Context: Experts have cautioned that current economic models of nuclear fusion are overly optimistic, with costs unlikely to decline as rapidly as projected, raising concerns about its near-term viability as a major energy source.
- Nuclear energy is the power stored within the nucleus (core) of an atom, released by splitting atoms (fission) or joining them (fusion).
- Nuclear fusion: Process where light nuclei combine to release energy; powers stars like the Sun in the Universe.
- Unlike fission, fusion produces minimal radioactive waste and no chain reaction risk.
- Current status: However, Fusion technology is still experimental with no commercially viable power plants yet. Countries are using Nuclear fission for power generation.
- Experience curve: It is a Concept that states costs fall as cumulative production increases.
- However, experts warn that high capital cost and technological complexity remain major barriers for a longer term than the current investments in Nuclear fusion technology assume.
