Zorluk: ZorDefense and Nuclear Technology

India's nuclear technology program relies heavily on indigenous research reactors for fissile material production, isotope generation, and technological validation. Arrange the following historical Indian nuclear research reactors in chronological order based on the year of their initial criticality, starting from the earliest to the most recent.

  1. 1Apsara (Pool-type research reactor)
  2. 2CIRUS (Canada-India Reactor Utility Services)
  3. 3Dhruva (High-flux heavy water research reactor)
  4. 4KAMINI (Kalpakkam Mini Reactor)

Cevap

The correct chronological sequence from earliest to most recent is: Apsara (1956) → CIRUS (1960) → Dhruva (1985) → KAMINI (1996).
The sequence follows the exact historical timeline of initial criticality dates: Apsara was commissioned first in August 1956, followed by CIRUS in July 1960, Dhruva in August 1985, and KAMINI in October 1996.

Adım Adım Çözüm

1
Identify the criticality date of Apsara
Apsara achieved criticality on August 4, 1956, making it the earliest research reactor in Asia.
Establishes the starting point of the sequence.
2
Identify the criticality date of CIRUS
CIRUS achieved criticality on July 10, 1960, built with Canadian assistance.
Places CIRUS second in the timeline.
3
Identify the criticality date of Dhruva
Dhruva achieved criticality on August 8, 1985, at the Bhabha Atomic Research Centre (BARC).
Places Dhruva third in the sequence.
4
Identify the criticality date of KAMINI
KAMINI achieved criticality on October 29, 1996, at the Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam.
Establishes KAMINI as the most recent reactor among the choices.
