First nuclear power plant in India Identify the location of India's first commercial nuclear power station (commissioned as TAPS).

Introduction / Context:
Historical knowledge of nuclear installations is common in engineering general studies. India’s first commercial nuclear power plant set the stage for subsequent developments in the nation’s nuclear program.

Given Data / Assumptions:

• TAPS stands for Tarapur Atomic Power Station.
• Commissioned in the late 1960s as India’s first commercial nuclear station.
• Other sites listed host later nuclear facilities or are unrelated.

Concept / Approach:

Matching the acronym and historical commissioning confirms the correct location as Tarapur, Maharashtra. Noting this helps avoid confusion with other reactor sites like Kota (Rajasthan Atomic Power Station) or Kalpakkam (Madras Atomic Power Station).

Step-by-Step Solution:

Verification / Alternative check:

Official records and energy-history sources consistently list Tarapur as India’s first commercial nuclear power station.

Why Other Options Are Wrong:

Kota refers to Rajasthan Atomic Power Station; Bareilly is not a nuclear site; “none of these” conflicts with known facts; Kalpakkam hosts MAPS built later.

Common Pitfalls:

Confusing research reactors with power stations; TAPS is a commercial power plant.

Final Answer:

Tarapur
