Indian nuclear facilities: Where is the Fast Breeder Test Reactor (FBTR) located?

Introduction / Context:
India’s nuclear programme includes research and power reactors across multiple sites. The Fast Breeder Test Reactor (FBTR) is a key facility for demonstrating fast reactor technology and breeding capabilities, important for closing the fuel cycle and utilizing plutonium effectively.

Given Data / Assumptions:

• FBTR refers specifically to India’s sodium-cooled fast test reactor.
• We identify the physical location/site and associated center.

Concept / Approach:
FBTR is situated at the Indira Gandhi Centre for Atomic Research (IGCAR) campus at Kalpakkam, on India’s southeast coast near Chennai (formerly Madras). Other nuclear sites mentioned are significant but house different facilities: Kota is near Rajasthan Atomic Power Station (PHWRs); Trombay (BARC) hosts research reactors and labs; Tarapur hosts early BWRs and PHWRs, not FBTR.

Step-by-Step Solution:

Verification / Alternative check:
Published information on India’s nuclear programme consistently lists FBTR at Kalpakkam, alongside PFBR (Prototype Fast Breeder Reactor) development.

Why Other Options Are Wrong:

• Kota (Rajasthan): PHWR units at RAPS, not FBTR.
• BARC (Trombay): Research reactors like Apsara and Dhruva; not FBTR.
• Tarapur: Early BWRs and later PHWRs; not FBTR.

Common Pitfalls:
Confusing FBTR with PFBR or with research reactors at Trombay; each has distinct technology and location.

Final Answer:
Kalpakkam (near Madras)
