RAS question

Madras Atomic Power Station (MAPS) Units 1 and 2 are located at:

Correct answer: (D) Kalpakkam.

Madras Atomic Power Station Units 1 and 2 are located at Kalpakkam in Tamil Nadu.

  1. (A)

    Coimbatore

  2. (B)

    Kudankulam

  3. (C)

    Chennai

  4. (D)

    Kalpakkam

Explanation

MAPS refers to Madras Atomic Power Station, and NPCIL's Kalpakkam Site page places it at Kalpakkam in the northern part of Tamil Nadu, on the east coast. The same official page says the Kalpakkam site consists of two 220 MWe units and identifies Madras Atomic Power Station (MAPS) 1 and 2 as Pressurised Heavy Water Reactors, described as 2 x 220 MWe PHWR. That is why Kalpakkam is the precise answer, not the nearest large city or another nuclear station in Tamil Nadu. Unit 1 was commissioned in 1984 and Unit 2 in 1986.

Why the other options are wrong

  • (A) Coimbatore is wrong because it has no nuclear plant, while NPCIL places MAPS 1 and 2 at Kalpakkam.
  • (B) Kudankulam is a different station, KKNPP with VVER reactors, whereas MAPS 1 and 2 are PHWR units at Kalpakkam.
  • (C) Chennai is only the nearest major city; NPCIL's site page identifies Kalpakkam as the MAPS location.

Concept

This tests Indian nuclear power-station mapping: matching a named atomic power station to its site and reactor-type clue. It recurs in RAS Science & Technology because options often mix nearby cities, similarly known nuclear sites and reactor types.
