.

Ans.2) While fusion occurs two or more smaller atoms fuse together, creating larger, heavier atom. ... Once the fusion reaction begins, energy liberated can maintain the minimum required temperature and the fusion reaction continues. That's why nuclear fission precede nuclear fusion and is more sustainable.
