About this question

Why in news

A new SHANTI Rules eligibility clause requiring SMR designs to "already be operational" functions in practice as a market-access filter that currently only Russia's Akademik Lomonosov design can clear, given its six-year commercial head start over Western competitors.

Why for UPSC

UPSC often tests whether aspirants can spot a subtly overstated superlative ("only") planted alongside otherwise accurate facts - a common Prelims trap that rewards careful reading over rote recall.

Prelims summary

Akademik Lomonosov (Russia, operational since May 2020) and China's HTR-PM (operational since Dec 2023) are the world's only two commercially operating SMRs; Indian PHWRs cost less per MW-e than Russian VVERs; the SHANTI Act, 2025 replaced the Atomic Energy Act, 1962, targeting 100 GW nuclear capacity by 2047.
